Indigestion, also called dyspepsia, is a condition that occurs when the normal process of digestion is disturbed. The symptoms of indigestion include nausea, vomiting, bloating, gas, and heartburn, which is a burning sensation in the chest. Stomach cramps, belching, and a feeling of fullness sometimes accompany these symptoms.
In most cases, indigestion is caused by poor eating habits, such as eating too much or too quickly, swallowing air while eating, and not chewing food properly. Sometimes it may result from eating excessive amounts of fatty foods, improperly cooked foods, or certain vegetables, such as cabbage, onions, and radishes. It may also be caused by emotional upsets and by diseases of the stomach and gallbladder. Indigestion can often be prevented by the establishment of good eating habits and by the avoidance of foods that bring on the condition. When caused by disease, indigestion can be relieved only by treatment of the disease. Persistent or severe indigestion or the sudden onset of indigestion in a person who never before had digestive problems should be checked by a physician.
