Mini gastric bypass is a surgery for morbidly obese but less invasive than a classic gastric bypass. 

The stomach is sectioned in the form of a narrow tube and attached to the small intestine,approximately 2500 cms. from the initial point of small intestine. The mechanism of action is in three different ways:

• Restriction the food amount in the stomach
• Malabsorption since a large part of initial small intestine is bypassed decreasing calorie absorption.
• Hormonal levels of ghrelin or hunger hormone is reduced by bypass decreasing appetite. 

• It is a reversible procedure
• Recovery time is less than standard gastric bypass surgery
• Better Relief from symptoms associated with obesity after the weight sheds off
• Lower risk of post-surgery complications.
• Lower risk of infection because of minimal incisions required
• Rapid healing of incisions so the patient can resume regular activities shortly after the procedure

The main criteria for undergoing Mini gastric bypass surgery is that you should have a BMI of 40 and above, or 30 and above with presence of other co-morbidities like diabetes, sleep apnea, joints pain etc. You should have tried a diet and exercise programme in the past and failed to have achieved weight loss, there should no other history of weight loss surgeries and alcohol abuse and if you are between 16 to 65 years of age, you can undergo mini gastric bypass surgery. 

The procedure is performed laparoscopically under general anaesthesia. An access is created to the abdominal cavity with small incisions of approximately 1 inch for instrument insertion. The liver is retracted for the procedure. The stomach anatomy is then divided into two portions. The surgeon makes a narrow stomach tube that is connected to the distal end of small intestine at a distance aprox. of 250 centimeters The second distal section of stomach that does not receive food for digestion juices flow down to reach the digesting food at distal end.

Recovery is quick with laparoscopic procedures. You will need to stay for 2 nights at the hospital for recovery. Follow-up visit is done for confirmation of an uncomplicated recovery. After surgery a proper diet, exercise and lifestyle changes have to be accommodated for desired weight loss and to sustain the results. 

According to several studies done in the past the short term, weight loss is approximately 70 – 85%. In most of these cases, at least 60 % of weight loss is sustained over long term.
