How Much Weight Can You Lose with Lap-Band?

The Lap-Band procedure is a popular choice for people who want to lose large amounts of excess weight, even if they’ve been unable to do so with diet and exercise. 

Over time, the Lap-Band started to compete with other more established procedures such as the gastric sleeve and gastric bypass. It gained massive support due to its cost, its reversibility, and its effectiveness.

Recently, though, Lap-Band procedures have taken a bit of a nosedive. Stories have surfaced by women who were unhappy with the results of the Lap-Band and decided to get it removed. Despite this, it still remains a popular option for those who want effective, reversible weight loss surgery

But how much weight can you really lose with the Lap-Band, and is Lap-Band surgery a good option for rapid weight loss?

What Is Lap-Band Surgery?

The adjustable gastric band, often known by the brand name Lap-Band, is a band made of silicone that constricts the stomach in order to reduce the amount of food that can fit in the stomach. This mechanic is similar to procedures such as the gastric bypass or the gastric sleeve.

There’s one big way the Lap-Band differs from the other surgeries. It’s easily reversible: all a patient needs to do is have the surgeon remove the band. Lap-Band removal does not present many risks, and as a result, many bariatric patients choose Lap-Band knowing that if they’re ever unsatisfied, they can have it removed.

Lap-Band is a trademark of Allergan, Inc, and is not a generic name; however, many people have associated all adjustable gastric band procedures with Allergan’s Lap-Band product.

How Much Weight Can You Lose With Lap-Band Surgery?

Lap-Band patients lose, in total, 50% of excess weight. To calculate excess weight, take your current weight and subtract your ideal weight (or weight at a healthy BMI).

For example, if a patient weighs 350 pounds but their ideal weight is 150 pounds, their excess weight is 200 pounds and they can expect to lose 100 pounds with Lap-Band surgery. Their resulting weight is 250 pounds.

Some patients lose far more weight, and others do not have very good results at all. 

What factors affect the potential weight loss after Lap-Band Surgery?

How Certain Factors Affect Lap-Band Weight Loss


Diet & Eating Habits

Bariatric surgeries aim to make it easier for patients to make good eating choices by making it more difficult to make bad ones. A Lap-Band patient who meets their weight loss goals and surpasses the average weight loss generally has excellent eating habits post-op. They commit to the diet prescribed to them by the doctor. They also avoid returning to the old habits that led them to gain weight in the past.

Exercise Regimen

Despite the fact that patients need bed rest immediately after surgery, they will be allowed to introduce exercise later on. Successful patients exercise daily and work in more difficult workouts in order to drive progression.

It’s recommended that patients start exercising 2-4 weeks after surgery.

Adjusting the Band

Adjusting the Lap-Band can affect weight loss results. Some patients may feel great discomfort due to the band and decide to have it loosened to reduce said discomfort. However, the stomach volume ends up larger when the band is adjusted in this way. This allows patients to consume more food.

Is The Lap-Band Surgery Recommended?

In general, we recommend that patients choose gastric bypass or gastric sleeve surgeries instead. They’re not reversible, but they are more effective over longer periods of time. Patients who remove the Lap-Band tend to regain some weight, whereas gastric bypass or gastric sleeve patients tend to keep it off for the long term.
