Mini Gastric Bypass
Mini Gastric Bypass is one of the most effective type of bariatric surgery that produces excellent weight losss. It is a simple, straightforward, operation. This procedure is therefore gaining recognition and popularity as a weight loss procedure.
Mini gastric Bypass is a combined type of procedure having both restrictive and malabsorptive components. However, in this procedure restriction is less as the stomach pouch is longer thereby giving patient the freedom to eat more amount of food. The length of intestine bypassed is more as compared to gastric bypass so more of malabsorption takes place.
How Mini Gastric Bypass works
Creating a small tube of stomach ensures limited amount of food can be taken
Bypassing a portion of the small intestine (between 150-300cm long) results in fewer calories being absorbed, thus creating additional weight loss.
Reduced levels of ghrelin cause decreased appetite and early satiety.
Hormonal changes enhance the metabolism of glucose thus causing resolution of diabetes and other obesity related health problems.

How mini gastric bypass is done?
This procedure is done through laparoscopic or key hole surgery and involves making 4-5 tiny holes on the abdomen. The incisions are usually 5mm-1cm in size. The whole procedure takes about 30-40 minute.
How long is the hospital stay after mini gastric bypass?
Patient is usually discharged 24-48 hours after the surgery. Patients start taking liquid diet shortly after the surgery, sometimes as early as few minutes, depending upon their level of consciousness and comfort.
When does patient start walking after the surgery?
Usually within few hours of surgery patients are mobilized and next morning of surgery, patients are able to able to walk comfortably in their room.
What is diet after Mini Gastric Bypass Surgery?
Patients start taking liquid diet on the day of surgery and gradually switch to soft and solid diets within days of surgery. As mini gastric bypass is more of a malabsorptive procedure, patients are encouraged to have high protein diet.
Non-Vegetarian patients can have high proteins from fish, egg and chicken, whereas vegetarian patients can have high proteins from tofu cheese, soya milk, cereals and soybean etc.
We usually encourage our patients to take Mediterranean diet like salads, eating primarily plant-based foods, such as fruits and vegetables, whole grains, legumes and nuts and replacing butter with healthy fats, such as olive oil, using herbs and spices instead of salt to flavor foods should be emphasized.
What diet should be avoided after Mini Gastric Bypass?
Diet high in carbohydrate, sugar and fats should be avoided for eg. fizzy or carbonated drinks, fried food etc. In fact, one should try to adhere the dietary guidelines and dietary chart prepared by nutritionists.We, at our centre, take special care to ensure a customized diet chart to every patient depending upon their dietary preferences.
When can one start the normal routine work?
4-5 days after the surgery, light jobs can be started, which include office jobs. The jobs which require physical strength can be started 10 days after the surgery. However, majority of our patients are able to join back their work in a weeks time.
After how long a patient can exercise?
We encourage all our patients to walk around within hours of surgery. The morning after surgery, we expect our patient to walk around relatively comfortably. On discharge from hospital, we ensure increasing activity levels on a daily basis including longer and longer walks under the guidance of our physiotherapists. More active exercise such as at the gym can be introduced one week after surgery, with a gentle reintroduction to aerobic exercise such as light jogging, cycling or swimming. Exercise involving heavy weight can be started one month.
