What is Gastric Bypass Surgery?
Gastric bypass surgery makes the stomach smaller and allows food to bypass part of the small intestine.A Person will feel full more quickly than when stomach was its original size. This procedure reduces the amount of food a person eats and thus the calories consumed. Bypassing part of the intestine also results in fewer calories being absorbed. This leads to weight- loss.
For whom is Gastric Bypass Surgery? Generally, gastric bypass surgery is reserved for people, who are unable to achieve or maintain a healthy weight through diet and exercise, are severely overweight, and who have health problems as a result. Gastric bypass may be considered if: § If a person’s body mass index (BMI) is 40 or higher (extreme obesity).
§ If a person’s BMI is 35 to 39.9 (obesity), and he/she has a serious weight-related health problems such as diabetes or high blood pressure.
Gastric bypass surgery doesn’t replace the need for following a healthy diet and regular physical activity program. In fact, the success of the surgery depends in part on patient’s commitment to following the guidelines given to him/her about diet and exercise. As a patient considers weight-loss surgery, he/she should be mentally prepared to make the life-style changes such has proper dietary habits, proper exercise regime
What Are The Types Of Gastric Bypass Surgeries?
Roux-en-Y gastric bypass (RGB):
This operation is the most common gastric bypass procedure performed. First, a small stomach pouch is created by stapling part of the stomach together or by vertical banding. This limits how much food a patient can eat. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the duodenum as well as the first portion of the jejunum. This causes reduced calorie and nutrient absorption. This procedure can now be done with a laparoscope (a thin telescope-like instrument for viewing inside the abdomen) in some people. This involves using small incisions and generally has a more rapid recovery time.
Extensive gastric bypass (biliopancreatic diversion:
In this more complicated gastric bypass operation, the lower portion of the stomach is removed. The small pouch that remains is connected directly to the final segment of the small intestine, thus completely bypassing both the duodenum and jejunum. Although this procedure successfully promotes weight loss, it is not as widely used because of the high risk of nutritional deficiencies. Gastric bypass operations that cause malabsorption and restrict food intake produce more weight loss than restriction operations, which only decrease food intake. People who have bypass operations generally lose two-thirds of their excess weight within 2 years.
Proceduer of Gastric Bypass Surgery:
In gastric bypass, the surgeon creates a small pouch at the top of the stomach and adds a bypass around a segment of small intestine. The surgeon staples the stomach across the top, sealing it off from the rest of the stomach. The resulting pouch is about the size of a walnut and can hold about an ounce of food. The pouch is physically separated from the rest of the stomach. Then, the surgeon cuts the small intestine and sews part of it directly onto the pouch.
This redirects food, bypassing most of the stomach and the first section of small intestine, the duodenum (doo-o-DEE-num). Food enters directly into the second section of small intestine, the jejunum (jay-JOO-num), limiting the patient’s ability to absorb calories. Even though food never enters the lower part of the stomach, the stomach stays healthy and continues to secrete digestive juices to mix with food in small intestine.
Some surgeons perform this operation by using a laparoscope — a small, tubular instrument with a camera attached — through short incisions in the abdomen (laparoscopic gastric bypass). The tiny camera on the tip of the scope allows the surgeon to see inside the abdomen.
What can a patient expect after gastric bypass surgery? Patient won’t be allowed to eat for one to two days after the surgery so that the stomach can heal. Then the patient has to follow a specific dietary progression for about 12 weeks. This begins with liquids only, proceeds to pureed and soft foods, and finally to regular foods.
With stomach pouch reduced to the size of a walnut, patient will need to eat very small meals throughout the day. In the first six months after surgery, eating too much or too fast may cause vomiting or an intense pain under breastbone. The amount patient can eat gradually increases, but patient won’t ever be able to return to old eating habits.
Within the first two years of surgery the patient can expect to lose 50 percent to 60 percent of patient’s excess weight. If the patient closely follows dietary and exercise recommendations, he/she can keep most of that weight off long-term.
Benefits of Gastric Bypass Surgery:
In addition to dramatic weight loss, gastric bypass surgery may improve or resolve the following conditions associated with obesity:
- Loss of high blood pressure: 70% of patients are able to go off all blood pressure medications post-op.
- Loss of high blood cholesterol: 80% of patients develop normal cholesterol levels within 2-3 months after surgery.
- Type 2 diabetes
- Obstructive sleep apnea
- Reduced risk of heart disease
- Increased probability of reducing all need for medication in a diagnosed Type II Diabetes patient.
- Reversal of borderline diabetes
- Reduced asthma attacks, and in some cases a total discontinuation.
- Reduced Respiratory Insufficiency: Many patients find that within just months of the surgery they have almost no respiratory problems at all and can participate in normal activities they have missed out on for years.
- Relief of Sleep Apnea Syndrome
- Relief from Acid Reflux Disease
The improvements observed in type 2 diabetes, high blood pressure and high blood cholesterol may significantly decrease the risk of cardiovascular events in individuals who have undergone gastric bypass surgery compared with those treated through other means. Gastric bypass surgery has also shown to improve mobility and quality of life for people who are severely overweight.
