This seems to be a topic that comes up often so I will try to explain all of them and how they happen. Over eating causes your 2-4 ounce pouch to stretch and force food up into your esophagus causing it to dilate. Just because people think that food does not stay in the pouch long that is not true as you get tighter. The food takes longer to go down and eating fast or over eating causes pouch stretching. Band erosion is also caused from over eating. Imagine your band around your stomach and every time you over eat you are forcing your band into the stomach wall. Over a period of time your stomach tissue will wear away and your band will erode into your stomach causing your stomach contents to go into your abdominal cavity which is poison to your system. If you feel like food is backing up into your throat then you are over eating. I know some people eat a cup of food but if you look at most pictures of the band and ask your doctor how much food will my pouch hold not how big is my band, I am sure they will tell you 4 ounces which is a half cup of food. Now the cup to half cup can be debated all day long but the fact is if you over eat which ever that means for you, you are risking your pouch to stretch, dilate your esophagus (which will cause problems pushing the food down) and band erosion.

Take your time to eat, don't over eat and take care of your band and yourself so that it can last a long time. Also being too tight can add to much pressure to the band and cause it to erode also. So make wise choices when eating and getting fills.
