Gastric Bypass surgery has become the most common form of weight loss surgery in the world. Due to it results in reliable weight loss with minimal risks and minimal side effects. Gastric bypass surgery is performed by a surgeon, the surgeon staples off a large section of the stomach, leaving a tiny pouch. The staple gun cuts and seals the stomach simultaneously. As part of the surgery the surgeon will perform a ‘leak test”, insuring the stomach has sealed prior to the patient being released. Patients can no longer eat as much as they did before surgery, due to the small pouch only accommodating a few ounces of food at a time. By limiting the food intake weight loss will happen naturally. Due to the smaller stomach, some of the nutrients and calories in your foods will no longer be absorbed, requiring most patient to take multivitamin, B12, iron and calcium, and avoiding sweets and fatty foods. Most surgeons advise the ideal candidates for this surgery are those who are 100 pounds or more overweight. Although many other factors come into play when a surgeon evaluates a patient.

The benefits of Bariatric surgery go beyond what the eye can see. If you are morbidly obese then bariatric surgery may be safer than carrying around those extra pounds. If you’re dealing with diabetes, bariatric surgery may improve or resolve the disease. Bariatric surgery may improve or resolve diabetes. Bariatric Surgery may also lower your risk for other serious conditions, such as heart disease, high blood pressure, stroke, arthritis, and certain malignancies.
A variety of bariatric surgeries are available, but all procedures are either malabsorptive, restrictive, or a combination of the two. Malabsorptive procedures change the way the digestive system works. Restrictive procedures are those that severely reduce the size of the stomach to hold less food, in both cases the digestive functions remain intact.
Rapid and long-term weight loss without implants or rerouting intestinal tract
In gastric sleeve surgery, about 60 percent of the stomach is removed laparoscopically, leaving behind a sleeve of the stomach. This smaller stomach restricts the amount of food a patient can eat and leads to significant weight loss.
In some gastric sleeve patients, this procedure is performed instead of gastric banding or gastric bypass surgery. In others, especially those at higher surgical risk, it is offered as the first part of a two-stage surgical plan. As weight is lost following the gastric sleeve procedure and patients become healthier, they can safely be offered a second operation, either gastric bypass or gastric banding, for additional weight loss.
Minimally invasive procedure with risk of few complications
Gastric banding involves placing a silicone gastric band with an inflatable inner collar around the upper stomach to restrict food intake. This creates a small pouch and a narrow passage to the lower stomach. This small passage delays the emptying of food from the pouch and causes a feeling of fullness. The silicone gastric band can be tightened or loosened over time to change the size of the passage.
Gastric banding is usually performed laparoscopically, meaning that the surgeon makes small incisions as opposed to one large one. It is usually done on an outpatient basis.
Rapid and long-term weight loss
The most common type of bariatric weight-loss surgery, gastric bypass, works by laparoscopically reducing the volume of the stomach. The intestines are rerouted and a small stomach pouch is created by stapling off the main body of the stomach. Food flows through this pouch, bypassing the main portion of the stomach and emptying slowly into the small intestine where it is absorbed. Gastric bypass surgery restricts food intake and reduces hunger to promote healthy weight loss.
Gastric bypass patients can expect to lose one-half to two-thirds of their excess weight within two years and they should be able to maintain their weight loss for five years and beyond.
For those regaining weight following gastric bypass
Over years following gastric bypass surgery, some patients will regain weight. This may be caused by an enlarged pouch, which can be repaired through a variety of options. Surgeons at UC San Diego Health System are exploring endoscopic options involving inserting instruments through the mouth to reduce the size of the stomach pouch and the opening to the small intestine. This has the effect of reducing the stomach to the size that was achieved by the original gastric bypass surgery and promotes additional weight loss.
The new minimally invasive weight-loss surgery
The stomach is folded inward in the gastric plication procedure.Gastric plication is a newer minimally invasive weight-loss surgery technique that reduces the size of the stomach capacity to approximately three ounces. The procedure does not involve the use of an implant (such as gastric banding). Also, unlike the gastric sleeve procedure, gastric plication may be reversible because a portion of the stomach is not removed. In addition, unlike gastric bypass, the gastric plication procedure does not involve rerouting and reconnecting the intestines.
It is a restrictive weight-loss surgery, meaning that it restricts the amount of food the stomach can hold. You will feel full sooner so you won’t want to eat as much.
Gastric balloons are inserted under sedation in a procedure which takes 20 to 30 minutes. It is a relatively minor procedure, but it may take your stomach a little while to get used to the balloon. You will usually be able to go home the same day, or the day after the balloon has been inserted.
In a small number of cases, patients may not be able to tolerate the balloon for the full 6 month period and when this happens, it will need to be removed early. There is a possibility this may happen in the first few days after the balloon is placed, if side effects (including nausea and vomiting) do not resolve or are worse than anticipated.
Choosing an option that is best for the desired results is not an easy choice. Speaking with an experienced surgeon is the only way to be certain. Find a list of experienced surgeons in InternationalMDS.com weight loss surgeon directory
