Does perimenopause cause hot flushes?

As ovarian hormone levels fluctuate, the brain's temperature-control centre can become more sensitive to small changes in body temperature. It may trigger widening of skin blood vessels and sweating, followed by chills as the body cools. Episodes can happen during the day or at night and may disturb sleep.

Hot flushes can occur with other perimenopause changes, such as cycle changes, mood shifts, vaginal dryness, or sleep difficulty. They are not specific to perimenopause, so medicines, thyroid conditions, infection, and other causes may need consideration when symptoms are unusual or new.

Notice possible triggers such as warm rooms, alcohol, spicy food, stress, or tight clothing. Dress in removable layers, keep the bedroom cool, and use breathable bedding. Record timing, triggers, sleep disruption, and medicines. A clinician can discuss non-hormonal options and whether hormone treatment is appropriate for your medical history.

Arrange medical advice if flushing is persistent, severe, newly different, or accompanied by unexplained weight change, fever, chest discomfort, fainting, or a racing heartbeat. Seek urgent care for chest pain, severe breathlessness, confusion, or collapse. Night sweats that soak clothing or bedding also deserve assessment.

Ask whether your pattern fits perimenopause, whether another cause should be checked, and which treatment options match your symptoms and health history. Mention migraines, clotting problems, liver disease, or breast concerns because they can affect treatment choices.
