Patients typically need a Body Mass Index (BMI) of 35 or higher, with obesity-related health conditions, or a BMI of 40 or more to qualify for gastric sleeve surgery.

The intragastric balloon is a non-surgical weight-loss method where a balloon is inserted into the stomach to reduce its capacity temporarily. While it can be an effective weight-loss tool, patients may experience side effects like nausea, vomiting, abdominal discomfort, acid reflux, and, in rare cases, balloon deflation or migration. Most side effects occur in the first few days after the procedure and can be managed with medication.
