Indigestion, also known as upset stomach or dyspepsia, is discomfort or a burning feeling in the upper abdomen, often accompanied by nausea, abdominal bloating, belching and sometimes vomiting. Some people also use the term indigestion to describe the symptom of heartburn.
Tips to control heartburn:
- Avoid foods and beverages that affect lower esophageal sphincter pressure or irritate the esophagus lining
- Lose weight if overweight
- Stop smoking
- Elevate the head of the bed six inches
- Avoid lying down two to three hours after eating
- Take an antacid
Indigestion might be caused by a disease in the digestive tract such as ulcer or gastroesophageal reflux disease (GERD), but for many people, it results from eating too much, eating too quickly, eating high-fat foods or eating during stressful situations. Smoking, drinking too much alcohol, using medications that irritate the stomach lining, being tired and having ongoing stress can also cause indigestion or make it worse.
Some people have persistent indigestion that is not related to any of these factors. This type of indigestion — called functional or nonulcer dyspepsia — may be caused by a problem in the muscular-squeezing action of the stomach (motility).
To diagnose indigestion, the doctor might perform tests for problems like ulcers. In the process of diagnosis, a person may have X-rays of the stomach and small intestine or undergo endoscopy, in which the doctor uses an instrument to view the inside of the stomach.
Avoiding the foods and situations that seem to cause indigestion in some cases is the most successful way to treat it. Smokers can help relieve their indigestion by quitting smoking, or at least not smoking right before eating. Exercising with a full stomach may cause indigestion, so scheduling exercise before a meal or at least an hour afterward might help.
To treat indigestion caused by a functional problem in the digestive tract, the doctor may prescribe medicine that affects stomach motility.
Because indigestion can be a sign of, or mimic, a more serious disease, people should see a doctor if they have:
- Vomiting, weight loss or appetite loss
- Black tarry stools or blood in vomit
- Severe pain in the upper right abdomen
- Discomfort unrelated to eating
- Indigestion accompanied by shortness of breath, sweating, or pain radiating to the jaw, neck, or arm
- Symptoms that persist for more than two weeks
Following the tips outlined above can help you manage your indigestion and experience the uncomfortable symptoms less often.
