Types of High Blood Pressure during Pregnancy

Blood pressure is the force of blood that pushes against the walls of your arteries each time the heart contracts to pump the blood through each parts of the body. Arteries are blood vessels that transport blood from your heart to other parts of the body. If the pressure in your arteries becomes too high, this condition is known as have high blood pressure or hypertension. Hypertensioncan lead to health problems and pose extra pressure on your kidneys and heart, however in most cases hypertension is preventable and treatable. Uncontrolled or severe hypertension during pregnancy when not appropriately treated can cause health risk for you and your fetus. Complications arise from high blood pressure in pregnancy have become more common over the years.Some women have high blood pressure before they get pregnant, others may have high blood pressure for the first time during their pregnancy. Approximately 8 percent of women have some kind of high blood pressure during pregnancy. There are four types of high blood pressure in pregnant women:

  • Chronic hypertension: Chronic hypertension is high blood (over 140/90) pressure that develops before the 20th week of pregnancy or is present much before the woman becomes pregnant or continue to have it after delivery. High blood pressure usually doesn’t have symptoms so it is possible that a woman has high blood pressure for a long time before she gets pregnant, but she doesn’t aware about it until she has first prenatal check-up. Chronic hypertension usually treated with blood pressure medication.
  • Gestational Hypertension: Gestational Hypertension is a high blood pressure that develops after week 20 in pregnancy without the presence of protein in the urine or other changes in liver function.This form of high blood pressure is typically temporary and normally to go away after delivery.However, it can increase the risk of developing high blood pressure later in women life.In some cases, the blood pressure will remain high after the delivery, which results in chronic hypertension. Some women with gestational hypertension finally develop preeclampsia in her later age.
  • Preeclampsia: Preeclampsia is a high blood pressure condition when a pregnant woman has high blood pressure usually after 20 weeks of pregnancy or after giving birth. It is a serious condition that can associate with signs of damage to other organ systems, including liver, kidneys, blood or brain. Untreated preeclampsia can lead to serious health problems for both mother and baby and can develops seizures (eclampsia). Previously, it was diagnosed only if a pregnant woman had protein in her urine and high blood pressure but now it’s quite possible to have preeclampsia without having protein in the urine. Signs and symptoms of preeclampsia include high blood pressure, excessive swelling of the face and hands, weight gain due to fluid retention, blurred vision, severe headaches, sensitivity to light, dizziness, shortness of breath, nausea and having protein in the urine.
  • Chronic hypertension with superimposed preeclampsia: This health complication occurs in women with chronic hypertension before pregnancy. In this condition women develop deterioration high blood pressure and protein in the urineduring pregnancy.

Pregnancy and Opioids

Some women required medicines while they are pregnant. But consumption of most of the medicines are not safe during pregnancy. Many medicines create risks for you and for your baby.It can cause problems for you and your baby whiles you are pregnant, when you missed Opioids. Opioids sometimes known as narcotics are a type of drug. They include strong prescription pain relievers such as hydrocodone, oxycodone, tramadol and fentanyl. The illegal drug heroin is also an opioid.A doctor provider may give you a prescription Opioid to reduce pain caused due to a major injury or surgery. You also may be advised, if you have severe pain from health conditions like cancer. A doctor may prescribe them for chronic pain.

Prescription opioids used for pain relief are usually safe when prescribed by your doctor and taken for a short time. However, dependency and addiction of Opioid can have a potential risk. These risks usually increase when these medicines are misused. Misuse means you are taking someone else’s Opioids or you are not taking the medicines according to yourdoctor’s instructions or you are using high doses of it.

The possible risks of taking opioids during pregnancy?

Taking opioids during pregnancy can cause problems for you and your baby. The possible risks are:

  • Neonatal abstinence syndrome (NAS): Withdrawal symptoms (vomiting, diarrhea, irritability, seizures, fever, and poor feeding) in newborns baby.
  • Loss of the baby either miscarriage (before 20 weeks of pregnancy) or stillbirth (after 20 or more weeks).
  • Gastroschisis – A birth defect of the newborn child’s abdomen, where the intestines stick outside of the body through a hole beside the belly button.
  • Neural tube defects: Birth defects of the Spinal Cord, Brain or Spine.
  • Stunted growth: Which results in low birth weight.
  • Congenital heart defects: Health issues with the structure of the baby’s heart.

