Which of the following is a common symptom of a peptic ulcer?

Nausea is a common symptom of a peptic ulcer due to the irritation and inflammation of the stomach lining or the duodenum, which can disrupt normal digestive processes. When the ulcer is present, it can cause discomfort and lead to feelings of nausea, especially following meals when stomach acid is being produced. The body's response to this irritation can trigger nausea as a protective mechanism, making this symptom particularly relevant in the context of peptic ulcers.

Other symptoms often accompany peptic ulcers, such as abdominal pain, bloating, or loss of appetite, but nausea is a key indicator that aligns well with the underlying gastrointestinal disturbances caused by the ulcer.
