Caffeine withdrawal and heart palpitations

Caffeine affects alertness and the nervous system. After regular use, stopping suddenly may bring headache, tiredness, irritability, difficulty concentrating, or a heightened awareness of the heartbeat. Palpitations can feel like fluttering, pounding, skipped beats, or a racing pulse. Withdrawal is one possible explanation, but it should not be used to dismiss a new rhythm change.

Dehydration, anxiety, low blood sugar, thyroid overactivity, anaemia, and heart-rhythm conditions can also cause palpitations. A clinician may ask when the sensation began, how long episodes last, and whether they occur with exertion.

Rest, drink water regularly, and avoid replacing coffee with energy drinks, nicotine, or decongestants. If you stopped abruptly and symptoms are mild, a gradual reduction plan may be easier than repeated large changes; discuss the plan if you are pregnant or have a heart condition. Keep a brief record of timing, pulse feel, triggers, medicines, and other symptoms.

Seek emergency help for palpitations with chest pain, fainting, severe breathlessness, confusion, or marked weakness. Arrange prompt medical review if episodes keep returning, last longer than expected, begin during exercise, or come with dizziness. Assessment may include an examination, an electrocardiogram, and blood tests.

Could another medicine, supplement, thyroid problem, anaemia, dehydration, or rhythm disorder be contributing? Should I reduce caffeine gradually, and do I need an electrocardiogram or blood tests?
