Types of Bariatric Procedure
There are a dozen different types of bariatric procedure, some more common than others. But they nearly all work by one of two principles: restriction of content or lowering absorption of nutrients.
Gastroplasty, for example, is a procedure in which the stomach is stapled near the top, altering its effective size. A smaller stomach has many effects, but the chief one is that it leads to a sense of fullness sooner. That discourages consuming large amounts of food, reducing calorie intake.
A similar procedure called Gastric Bypass (for which there are many names, such as Roux-en-Y GB, and wide variation in specific techniques) involves creating two unequal stomach compartments. The result is to reduce the available 'storage space' for food by about 95%. Food that enters this tiny stomach empties into the upper intestine.
A similar technique called Biliopancreatic Diversion or BPD is much less common today. In this method, about half the intestine is bypassed by being sliced and rejoined to the ileum near the end of the small intestine, 2-4 feet above the colon (large intestine).
It has the effect also of reducing absorption of ingested food inside the intestine, but can lead to nutrient deficiency. It's being replaced by less risky procedures with fewer side effects in many cases. One such is a variation that actually removes a section of the intestine, a procedure known as a Duodenal Switch, which creates a more cylindrical stomach. (Sometimes the two techniques are combined in a single surgery.)
There are other ways to reduce the volume of the gastrointestinal system and one is rapidly becoming the most popular for reasons of safety, convenience, and effectiveness. It is generically referred to as the lap band. The LAP-BAND® is an inflatable device from Allergan that is surgically wrapped around the stomach/intestine.
The plastic device is quite safe and rarely rejected by the body's immune system. It does require that the patient undergo periodic adjustments (usually four over 1-2 years). As the stomach shrinks from adjusting to containing and processing less food and weight loss proceeds, the band needs to be tightened if it's to continue being effective. That's done by a physician who injects saline into the device through a port lying just under the skin.

What To Expect After The Weight Loss Surgery
Constipation is a commonplace occurrence, but easily treated or minimized. Taking a little bit of mineral oil might help. Avoiding high-fiber foods is critical. Your nutritionist and/or physician will give you well ahead of time a detailed post-op diet that needs to be followed closely. Laxatives are to be avoided, except on the specific recommendation of the doctor and even then you should seek an extra opinion.
Gallstone formation happens in up to 50% of gastric bypass surgery patients. About 15-25% require taking out the gallbladder as treatment in those cases. Here again, reducing the odds is dependent on strict adherence to a carefully worked out diet. Many foods and liquids present unique odds of encouraging (or discouraging) the creation of gallstones.
If or when you believe you have got one - often signaled by moderate to severe pain in the gastrointestinal tract - it's vital to get medical attention right away. It usually is simple indigestion or it may be something worse. Any blood in the stool really should be investigated immediately. Most gallstone issues present minor health problems - even when they're very painful - but the proper diagnosis and rapid treatment certainly are a must.

Bariatrics And Bariatric Procedures
For those who are grossly obese (a BMI of 40 or more) and have tried diet (and possibly exercise), a bariatric procedure may be the best - even the only - option. Even so, physicians will usually insist on a commitment to a specific post-procedure bariatric diet, along with other lifestyle changes. Vitamins and other supplements often form a part of that, but lifestyle adjustments are too.
Here's the harsh, straight truth: even after bariatric surgery it is essential to stay with a lifelong healthy diet and - where and when proper, an workout routine. There simply is no substitute for a lifelong dedication to change - modification of eating habits, modification of attitude toward correct weight upkeep and overall wellness. Those unprepared to make that committal will have exhausted their money and suffered pain and risk for no gain.
That kind of commitment is really easier to maintain after the bariatric procedure. Due to the fact that the decision to get the surgical operation done in the first place expresses some course of commitment to lose weight and effort to keep off the fat.
Once you go through the operation, you'll see yourself getting full much quicker, which assists conquer those formerly uncontrollable urges. You'll find that what you consume and drink doesn't place on the pounds like it used to. The main causes for the weight loss are in essence two folded. First off you are having less calories because of your improved eating habits and secondly the bariatric surgery has the effect that foods are ingested much more slowly.
