What is indigestion?

Indigestion, also known as dyspepsia, is a painful or burning feeling in the upper abdomen and is usually accompanied by nausea, bloating or gas, a feeling of fullness, and, sometimes, vomiting. While indigestion may be the result of a disease or an ulcer in the digestive tract, most often it is the result of eating too much, eating too quickly, eating high-fat foods, or eating during stressful situations.

What causes indigestion?

Some causes of indigestion may include the following:

  • stomach or duodenal ulcers
  • stomach irritation (gastritis)
  • regurgitation or reflux of acid from the stomach
  • inflammation of the gallbladder (cholecystitis)
  • lactose intolerance (inability to digest lactose, a milk sugar, and dairy products)
  • irritable bowel syndrome and other disorders affecting intestinal motility
  • swallowing air (aerophagia)
  • anxiety or depression
  • medications that irritate the stomach lining
  • smoking
  • drinking too much alcohol
Treatment for indigestion:

Specific treatment for indigestion will be determined by your physician based on:

  • your age, overall health, and medical history
  • extent of the condition
  • your tolerance of specific medicines, procedures, or therapies
  • expectations for the course of the condition
  • your opinion or preference
  • medications such as antacids, H2 receptor antagonists, proton pump inhibitors, antibiotics, and prokinetics

Avoiding foods and situations that can cause indigestion is one of the most successful ways to treat the problem. While many persons feel antacids may help, indigestion is not the result of stomach acid, so these are not an appropriate treatment. Smokers may be advised to quit smoking or avoid smoking before meals. Also, exercising after a meal can be a cause of indigestion, so scheduling exercise before a meal, or waiting at least an hour after eating, can also help prevent indigestion.

If indigestion is caused by stomach movement problems in the digestive system, medications that treat this may be prescribed.
