Obesity is the excess accumulation of body fat. It results from high-calorie intake and poses a significant risk of developing many life-threatening diseases. Obesity surgery is usually considered as the best treatment option for patients who have failed to respond to non-surgical weight loss strategies like diet, medication and exercises. Obesity surgery promotes weight loss by decreasing the amount of food your stomach can hold and limiting absorption of nutrients.
Common bariatric (obesity) operations include:
Laparoscopic Adjustable Gastric Banding
The procedure involves placing an inflatable band around the upper part of the stomach to create a small pouch. This reduces the amount of food you can eat, making you feel full with only a small amount.
Laparoscopic Sleeve Gastrectomy
This procedure involves removing approximately 75% of the stomach by turning it into a narrow tube or sleeve. This reduces the size of the stomach and limits the amount of food intake.
Laparoscopic Gastric Bypass
This procedure involves stapling off a large section of the stomach which leaves behind a small pouch that can accommodate only about half a cup of food at a time. A section of the small bowel is attached to this newly formed pouch allowing the food to bypass the lower stomach and much of the small intestine, leading to weight loss.
