Indigestion is very common.
Doctors do not understand why most people get indigestion. In patients who seek medical help for their indigestion, about one patient in six has a peptic ulcer. Stomach cancer is rare, and is especially rare before the age of sixty. If you smoke, chew tobacco, or use nicotine chewing gum, quit. Smoking is a major cause of dyspepsia and slows the healing of ulcers.
