An adult is considered "overweight" when he/she is above a healthy weight, which varies according to a person's height. An individual is overweight when their BMI is between 25–29.9. The standard used by researchers to define a person's weight according to their height is "body mass index" (BMI).
An adult with a BMI of 30 or more is considered obese. For example, for a 5'4" woman, this means that she is 30 or more pounds over her healthy weight. If your BMI = 35.0 - 40 you are severely obese (with risk factors morbidly). If your BMI = 40.0 and up you are morbidly obese.
- body mass index (BMI)
- waist circumference
- risk factors for diseases and conditions associated with obesity
The BMI is a measure of your weight relative to your height and waist circumference measures abdominal fat. Combining your BMI and your waist circumference with information about your additional risk factors yields your risk for developing obesity-associated diseases and determines whether you are a candidate for weight loss surgeries such as gastric bypass surgery, the gastric band or other weight loss procedures. So your BMI is a good number to start with in identifying your risk due to your weight. To find out what your BMI is click here.
Gastric Bypass surgery has been performed on patients as young as 16 years of age. In this age group, the concern is that the patient make the decision for surgery him- or her-self, and that there be a full understanding and commitment to the life long altered eating pattern which will be necessary for success.
Patients over 65 require very strong indications for surgery, and must also meet MediCARE criteria, which are stringent. The risk of surgery in this age group is increased, and the benefits, in terms of reduced risk of mortality, are reduced. In many instances, this argues against the surgery.
Common tests include:
- Complete Blood Count (CBC)
- Urinalysis, and a Chemistry Panel, which gives us a readout of about 20 blood chemistry values
- Glucose Tolerance Test to evaluate for diabetes, which is very common in overweight persons, and frequently is undiagnosed
- Most persons, except the very young, get a Chest X-Ray and an Electrocardiogram
- pelvic ultrasound (women only), to look for abnormalities of the ovaries or uterus
- abdominal and gallbladder ultrasound (everybody) to look for gallstones
- psychiatric evaluation (usually required by your insurance)
Other tests which are frequently ordered when indicated include:
- Pulmonary Function Testing
- Sleep Studies
- GI Evaluation
- Cardiology Evaluation
Primarily, your surgeon needs an accurate assessment of your health, before undertaking a big operation. The best way to treat a complication is to never have it in the first place, due to advance knowledge.
Your surgeon wants to know if your thyroid function is adequate (hypothyroidism can lead to sudden death post-operatively), if you are diabetic (we will have to take special steps to control your blood sugar), if your heart is sound (surgery increases cardiac stress). Your doctor will look for signs of liver malfunction, breathing difficulties, excess fluid in the tissues, abnormalities of the salts and minerals in body fluids, and abnormal blood fat levels.
Patients who have significant gastrointestinal (GI) symptoms such as upper abdominal pain, heartburn, belching sour fluid, may have serious underlying problems, such as a hiatus hernia, gastroesophageal reflux, or a peptic ulcer. For example, many patients have symptoms of reflux, and we know that up to 15% of such persons may have early changes in the lining of the esophagus which could predispose to cancer. It is important to identify these changes, so that a suitable surveillance program can be planned for the future.
When our doctors detect GI symptoms on your preliminary evaluation, we ask that you have an evaluation before surgery, so that your surgeon can take care of them at the same time, and avoid complicating surprises at surgery.
The sleep study detects a tendency for abnormal cessation of breathing, usually associated with airway obstruction when the muscles relax during sleep. This condition is associated with a high mortality rate, just during ordinary living. After surgery, you will be sedated, and will be receiving narcotics for pain, which also depress normal breathing drive, and reflexes. At that time, airway obstruction becomes even more dangerous, and we need to have a clear picture of what to expect, and how to handle it.
Your doctors office ordinarily can schedule surgery within about 2 - 3 weeks, once financial arrangements are made. Insurance approval is a pre-requisite for many persons. When your doctors office obtains approval, you are contacted to determine if, and when, you wish to schedule surgery. From that time, surgery can be done in 2 - 3 weeks, or at your convenience (it is recommend that you do not wait more than about 90 days, or re-approval may be needed).
