Gastric Bypass


Gastric Bypass Surgery, also known as Roux-en-y gastric bypass, is a kind of bariatric surgery that is a combined with sleeve gastrectomy. It is one of the major weight loss surgeries that can help you lose up to 55-70% of your excess weight.

It works by seperating the upper part of the stomach pouch from the rest. Then immediately diverting it to the part of your small intestine so the food will only go to the upper section of the stomach. Thus, when the patient eats a small portion of food, he will immediately feel full as if his stomach was filled with plenty of food. This procedure takes between 2-4 hours.

The most essential condition a patient must meet to have the surgery is to have the suitable Body Mass Index (BMI). The eligible BMI for the surgery is 35 or higher.  For the eligible patient, Gastric Bypass Surgery can treat many disorders apart from obesity, such as sleep apnea, heart disease, high cholesterol and blood pressure and many more.

Therefore, your surgeon will prescribe some vitamins and immune system supporter supplements. You may need to use these vitamins and supplements for a long time period.

The Gastric Bypass Operation has three main stages:

  • Anesthesia stage: At this stage, the patient is given general anesthesia to protect the patient from feeling any pain during the operation.
  • Sleeve gastrostomy stage: At this stage, the doctor sleeves the upper section of the stomach, which is a small stomach pouch section that can accommodate up to 28 grams of the food. Thus, the food will go directly, without passing by the larger lower section forcing the patient only to eat small amounts of food.
  • Gastric transformation stage: At this stage, the doctor connects the upper part of the stomach directly to the small intestine through a small hole to allow the food to pass to the small intestine.
