Gastric Bypass Surgery is a proven weight loss surgery method for permanent weight loss as well as a potential cure for Type II Diabetes and other conditions related to morbid obesity (co-morbidities). Basically, the surgery helps lose weight of patients by changing how their stomach and small intestine handle the food they eat. The surgery is recommended when non-surgical treatments, such as diet, exercise and medicines have not worked. Generally, the surgery is considered for patients who have a body mass index of 40 or higher or if there is a life threatening or disabling condition related to the patients weight.
Overweight Americans and Canadians, who are worried with high bariatric surgery prices, can find low-cost bariatric surgeries in Mexico. The prices of gastric bypass surgery in Mexico, draw thousands of patients every year to undergo surgery in Mexico.
As stated in a report by The World Health Organization (WHO) in 2008, almost more 200 million men and almost 300 million women were obese. The report states that the crucial threat for deaths throughout the world is obesity. More than 2.8 million adults are dying because of the excess weight and obesity. Some of the complications suffered by obese people is type 2 diabetes, muscle disorders, bone diseases, cardiac problems, asthma, some types of cancers and infertility. All these health problems not only make life miserable but also threaten their longevity.
An ideal solution would be bariatric procedures, which would eliminate or lessen co-morbidities in the majority of patients. To learn more about gastric bypass, please contact our helpful staff.
About Gastric Bypass
Gastric bypass surgery, otherwise called roux-en-y gastric bypass, is a restrictive and malabsorptive weight loss procedure. Gastric bypass uses two fundamental techniques to induces weight loss which proves to be successful in the majority of patients. Studies have shown the reduction in severity or the complete remission of various co-morbidities (including type-2 diabetes, hypertension, high cholesterol, sleep apnea, etc.) is accomplished with gastric bypass.
In 2000, a study of 500 patients showed that 96 percent of co-morbidities were improved or resolved.
The restrictive portion of gastric bypass is when the stomach is cut into a small portion, this new stomach is called the stoma, which is significantly reduced. The remaining stomach is stapled and left still attached to the intestine which allows the stomach juices to pass to the intestines. This small reduction induces feelings of being satisfied, even when eating very small amount of food.
The malabsorptive portion is when the intestines are re-arranged and attached to the stoma. This rearranged intestines causes malabsorption or less calories to be absorbed. This allows calories to pass through your intestines, which means less less calories are being consumed.
Because of this two step process patients will roughly 70% of their excess weight.
Gastric Bypass Preparation
Preparation before the procedure includes a thorough and extensive screening process like blood tests, physical exams, bleeding and clotting time, and other needed laboratory work-ups. If the patient is smoking, the act is prohibited for weeks prior to the surgery. Eating will also be prohibited hours before to prevent aspiration. The operation requires a two to four day stay in the hospital and is done under general anesthesia.
How Gastric Bypass Works
Roux-En-Y Gastric bypass process is one of the most performed bariatric surgeries, being the gold standard in bariatrics. Gastric bypass (RNY) is suggested people with a body mass index (BMI) higher than 35. The gastric bypass reduces the size of the stomach, but making a stoma Ð a small pouch. The malabsorptive part is performed when the small intestines are changed, thus inducing food to pass through without being absorbed. These two techniques provide high expected weight loss.
During the surgery, the surgeon uses surgical staples to create a pouch from the upper part of the stomach separating it from the rest. A section of the intestine is then bypassed and re-connected to the pouch. This then creates a shorter route for the food to pass in the digestive system, thus lesser food is absorbed in the body. Gastric bypass can be done by making a large incision in the abdomen (an open procedure) or by making a small incision and using small instruments and a camera to guide the surgery (laparoscopic approach). Other than the small size of the digestive system, some scientists also believe that weight loss following bariatric surgery is also the result of diminished blood cells of a recently discovered hormone called ghrelin, which is secreted by endocrine cells within the stomach. Blood ghrelin levels rise prior to meals and in the face of food restriction or starvation.
Risks of Gastric Bypass Surgery
Just like any surgery, gastric bypass involves a set of risks. Risks common to all surgeries for weight loss include an infection in the incision, a leak from the stomach into the abdominal cavity or where the intestine is connected which may lead to peritonitis, and a blood clot in the lung. Ulcers also develop 5 to 15% of the time. Over time, the problems that may occur include, breakdown of the pouch, which would require another surgery to repair it, narrowing of the opening between the stomach pouch and the small intestine, low calcium levels, which can cause early osteoporosis. Also, problems such as gallstones and gallbladder attacks, gastritis, heartburn, stomach ulcers, poor nutrition, vomiting from eating more than your stomach pouch can hold, dumping syndrome when the contents of the stomach move through the small intestine quickly, incisional hernia and kidney stones may occur over time. An iron and vitamin B12 deficiency also occurs more than 30% of the times. About 50% of those with an iron deficiency develops anemia.
Benefits of Gastric Bypass
Weight loss is the major benefit of gastric bypass surgery. An expected weight loss of 65% to 80% of excess body weight is typical of most large series of the surgery. Most people lose about 10 to 20 pounds a month in the first year following the procedure. Comorbidities accompanying morbid obesity may also be corrected if the surgery is performed:
- Hyperlipidemia is corrected in over 70% of patients. Essential hypertension is relieved in over 70% of patients and medication requirements are usually reduced in the remainder.
- Obstructive sleep apnea is markedly improved with weight loss and bariatric surgery may be curative for sleep apnea. Snoring also improves in most patients.
- Over 90% of patients with type II non-insulin dependent diabetes mellitus are expected to be off medication.
Problems like, asthma, joint pain, arthritis, re flux, fatigue and shortness of breath are also improved or cured. In summary, the procedure causes an overall increased sense of well-being and an improved ability to engage in physical activity.
Advantages of Gastric Bypass:
- Reversible, Can be revised to Duodenal Switch
- Produces high expected weight loss
- Can reverse type 2 diabetes and other comorbidities
Disadvantages of Gastric Bypass:
- Requires high levels of patient dedication
- Dietary restrictions are more than other surgeries
Gastric Bypass Results
After the surgery, a restriction of eating for one to two days to allow the stomach to heal may be required, to be followed by a specific diet for about 12 weeks. Activities can be resumed after the patient can move around without a lot of pain usually in 3 to 5 weeks. Following the procedure, the patient needs to follow the exercise and nutrition guidelines established by the physician and the dietician to lose weight and avoid complications of the procedure.