Even though your insurance may cover bariatric surgery, they will make you jump through a lot of hoops prior to granting approval. They can require a medically supervised weight loss plan which is usually 6-12 months in duration. They usually require medical proof of comorbidities along with a letter of medical necessity. Once this all has been completed and submitted to the insurance company, the time it takes to get an answer can vary, from about 4-8 weeks, to as long as they can dawdle without being asked. Our insurance analysts try to follow-up regularly on approval requests, and each telephone call can consume from several minutes to multiple hours of frustrating waiting, just to get through. Try calling the claims service of your insurance company yourself, about a week after your letter is submitted, and ask them what the status of your request is – our insurance analysts do that all day long.
We are trying to speed up our process, and have added several new analysts in our office. It really does help, when you get behind the process and call your carrier regularly to inquire.
Coverage may be denied because there is a specific exclusion in your policy for obesity surgery, or "treatment of obesity", which is manifestation of the attitude of our society toward obesity, and the discrimination which obese persons suffer. Such an exclusion can often be attacked, by the reasoning that the surgical treatment is recommended as the best therapy for the co-morbidities, which usually are covered.
Coverage may also be denied for lack of "medical necessity". A therapy is deemed to be medically necessary when it is needed to treat a serious or life-threatening condition. In the case of Morbid Obesity, alternative treatments are considered to exist – according to conventional wisdom – such as dieting, exercise, behavior modification, and some medications. Usually, medical necessity denials hinge on the insurance company’s demand for some form of documentation, such as 1 to 5 years of physician-supervised dieting or a psychiatric evaluation. The best approach to these demands is to try to produce reasonable information. Once you have successfully jumped over all the obstacles, it is more difficult for you to be denied.
First, help us to get all the information (diet records, medical records, medical tests) together in your case, so the carrier cannot deny for failure to provide "necessary" information. Letters from your personal physician and consultants, attesting to the "medical necessity" of treatment, are particularly valuable – when one or several physicians corroborate the necessity of treatment, it will be hard for the carrier to contradict them.
When the letter is submitted, call your carrier regularly (about once a week), to ask about your status. You may also be able to protest unreasonable delays through your employer or human relations/personnel office.
If you do not have insurance, don't give up! You still may have an option available in obtaining treatment. Simply become a cash patient. Pay for the surgery your self. Some doctors can work with you on their pricing or payment plans. The benefit of paying for the surgery your self is that you don't have to wait for insurance approval and can usually have the surgery within 1-2 weeks of seeing the surgeon.
No. Laparoscopic operations carry the same risk as the similar procedure, performed as an open operation. The benefits of laparoscopy are typically, less discomfort, shorter hospital stay, earlier return to work, and much reduced scarring.
Typically, the gastric bypass or the gastric banding requires a total time in the operating room of 2 - 3 hours – the operation itself takes 1½ to 2½ hours. If your family will be waiting, they should understand that the operation may not begin immediately, so they should not watch the clock. If the operation is lasting longer, the doctor may be able to send word.
Your surgeon will try very hard to control pain after surgery, to make it possible for you to move about quickly, and become active, which helps avoid problems and speeds recovery. Typically several drugs are used together, and a system called Patient Controlled Analgesia (PCA), which allows you to give yourself a dose of pain medicine on demand, whenever you need it. Most patients are pleasantly surprised at how little discomfort they experience.
As long as it takes to be self-sufficient. Typically, the hospital stay (including the day of surgery) is 1 day for a Laparoscopic Band, 2 days for a Laparoscopic Gastric Bypass, and 3 days for an Open Gastric Bypass.
Most patients will have a small tube to allow drainage of any accumulated fluids from the abdomen. This is a safety measure, and can be removed a few days after the surgery. It produces no more than minor discomfort.
