Nowadays, weight management is the biggest problem for people from all age groups. Weight loss surgery options are preferred when alternative means of weight loss such as exercise, diet management, and so on fail to work.

Gastric bypass, also known as Roux-en-Y Gastric Bypass, is one of the most popular weight loss surgery options during which the size of the stomach is decreased. The reduced size of the stomach allows for reduced consumption of food by the patient, which in turn, results in gradual weight loss.

Other popular weight loss surgery options include:

  • Sleeve gastrectomy
  • Adjustable gastric band
  • Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

Of all the bariatric procedures, gastric bypass is the most preferred options for weight loss because of the greater possibility of positive outcomes. Moreover, there are no major side effects of gastric bypass.

 What are the criteria for gastric bypass surgery?

 Not everyone is an ideal candidate for gastric bypass surgery. People with a body mass index (BMI) of 40 or more and with a history of heart disease, obesity, and obstructive sleep apnea are mostly recommended gastric bypass surgery.

Before the Treatment

Before a Month of the Surgery

  • A few diagnostic tests, including blood tests and an ultrasound scan of the stomach, are performed almost a month before the surgery to make sure that there are no risks involved and the condition of the patient is perfect for gastric bypass surgery.
  • The patient should gather all the possible information about the risks involved, changes to be made, and the extent of weight loss they are likely to experience.
  • The patient should inform the physician about their usage of specific over-the-counter or herbal medicines, smoking habits, or if she is pregnant or planning a pregnancy.


During the Week of the Surgery

  • The patient stops taking aspirin-like medicines
  • The physician informs the patient which medicines can be taken until the day of the surgery


Right Before the Surgery

  • The patient should completely avoid taking food and water hours before the surgery
  • The patient takes medicines advised by the physician with a small sip of water

How it is Performed

Gastric bypass surgery is performed in two phases:

Phase I

  • A small part of the stomach, of about 30 millilitres to 1 ounce in volume, is cut.
  • This is done to form a gastric pouch, where the food will go after eating once the patient is done with the surgery.

 Phase II: Bypass

  • The upper part of the small intestine is cut in the middle. The lower part of the small intestine, jejunum, is now attached to the gastric pouch.
  • The upper part of the small intestine is also attached to the jejunum. This facilitates the mixing of stomach acids and digestive enzymes from the stomach pouch and the upper portion of the small intestine with the food. This allows for normal digestion.


  • 1-4 days of hospital stay may be required
  • Pain medications and medicines to prevent blood clots is administered after the surgery
  • The patient is able to eat normally only after 3 days of the surgery
  • Special stockings to prevent formation of blood clots in the legs will be advised
  • The patient should follow diet and exercise as suggested by the physician and the dietitian

    There is a significant weight loss in the first month after the surgery, which gradually decreases. To maintain the intensity of weight loss, the patient must follow a strict exercise routine and diet.

    The following medical conditions usually improve after gastric bypass surgery:

    • Asthma
    • High blood pressure
    • High cholesterol
    • Type 2 diabetes
    • Obstructive sleep apnea

Q. Is the gastric bypass surgery reversible?

A. Reversal of the procedure is possible, but it is rarely recommended.

Q. Can the surgery be repeated?

A. Gastric bypass can be repeated in some patients. But it is not preferred due to the risk of scarring. Many patients prefer other weight loss surgery options rather than opting for a second gastric bypass surgery.

Q. Will the surgery cure diabetes or obesity-related illnesses?

A. The illnesses will not be reversed because of the surgery alone. But gastric bypass surgery definitely helps reduce the effect of obesity-related illness and may improve the condition of the patient considerably if a strict diet and exercise routine is followed.

Q. What should be done if the patient develops excess skin due to weight loss?

A. A significant amount of weight loss can lead to excess skin, which tightens over a period of time. The excess skin can also be removed or tightened with the help of plastic surgery.
