Causes
Most of the time, indigestion is not a sign of a serious health problem unless it occurs with other symptoms. These may include:
- Bleeding
- Trouble swallowing
- Weight loss
- Recurrent nausea and vomiting
Rarely, the discomfort of a heart attack is mistaken for indigestion.
Indigestion may be triggered by:
- Drinking too many caffeinated beverages
- Drinking too much alcohol
- Eating spicy, fatty, or greasy foods
- Eating too much (overeating)
- Eating too fast
- Eating high-fiber foods
- Smoking or chewing tobacco
- Stress or being nervous
Other causes of indigestion are:
- Gallstones
- Gastritis (when the lining of the stomach becomes inflamed or swollen)
- Esophagitis (inflamed esophagus)
- Swelling of the pancreas (pancreatitis)
- Ulcers (stomach or intestinal ulcer)
- Use of certain medicines such as antibiotics, aspirin, and nonsteroidal anti-inflammatory drugs (NSAIDs, such as ibuprofen or naproxen)
Definition
Indigestion (dyspepsia) is a mild discomfort in the upper belly or abdomen. It often occurs during or right after eating. It may feel like:
- Heat, burning, or pain in the area between the navel and the lower part of the breastbone
- Unpleasant fullness that starts soon after a meal begins or when the meal is over
Bloating and nausea are less common symptoms.
Indigestion is NOT the same as heartburn.
