Gastric bypass surgery is a surgical procedure that is carried out to help you lose weight by reducing the size of your stomach. This procedure is recommended only if other methods such as diet and exercise have failed to produce tangible results. Gastric bypass surgery causes less complications when compared to other bariatric surgeries.

This surgery is primarily done to bring your weight at optimal levels. It also helps to reduce the risk of some life threatening diseases such as a stroke, sleep apnea and high blood pressure. This surgery is recommended for people who have a body mass index greater than 40 (considered to be morbidly obese). However, it is important to note that this surgery is only used as a last resort when other methods to reduce weight have failed.

Procedure-

  1. The procedure begins with anesthesia being administered to the patient.
  2. The surgeon then divides the stomach into two parts by using staples.
  3. The upper portion of the stomach is reshaped smaller than the bottom portion because the food that you eat will only reach the upper part.
  4. The next step is the bypass, wherein the upper part of the stomach is connected to the small intestine.
  5. The size of the stomach now achieved is designed in such a way so that you eat less food; the bypass makes the body absorb fewer calories.

Post-Procedure

  • Initially, you might not be able to eat much for the first 3 days after the surgery; then slowly progress on to liquids.
  • A catheter may be attached to your bladder to help you urinate.
  • Medications will be administered to reduce the pain and prevent blood clots.

At times, you may experience pain in your body and frequent mood changes post- surgery. It is recommended to incorporate certain lifestyle changes after the surgery to prevent putting on weight once again.
