Complications and Side Effects

Most bariatric surgery patients experience one or more complications or side effects in the weeks following surgery. Common ones include vomiting, nausea and diarrhea. Often, these symptoms are the result of going off of the recommended diet. Nutrient deficiencies can occur during this time if supplements are not taken as prescribed.

Some complications are more serious and require medical attention. Patients should always consult their surgeons when they have medical symptoms.

  • Strictures, or scar tissue at the surgery line blocking swallowing
  • Leaks from the sleeve seam line, the RYGB or BPD-DS seam lines or the lap-band connection tube
  • Recurrent vomiting, which can cause dehydration or a displaced gastric band
  • Obstruction, or blockage of the gastric band leading to inability to swallow
