Being overweight or obese can have numerous negative impacts on your health. One of the most significant impacts is its impact on fertility. Overweight women are more likely to struggle with fertility issues compared to women with a healthy body weight.

In this article, we will discuss the reasons why overweight women struggle with fertility.

Hormonal imbalances

One of the biggest reasons for fertility issues in overweight women is hormonal imbalances. Higher levels of fat cells in the body disrupt the hormonal balance, which can cause irregular periods and ovulation.

Women who are overweight are more likely to experience an increase in estrogen levels, leading to a decrease in the production of progesterone. This hormonal imbalance can interfere with ovulation, making it harder for women to conceive.

Irregular menstrual cycles

Overweight women are prone to having irregular menstrual cycles, which can hinder their chances of becoming pregnant. Weight gain can cause fluctuations in menstrual cycles, making it harder for women to predict when they are ovulating.

As a result, they may struggle to conceive due to the unpredictability of their menstrual cycles.

Polycystic Ovary Syndrome (PCOS)

Polycystic Ovary Syndrome is a condition that affects women of reproductive age. It is more common in women who are overweight or obese. Women with PCOS often have high levels of insulin and androgens, which can interfere with ovulation.

As a result, they have irregular periods, making it harder for them to conceive. Weight loss can help improve insulin sensitivity and hormone balance, making it easier for women with PCOS to conceive.

Endometrial cancer

Endometrial cancer is a type of cancer that occurs in the lining of the uterus. It is more common in women who are overweight or obese. Overweight women are at a higher risk of developing endometrial cancer due to the excess estrogen in their body.

The risk of developing endometrial cancer in overweight women increases with age. Women who are overweight and have irregular periods are at a higher risk of developing endometrial cancer.

Increased risk of gestational diabetes

Gestational diabetes is a form of diabetes that affects pregnant women. Overweight women are at a higher risk of developing gestational diabetes compared to women with a healthy body weight.

Gestational diabetes increases the risk of complications during pregnancy and childbirth, such as premature birth and preeclampsia. Women with gestational diabetes are also at a higher risk of developing type 2 diabetes later in life.

Increased risk of miscarriage

Overweight women are at a higher risk of miscarriage compared to women with a healthy body weight. The risk of miscarriage increases in women who are obese and have a BMI greater than 30.

The risk of miscarriage increases due to hormonal imbalances, inflammation, and impaired glucose metabolism.

Impaired egg quality

Overweight women are more likely to have impaired egg quality, which can make it harder for them to conceive. Higher levels of fat cells in the body can cause oxidative stress, leading to impaired egg quality.

As a result, the chances of becoming pregnant decrease as the quality of the eggs decreases.

Increased risk of hypertension and pre-eclampsia

Overweight women are at a higher risk of developing hypertension and pre-eclampsia during pregnancy. These conditions can cause complications during pregnancy and increase the risk of premature birth.

Women who are overweight or obese are also more likely to require a cesarean section delivery.

Increased risk of birth defects

Overweight women are at a higher risk of giving birth to infants with birth defects. The risk of birth defects increases in women who are obese and have gestational diabetes.

The most common birth defects associated with maternal obesity are neural tube defects and heart defects.

Response to fertility treatments

Overweight women who undergo fertility treatments are less likely to respond to treatment compared to women with a healthy body weight.

Studies suggest that overweight women have lower success rates with fertility treatments such as in vitro fertilization (IVF). This is due to hormonal imbalances and impaired egg quality.
