If you are having a hard time losing weight despite all of the hard exercises and diet programs recommended to you, you definitely need a medical intervention in order to achieve your goal. One of the wonders that modern medicine has produced is a type of surgery that alters the interaction of food and a person’s digestive system. This particular surgery is called gastric bypass surgery and it helped millions of obese patients worldwide.

What is Gastric Bypass?


Gastric bypass is a kind of surgery that aims to change how a person’s stomach and small intestine handle the food that a person eats. This medical procedure is intended for obese people who are having a hard time losing weight. There are two steps involving this process:

  1. The surgeon will use staples to divide the stomach into a small upper part and a larger bottom portion. The upper portion becomes what we call the pouch. This portion will be just the size of a walnut and is where the food will go. After the surgery, the stomach will be smaller and it will only be able to store a small amount of food that will be digested in the intestines.
  2. The next step is the bypass. The surgeon will connect the jejunum or a part of the small intestine to the small hole into the pouch. The food will now transit from the pouch straight into the small intestine, resulting in less calorie absorption.

Gastric bypass is a long and invasive surgical procedure that involves cutting up a person’s intestine. There are two methods of operation that will be presented to a patient. These are:


  • Open surgery. This gives the surgeons access to your digestive track. This is faster because the doctors will be able to see the condition of your digestive track firsthand and do the surgery without obstruction. However, this will leave a huge scar in your midsection. The recovery period is usually five to eight weeks.
  • Laparoscopic surgery. This surgery is done by inserting the surgical instruments inside the body. The whole process is then monitored using a camera inside the instruments. The laparoscopic procedure yields fewer scars but it is done slower because the surgeons won’t have easy access to the digestive track especially if the patient is rather large in size. Since the entry wounds from laparoscopic surgery are smaller compared to open surgery, the recovery period is three to six weeks.



Gastric bypass procedure is proven beneficial to obese people who are getting little results in their diet-and-exercise weight loss regimen. This procedure is normally irreversible, that’s why before deciding to have this surgery, a complete medical assessment.
