Weight loss surgeries (also known as bariatric operations) are becoming increasingly common. The surgical option is particularly helpful to persons dealing with morbid obesity and in whom the traditional non-surgical options have failed to yield positive results. The objective of such operations is to reduce the capacity and surface area of the stomach which effectively reduces the amount of food absorbed. If they intend to have gastric bypass surgery Houston obese patients need to know a number of things.

There are certain criteria that are used in choosing candidates to undergo the surgery. The first is that they must have tried out engaging in physical exercise and must also have been on a proper diet for not less than 6 months. Regular exercise is defined as at least 30 minutes of intense physical activity on 3 to 5 days of the week. A proper diet is one that has less carbohydrates and more fruits and vegetables.

The candidate is also required to have a body mass index, BMI, of at least 40. If the BMI is less than this very little or no benefits at all will be realized. The exception to this is candidates who are suffering from or are at risk of weight-related complications such as stroke, cardiac disease, high blood pressure, type 2 diabetes and gastro-esophageal reflux disease among others. In such cases, a BMI value of between 35 and 40 is acceptable.

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 many techniques that can be employed when performing a gastric bypass procedure. The Roux-en-Y technique is one of the most popular. It involves a two-step procedure the first of which is the conversion of the stomach into a pouch. This pouch is capable of holding just a small amount of food unlike the original stomach. The second step is to join this pouch to the second intestinal portion (bypassing the first in the process).

The roux-en-Y technique is highly preferred because it can be performed through small incisions. The scars resulting from the operation are quite small and almost inconspicuous in most cases. Complications are also quite rare when this technique is used. Among them is the possibility of erosion of silicon bands and staples used in fashioning the pouch. However, the process of erosion takes many years.

Dumping syndrome is another complication that prospective candidates need to be aware of. Associated symptoms include generalized body weakness, diarrhea, sweating, nausea and fainting among others. All these symptoms are thought to be the result of food moving rapidly through the digestive tract. They typically are experienced are experienced thirty or so minutes after eating.

There is an increase in the demand for gastric bypass procedures all over the world. This demand is mainly being driven by an increase in the prevalence of obesity. The good news is that the procedure has become significantly effective and safe thanks to advances that have been made in surgical practice. There is a need for one to complement the surgery with desirable lifestyle changes so as to realize the optimal results.
