Perimenopause hot flashes: what to know

During perimenopause, ovarian hormone levels fluctuate rather than changing in a smooth pattern. These shifts can make the body’s temperature-control system react to a small change as if you are overheating. Your face, neck or chest may feel warm, and sweating, flushing or a faster heartbeat may follow. Episodes can occur during the day or at night; night sweats may interrupt sleep. Hot flashes are a common presentation of perimenopause, but heat episodes can also have other causes, including medicines or thyroid problems.

Keep clothing light and easy to remove, use a fan, and keep your bedroom comfortably cool. Notice personal triggers such as warm drinks, spicy food, alcohol, stress or a heated room; a brief symptom diary can reveal patterns. Slow breathing may help an episode pass more comfortably. If symptoms disturb sleep, work or daily plans, a clinician can discuss options, including non-hormonal medicines or hormone treatment, based on your health history. Review other symptoms such as irregular periods, missed periods or mood changes during the appointment.

Arrange medical advice if new sweating or flushing is persistent, severe, worsening, or accompanied by unexplained weight change, fever, chest discomfort, fainting or a racing heartbeat. Seek urgent care for chest pain, severe breathlessness, confusion or fainting. Bleeding that is unusually heavy or occurs after sex also deserves assessment rather than being assumed to be part of perimenopause.

Ask whether your pattern fits perimenopause, whether another condition or medicine could be contributing, and which treatment options suit your medical history. Bring a record of timing, triggers, night sweats, periods and sleep disruption.
