Hi, my wife, 32 years old, and height is 165 cm, has gained weight post pregnancy (c-section) about 4 years back. Not able lose weight at all even after doing regular exercise and following proper diet. She regularly do all home related works and exercise daily, but these things are not able to reduce the weight at all. Her weight is almost constant to 75 kg from last 4 years which used to be 60 kg earlier. She does not have any other health issue. Please suggest what shall we do? Is this a harmonal issue or something else?
