What should you know about chronic heartburn causes?

Heartburn occurs when acidic stomach contents travel into the oesophagus and irritate its lining. A hiatus hernia can make this movement easier, while increased abdominal pressure, including that associated with obesity, may add strain. Gastritis and peptic ulcer disease can cause upper abdominal burning that feels similar. Symptoms alone cannot identify the cause, so the timing and accompanying features matter.

Keep a short symptom diary covering meals, posture, bedtime, alcohol, smoking, and medicines such as anti-inflammatory painkillers. Smaller meals, staying upright after eating, and avoiding personal triggers may reduce episodes. Ask a pharmacist or doctor whether acid reflux medication is appropriate; check before changing regular medicines or using supplements. Ongoing symptoms deserve a planned assessment.

Seek prompt medical advice for heartburn that is persistent, worsening, or accompanied by difficulty swallowing, repeated vomiting, unexplained weight loss, black stools, or marked weakness. Get emergency help for crushing chest pressure, faintness, sweating, or breathlessness, as a heart problem may resemble heartburn.

Ask which causes fit your pattern and whether your medicines could contribute. Discuss whether you need testing, how long to use treatment, and which symptoms should trigger an earlier review.
