About Gastric Bypass Surgery

Gastric bypass is a surgery that helps a person lose weight by changing how the stomach and small intestine handle the food a patient eats. The food a patient eat will no longer go into some parts of the stomach and small intestine that absorb food. Because of this, the body will not get all of the calories from the food we eat.


Symptoms for Detecting Gastric bypass

  • If you have a BMI higher than 35

  • If you are suffering from other complications like diabetes, hypertension, sleep apnea, etc.

  • In case your weight is increasing steadily causing other metabolic disorders

  • If you are gaining weight even after restrictive diet


Medical Tests/ Diagnosis for  Gastric bypass

Some tests are required to ascertain the success of Gastric Bypass. The important tests are:

  • A complete Blood Count

  • Urinalysis and a Chemistry Panel

  • Chest X-Ray and Electrocardiogram


Some Surgeons may also ask you to get the following tests on the basis of your medical history:

  • Gallbladder Ultrasound to look for gallstones

  • Pulmonary Function Test

  • Echocardiogram

  • GI Evaluation

  • Cardiology Evaluation

  • Psychiatric Evaluation

  • Sleep Studies


Treatment / Procedure for Gastric Bypass

Gastric Bypass is one of the most successful Bariatric procedures for weight loss. It has a very high success rate and the patients have been able to lose up to 70% of their excess weight and maintain it for a period of ten years or longer without significant increase in the weight. It is also the easiest procedure to live with as it does not put added restriction on the food choices, diet plan, etc.

The procedure will be carried out while the patient is on general anesthesia. For laparoscopic surgery only 5-6 small incisions will be made and in case of open surgery the doctor will make a surgical cut to open your stomach.

Gastric Bypass surgery can be broadly divided into two parts. First of all the surgeon will divide your stomach into two parts. The larger part of your stomach will be stapled out and only a small portion of the stomach in form of a pouch will be left for use. The pouch is usually kept very small so that the patients can only consume very small quantities of food and hence the calorie intake reduces considerably. Losing weight through this method becomes easier for the patients as they will start feeling fuller even after eating small portions of food. The urge to eat will also go down significantly.

The second part of the procedure is bypassing where the surgeon will divide the lower part of your small intestine and join it with a hole made in your pouch. Now the food will go directly to this intestine. It will create a Y section of your small intestine and the food will not pass through the complete digestive system. This leads to lower consumption of calories and hence you can lose weight faster. The deficiency of nutrients, vitamins and other minerals is later on supplemented by added intake and hence you can lead a healthy life and lose weight rapidly. This is a ‘malabsorptive’ procedure as absorption of the nutrients is restricted by the surgery. After the procedure not only the patient’s urge to eat more and more will go down considerably but the patient’s body will also not be able to absorb all the calories from the food adding up to the weight making the procedure a great success.

The patient’s stay in the hospital need not be very long and generally the patients are discharged within 2-3 days of the surgery.

The patient may take a week more to get mobile post discharge from the hospital.

Within a month the patient can resume normal life activities in case of laparoscopic surgeries and if the patient had open surgery then the recuperating time may increase to 12 weeks.

After the procedure

The hospital stay in case of Gastric Bypass is short ranging from 2-4 days and the complete recovery may take from 1-3 months depending upon the type of surgery performed i.e. laparoscopic surgery or open surgery. The patient will be kept on liquid diet initially and brought to solid foods over a period of time. The procedure is very safe and effective for rapid weight loss as the body’s ability to absorb calories and nutrients from the food is restricted significantly. In general this surgery has one of the highest success rates and the patients undergoing Gastric Bypass can not only easily lose up to 70% of their excess weight but also maintain it for very long period of time. Almost all kinds of foods are well tolerated by the patients undergoing this surgery however, the patient should always stay away from sweets as it can cause dumping syndrome meaning the patients can get diarrhea , dizziness, light headedness, etc. if they consume too much sweets.
