The Basics of Gastric Bypass Procedures
Bariatrics is the general term applied to the medical treatment of obesity. Obesity has become a worldwide problem and more and more people are seeking treatment. Bariatrics encompasses pharmaceutics to treat obesity as well as surgeries such as Gastric Bypass surgery or Lap-Band surgery. Bariatic treatments that reduce obesity help eliminate obesity-related health problems such as sleep apnea, diabetics and heart problems.
Candidates for this procedure:
You qualify for bariatric surgery if:
   You are overweight by 100 pounds or more
   You have a Body Mass Index (BMI) of more than 40 or
   You have a BMI of more than 35 with illnesses related to being overweight
   You have been overweight for five years or more
   You have failed to lose weight or sustain weight loss under supervision
   You are willing to comply with the lifestyle and diet changes required after this surgery

What does my Body Mass Index number mean?
The BMI is a measure of body fat based on height and weight.  Your BMI will fall within the following four categories:

   Underweight = BMI of less than 18.5
   Normal weight = BMI between 18.5 and 24.9
   Overweight = BMI between 25 and 29.9
   Obesity = BMI of 30 or greater

Symptoms of obesity:
Obesity can cause a number of health problems, many of which can improve or even disappear after gastric bypass surgery or gastric banding surgery. Some common symptoms are heart disease, high blood pressure, diabetes, asthma, sleep apnea, high cholesterol, respiratory insufficiency, heartburn, and arthritis of weight-bearing joints.
Gastric Bypass Surgery
Gastric bypass surgery refers to any of a group of similar operations undertaken to help severely obese people lose weight. This weight loss procedure targets morbid obesity, or accumulated excess weight in the form of fatty tissue, and the specific health problems it causes.

There are generally three types of weight loss procedures. Restrictive procedures, such as lap-band surgery, reduce the amount the stomach can hold, while malabsorptive procedures shorten the digestive tract. The 3rd type of weight loss surgery combines both weight loss techniques.

Gastric bypass combines restrictive and malabsorptive procedures which have been performed worldwide for over 35 years.

The procedure for this weight loss surgery involves two major steps. First, the surgeon creates a small stomach pouch which will help curb food intake. The 2nd step is to attach a Y-shaped section of the small intestine into the pouch so that food will bypass the lower stomach, the intestine’s 1st segment (duodenum), and the jejunum (or the small intestine’s 2nd segment). This process will help reduce the amount of absorbed calories and nutrients.

After the surgery, patients normally spend two to three days recuperating in the hospital. Patients are only discharged when there is no more discomfort and pain, and when they are already able to keep down liquids or pureed food.

Recovering patients will be on a liquid diet for a number of weeks after surgery. As patients gradually switch to a solid food diet, they will feel full very quickly as the new stomach pouch will initially hold only about a teaspoonful of food. Although the pouch will eventually expand, it will only be able to contain around 1 cup of thoroughly chewed food as compared to a normal stomach’s capacity of up to 1 quart.

Patients will be required to take in supplements to make up for the nutrients lost as food will now move more quickly through the digestive system. Only small meals scattered throughout the day is required of patients as compared to large meals, which their stomachs cannot accommodate. Regular exercise is also important.

People who are more than 100 lbs overweight or those with a Body Mass Index (BMI) of more than 40 will experience reduced essential hypertension, reversal of Diabetes mellitus type 2, relief from lower back and joint pain, reduced risk of heart disease, and reduced instances of obstructive sleep apnea after undergoing gastric bypass surgery.
Gastric Banding Surgery
LAP-BAND Surgery is a minimally invasive weight loss procedure requiring no stomach stapling or re-routing of internal organs. In the U.S. it is the second most common weight loss surgery performed (after gastric bypass surgery). The name "LAP-BAND" comes from the surgical technique used (laparoscopic) and the name of the product used (gastric band). The LAP-BAND consists of a silicone ring that is placed around the top of the stomach. Inside the LAP-BAND is an inner balloon, which connects to the access port through a small tube. The access port is placed deep under the skin on the left-hand side of the stomach and is adjusted with a shot of saline solution that tightens or loosens the band according to personal weight loss goals. This fluid regulates the amount of satiety (feeling of fullness) and satiation (feeling satisfied after meals) felt by the patient.

On average, laparoscopic adjustable gastric banding will help you lose about 40 percent of your excess weight - if you are 100 pounds overweight you can expect to lose 40 pounds. Unlike gastric bypass surgery, gastric banding does not interfere with food absorption, so vitamin deficiencies are rare after gastric banding.

In the first few weeks after your surgery, you will be on a liquid diet since only thin liquids will be tolerated by your stomach at that time. As you heal, you will progress in steps towards eating solid food.
Once you can eat solid foods again, you will need to pay close attention to your diet. You should not drink liquids during or immediately after meals as they will flush food through the reduced stomach pouch, which means you will not get the prolonged feeling of satiety needed to help you eat less. It is recommended that you eat only three small meals a day and make sure that these meals contain adequate nutrients. You will need to make good food choices and learn to avoid problem foods, such as high-fiber, high-fat, and dry foods, since these are more difficult for the small stomach pouch to digest. Good food choices include fruits and vegetables, lean protein, some bread and cereal, and some dairy products.

People who are more than 100 lbs overweight or those with a Body Mass Index (BMI) of more than 40 will experience reduced essential hypertension, reversal of Diabetes mellitus type 2, relief from lower back and joint pain, reduced risk of heart disease, and reduced instances of obstructive sleep apnea after undergoing gastric bypass surgery.
