Magnesium for hot flashes: what to know

A hot flash is a sudden feeling of heat that may affect the face, neck or chest and can be followed by sweating or chills. Hormone changes during [Perimenopause](/conditions/perimenopause/) and [Menopause](/conditions/menopause/) can alter temperature regulation. Magnesium does not replace an assessment of the pattern, triggers, medicines and other symptoms. Hot flashes can also occur with some medical conditions or treatments, so the symptom itself does not identify one cause.

Track when episodes occur, how long they last and possible triggers such as warmth, alcohol, spicy food, stress or poor sleep. Choose breathable layers, keep the bedroom cool and drink enough fluid. If you want magnesium, favour food sources and ask a pharmacist about supplements, interactions and kidney health. For frequent or disruptive episodes, discuss [Hormone Replacement Therapy](/treatments/menopause-and-hormone-therapy/hormone-replacement-therapy/) or [Non-Hormonal Menopause Treatment](/treatments/menopause-and-hormone-therapy/non-hormonal-menopause-treatment/) rather than relying on an unproven supplement.

Book an appointment if hot flashes are new, worsening, disturbing sleep or affecting work. Seek urgent help for heat with confusion, collapse, severe breathlessness, chest pain or a very unwell feeling. Medical review is also useful when episodes begin outside the expected menopause transition or occur with unexplained weight change, persistent fever or unusual bleeding.

Could my episodes be related to menopause or another cause? Are any of my medicines contributing? Would hormone or non-hormonal treatment suit my history? Is magnesium appropriate with my medicines and kidney function?
