How can bariatric surgery help me lose weight?

Bariatric surgery can help you lose weight in part by resetting your metabolism, unlike strict dieting alone. The same amount of oral intake without bariatric surgery will leave you feeling hungry whereas with bariatric surgery your stomach and your mind feel satisfied.
Bariatric surgery can help you lose weight by creating changes in the body that allow you to lose more weight than you would be able to lose on your own. More importantly, these changes also help you keep the weight off longer than standard dieting. Some of these changes involve hormones and some involve the way your body adapts to weight loss.People who have bariatric surgery still must create a healthier lifestyle by eating better, exercising regularly and becoming a more conscious eater, like we all need to do!
How bariatric surgery can help you lose weight is not completely understood in terms of weight loss or how surgery improves or resolves obesity-related illnesses. Traditionally it has been accepted that bariatric surgery worked by calorie restriction, lack of absorption of nutrients, or a combination of the two. But it is now known that numerous metabolic, hormonal and behavioral changes take place after weight loss, suggesting a more multifactorial and complexed mechanism is likely involved.

Bariatric (weight loss) surgery is just one tool to help you achieve your health and weight loss goals. In this video, surgeon Sebastian Tas, DO, of Largo Medical Center, describes the resources that accompany bariatric surgery.
Bariatric surgery procedures for weight loss are either restrictive and/or malabsorptive: they restrict the intake of food and/or cause some of the food to be poorly digested and absorbed, and therefore eliminated in the stool. Gastric banding and sleeve gastrectomy are "restrictive" surgeries, whereas the Roux-en-Y gastric bypass, banded gastric bypass, and duodenal switch are "combination" type procedures resulting in both a restrictive and malabsorptive effect.

In surgery for obesity management your stomach is divided into two portions: the small portion is your new stomach, or reservoir for food. As you eat, the food enters your pouch and empties slowly. Since your stomach pouch is very small, you will feel full very quickly. Overeating can be very uncomfortable and may result in vomiting. Your eating habits will therefore change drastically and you will likely never be able to eat the quantity of food that you can currently eat. For example, a typical size lunch for most patients is half a sandwich and a piece of fruit.

In addition, after gastric bypass surgery, most patients develop a phenomenon called "dumping syndrome." When sweets are eaten the patient experiences sweating, fatigue, lightheadedness, and diarrhea. This unpleasant experience helps patients avoid sweets, and many patients report losing their desire to indulge in sweets. Furthermore, eating large amounts of fats may lead to poor absorption and result in diarrhea and abdominal cramping.
