Indigestion Indigestion is more common in middle-aged people, after eating heavy meals and is often worse at night. Regurgitation or reflux is painful although rarely dangerous. Stomach acid escapes into the gullet, causing chest pain. It can be mistaken for a heart attack. Severe reflux can occur with a hiatus hernia. Symptoms A vague pain below the ribcage, extending into the throat. An acid taste in the mouth. Too much wind. Causes Eating a heavy meal or drinking alcohol. 'Rich' food, that often contains a lot of fat. Smoking too much. A leaking valve at the neck of the stomach (hiatus hernia). Prevention Avoid food which you know can bring on an attack. Sleep with your upper body propped up with pillows. Avoid eating just before bedtime. Eat small meals more often. Avoid aspirin and drugs like ibuprofen (non-steroidal anti-inflammatory drugs). Complications Most indigestion is harmless but annoying. The acid refluxing into the throat does not appear to cause any serious damage. The greatest danger is ignoring repeated attacks or confusing them with a heart attack. Get medical advice if your symptoms won't go away or if they get worse. Self care Your pharmacist will advise about indigestion remedies (antacids and other medicines). Avoid taking large amounts of sodium bicarbonate (bicarbonate of soda) as this is turned into salt in the body. A glass of milk before bed can help. Close this window.
