My mom keeps getting hot flashes from almost 12 yrs and she is 58 yrs old now. what woud be the right treatment?

She has options: She may try over-the-counter soy supplements with a reasonable success rate of 30-50%. At 58, depending on medical and family history, she may be able to take a very low dose of estrogen (and Progesterone if she has a uterus) for a few years with a minimal increase in the risk of breast cancer, heart attack and stroke.

Hot flashes: She should see a doctor first to rule out other conditions that mimic menopause. If nothing else is found she cand try hormone replacement therapy if there are no contraindications.
