What are the symptoms of indigestion?

The main symptoms of indigestion include: 1. Postprandial discomfort: A feeling of fullness after meals, with food seeming to remain in the stomach for a prolonged period, causing bloating, belching, and other symptoms. 2. Upper abdominal pain: Characterized by dull pain, distension pain, or a burning sensation. The pain is irregular in timing and may worsen after meals, with variable duration. 3. Changes in appetite: Due to difficulty in digesting food, patients may experience loss of appetite or even aversion to food, along with a prolonged absence of hunger. 4. General symptoms: Some patients may experience systemic symptoms such as palpitations, headache, insomnia, acid regurgitation, and heartburn. In severe cases, symptoms such as nausea, vomiting, and diarrhea may also occur. 5. Psychological impact: Long-term indigestion may lead to emotional disturbances, such as anxiety and depression, further affecting the patient's quality of life.
