There has been a steady increase in the number of weight-loss surgeries performed all over the world. The operations, also known as bariatric operations, are performed with the aim of reducing the stomach volume and, by extension, the surface area used for absorption. The surgeries usually become an option for morbidly obese individuals that do not respond to other interventions. There are several benefits on gastric bypass surgery Houston residents can get from the procedure.
Several criteria are used in selecting potential candidates to undergo the operation. One of them is that lifestyle options should have been tried for a period of six months or more. Such will include a proper diet and regular physical exercise. A proper diet should have a low amount of carbohydrate and protein and more vegetables and fruits. As for exercise, the minimum is thirty minutes of intense physical activity three to five days a week.
The candidate should have a body mass index, BMI, of not less than 40. If the BMI is less than 40 then the benefits may not be fully appreciated. A number of patients may qualify even with lower values. Such include patients that are already suffering from weight-related diseases such as hypertension, diabetes, sleep apnea and cardiac disease or are at a risk of the same. The cut off BMI value in this case is 35.
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.
Another major complication is what is known as dumping syndrome. The syndrome is caused by food emptying rapidly through the digestive tract. Symptoms may include fainting, nausea, generalized body weakness and nausea among others. They typically set in within thirty minutes of eating and are more likely to be experienced when one eats sugary foods.
Gastric bypass surgeries are increasingly becoming an option for weight loss thanks to the rising prevalence of life threatening obesity all over the world. Newer techniques have not only made this operation effective but have also significantly reduced the rate of complications. It is important that one complements the operation with lifestyle changes if they are to realize maximum benefits.