Some women require to take opioid pain medicine during her pregnancy’s days. You should first discuss the risks and benefits, if your doctor suggests that you need to take opioids during pregnancy. Then if you and your doctor both decide that you need to take the opioids, you should work together to try to minimize the risks. Some of the ways to minimize the risks are:

  • Consume these for the shortest time possible.
  • Taking as much as least dose that will help you.
  • Meet your doctor for all your follow-up appointments.
  • Contact your doctor as soon as possible if you have side effects.
  • Carefully following your doctor’s instructions for taking the medicines.

Treatments for opioid disorders in pregnancy

If you are pregnant and have an opioid use disorder, do not stop consumption of opioids suddenly. Consult your doctor so you can get help.The treatment for opioid use disorder is medication-assisted therapy (MAT). MAT includes counseling and medicine:

  • Medicine: Medicine can reduce your withdrawal and cravings symptoms. For pregnant women, doctors usually use either methadone or buprenorphine.
  • Counseling: It includes behavioral therapies, which can help you to build healthy life skills,help to change your attitudes and behaviors related to drug use and for getting useful prenatal care guidance.

How is infertility diagnosed in Female?

A woman should be evaluated for any suspected infertility if she is unable to get pregnant after having 12 months of regular and unprotected sexual intercourse. A health care provider will ask basic questions about women health history for exploring root causes of infertility during evaluating of a woman’s fertility health. These questions may include:

  • History of past pregnancies
  • History of irregular menstrual cycles
  • History of abnormal vaginal bleeding or discharge
  • Known or suspected problems with the tubes, uterus or other problems in the abdominal cavity
  • Prior miscarriage cases
  • If she has abnormal vaginal bleeding or discharge
  • If she has a history of previous pelvic surgery or pelvic infection
  • Known or suspected male infertility problems

The evaluation should include the male as well as female partners and should be performed in a focused way to find all relevant factors for infertility. The least invasive methods should be tried first. The following tests may be performed as part of the infertility evaluation:

Hysterosalpingogram (HSG):  A hysterosalpingogram (HSG) is a procedure that uses an X-ray to see if the fallopian tubes are open and to if the shape of the uterine cavity is normal. This procedure usually takes less than 5 minutes and you can go home the same day. This procedure usually has been performed after period but before the ovulation, since it’s less likely that pregnancy occurred during this time.

Transvaginal Ultrasonography: An ultrasound probe is inserted into the vagina that causes sound waves to bounce off organs inside the pelvis to check the uterus and ovaries for abnormalities such as fibroids and ovarian cysts. These sound waves form echoes that are sent to a computer which produces a picture called a sonogram. This test is also called transvaginal sonography and TVS.

Male Partner Semen Analysis: Semen analysis is an important part of the infertility evaluation, although it is obtained from the male partner. A semen analysis provides information about the shape, movement and number of the sperm. A semen analysis is still important even if the male partner has fathered a child before.

Other Blood Tests: Other blood tests can be useful to check prolactin and thyroid-stimulating hormone (TSH) and to identify thyroid disorders and hyperprolactinemia which may cause problems with fertility, repeated miscarriages and menstrual irregularities. A blood test done around day 23 of the woman’s menstrual cycle can identify the amount of a hormone known as progesterone. This test detects whether ovulation has occurred and whether the ovaries are producing normal amount progesterone.

Laparoscopy: Laparoscopy is a surgical diagnostic procedure in which a lighted telescope-like instrument (called laparoscope) is inserted through the wall of the abdomen into the pelvic cavity used to examine the organs inside the abdomen. Laparoscopy allows your doctor to view and analyze inside your body in real time, without open surgery. Your doctor also can receive biopsy samples during this procedure. Laparoscopy should not be the first option in the evaluation of a female patient, as it involved high potential surgical risk and cost. It may be recommended depending on the woman’s health conditions and the results of other tests. How IVF can be a big life changer?

How to Improve Female Fertility?

Many environmental and genetic factors can affect fertility in men and women. However, it is quite possible to improve fertility capability using various natural methods. By following below mentioned methods, a woman can increase their chance of getting pregnant and can able to set the stage for a healthier pregnancy:

Managing stress

Stress is normally bad for our health no matter the circumstance, but it can have an even deeper hampering effect if you’re trying to conceive. For many women, trying to get pregnant can be stressful and stress can further reduce fertility. Do your best to reduce and manage anxiety and tension. Stress level can be measured by alpha-amylase which is directly linked to stress. A study showed that women with higher alpha-amylase levels may have a lower chance of getting pregnant naturally.

