Research shows that the number of weight loss surgeries has been increasing steadily over time. The surgeries, also termed bariatric operations, are mainly performed with the objective of reducing the volume of the stomach and effectively the surface that is used in absorption of food. Bariatric surgery is an option for obese patients that have been unsuccessful in reducing weight using lifestyle options. There are a number of things on gastric bypass surgery Houston patients should understand.
A number if criteria are used in choosing the potential candidates to undergo this operation. Among them is the fact that one should have been on lifestyle management for a minimum of six months. Lifestyle includes both a proper diet and regular physical exercise. The ideal diet comprises less carbohydrates and more of fruits and vegetables. Exercise is considered adequate if there are thirty minute sessions of intense activity on three to five days every week.
The potential candidate should ideally have a body mass index (or BMI) of at least 40. If this value is low then the benefits are limited. Exceptions to this rule exist. For instance, for patients that are suffering from weight related complications such as diabetes, hypertensive disease, cardiac conditions, gastro-esophageal disease and sleep apnea among others. A BMI value of between 35 and 40 is acceptable among these patients.
You will need to undergo a medical checkup by your doctor before being scheduled to undergo the operation. This checkup includes both a history and a physical examination both aimed assessing the suitability of a potential candidate. A number of tests have to be performed to screen for possible surgical risks. Such will include a full blood count, renal function tests and liver function tests aiming others.
There are various techniques of gastric bypass being used currently. One of the most commonly used types is the Roux-en-Y technique. In this approach, the first step is to fashion the stomach into a small pouch (equivalent to the size of an egg). The next step is to connect the pouch so formed to the second part of the intestine (the jejunum). The first portion is bypassed in this process.
The roux-en-Y technique makes it possible to perform the operation using small incisions. The result of this is that the scars resulting from the operation are quite small and the complications are also fewer. One of the complications that may be encountered is the erosion of staples and silicone bands that are used in creating the pouch. This may be seen after some years but is thankfully quite rare.
Dumping syndrome is another major complication associated with this type of surgery. The syndrome is characterized by fainting, generalized body weakness, nausea, diarrhea and sweating among others. These symptoms are thought to result from the rapid movement of food from the stomach to the intestines. They will typically be experienced after about 30 minutes following the ingestion of food.
Gastric bypass operations are now common procedures in many places all over the world. This has been fueled by, among other factors, increased incidence of obesity. The surgeries have b e3come safer and effective hence more acceptable. The general advice is that one should combine the surgery with lifestyle changes so as to increase the chances of success.