Your surgeon will recommend that you do not drive until you have stopped taking narcotic medications, and can move quickly and alertly to stop your car, especially in an emergency. This is for your own safety, and that of others on the road. Usually this takes 7 -14 days after surgery.
Life After Surgery
Many centers advise against this. But they will not harm you, or your operation. Many patients do find carbonated beverages uncomfortable, from the gas they produce.
It is recommend that you avoid any flavored drinks between meals, such as diet soda, coffee and tea – use of these tends to activate your hunger mechanism.
Dumping syndrome is caused by eating sugars, or other foods which contain many small particles, on an empty stomach. These substances produce a high osmotic load. Your body handles these by diluting the food particles with water, which reduces blood volume, and causes a shock-like state. Sugar may also induce insulin shock, due to the altered physiology of your intestinal tract. The result is a very unpleasant feeling, as you break out in a cold clammy sweat, turn pale white, feel butterflies in your stomach and a pounding pulse. This may be followed by cramps and diarrhea. This state can last for 30 - 60 minutes, and is quite uncomfortable – most have to lie down until it goes away. It can be avoided by not eating the foods which cause it, especially on an empty stomach. A small amount of sweet, such as fruit, is well-tolerated at the end of a meal.
Milk contains a special sugar, called lactose, or milk sugar, which is not well digested. This sugar passes through undigested, until bacteria in the lower bowel act on it, producing irritating byproducts, as well as gas. Depending on individual tolerance, some persons find even the smallest amount of milk or milk sugar will cause cramps, gas and diarrhea.
The basic rules are simple, and easy to follow:
- Eat 2 -3 meals per day, no more. Protein, in the form of lean meats (chicken, turkey, fish), and other low-fat sources, should be eaten first, and should comprise at least half the volume of the meal eaten. Foods should be cooked without fat, seasoned to taste. Avoid sauces, gravies, butter, margarine, mayonnaise, and junk foods.
- Never eat between meals - nothing. Do not drink flavored beverages, even diet soda, between meals.
- Drink 2 -3 quarts, or more, of water each day. Water must be consumed slowly, 1 -2 mouthfuls at a time, due to the restrictive effect of the operation.
- Exercise aerobically every day, for 20 minutes at least (one mile brisk walk, bike riding, stair climbing, etc.). We encourage weight/resistance exercise 3 - 4 days per week.
Snacking is the worst thing you can do to your weight control process. Snacking, nibbling or grazing on foods, usually high-calorie and high-fat foods, can add hundreds of calories a day to your intake, while defeating the restrictive effect of your operation. Since most snacking is done out of impulse, hunger-limitation or satiety has a limited effect in preventing it. Snacking will definitely slow down your weight loss, and can lead to late regain of weight (usually not all of it, unless you get really ridiculous). Snacking is also a habit, which is easier to avoid, than to stop once it is started.
If you start snacking after a while, and notice the bad effects, your surgeon will help you to stop. It’s a lot easier, and more rewarding, never to start.
When you are losing weight, there is a heavy load of waste products to eliminate, mostly in the urine. Some of these substances tend to form crystals, which can cause kidney stones. A high water intake protects you, and helps your body to rid itself of waste products efficiently, promoting better weight loss.
Water will also fill your stomach, and will help to prolong and intensify your sense of satisfaction with food. If you feel a desire to eat between meals, it is because you did not drink enough water in the hour before.
When you have a Gastric Bypass, you lose weight because the amount of food energy (calories) which you are able to eat is much less than your body needs to operate. It has to make up the difference by burning reserves, or unused tissues. Your body will burn any unused muscle first, before it begins to burn the precious fat it has saved up. If you do not exercise daily, your body will consume your unused muscle, and you will lose muscle mass and strength. Daily aerobic exercise for 20 minutes will communicate to your body that you want to use your muscles, and force it to burn the fat instead.
The idea of having an operation is to become slender and healthy, not skinny and weak. If you lose most of your excess fat, and retain most of your muscles, imagine how much power and energy you will have, to enjoy your new life!
