From the first time you purge. You are depriving your body of vitamins and nutrition. You risk burning the lining of your esophagus, and the inside of your mouth. Damage to teeth from stomach acid is a common problem. There is also the risk of asperating acid and acid fumes into your lungs. That's just the starting point. The above is true and I'd just like to add the stomach is a muscle so if you keep purging your stomach will eventually refuse food and vomit it up. You could die!
