Indigestion side effects: what to know

Common symptoms include feeling full quickly, bloating, burping, nausea, an acidic taste, or burning behind the breastbone. Symptoms may follow meals or become more noticeable when lying down. Reflux, gastritis, a hiatus hernia, peptic ulcer, or Helicobacter pylori infection can present with this pattern. Gallstones can cause upper-abdominal pain and nausea, particularly after meals. These symptoms overlap, so their timing, severity, and duration matter more than one symptom alone.

Try smaller meals, eat at a relaxed pace, and remain upright after eating. Limit foods and drinks that clearly trigger symptoms, such as rich meals, alcohol, caffeine, or spicy foods. Review regular medicines with a pharmacist or clinician because some painkillers can irritate the stomach. A pharmacist can advise about an antacid or acid reflux medication, including how it fits with your other medicines. Record symptoms and triggers for your appointment.

Get emergency help for chest pressure, difficulty breathing, fainting, vomiting blood, or black stools. Seek prompt assessment for repeated vomiting, trouble swallowing, severe pain, fever, yellow skin or eyes, or unexplained weight loss. Book a medical review when symptoms persist, frequently return, or change from your usual pattern.

Ask whether your symptoms fit reflux, stomach irritation, gallstones, or another cause. Discuss whether Helicobacter pylori testing is suitable, whether a medicine may be contributing, and what changes should prompt urgent review.
