Question: what happens when you throw up after you eat?
Answer: Damage to your esophagus. Forceful vomiting can cause tearing of the lining of your esophagus, the tube that connects your throat to your stomach. If it tears, it can cause severe and life-threatening bleeding. This is known as Mallory-Weiss syndrome. Bright red blood in your vomit is a symptom of this syndrome.
