Do ulcers cause a bloody cough?

Ulcers, specifically peptic ulcers, typically do not cause a bloody cough directly. However, if an ulcer leads to complications such as bleeding, and the blood enters the gastrointestinal tract, it can be vomited or potentially aspirated into the lungs, resulting in a bloody cough. Conditions like esophageal varices or severe gastric bleeding are more commonly associated with coughing up blood. If someone is experiencing a bloody cough, they should seek medical attention promptly.
