How does bulimia affect the esophagus?
The stomach acid (hydrochloric acid) that breaks down your food is extremely powerful, so, constant vomiting will wear away the lining of your esophagus. Eventually, you may wear holes in your esophagus, which can be fatal. Even if this doesn't happen, you will most likely have acid reflux for the rest of your life, since all the vomiting weakens your cardiac sphincter, which is basically like the lid of your stomach: it keeps the acid from splashing up into your esophagus. After years of vomiting many times a day, the sphincter constantly flaps open like the lid of a garbage can.
