Many people are trouble with occasional bouts of  indigestion. These episodes arise from a disordered stomach, which is often irritated by improper foods.

Nervous problems are another common cause of gas and indigestion. Such symptoms are often present all through life. But if a person suddenly notices he has indigestion more frequently, it is high time to see his doctor and have an X-ray of this stomach and bowel. Cancer may be lurking within.
