Hello, I am Dr Himali Tecani, I am a consultant obstetrician and gynecologist at Manipal hospitals, Old Airport Road, Bangalore. At delivery, a woman loses about 5 to 6 kgs of weight, this is the weight of the baby and the after births. Now in the next 2 weeks after that, the woman loses the fluid retained during pregnancy, which is about 2 to 3 kgs in the form of diuresis. Normal blood loss also adds to losing the weight. Now at the end of 6 weeks, most women lose about half of the weight gained during pregnancy. A well-balanced diet and adequate hydration, along with exercises, would help to lose the weight. Also during breastfeeding, a woman requires 500 calories extra per day, but breastfeeding also helps your body burn the calories. And hence diet with hydration and exercise would help lose weight. Most women lose all the weight gained during pregnancy in about 6 to 12 months.
