Is Bariatric Surgery Safe?

The safety of bariatric surgery is well established. It is a safe and effective weight loss procedure for morbidly obese people resistant to losing weight.

However, like all surgeries, there are complications and side effects associated with the procedure that your doctor will discuss with you.

Regardless of the type of bariatric procedure, there are common problems that may arise. These include:

  • Development of Acid Reflux Disease
  • Post-prandial Emesis (vomiting after you eat)
  • Stomach Pain
  • Excessive Gas
  • Dehydration
  • Food Intolerance (red meats and sugars)
  • Change in Bowel Habits

More serious complications include:

  • Dumping Syndrome — Caused by sugar and results in lightheadedness, faintness, weakness, sweating, palpitations, nausea, cramps, and possibly vomiting or diarrhea.
  • Bleeding (rare)
  • Bowel Leakage leading to infections (rare)
  • Gastroparesis (paralyzed bowel-rare)

Make sure that you consult your doctor and discuss any concerns in detail before making any decisions.


Because of the potential complications and side effects, we believe there is a another alternative. Before opting for surgery, we recommend you try a weight loss program which is designed specifically to help it’s participants lose a  large amount of weight.  The Gabriel Method was designed specifically for this purpose and has proved to be very effective.

If you have any questions about the safety of bariatric surgery, be sure to discuss this with your doctor. Ask about complications and side effects.
