Gastric bypass surgery is the most common type of weight-loss surgery performed in this country, with approximately 130,000 Americans undergoing the procedure every year. The surgery consists of two procedures that are performed at the same time. During the first part, sometimes called “stomach stapling,” Dr. Billy creates a small stomach pouch that restricts the amount of food that can be held at one time, which causes patients to feel full sooner, eat less and lose weight. The second part of the surgery involves creating a “bypass” of part of the small intestine so that fewer calories are absorbed during digestion.
Patients’ suitability is evaluated on an individual basis. In general, though, gastric bypass surgery is reserved for individuals who have a body mass index (BMI) that is greater than 40, and who have previously been unsuccessful in losing weight through diet and exercise. Sometimes patients with a lower BMI — between 35 to 39.9 — who have serious, weight-related health concerns, like type 2 diabetes, high blood pressure or severe obstructive sleep apnea (OSA), may also be considered viable candidates.
Every patient is different, but it is possible to lose half to two-thirds of your body weight within two years of surgery. Most patients maintain the majority of their weight loss long-term. To achieve permanent results requires committing to new, healthy lifestyle. These changes, include following a balanced diet and regular exercise. Ventura Advanced Surgical Associates offers all patients an eight-week Lifestyle Wellness Program following gastric bypass surgery for optimum and on-going success.
Along with weight loss, gastric bypass surgery can resolve or improve other weight-related health conditions, such as:
