Fertility and weight
12% of all infertility cases are related to weight issues.
If your body is chronically malnourished or you exercise much more than normal then you may be missing some periods. Normal ovulation and reproductive capacity require at least 22% body fat.
On the other hand, being overweight can change the balance of hormones and prevent ovulation.
The good news is that once weight is corrected, the fertility problems associated with it are corrected as well. More than 70% of women conceive as soon as they reach a healthy weight. Doctors consider an ideal Body Mass Index (BMI *) between 19 and 25.
Weight does not only affect fertility, but also pregnancy. According to the March of Dimes Non-Profit Organization, overweight women who become pregnant are at greater risk for developing hypertension and diabetes, while underweight women are more likely to give birth to an underweight baby.
* BMI = weight in kilograms divided by the square of height in meters.
Suppose a woman weighs 60 kilos and is 1.65 meters tall.
We square the height: 1.65 * 1.65 = 2.7225
Then, we divide the kilograms by the square of the height we just calculated: 60 / 2.7225 = 22.04.
