Bariatric Surgery is an umbrella term for the various forms of surgeries falling under it. Here is a glimpse for a detailed understanding.
Gastric balloon is an endoscopic procedure which is done under short anaesthesia or sedation. In this , a silicon balloon is placed in stomach through mouth & inflated with 500 ml saline. This occupies ~50% of space within the stomach & thus person eats a smaller meal & may lose 10 kg – 30 kgs in 6-12 months. This is relevant in extremely high risk individuals to reduce surgical risk, to avoid surgery and in people who are looking for smaller weight loss.