Women can increase their fertility by engaging in stress reduction activities. It is suggested that, women who wisely manage their anxiety and depression have a higher chance of becoming pregnant than those who do not. You can also try relaxation techniques like yoga, acupuncture or meditation for managing stress level. Just like you include cooking dinner and walking the dog in your daily schedule, also include stress reducing activities a priority in this list.

Maintain a Healthy Diet and Weight

Antioxidants like zinc and folate can considerably improve fertility for both men and women. Include foods rich in antioxidants (vitamins C and E, folate, beta-carotene and lutein) in your diet like fruits, vegetables, nuts and grains. Including healthy fat in your diet is also important for boosting fertility.

You can keep your reproductive cycle in balance, by ensuring that you’re not overweight or underweight. Obesity can harm your health in many ways, for example it can intervene with your ovulation. But women who are substantially underweight also possess a higher risk of ovulation problems. Whether you trying to lose or gain weight, try to achieve a healthy body mass index (BMI) to help maintain normal ovulation. BMI range of 19 to 24 indicates a healthy weight. Anything below or above this range should be discussed with your health care provider. A medical researcher found that women whose BMI is in the overweight or obese category have a much harder time becoming mother.

Stop smoking and reduce alcohol consumption

Smoking tobacco can interrupt hormone levels in your body and cause menopause to occur at much earlier age. Some study shows that smoking decreases your supply of eggs and ages the ovaries. It also increases the risk of ectopic pregnancy and miscarriage and also harms your cervix and fallopian tubes. Frequent drinking before pregnancy is directly linked to ovulation disorders. While you’re pregnant or planning to become pregnant, it is highly recommended not to smoke and drink alcohol at all to keep risks to your baby to a minimum.

Practice safe sex

Having unprotected sex with multiple partners increases your chances of sexually transmitted diseases (STDs). These diseases can permanently damage your uterus and fallopian tubes. So try to avoid these practices. Surrogacy Vs Adoption

Ovulation Cycle Tracking

Ovulation cycle tracking is a simple procedure that can be helpful to recognize which days are most fertile to conceive. It is done by tracking women hormone cycle to predict when ovulation is probably going to occur.

The rise of hormones from pituitary gland known as “Luteinising Hormone”, trigger the ovulation. This generally occurs 24 hours before ovulation.

Your fertility specialist can detect this hormone surge by carrying out simple blood and ultrasound tests. The specialist then can able to advise you of the suitable time to have sex that will surely give you the best chance of conception. It doesn’t any medicines or invasive fertility treatments and it can provide the far better prediction than the home ovulation predication kits. This procedure only require the female partner needs to visit the clinic for cycle tracking, so there is no involvement of male partner during the procedure and they can remain stay at home.

Importance of sex timing for successful conception

If you’re trying to fall pregnant, the timing of when you and your partner have sex is critical as many couples get this wrong.

The timing of when you and your partner have sex is very much important when you’re trying to get pregnant, but many couples are not aware about this fact. Your menstrual cycle is the most fertile time which can results in the ovulation, before the egg is released from the ovary.

The egg can only survives for just 24 hours after ovulation, while sperm continue fertilizing capability for coming two to three days in the fallopian tubes. Due to this reason, the fertility specialist recommend couples to have sex every two days all around the female’s fertile window which can results in the successful ovulation, as the sperm are ready and waiting for the egg to fertilize when the female ovulates.

You are most likely to miss your fertile window and the opportunity for successful conception in a particular month if you are waiting trying to have sex at exactly the time of ovulation. Due to this fact, tools that help you to identify when you are going to ovulated are only useful to predict when you will possibly going to ovulate next month, assuming your cycles are regular.

Home ovulation kits Vs clinical ovulation tracking

You can identify more accurate and comprehensive overview of your cycle and general fertility possibility by undertaking a combination of ultrasounds and blood tests.

The most home ovulation tests that only measure the luteinising hormone (LH), but in Ovulation Cycle Tracking the specialist measure the quantity of progesterone, estrogen and LH present throughout cycle which enable them to expect ovulation earlier and use the ultrasounds can confirm that there are actually follicles developing.

Dr. Shivani Sachdev Gour (gynecologist and infertility specialist) can help you to conceive naturally with the help of Ovulation Cycle Tracking. She will provide you with professional expert advice regarding this procedure and identify any underlying problems as per your requirement. You can get a valuable advice from her at SCI Healthcare and SCI IVF Hospital and Multispecialty Center.

How Is ICSI Performed?

