Hot flashes when it may not be menopause

A hot flash is a brief feeling of heat, flushing or sweating caused by a change in the body's temperature-control signals. Menopause and perimenopause are common contexts, but they are not the only ones. A fever or infection, thyroid overactivity, low blood sugar, anxiety, alcohol, warm surroundings and some medicines can feel similar. Hormone changes related to pregnancy, the menstrual cycle or premature ovarian insufficiency may also matter.

Look at the full pattern: age, periods, medicines, supplements, sleep, appetite, weight, heart rate and fever. A symptom diary can show whether episodes follow meals, exertion, stress, a cycle phase or a new treatment. That information is more useful than trying to diagnose yourself from warmth alone.

Cool the room, wear breathable layers, drink water and pause safely if an episode causes dizziness. Review recent medicine or supplement changes with a pharmacist rather than stopping prescribed treatment on your own. Record temperature if you feel feverish, plus the episode's timing and associated symptoms. A clinician can decide whether an examination or targeted tests are needed and can discuss non-hormonal treatment when appropriate.

Arrange an appointment for recurring or unexplained episodes, especially with irregular periods, persistent fever, tremor, diarrhoea, unexplained weight change or a racing heartbeat. Seek urgent care for chest pain, severe breathlessness, fainting, confusion, severe weakness or a very high fever. These symptoms need assessment even if the episode passes.

Ask what causes fit your timing and other symptoms, whether a medicine review or thyroid assessment is appropriate, and how to distinguish a hot flash from fever. Bring your diary and a complete list of medicines and supplements.
