Gastric bypass is a kind of bariatric surgery, which helps in weight loss. This surgery aims to make changes so that your stomach becomes smaller than it used to be. This limits the amount of food you consume and effectively helps you to reduce weight.
Are you fit for the surgery?
Not everybody can go in for this surgery. Your doctor will recommend this surgery after careful evaluation. These are the parameters based on which your doctor will make a decision-
• Your medical history - If you suffer from sleep apnoea, heart ailments, liver diseases, kidney stones or if you have blood clots then you might have to undergo the surgery.
• Your psychological status - Sometimes obesity is the outcome of certain psychological ailments. A doctor will first ensure that these conditions are addressed before you go under the knife.
How is the surgery performed?
Gastric bypass operation is performed under general anaesthesia so you will be asleep for the entire duration of the surgery and it will be pain-free. The surgery is done laparoscopically. Tiny incisions are made through which scope and fine surgical instruments are introduced into the abdominal cavity. The camera guides the surgeon by providing live images from inside the body. Laparoscopic gastric surgery is advantageous because the wound heals faster and does not leave any marks.
Sometimes your surgeon might opt for an open surgery where she/he makes a large incision to reach the stomach.
There are two major steps to the surgery-
• The aim of the surgery is to make the stomach smaller so the surgeon divides it into two portions with staples. The food that you eat will go into the upper part (the pouch) of the stomach. The reduced upper stomach can hold at the most 28 grams of food so you are forced to eat less than usual. This will help you lose weight.
• The other step is the bypass surgery. After the pouch is created, the surgeon links it to the small intestine through the small hole in the pouch. This way, food will pass directly from the pouch to the small intestine. The surgery takes around 3-4 hours. You will be kept under observation for a couple of days and you will be released from the hospital in a week.
Gastric bypass operation is an effective and simple surgery that can help you reach your weight goals when you have a very high BMI and most other dietary restrictions have not been successful.
