Bariatric surgery is a keyhole surgery for obesity. Since it ss done by keyholes, patients usually have a 24-48 hour hospital stay and have mild pain that can be controlled with oral pills. Many patients confuse bariatric surgery with liposuction. This is different since in liposuction, only fat beneath the skin is extracted and can lead to weight loss of about 5- 10 kgs from a region. Bariatric surgery on the other hand involves a gastrointestinal surgery that leads to decreased appetite, pronounced weight loss (30% of body weight) and resolution of diabetes, sleep apnoea and arthritis.
