Why Do I Have Hot Flashes And Nausea When I’m Not In Menopause?

I’m 27. I was haivng these symptoms a for a while, but they stopped for a few months until today. I get a wierd tingling sensation all over then i feel super hot and then very nauses. Sometimes i dry heave, sometimes i vomit, and sometimes i can keep it in (like in a meeting at work). I’m to young for menopause, what’s going on with my body?

My Sister Is Going Through Menopause And Is 40 Years Old. Do The Usual Symptoms Include Nausea?

She felt faint the other day and has been having a lot of headaches, chills and sweats. Are these menopausal symptoms too?
