Weight Loss Expectations

Patients often hear that having weight loss surgery will cause them to lose about 100 pounds and that's really not true. That's a generic number that's often thrown around. The reality is: each one of these operations results in a specific amount of weight loss and that weight loss really is a percentage of how much overweight that patient is. So if a patient is 100 pounds overweight, we might expect them to lose anywhere from 60-70% (or 60 to 70 pounds) for a given operation. The weight loss that a patient experiences after surgery usually peaks at somewhere about a year to a year and a half after surgery. There are some patients that might lose the weight very rapidly and lose all their weight in 6 months, whereas other patients may take an entire year and a half to lose all over their weight. In the end, it really doesn't matter how quickly you lose the weight, it's just important that ultimately you lose the amount of weight that we expect to lose.
