Peptic Ulcer
A peptic ulcer occurs when there is an open sore in the esophagus, small intestine, or stomach. It can be caused when the gastrointestinal tract loses a part of the protective lining. People with peptic ulcers might have bleeding and pain. Drinking alcohol moderately will not lead to this health issue. However, excessive consumption can be a major risk factor as alcoholic beverages would damage and irritate your stomach’s lining. Typical symptoms include bloating, nausea, heartburn, indigestion, burning abdominal pain, and stomach pain. In more serious cases, these ulcers could perforate the gastrointestinal lining and result in bleeding. That’s why you might throw up blood after drinking. [5]
