There are many options that can be used in losing weight. One of the methods that has gained a lot of popularity in recent times is weight-loss surgery. Examples of surgical procedures that may be conducted include sleeve gastrectomy, bypass surgery and gastric banding. Each of these procedures has associated advantages and disadvantages. If they have plans of having gastric sleeve surgery Houston patients need to understand a number of things.
The sleeve gastrectomy operation may be done in isolation or may be the first stage of the more aggressive bypass procedure. To perform it, an incision is first made along the length of the stomach. A large part (between 75% and 90%) is removed which effectively converts the stomach into a tubular or sleeve-shaped organ. The next step is to close the incision area using staples or sutures.
The objective of gastrectomy (as is the case with other bariatric surgeries) is to limit the amount of food intake during a single meal. The stomach will fill faster than before and stimulate early satiety. After the removal of a large mucosal surface of the stomach, the production of gastric hormones is also affected. There is a suppression in the appetite and the blood glucose levels remain fairly normal.
The outcomes of this operations are quite impressive for most people. For instance, it has been shown that up to 50% of body weight can be shed off in a matter of months. This is comparable to the results of gastric bypass but without the unwanted side effects. This operation is also advantageous in that the nerves that supply the stomach are preserved and the function of stomach valve mechanisms remain intact.
There are two main techniques that are employed: the open technique and the laparoscopic surgical option. The use of laparoscopy is by far, the more preferred options due to its many advantages over the open technique. One of these advantages is the fact that smaller incisions are used hence the resultant pain is a lot less. There is a lower risk for infection and patients generally have a quicker recovery.
A typical candidate is an individual who has excess weight and has been unable to manage it using lifestyle options. They should have a body mass index of not less than 40 but lower values are acceptable if the person already suffers from obesity related complications such as sleep apnea, high blood pressure and diabetes. Another important consideration is that major risks to the operation should not exist.
Some potential complications to this operation exist. Some are complications that may be seen with any surgical operation while others are specific of this operation. The general complications include injury to other organs, excessive blood loss and infections. More specific complications include leakage of digested food, gradual stomach dilatation and esophageal spasms. The procedure cannot be reversed even when complications set in.
There are several types of weight loss surgery that exist. The choice is determined by factors such as the magnitude of problem, skill of the surgeon as well as patient preference. Sleeve gastrectomy is among those that are commonly performed. It is a procedure that has satisfactory results in the majority of people but has a major downside in the fact that it is not reversible.
