Obesity and Fertility

In this article about Obesity and Fertility, Professor David Kerrigan tells us how conception is not always as easy as people are led to believe.

Trouble conceiving can cause emotional stress and upset for both parties. There are various reasons why a woman may have trouble with fertility, one issue being her weight.

There is an obesity epidemic in the UK; 64% of adults are now classified as being overweight or obese, with rates only predicted to increase. Along with health complications including increased risks of coronary heart disease, certain types of cancer and type 2 diabetes, obesity significantly impacts upon women's fertility and ability to conceive. More than a quarter of women in the UK are obese, with a body mass index (BMI) of 30 or over *, which is a common problem amongst women of reproductive age. For these women, they are often less fertile due to their weight and/or have polycystic ovaries syndrome (PCOS) which influences fertility, the release of eggs, hormonal changes, sexual activity and libido. Obesity does not cause PCOS but exacerbates it, making it more difficult to get pregnant.

Negative impacts of obesity on fertility and pregnancy include: problems with natural conception, miscarriage, long term health problems of both the mother and baby due to increased rate of birth defects, pregnancy complications and the possibility of disease later in life**.

A new report, published by the Royal College of Obstetricians and Gynaecologists, has found that weight-loss surgery is often beneficial to overweight women wishing to become pregnant but who are having trouble in doing so. While weight-loss surgery has proved hugely successful for both men and women, for women it can alleviate symptoms of PCOS and reduce pregnancy complications including risk of miscarriage, gestational diabetes, hypertension, macrosomia (large baby) and congenital abnormalities.

As with any patient, male or female, opting for a weight-loss procedure, there must be evidence of attempts to lose weight through a healthy, calorie-controlled diet and increased exercise. Weight-loss surgery should therefore not be looked upon as the only way to improve fertility but as an option.

It is vitally important for women to start their pregnancy in optimal health, at a healthy weight and to maintain this during and after their pregnancy. Weight loss surgery is far from an easy option. But we also know that losing weight through diet and exercise doesn't work for everyone.
