Do overweight women have more trouble getting pregnant?

Yes, being overweight can make it harder for women to get pregnant. Excess body weight disrupts hormone balance, particularly by increasing estrogen and insulin levels, which can interfere with ovulation and menstrual regularity. Conditions like polycystic ovary syndrome (PCOS) are also more common in women with higher body weight and are a leading cause of infertility. Even modest weight loss of 5-10% can significantly improve fertility outcomes.

A free, instant, online symptom check can help you identify possible underlying causes—like hormonal imbalances or PCOS—and guide you on what to do next.

Explanation

Being overweight can make it harder for women to get pregnant. This is because extra weight can change how a woman's body works.

How Weight Affects Fertility

Hormone Changes: Extra weight can change hormone levels, which can affect a woman's menstrual cycle and ovulation.
Ovulation Problems: Ovulation is when an egg is released from the ovary. If this doesn't happen regularly, it can be harder to get pregnant.

Health Impact

Insulin Resistance: Being overweight can lead to insulin resistance, which affects how the body uses sugar and can impact fertility.
Inflammation: Extra fat can cause inflammation in the body, which can also affect fertility.

In summary, being overweight can change many things in the body that are important for getting pregnant.