Intracytoplasmic Sperm Injection (ICSI) is a micromanipulation procedure involves the direct injection of a single sperm into an egg to attempt fertilization. It usually used with male infertility or patients with previous IVF failure. There are generally five simple steps are involved in ICSI procedure which include the following:

  • The mature egg has been collected in a specialized glass tube.
  • A hollow, very delicate and sharp needle is used to pick up and immobilize a single sperm.
  • With care, the needle is then inserted through the cytoplasm of the egg and shell of the egg.
  • The sperm is carefully injected into the cytoplasm and the needle is than removed.
  • Following day, the eggs are checked further for the sign and evidence of normal fertilization.

The embryo transfer process is followed to physically plant the embryo in the woman’s uterus, once the all steps of ICSI are completed and fertilization become successful. Then it is a event to wait and watch for early pregnancy symptoms. The doctor may use ultrasound reports or a blood test to verify if implantation and pregnancy has occurred successfully.

Risks associated with ICSI

There are also several risks associated with ICSI procedure. The first risk is that, during the ICSI procedure, as a result of the needle insertion a small number of eggs (approximately less than 5 percent) may be damaged. Second, the overall risk of having a baby with a chromosomal abnormality in the X or Y chromosomes is 0.8 percent (or eight per 1000) which is nearly four times the average found with spontaneous conception. At present, we are unable to figure out the exact reason for this increased risk. It is important to know the following problems can be involved with sex chromosome abnormalities:

  • There may be a requirement of surgery for affected infants with heart problems
  • Increased risk of miscarriage
  • Increased risk of learning disabilities or behavior abnormality
  • Increased risk of serious infertility issues in your children during their adulthood
  • The risk of having a chromosomal abnormality like Down’s syndrome is basically not increased with ICSI procedure but increases with maternal age.

If a successfully fertilization takes place, a women chance of giving birth to a single baby, twins, or triplets is the same if they have IVF with or without ICSI. Several studies have indicated the issue of developmental delays in children born with ICSI. But, there is no definitive proof that this is the case.

How successful is ICSI?

Chances of successful fertilization with this procedure vary between patients (particularly according to the age of the woman). Fertilization rates of nearly  80 percent of all eggs injected which is equivalent to fertilization with normal sperm are currently being achieved, and high pregnancy rates are seen with ICSI procedure for the couples suffering male factor infertility.

The most important indicator of ICSI success found to be the fertilization rate achieved during the ICSI procedure. The fertilization rate at SCI Healthcare and SCI IVF Hospital and Multi-specialty Center is exceptional high (currently 80 to 85 percent). This indicates, on average, eight out of every 10 eggs will fertilize in proper and normal way.

Significant Advantages of Frozen Embryos

Frozen embryos offer patients who are suffering from infertility problems, an opportunity to expand their families in the future. There is no decline in embryos quality while they are in frozen state, therefore it maintain their reproductive potential. The embryos are associated with the age of the woman’s egg at the time of its fertilization; this can be an additional advantage. If a 35 years old patient goes through a full IVF cycle, she will be using eggs from her 35 years old with subsequent FET’s at the age of at 37 and again at 39. Younger eggs result in higher chances of chromosomal normalcy and higher pregnancy rates, so younger eggs are always preferred.

Women suffering from polycystic ovary syndrome (a hormonal disorder that often leads to fertility problems) can improve their chances of a successful pregnancy with the help of frozen embryos rather than fresh ones for in-vitro fertilization. Historically, the use of fresh embryos is preferred over that of frozen embryos, but study suggested that elective embryo freezing followed by frozen embryo transfer is an effective treatment for women with polycystic ovary syndrome. According to the studies, the success behind frozen embryos depends on the fact that frozen embryos take longer than fresh embryos to implant in the uterus. This is necessary for the better fertility environment because it allows hormone levels in the uterus to return to normal before the embryo is implanted. Frozen embryos increases pregnancy success rate in women, additionally women treated with frozen embryos also had fewer instances of hyperstimulation syndrome(a condition in which the ovaries swell and become painful and may also results in  other pregnancy complications) than women given fresh embryos. If a woman can able to freeze and store their embryos while attempting a fresh cycle transfer, and if accidently the fresh cycle is unsuccessful, she always has an option to try again without undergoing another ovarian stimulation or egg retrieval. Therefore, her cumulative pregnancy rate increases overall from one IVF cycle. Multiple frozen embryo transfer or FET cycles are less costly than fresh IVF cycle because medication is relatively less and there is no egg retrieval or anesthesia involved in this process. With Single Embryo Transfer or SET there may be an opportunities for multiple FET cycle after just one egg retrieval which again increases the cumulative pregnancy rate from one IVF.  FET cycles can be easily scheduled when it is more suitable and convenient for most of women. After scheduling FET, women are prescribed oral estrogen so that the uterine lining become ready for the transfer and this is administered only once every three days. Progesterone injections are applied, so that the women body can able to support a successful pregnancy. Daily intramuscular progesterone can be prescribed later in the cycle.

