What is Gastric Bypass surgery?
Gastric bypass surgery has been tried and tested for over 40 years. It’s a procedure where the stomach is partitioned to a smaller size and the small bowel is re-routed to this new gastric pouch. In the banded gastric bypass, a fixed silastic ring is placed around the gastric pouch.
The gastric bypass can be the traditional Roux en Y gastric bypass or the one anastomosis gastric bypass also known as Omega loop/ mini gastric bypass.
The decision to choose one weight loss surgery over the other depends on various factors including the presence of reflux, previous surgery etc. The Roux en Y gastric bypass has been around for a long time and has good data of long-term outcomes as compared to the Mini gastric bypass.
Advantages
- Long-standing information and results
- 80 to 90% excess weight loss
- Up to 90% diabetes control
- Good control of reflux
Disadvantages
- Risk of ulcer in the anastomosis
- Dumping syndrome
- Internal hernia risk
More Information
Gastric Bypass surgery is a procedure that involves partitioning the stomach into a smaller section (termed gastric pouch). A gastric bypass can reduce the volume of the stomach by up to 90%, reducing a typical ‘holding’ capacity of a 1000ml stomach to just 100ml. The small intestine is then divided and re-connected to this segment. It is a procedure that is regularly performed by Mr. Gounder.
The result of this procedure is that feelings of satiety, or ‘feeling full’ occur after much less food is consumed by the patient as well as reduced absorption of ingested food.
This occurs because the smaller ‘segmented’ pouch ‘fills’ up much faster than the original stomach and rapid entry of nutrients produces gut hormone changes that prompts the brain to ‘think’ the patient is in fact full after eating a significantly smaller portion of food.
As with most bariatric procedures, these are recommended for patients with a high BMI, typically over 35 (you can check your BMI here) but it is imperative you book a consultation with your weight loss surgeon, Mr Siva Gounder to determine what course of bariatric surgery is best suited to you.
