what causes hot flashes

Hello Anon

Thank you for writing.

How old are you? Are you female?

Hot flashes are common symptoms of menopause and perimenopause.

Hot flashes are sudden waves of heat that can start in the waist or chest and work up to the neck and face and sometimes to the rest of the body. They can be accompanied by a rapid heartbeat. The upper body, including the scalp may sweat profusely. Some women also become red. In addition to being an internal sensation, the surface of the skin, especially on the face, becomes hot to the touch. This may be why you have the red patches.

Medication can also cause hot flashes. Generally, hot flashes are due to hormonal fluctuations.

You will need to see your doctor to know more and please have the red patches examined.
Best,
Susan
