The risks associated with gastric sleeve surgery are uncommon, but do exist. For example, difficulty swallowing may occur only temporarily due to having a narrow digestive tube.

However, it’s usually resolved between 1 to 3 months after gastric sleeve surgery. Gastro esophageal reflux is a minor complication and resolves with antacid medicine. It’s important to know if you had Gastro esophageal reflux or hiatal hernia prior to gastric sleeve surgery.

Other less common risks are: leakage of the staple line (occurs in less than 2%), bleeding (occurs in less than 3%) and stenosis (occurs in less than 1%).
