Hence, ovulation may not happen at all. Even low weight can cause infertility. It leads to decrease in the production of the hormone GnRh which is essential for regular ovulation. This affects the development of uterine lining and its possibility of embedding the eggs in the embryo.

Gestational Diabetes

There is a high risk of your having gestational diabetes during pregnancy if you happen to be overweight.

"This is so because excessive weight increases insulin resistance and this prevents your body from effectively using the insulin that is being produced," explains Dr. Soni.
