Weight Loss Surgery At Palmdale Regional Medical Center


Weight-Loss Surgery Options

Palmdale Regional Medical Center offers three minimally invasive surgical weight-loss options: adjustable gastric banding, laparoscopic gastric bypass and laparoscopic sleeve gastrectromy. It is important that patients understand that no one procedure is the best choice for all cases. Each patient is assessed as an individual, with consideration given to their medical history, current medical conditions and other factors. In addition, long-term success with any of the procedures depends on the patient’s adaptation to a healthier lifestyle, including smaller portions of healthy food, daily exercise, supplementation and ongoing support.

Gastric Band weight loss surgery at Palmdale Regional 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. This procedure helps patients lose weight by limiting the amount of food their stomachs can hold using an adjustable band. Most patients can expect to lose 55 to 60 percent of their excess body weight over 18 months. With weight reduction, patients may also see an improvement in obesity-related medical conditions such as diabetes or sleep apnea. In some cases, the surgeon may even remove the band once the patient's target weight is reached.              

With this procedure, there is no effect on the absorption of nutrients. The restrictive capacity of the band may be adjusted by injecting or withdrawing fluid through the port. The success of this device depends greatly on good patient compliance and maintenance. Potential complications include Lap-Band slippage, erosion and failure of the device.

gastric bypass weight loss surgery Palmdale Regional 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. Most patients can expect to reduce their excess body weight by 80 to 85 percent over 18 months.              

Medical conditions such as diabetes, hypertension, hyperlipidemia and sleep apnea are often dramatically improved. Patients who have this procedure may experience negative effects if they eat too many simple sugars, fats or overly processed foods. The contour of the body may change and patients may choose to have plastic surgery after their weight loss. Hair loss may occur during the first three to six months, however this usually resolves within one year. There is a one percent risk of ulcer formation in the pouch, especially if the patient takes NSAIDs (non-steroidal anti-inflammatory drugs such as aspirin or ibuprofen) or smokes. The risk of iron deficiency in menstruating women is possible.

gastric sleeve weight loss surgery Palmdale Regional Laparoscopic sleeve gastrectomy
Laparoscopic sleeve gastrectomy has proven to be a very successful minimally invasive procedure in which 70 to 80 percent of the stomach is removed. This reduces hunger and increases satiety with smaller portions of food. Patients may expect an excess body weight loss of 70 percent. There is less than one percent chance of leakage within the first 30 days. The advantage of a gastric sleeve over gastric banding surgey is that there is no foreign body implanted, and unlike gastric bypass, there is less change in the absorptive capacity of nutrients. The sleeve offers dramatic improvements in health, often including diabetes and hypertension resolution.               

Individual results may vary. There are risks associated with any surgical procedure. Talk with your doctor about these risks to find out if bariatric surgery is right for you.
