Obesity is an epidemic that greatly affects over 50% of the American population. The reasons for this epidemic are numerous, from the growing trend of the super-sized meal to the intense laziness of the average American.

These changes cause the patient to feel full more quickly than when the stomach was its original size, which reduces the amount of food, and in turn calories, that the patient consumes. In normal digestion, food passes through the stomach and enters the small intestine, where many of the fatty calories and nutrients are absorbed into the bloodstream.
