Hi, yuck. Sorry you are having hot flashes!! I get them but am in the throes of the whole going through menopause thing so mine are hormonal in nature. But I DO feel your pain! There are definitely reasons for hot flashes other than just menopause. And I'd talk to your doctor about this. So, some questions. Are you taking any new medications? How is your weight? Need to lose a few pounds? Being overweight can mess with metabolism which can then cause the flashes. Certain foods can trigger it and alcohol especially. This can develop over time. Big one . . . anxiety. How's your stress and anxiety level? Another really big one is thyroid issues. Have you had your thyroid checked any time recently? We'll start the discussion there. Let me know.
I relate hormones to hot flashes, that is, the change of hormone levels. And fat cells both produce hormones in small amounts, and release them when the person loses a little weight. When you talk to your doctor, be sure to discuss that relationship, especially if you are dieting and managing to lose a little weight. Good luck!
