Adjustable Gastric Banding
Laparoscopic adjustable gastric banding surgery (LAP-BAND®) is the least invasive bariatric procedure and does not require the surgeon to cut or reattach any part of the stomach or small intestine.
Laparoscopic Gastric Bypass
Laparoscopic gastric bypass is a minimally invasive procedure in which a one-ounce stomach pouch is created and attached to the small intestine. This restricts patients to eating smaller portions of food, increasing satiety and reducing absorption.
Laparoscopic Sleeve Gastrectomy
During a laparoscopic sleeve gastrectomy there is no foreign body implanted, and there is less change in the absorptive capacity of nutrients. The sleeve offers dramatic improvements in health, often including diabetes and hypertension resolution.

Frequently Asked Questions
- How Do I Know if I Am A Candidate for Weight-Loss Surgery?
Candidates for weight-loss surgery must meet certain BMI requirements or be at high-risk for certain health factors.
- What’s the difference between the three kinds of weight-loss surgery?
In a gastric bypass, the top portion of the stomach is stapled to create a small pouch, which is connected to the small intestine. This reduces the amount of food eaten as well as absorption of calories. The gastric sleeve permanently removes 70 to 85 percent of the stomach, reducing hunger. In adjustable gastric banding (LAP-BAND®), an inflatable band is placed around the upper part of the stomach. The new, smaller pouch limits stomach capacity and increases the feeling of fullness.
- How much weight can you expect to lose?
Gastric bypass is associated with the most weight loss, usually 80 to 85 percent of excess pounds. Sleeve surgery can shed about 75 percent of excess weight and LAP-BAND® offers 55 to 60 percent.
- Which kind of weight-loss surgery works best?
The type of surgery has to be matched to the patient, based on his or her lifestyle and medical conditions.
- Does the surgery keep weight off permanently?
It’s important to remember that weight-loss surgery involves more than an operation. Patients have to take a holistic approach that includes diet and exercise.
- Will My Insurance Cover Weight-Loss Surgery?
Palmdale Regional works with most major insurance providers. Talk to your insurance company or contact us to find out more.
- What About Life After Surgery?
Maintaining your weight after surgery is key. Support groups, educational opportunities and a strict diet will help you keep the weight off and live a healthier life.
