Surgery to promote weight loss is a drastic measure. It is a permanent procedure, and to be successful, it requires a lifetime commitment to changes in how and what you eat. Weight-loss surgery, also called bariatric surgery, is for people who are severely overweight and cannot lose weight by traditional means or who suffer from serious, life-threatening, weight-related health problems. If you fit this profile and are determined to lose weight to improve your health, surgery may be the answer. Your health care provider will weigh the risks and benefits to determine whether the risk of NOT having the surgery outweighs the potential complications from having the surgery.
You may be a candidate for weight-loss surgery if you meet these criteria:
You have tried and failed with dieting, exercise, and lifestyle changes.
Your Body Mass Index (BMI) is 40 or greater, or your BMI is between 35 and 40 and you have a life-threatening, weight-related health problem such as diabetes, severe sleep apnea, or heart disease.
You are more than 100 pounds over ideal weight.
How It Works :
There are two main categories of surgery that promote weight loss. Restrictive procedures, which include gastric banding, gastric bypass, and vertical banded gastroplasty, limit the amount of food the stomach can hold by closing off or removing parts of the stomach. This type of surgery does not interfere with the normal digestive process; it prevents you from eating large amounts of food at one time.
Malabsorptive procedures, such as the biliopancreatic diversion and the Roux-en-Y gastric bypass (RGB), limit the calories and the amount of nutrients that can be absorbed by the intestine in addition to reducing the size of the stomach. In the RGB procedure, a surgeon first creates a small stomach pouch, then makes a direct connection from the pouch to a lower segment of the small intestine, bypassing large portions of the digestive tract that absorb calories and nutrients.
Depending on your weight and medical history, your surgeon may be able to use laparoscopic technology. Instead of making a large incision, a surgeon using laparoscopic techniques makes one or more small incisions through which slender surgical instruments are passed. A laparoscopic procedure usually reduces the length of the hospital stay, diminishes discomfort, limits surgical scarring, and shortens recovery time.
Benefits vs. Risks :
Weight-loss surgery is a serious undertaking. You'll need to clearly understand what the surgery involves and the potential benefits and risks before you make your decision. As with any surgery, there are some risks, but for many people the health risks of remaining at their current weight are greater than the risks of surgery.
Benefits: Most people lose weight fairly rapidly in the first few weeks after surgery and continue to lose for 18 to 24 months afterward. Regaining some weight is common, but most people maintain a long-term weight loss of around 100 pounds or more. Weight-related health conditions, including diabetes, heart disease, joint problems, and sleep apnea, often improve dramatically with weight loss. Emotional benefits may include a better self-image, higher self-esteem, and the reversal of depression.
Risks: Risks of any surgery can include bleeding, infections, bowel obstruction, and respiratory problems. Follow-up surgery to correct complications is necessary in about 10 to 20 percent of people who have weight-loss surgery. In addition, some people develop gallstones after surgery as well as nutritional deficiencies such as anemia, osteoporosis, and metabolic bone disease. These deficiencies can usually be avoided if you get enough vitamins and minerals from a combination of food and supplements.
