Thank you for the question. After the tummy tuck surgery many patients report that they feel “full” with smaller amounts of food intake. This may be related to the abdominal muscle repair and Increased pressure on intra-abdominal organs including the stomach. This feeling of “early satiety” results with time (several months). Stomach size itself is not altered with the tummy tuck surgery. I hope this helps.
Most women who have a tummy tuck feel "full" afterward, which results in about a 10-pound weight loss, but this is temporary. This is a result of tightening of the muscle, which increases the pressure on the stomach area. Try to maintain a diet and exercise program after surgery to help sustain your great result. Best wishes!