But at the same time, there are also few risks associated with women who received frozen embryos. It slightly increase risk of potentially dangerous high blood pressure during pregnancy and can increase death rate in newborn babies.

Laser Assisted Hatching

Laser Assisted Hatching is a process where a low energy laser beam is used to break the outer layer of the Zona Pellucida (the outer layer or shell that surrounds an embryo). The main purpose of laser assisted hatching is to allow the embryo to hatch more easily from its outer layer or shell. All pregnancies must result in successful hatching, whether naturally occurring or as a result of any assisted hatching technique such as in-vitro fertilization to enable embryos to implant in the lining of the uterus for further fertilization process. The Zona plays an important vital role in fertilization process as only one sperm can perforate the Zona and fuse with the egg for successful fertilization. The laser used to break the outer layer shell of the embryo is non-contact which means that embryo is not in direct contact with laser. The opening of embryo is increased with the help of laser. The whole procedure is carried out with latest technologies thorough precision and delicacy which positively improves and ramps up pregnancy rates among women.

Laser Assisted hatching involves considerably less time and protects the embryo from toxic chemicals so that the potential effect of these factors reduces and the stress placed upon the embryo during the whole process. In some cases, outer layer of the Zona Pellucida is abnormally thick or hardened with the freezing and thawing process. The possibility of the embryo to attaching or implanting into the wall of the uterus directly depends on the less difficulty faced by the embryo during hatching. Pregnancy cannot successfully happen unless the embryo hatches and implants and Laser Assisted Hatching can play a vital role in achieving these essential steps.

At the SCI Healthcare and SCI IVF Hospital of New Delhi, laser assisted hatching is offered and recommended for frozen embryo transfers by Dr Shivani Sachdev Gour (one of the best gynecologists and infertility specialist based in Delhi).

Who is recommended for Laser Assisted Hatching?

Recent research showed that women who have undergone repeated unsuccessful IVF treatments can increase their chances of a successful pregnancy with Laser Assisted Hatching procedure. But Laser Assisted Hatching can be helpful for any patient and it is most likely to be best suited for women:

  • Who are older than 37 years of age thus produce eggs with a harder Zona Pellucida.
  • With a high Follicle Stimulating Hormone (FSH) level early in their cycle.
  • Who have a tendency to produce a harder or thicker Zona Pellucida
  • Who have frozen embryo transfer
  • Who have poor embryo quality
  • Who have mild elevations in their day 3 FSH levels

Advantages of laser-assisted hatching

A Laser Assisted Hatching considered being the best to other forms of assisted hatching due to the below reasons:

  • Exact and fast control over drilling of the shell opening
  • Minimal handling of the embryo during the procedure
  • It is more safe procedure, with no negative effects on the embryo
  • Assisted hatching may be clinically useful in patients with a poor prognosis, including those with two failed IVF cycles and poor embryo quality and older women than 38 years of age. At SCI Healthcare and SCI IVF Hospital and Multi-specialty Center, your doctor can further guide you to see if assisted hatching may optimize your IVF outcome.

Why Vitro Fertilization (IVF) is performed

In-vitro fertilization (IVF) is a new medical procedure to treat infertility or genetic problems. IVF help the couples with infertility who wants to have their own baby. It is recommended to try other fertility treatments first before going for IVF treatment, as it is very expensive and invasive.  If you decided to go for IVF treatment, you and your partner must try less invasive treatment options before attempting IVF; including taking fertility drugs to increase production of eggs or intrauterine insemination (it is a procedure in which sperm are transferred in uterus at the time of ovulation).  If parents run the risk of passing a genetic disorder on to their offspring, IVF can be helpful in such condition. A medical lab can test the embryos for genetic defects or abnormalities. After that, doctor only implants healthy embryos without genetic defects.

