What are the most common symptoms of stomach ulcers?

Burning pain anywhere from the navel to the breastbone is a common symptom of ulcers, Mayo Clinic writes. An empty stomach often aggravates the pain due to acid coming into contact with the ulcerated area.

It is common for ulcer pain to be especially acute at night, Mayo Clinic notes. Acid-reducing medication often alleviates the pain only temporarily.

Less common symptoms of stomach ulcers include the vomiting of blood, which sometimes appears black, and the presence of dark blood in stools. Nausea can also be a sign of an ulcer, says Mayo Clinic.

Finally, unexplained weight loss and changes in appetite are occasionally symptoms of ulcers, Mayo Clinic adds.
