Gastric bypass surgery helps to lose weight by changing how the stomach and small intestine handle the food we eat.
The stomach becomes smaller after the surgery and we feel full with less food.
The food we eat gets absorbed in the small intestine instead of getting into parts of the stomach and small intestine. Hence, the body doesn’t get all of the calories from the food we eat.
Patients are administered general anesthesia before this surgery to fall asleep and pain-free.
The first step of the surgery is to make the stomach smaller. The stomach is divided into a small upper section and a larger bottom section using staples. The stomach pouch or the top section of the stomach is where the food goes as we eat. This pouch is ideally of the size of a walnut and can hold nearly 1 ounce (oz) or 28 grams (g) of food. Thus, we eat less and lose weight.
The next step is the bypass. In this step, the surgeon connects a small part of the small intestine, also known as the jejunum, to a small hole in the stomach pouch. Thus, the food now travels from the pouch into this new opening and finally into the small intestine. This ultimately results in absorbing lesser calories in each meal.
Gastric bypass can be done with open surgery or laparoscopy. In the open surgery, the surgeon makes a large surgical cut to open the belly first. Next step is the bypass on the stomach, small intestine, and other organs.
Laparoscopy uses a tiny camera (laparoscope) that enables the surgeon to see inside the belly.
In a laparoscopic gastric bypass, the surgeon makes 4 to 6 small cuts in the belly and inserts the scope and instruments through these cuts.
The laparoscope is connected to a video monitor present in the operating room that shows the view inside the belly during the operation.
The surgery takes nearly 2 to 4 hours.
