Bariatric surgery risks and complications


The risks associated with weight loss surgery are similar to those of any abdominal surgery. Overall, weight loss surgery is very safe, with 80 to 90 percent of patients having no post-operative complications. However it is important to understand that complications can occur. Below is a list of bariatric surgery complications listed by procedure and their percentage of likelihood.

Because of the nature of bariatric surgeries, you may experience side effects as your body adjusts to the weight loss and changes in your eating habits. It's important to discuss these with your bariatric surgeon during your pre-operative appointment so you understand what they mean for you.
  • Chronic nutritional problems
  • Protein deficiency
  • Vitamin and mineral deficiency
  • Transient hair loss
  • Muscle mass loss
  • Nausea/vomiting
  • Dumping syndrome
  • Red meat intolerance
