LAP-BAND vs. Gastric Bypass 

LAP-BAND® and gastric bypass surgeries are both designed to facilitate weight loss by reducing the capacity of your stomach, but the procedures have significant fundamental differences. Gastric bypass involves making permanent alterations to your digestive tract. LAP-BAND involves temporarily placing an inflatable device around the top of your stomach. Dr. Jacqueline Osuna, serving Guadalajara and Tijuana, MX, invites you to learn more about LAP-BAND vs. gastric bypass surgery.

The LAP-BAND is fully adjustable following placement, and it can be removed at any time.

Gastric bypass creates a permanent rerouting of the gastrointestinal tract.

The Procedures

During gastric bypass surgery, Dr. Osuna staples the stomach to create a pouch. This smaller section of the stomach is connected to the middle portion of the small intestine. The surgery takes about three hours and typically requires a three-day hospital stay.

Placing a LAP-BAND around the stomach takes about an hour, and patients are usually discharged within a day of their procedure.


Gastric bypass requires a longer recovery than LAP-BAND surgery. LAP-BAND patients are usually able to return to their regular activities after three to four weeks of recovery. A full gastric bypass recovery typically takes between six and eight weeks. LAP-BAND patients will mostly experience soreness along the port site (which allows the LAP-BAND to be adjusted), compared to the discomfort associated with alterations to the digestive system made during gastric bypass.

Post-Surgical Diet

LAP-BAND and gastric bypass surgeries require patients to limit their diet to liquids the first week following the procedure. Patients can then begin having pureed or soft foods for a few weeks, and gradually transition to solid foods. Generally speaking, gastric bypass patients must limit their diet to soft foods for longer than LAP-BAND patients.

There are post-surgical dietary guidelines in place for both gastric bypass and LAP-BAND patients, such as testing one food at a time to ensure it can be tolerated, and avoiding foods that are difficult to digest, such as fibrous vegetables or nuts. Despite following these guidelines, bypass patients are likely to experience dietary and digestive issues. About 80 percent of gastric bypass patients will experience dumping syndrome when they eat the wrong foods.

If you are ready to start a new phase of health in your life, Dr. Osuna is here to help you decide the best way to achieve weight loss.

Additionally, bypass patients need to take more nutrient supplements. They will also need to be more vigilant in monitoring for vitamin or mineral deficiencies, since the procedure reduces the body’s ability to absorb nutrients.

Weight Loss

LAP-BAND and gastric bypass patients can both lose a significant amount of weight quickly and enjoy lasting results. Compared to LAP-BAND, gastric sleeve patients have a tendency to lose weight faster and lose a greater amount of weight.
