Weight loss surgery is considered successful when 50% of excess weight is lost and the loss is sustained up to five years. For example, a patient who is 100 pounds overweight should lose at least 50 pounds; a patient who is 200 pounds overweight should lose at least 100 pounds. And they should be able to maintain loss successfully for the following five years. Ninety-five percent of patients reach that goal after gastric bypass surgery.

Successful surgery enables you to lose at least 50 percent of your excess weight. Few people lose all their excess weight, but nearly all gain numerous important health benefits. But it's important to remember that there are no guarantees with any method of weight loss, even surgery. Success hinges on your ability to become part of the plan to support the surgical tool you've chosen and make lifestyle changes with exercise and dietary adjustments.

Candidates for surgery are usually at least 100 pounds over their ideal body weight. Another measure of obesity is the body mass index (BMI) The body mass index is your height in kilograms divided by the square of your height in meters. There are several web sites that have body mass calculators. Generally a body mass of 40 or higher qualifies for surgery, or over 35 with certain health problems called co-morbidities.

Most patients lose weight rapidly for 18 to 24 months after surgery. Some patients may then regain some of their lost weight, although few will regain it all. Surgery also improves most obesity related health problems, such as diabetes.

There are several different kinds of surgical procedures to help people who are significantly overweight. By reducing the size of the stomach, these procedures restrict the amount of food you can consume. Long-term success depends in large part on permanently following a restricted diet and making major lifestyle changes.

Gastric Bypass surgery or stomach stapling usually requires a 2-4 day hospital stay and 3-6 weeks recovery time depending upon the type of work you do. The cost of bariatric operations can usually range from $17,000 to $25,000 and although many patients have had to fight for coverage, more insurers are beginning to pay, recognizing that the surgery can save them money in the long run. If Lap band surgery is performed laparoscopically, patients typically spend less than 24 hours in the hospital.

This really depends on the type of weight loss surgery you have and the type of job you do. For lap band surgery the procedures are usually done laparoscopically and don't require stapling or rearranging of your stomach anatomy, thus your hospitalization is usually less than 24 hours. And your recovery can be as little as a few days. For gastric bypass surgery, most patients can proceed with a regular activities after 6 weeks.

The lap band procedure is reversible and does not modify your internal anatomy. Stomach stapling is designed to be permanent, but in general gastric bypass procedures are reversible. But ask your doctor about your specific procedure.

A weight loss of more than 50 grams makes sensor restoration difficult, and beyond 100 grams, it is virtually impossible. Weight loss is affected by ambient humidity, flow rate, and in certain cases, the type of sensor being used. The sensors work best, and last longer, if they are kept moist. If your sensor is losing more than 50 grams of water per month, add water every two weeks. Please refer to the detailed information provided in our Interfering Gas Data tables.

A3. Patients undergo a thorough screening process at the Weight loss institute of Arizona to identify whether they are appropriate candidates for surgery. Surgical candidates need to be at least 100 pounds overweight. A more accurate measurement is the Body Mass Index or BMI. Surgical candidates need to have a BMI above 30 or a BMI above 30 with other obesity-related conditions such as heart disease and diabetes.

You will want to obtain a copy of your current insurance policy to determine if these procedures are covered. Insurance details can be difficult to navigate, and our insurance specialists will gladly assist you in determining if these procedures are a covered benefit in your plan.

If you're lucky, the weight loss institution you choose will handle insurance matters for you. In any event, you might be surprised to learn that many insurance companies will cover the treatment of health problems caused by obesity but not obesity itself. So it is a good idea to have a basic understanding of what your insurance will cover prior to setting up a meeting with a bariatric surgeon.

Your personal surgical history and the technique to be used are discussed at your surgical consultation.

The short answer is no. Surgery is not a solution for everyone. We only determine whether a patient is right for surgery after a complete evaluation and discussion with the patient. Because weight loss surgery is a life-altering procedure, we want to make sure our patients are committed to making the lifestyle changes needed for a successful procedure.

The two most common operations are adjustable gastric banding and gastric bypass. With both procedures, the size of the area in stomach where food collects is reduced. The adjustable gastric band is less invasive than gastric bypass and is often done laparoscopically. By placing an adjustable band around the stomach the surgeon creates an upper pouch.

It is very important that you do not get pregnant for at least two years after any type of weight loss procedure. You must use two reliable methods of birth control throughout this time period. Once your weight has stabilized and the appropriate months have passes, you can become pregnant. It is important, however, to be monitored closely by an obstetrician and nutrition expert familiar with your weight loss surgery.

Surgery for weight loss is a decision between a doctor and a patient. People who do have surgery or who have had weight reduction surgery should be aware of two things. First, there are at least ten different types of surgery for weight loss. Each effects how the body gets the nutrients it needs. For example, people who have undergone Roux-en-Y surgery generally require certain nutrients in supplemental doses for the rest of their life.

Weight loss surgery is for patients who are morbidly obese (100 lbs above their ideal body weight) with a BMI of >40, or > 35 with co-morbidities.

Weight-loss surgery alters the body's digestive process by limiting the amount of food the stomach can hold and/or by limiting the absorption of nutrients. The most common procedures are restrictive, malabsorptive or a combination of both procedures. Restrictive procedures reduce the amount of food the stomach can hold, but don't interfere with the body's normal digestion of food and nutrients.
