Fish oil and heart palpitations

Short answer
Heart palpitations while taking fish oil deserve a medication review because several conditions and triggers can cause them.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

What palpitations can represent
Palpitations may feel like pounding, fluttering, skipped beats, or a racing heartbeat. Fish oil may be one detail in the timeline, but palpitations can also occur with dehydration, low blood sugar, anaemia, an overactive thyroid, anxiety, fever, caffeine, or some medicines. Atrial fibrillation is one possible rhythm cause, while many episodes are not caused by a dangerous rhythm. The description, duration, pulse pattern, and associated symptoms help guide assessment.
What to do now
Record when episodes happen, how long they last, what the heartbeat feels like, and the fish oil product and dose. Note caffeine, exercise, illness, stress, and other medicines. Drink normally unless a clinician has restricted fluids. Arrange a medication and health review before changing supplements, especially if fish oil was recommended for a specific reason. A clinician may check your pulse, blood tests, or heart rhythm.
When urgent assessment matters
Call emergency services if palpitations occur with chest pain, severe shortness of breath, fainting, new confusion, or weakness or numbness on one side. Seek prompt care for a first episode that does not settle, repeated episodes with dizziness, or palpitations alongside swelling or breathlessness that could suggest Heart Failure. Do not drive yourself if you feel faint.
Questions to bring
Ask whether you need an ECG, blood tests for anaemia or thyroid problems, or a monitor for intermittent episodes. Discuss whether to continue fish oil, possible interactions, and which pulse or symptom changes should prompt urgent care.

Questions people ask
Should fish oil be blamed for every palpitation?
No. The timing may be relevant, but dehydration, anaemia, thyroid disease, anxiety, medicines, and rhythm conditions can also contribute.
What test checks an irregular heartbeat?
An ECG records the heart rhythm; longer monitoring may be considered when episodes are intermittent.
