Changes After Bariatric Surgery
Hi,
I am Dr. Ramen Goel.Today I am going to share with you the current information that it is the physiological changes that happens after bariatric surgery which are responsible for weight loss. Typically we believed that after surgery because the stomach is small, there is restriction on food intake and weight loss happens. But research in last 5-10 years have established that it is not the restriction of the food intake but it is the physiological changes which includes changes in Ghrelin hormone, changes in GLP-1 hormone, changes in the bacterial which are present in the gut, changes in the bile acid levels in the blood. All these together are responsible for physiological changes and that helps in weight loss.
Now look at the scenarios, if someone gets pregnant in 2 months after surgery, then the person will gain weight, they will not lose weight. So if only the stomach size was responsible for weight loss this lady cannot gain weight. So the physiology of pregnancy is much stronger than the surgery and that's why the current concept says that just by restricting the food intake you cannot lose weight. It is a physiology, biology which changes the body. Its a great information because at no stage with diet manipulation you can lose as much weight as with surgery because the physiological changes do not happen after dietary regulation.
