Gluten and heart palpitations

Palpitations can feel like pounding, fluttering, skipped beats or a racing heart. A meal may coincide with dehydration, caffeine, alcohol, anxiety, poor sleep or a change in blood sugar rather than gluten being the direct cause. Digestive discomfort can also make heartbeat sensations more noticeable.

Clinicians may consider dehydration, hypoglycaemia, anaemia or iron-deficiency anaemia, thyroid overactivity and anxiety. They may also check for an abnormal rhythm such as atrial fibrillation, or less commonly heart failure, depending on your symptoms, examination and medical history. The timing of an episode is useful but does not establish its cause.

Write down when the sensation began, how long it lasted, what you were doing, what you ate and drank, and whether you had chest discomfort, breathlessness, dizziness or faintness. If possible, note your pulse and whether it felt regular or irregular, without delaying care to measure it.

Stay hydrated, limit stimulants that clearly trigger symptoms, and arrange a medical review for repeated episodes. Do not rely on a gluten-free diet as a heart treatment or start supplements such as iron without advice. A clinician may decide whether an examination, blood tests or heart-rhythm monitoring is appropriate.

Call emergency services if palpitations occur with chest pain, severe breathlessness, fainting, new confusion, marked weakness or a sustained very rapid or irregular heartbeat. Seek prompt medical advice for episodes that are new, increasingly frequent, happen during exertion or occur with swelling or breathlessness when lying down.

Ask whether your symptoms suggest a rhythm problem, anaemia, thyroid disorder, dehydration or blood-sugar issue. Discuss medicines and supplements, caffeine and family heart history, and ask whether you should keep exercising normally while the episodes are being assessed.
