What is Gastric bypass?

Within bariatric surgeries, gastric bypass is one of the most common procedures for morbidly obese patients who have not responded favorably to other less radical treatments to lose between 50 to 60% of their excess weight. 

This procedure’s technique consists of dividing the stomach in two; the upper part, which is smaller in size, is connected to the small intestine so that the stomach absorbs fewer calories by reducing the intake as a result of the reduced space. 

Other reasons why this procedure is recommended is that the patient suffers from hypertension, obstructive sleep apnea, and type 2 diabetes.

This surgery can be open or laparoscopic. The latter is more recommended because it is less risky and minimizes recovery times, because instead of making a large incision, small cuts are made through which a small camera and the special surgical equipment are inserted.

Before the procedure:

You will be asked for various tests to see if you can undergo this surgery, including blood tests and ultrasounds, but depending on your case, you will be given complementary tests. You will also be given advice on nutrition and psychological support, asking you to avoid alcohol and tobacco.

After the procedure: 

If the gastric bypass is performed laparoscopically, it will be necessary for you to remain hospitalized for three or four days and you will recover in approximately one month.

Potential risks:

As it is a major surgery, gastric bypass has various risks, regardless of the usual risks due to anesthesia and surgery itself, including:

  • Ulcers in the stomach and gastritis.
  • Damage to the stomach or other organs.
  • Leaks between the two divided parts of the stomach. 
  • Abdominal and intestinal blockages.
