The primary cause of peptic ulcers is usually Helicobacter pylori infection, though other factors can also trigger the onset of peptic ulcers, such as tobacco and alcohol irritation, poor dietary habits, and emotional issues. Additionally, excessive fatigue is also one of the causes that can trigger or cause a recurrence of peptic ulcers. Therefore, whether or not a person with peptic ulcers can exercise depends on the specific condition of the illness. If it is an acute active phase or a subacute peptic ulcer that has not fully healed, strict rest is necessary in such cases. If a gastroscopy shows that the ulcer has completely healed, moderate and light activities are permissible, but excessive fatigue should still be avoided.