IVF considered as a primary treatment for women suffering from infertility over age of 40 years. It can be adopted if you have certain heath problems. IVF can be beneficiary, if you or your partner has:

Damage or blockage of fallopian tube:  If the fallopian tube get damaged or blocked, it become  difficult for an egg to be fertilized or for an embryo to travel to the uterus for further fertilization. 

Ovulation disorders: If ovulation is absent or infrequent, fewer eggs will be available for further fertilization. 

Premature ovarian failure: Before the age of 40 years, many women suffered from premature ovarian failure which is the loss of normal ovarian function. If your are suffering from premature ovarian failure, the ovary won’t produce normal amounts of the hormone estrogen or have eggs to release regularly. 

Endometriosis: Endometriosis arises when the uterine tissue implants and grows outside of the uterus. Endometriosis often affects the normal function of the fallopian tubes, ovaries and uterus. 

Uterine fibroids: Many women in their 30s and 40s suffered from fibroids which is a benign tumor in the wall of the uterus. Fibroids can create problem with implantation of the fertilized egg. 

Impaired sperm function or production: Low-average sperm concentration, poor mobility of sperm (weak movement), or abnormalities in sperm quality, size and shape can make it difficult for sperm to fertilize an egg for further fertilization. If your partner is suffered from any of these semen abnormalities, he must need to see a specialist to determine if there are correctable problems or underlying health concerns for the further IVF procedure. 

Unexplained infertility:  No cause of infertility can also identified despite evaluation for common causes. 

Genetic disorder:  If you or your partner carries a risk of passing on a genetic disorder to your offspring, you may be recommended for having pre-implantation genetic diagnosis. It is a procedure that involves IVF. After the eggs are successfully harvested and fertilized, few tests can be performed to screen for certain genetic problems. Generally not all genetic problems can be found in these tests. The embryos that don’t show identified abnormalities of problems can be transferred to the uterus.

What is High-Risk Pregnancy?

A high risk pregnancy is one that requires specialized extra care from specially trained providers in order to have a healthy pregnancy and baby. It can threaten the life or health of the mother or her child. This is often arises, if you suffer from a chronic illness or have other factors and conditions that convert your pregnancy in the high risk category. Several other factors can make a pregnancy high risk, for example mother’s age and lifestyle, existing health conditions of the mother and some significant health issues that occurred before or during pregnancy. Some pregnancies become high risk as they grow, while for a variety of reasons, some women are at increased risk for risky pregnancy even before they get pregnant. It is likely that problems may prevail with both mother and the baby during the pregnancy, birth process or even after the delivery of the child. For both the mother and the baby, the problems can be minor or life threatening in severity, which require additional monitoring and care from your doctor. 

Risk factors for a high-risk pregnancy

Sometimes a high-risk pregnancy is the result of a medical condition present before pregnancy. Specific factors that might contribute to a high-risk pregnancy include:

Existing health conditions: For example high blood pressure, being HIV-positive or diabetes.

Obesity and overweight: Most people already familiar with the facts that obesity increases the risk for high blood pressure or gestational diabetes. Additionally it can also increase the risk of cesarean delivery, preeclampsia, stillbirth or neural tube defects. Researchers have suggested that obesity can raise infants’ risk of having heart problems at birth by 15%.

Multiple pregnancies: If a women carrying more than one fetus – twins or higher-order multiples, the risk of complications will be high as compared with single pregnancy. Common complications include preterm birth, premature labor and and preeclampsia. It is recorded that more than one-half of all twins and 93 percent of triplets are born at less than 37 weeks’ gestation.

Young or old age of mother: Pregnancy in teens and women with age more than 35 years older increases the risk for gestational high blood pressure or preeclampsia.

Medical history:  A history of diabetes, heart disorders, and chronic hypertension, breathing problems such as poorly controlled asthma, infections, and blood-clotting disorders such as deep vein thrombosis can considerably enhance pregnancy risks.

Poor lifestyle: Smoking cigarettes, taking illegal drugs and drinking alcohol can put a pregnancy at high risk.

Surgical history: A history of surgery on your uterus including, multiple abdominal surgeries, multiple C-sections or surgery for uterine tumors (fibroids) can increase chances for pregnancy risks.

Pregnancy complications: Various health complications that develop during pregnancy can also increase pose risks. For examples an abnormal placenta position, Rh (rhesus) sensitization and fetal growth less than the 10th percentile for gestational age.

Women with high-risk pregnancies should require extra care from a special team of health care providers to ensure the best possible pregnancy results. Some Important Tests before Planning a Pregnancy after Miscarriage
