There is a weight range that is considered to be ideal for fertility which is based on your Body Mass Index (BMI). A BMI of 19-25 is considered to be within the normal range. We know that being overweight or underweight can reduce your chances of conceiving.

Women who are underweight often experience problems with ovulation and their periods may stop completely- this is known as amenorrhoea. Therefor we know that the body does need a certain amount of fat to conceive.

Being overweight also effects ovulation and fertility so it’s advisable to try to reduce your weight in a healthy way combining a healthy diet and regular exercise. No crash diets as this can be too stressful on your body and can deplete your body’s natural stores.

Being overweight can also increase the risk of miscarriage and pregnancy complications such as diabetes, blood clots and high blood pressure. An increased BMI also can make it difficult to assess your ovaries on ultrasound. Infants born to women who are obese are more likely to be large for their age, require neonatal care or have congenital abnormalities.
