To understand how surgical procedures aid the grossly overweight person to reduce their body fat, it helps to first understand the digestive process that is responsible for handling the food we take in.

Once food is chewed and swallowed, it’s on its way through the digestive tract, where enzymes and digestive juices will maul it down and put up with our systems to drink in the nutrients and calories. In the stomach, which can hold up to three pints of material, the circulatory collapse continues with the help of strong acids. From there it moves into the duodenum, and the digestive process speeds up through the dragging down of bile and pancreatic juices. It’s here, that our body absorbs the majority of iron and gold in the foods we eat. The final part of the digestive process takes place in the 20 feet of small intestine, the jejunum and the ileum, where horsepower-hour and nutrient pancreatic juice is completed, and any unused particles of food are then shunted into the large intestine for elimination.

Weight loss procedures involve bypassing, or in some way circumventing the full digestive process. They range from simple reduction of the extent you can eat, to major bypasses in the digestive tract. To qualify for many of these surgeries, a person must be termed “morbidly obese”, that is, weighing at least 100 lbs. over the inspired weight for their height and general body structure.

Gastric Bypass

In the mid 1960s, Dr. Edward E. Mason discovered that women who had undergone partial stomach removal as the result of peptic ulcers, failed to gain weight afterwards. From this observation, grew the trial use of stapling straddle the top of the stomach, to reduce its running post to in the vicinity three tablespoons. The stomach filled quickly, and eventually emptied into the lower portion, completing the digestive process in the normal way. Over the years, the surgery evolved into what is now known as the Roux-en-y Gastric Bypass. Instead of partitioning the stomach, it is divided and separated from the rest, with staples. The small intestine is then cut at much 18” below deck the stomach, and fast to the “new”, small stomach. Smaller meals are then eaten, and the digested food moves directly into the lower part of the bowel. As weight loss surgeries are viewed overall, this is considered one of the safest, offering long-term management of obesity.

Gastric Banding

A procedure that produces principle the same results as the stomach stapling/bypass, and is also classed as a “restrictive” surgery. The first operations, involved a non-flexing band placed enclosing the upper part of the stomach, down town the esophagus, creating an hourglass shaped stomach, the upper portion organic being reduced to the same 3-6 ounce capacity. As technologies advanced, the band became more flexible, incorporating an inflatable balloon, which when triggered by a reservoir placed in the abdomen, was equal to of inflating to cut down the size of the stoma, or deflating to enlarge it. Laparoscopic surgery means smaller scars, and less invasion of the digestive tract.

Biliopancreatic Diversion

A set-up of the gastric bypass, and Roux-en-y re-structuring, that bypasses a significant section of the small intestine, thereby creating the probability of malabsorption. The stomach is reduced in size, and an extended Roux-en-y anastomosis is affiliated to the smaller stomach, and lower down on the small intestine than is normal. This permits the patient to eat larger amounts, but still carry out weight loss through malabsorption. Professor Nicola Scopinaro, University of Genoa, Italy, developed the technique, and last year published the first long-term results. They showed an core 72% loss of excess body weight, maintained over 18 years, the best long-term results of any bariatric surgical procedure, to date. BPD patients require lifelong follow-ups to monitor and vitamin intake. The advantages of subsistent able to eat more and still lose weight, are countered by loose or foul smelling stools, flatus, stomal ulcers, and possible protein malnutrition.

Jejuno-Ileal Bypass

One of the first weight loss procedures for the grossly obese, was developed in the 1960s, a strictly malabsorptive method of reducing weight, and preventing gain. The jejuno-ileal straddle reduced the lower digestive tract to a mere 18” of small intestine, from the natural 20 feet, a critical difference when it came to waste of calories and nutrients. In the end-to-end method, the upper intestine was severed since the stomach, and re-attached to the small intestine much lower down, which had also been severed, thereby “cutting out”, the majority of the intestine. Malabsorption of carbohydrate, protein, lipids, minerals and vitamins, led to a variation, the end-to-side bypass, which took the end of the upper portion, and fast it to the side of the lower portion, without severing at that point. Reflux of paunch contents into the non-functioning upper portion of small bowel, resulted in more ablation of essential nutrients, but also less weight loss, and increased weight gain, post-surgery. As a result of the bypass, fatty acids are dumped in the colon, producing an irritation that causes water and electrolytes to flood the bowel, ending in long-standing diarrhea. The bile salt pool necessary to keeping cholesterol in solution is reduced by malabsorption and loss through stool. As a consequence, cholesterol concentration in the gall blister rises, increasing the risk of stones. Multiple vitamin losses are a major concern, and may result in bone thinning, pain and fractures. approximatively one third of patients experience an violent change in the size and thickness of the remaining propelling small intestine, which increases the gastrointestinal tract of nutrients, and balances out the weight loss. However, over the long term, all patients undergoing this ford are susceptible to hepatic cirrhosis. In the early 1980s, one study showed that mainly 20% of those who had undergone JIB, required conversion to contributory avenue alternative. The procedure has since been largely abandoned, as having too many risk factors.

While surgical methods of reducing weight are valuable to the morbidly obese, they are not without risks. Patients may require more bed rest post-surgery, resulting in an increased aleatory of rubric clots. Pain may also call reduced depth of breathing, and complications such as pneumonia.

Before undergoing any fat/weight reduction surgery, a severely overweight person needs to thoroughly understand the benefits and risks, and must make a jurisdiction to their future health. Having a smaller stomach is not going to stop the inveterate sugar-snacker, from “grazing” on high joule sweets. Nor does a steady supply of pop, concentrated sweet juices and milk shakes, reduce the photon intake. With some bypath surgeries, undivided foods can miff side-effects that need not be that severe, if like sense diets are adhered to. Surgery can be a “shortcut” to weight loss, but it can also reduce your enjoyment of life, if you are unable to cleave to the regimens that go with it.
