Lap Band surgery
Gastric band surgery (commonly referred to as "lap band") is a procedure to help obese patients lose weight. During gastric band surgery, an inflatable band is placed around the top portion of the stomach, creating a small pouch. During meals, food accumulates in this top stomach pouch, causing the stomach to feel full after only a small portion is consumed.
A sleeve gastrectomy (also known as vertical sleeve gastrectomy) is an irreversible surgery to reduce the size of the stomach, thus promoting weight loss by reducing the amount of food you can consume. Unlike gastric bypass, it doesn't alter the digestive tract.
Gastric bypass surgery alters the digestive tract by attaching a small stomach pouch to the small intestine. By bypassing part of the intestine, the number of calories your body can absorb is limited, a benefit not provided by a sleeve gastrectomy or the lap band. Gastric bypass surgery is used to treat severe morbid obesity.
Intragastric balloons are a non-surgical weight loss option for people with a BMI of 30-40. Silicone balloons are placed in the stomach via an endoscopy. It’s then filled with saline, creating a feeling of fullness after even small meals. It remains in the stomach for up to six months, after which it's removed.
