How much weight can I lose with Roux-en-Y gastric bypass?
On average, patients can usually expect to lose 30 lbs. within a month, 60 lbs. in six months and 100 lbs. in a year. Patients who exercise after surgery, as recommended, will experience better weight loss. People who are super-morbidly obese tend to lose weight at a faster rate. Men usually lose weight more quickly than women do, as they have more muscle mass and muscle burns calories more quickly.
