When individuals hear discussion about the lap band or gastric bypass as a solution for obesity, they often question whether or not a smaller stomach will truly make a difference in the way the person eats. Would the person just overeat anyway and eventually stretch out the stomach again? Formulate an argument against this notion.

What will be an ideal response?


In the case of gastric surgical interventions, the levels of ghrelin are disrupted. Ghrelin causes increased eating, but, here, ghrelin is reduced. In addition, PYY levels increase, which increases feelings of satiety. The reasons why these substances differ are not well understood. It is thought that the communication between the stomach and the intestines is disrupted, impacting ghrelin. As food likely moves more slowly through the digestive tract, this may explain the increase in PYY.
