By Mayo Clinic staffThere are many possible causes of indigestion. Some are related to lifestyle and what you're eating and drinking. Indigestion can also be caused by other digestive conditions.
Common causes include:
- Overeating
- Eating too quickly
- Fatty or greasy foods
- Spicy foods
- Too much caffeine
- Too much alcohol
- Too much chocolate
- Too many carbonated beverages
- Smoking
- Nervousness
- Emotional trauma
- Medications, including antibiotics, aspirin and nonsteroidal anti-inflammatory drugs (NSAIDs)
- Stomach inflammation (gastritis)
- Pancreas inflammation (pancreatitis)
- Peptic ulcers
- Gallstones
- Stomach cancer
When a cause for indigestion can't be found after a thorough evaluation, a person may have functional dyspepsia. Functional dyspepsia is a type of indigestion that may impair the stomach's ability to accept and digest food and then pass that food to the small intestine.
