Medical institutions have long studied the health benefits of a normal weight and reported that overweight people are more likely to develop diseases such as diabetes, heart disease, high blood pressure and cancer. Weight gain during pregnancy increases the risk of complications in women. People who are underweight or overweight, both men and women, suffer more from the problem of infertility. Often this problem is due to hormonal problems due to too much or too little body weight.
If you have fertility problems, you can get pregnant with IVF treatment. Some recent studies have shed some light on the effect of weight on fertility and IVF success.
