How does weight loss surgery work?

Ten years ago we would have given you two ways in which surgery works: restriction & malabsorption. However, now we understand that hormonal changes are most likely the significant players. It turns out that the intestines are prolific hormone producing organs, and the way they see the food is very important as to how we store our calories.

Today, our foods are heavily processed. There are not many complex carbohydrates such as starches and complex proteins put into our diet. As a result, digestion is very quick. Think of our modern day processed food as pre-digested. So, there is very little in the way of food particles reaching the end part of our intestines. This is important because when food particles reach the end of the intestines it stimulates the intestines to produce the hormones that stop us from eating anymore by making us feel full.

Bypassing the intestines, for eample as we do with the gastric bypass or removing large portions of the stomach that allow rapid emptying of food allow food to reach the bottom of the intestines quickly, cause a high release of these hormones. This in effect takes away out hunger. It makes sense that weight loss surgery works through a mechanism that removes hunger. Hunger is the real enemy of weight loss.

And that is the short and sweet of how we believe modern-day weight-loss surgeries are most effective at taking the weight off and then keeping it off!
