Obesity

Obese Women Pregnancy Miscarriage

Studies have revealed that women who are overweight during and before being pregnant are at a greater risk of having a miscarriage. The research conducted revealed that there is a direct link between the BMI and miscarriages caused to these women. In this article, we will be discussing some of the reasons which can lead to miscarriage in obese pregnant women.

Reasons Which Can Cause Miscarriage In Obese Women

Obese women suffer from many hormonal problems like excess of estrogen secretion and polycystic ovaries (PCOS). Those women who have an excess of estrogen secretion suffer from infertility, as the ovulation is not adequate in their body, which in turn results in luteal phase defect. Luteal phase defect is the time span between the ovulation and menstruation; this is normally 14 days. The duration of this phase gets disturbed due to various reasons and obesity being one of the primary reasons affect hormones which play an important role in the luteal phase.

Those women who suffer from PCOS have a greater risk of having a miscarriage. This is because such women have higher levels of LH. The elevated levels of LH in the body of the pregnant women can affect the growing fetus, thus resulting in a miscarriage. Even though excess weight has nothing to do with miscarriage itself, PCOS which is mostly present in all overweight and obese women contribute to the increased probabilities of miscarriage. Therefore hormonal imbalance is associated with pregnancy loss. Adequate treatment will help in reversing the situation.

Other risks associated with obesity during pregnancy

  • Obesity causes several problems during pregnancy. Here are some of the dangers which have been observed by various researchers.
  • Obese women are most prone to problems related to infertility and other pregnancy-related complications, including gestational diabetes, blood clots and high blood pressure.
  • Section delivery is more common in obese mothers when compared to women with a normal weight.
  • Studies indicate that the risk of a woman’s chances of having a baby with neural tube defects are increased two times by obesity, and even recommended folic acid intake does not fully protect against this increased risk.
  • When compared with non obese women, obese women have a greater risk of complications arising during pregnancy.

Research states that obese mothers are more likely to give birth to babies with some kind of structural birth defect, such as missing arms and/or legs, malformed hearts and badly developed spinal cords.
