Which is the most effective: lap band, gastric bypass or gastric sleeve?

You are: It isn't the surgery that is effective, it is the patient. While the bypass will lose most weight in the first year, followed by the sleeve, then the band- it is an average. What counts most is how you use the tool - i've had patients lose all their weight in a year with all of these operations, and patients who have lost none. The key- change your eating habits, healthy food, small portions.

Operations: In terms of ultimate weight loss, the bypass would be #1 followed closely by sleeve. The band would be a distant third. For fixing problems like diabetes, high blood pressure, high cholesterol, sleep apnea, the ranking is the same. Sleeves are a good option for someone without diabetes or heartburn. If you have those problems or have a bmi over 50, the bypass is a better option.
