How Soon Will I Lose Weight After Gastric Bypass

Gastric Bypass has helped millions of morbidly obese people lose weight and live a healthier lifestyle. However, many people question exactly how much weight they’ll lose after having surgery and what they need to do to lose as much weight as possible.

Gastric Bypass patients lose weight rapidly in the first 12-24 months after surgery. The rapid weight loss is due to a variety of factors, including:

  • losing weight after bariatric surgeryYour stomach size (pouch) is small, it holds about 1 ounce of food. Therefore, you eat less.
  • Follow dietary guidelines, after surgery you are on a liquid diet then progress weekly to pureed, soft foods and then solid foods as directed by your doctor.
  • Your appetite changes.
  • You absorb less. The food you eat travels from your stomach pouch into a new opening and into your small intestine.

What’s the common recovery for weight loss after surgery?

Here’s a breakdown in what’s common for weight loss after surgery:

  • Six months post-op. Most patients have lost on average 52 percent of their excess body weight at this point.
  • Nine months post-op. The nine month mark depends on your weight loss at the six-month check in. If you lost a significant amount of weight at the six-month mark, your doctor will set a reasonable goal to hit, such as an extra two to five percent of your weight.
  • One year after surgery. At this point, most patients have lost about 65 to 70 percent percent of their excess body weight depending on their starting weight.

While the rapid weight loss after surgery is exciting, weight loss will slow down after year two or three. Remember it is very important to follow the exercise and eating guidelines that your dietitian and doctor have given you.
