Hormone Therapy for Menopause and Perimenopause

By Francesca ColtreraYour need-to-know guide to today's hormone therapy -- what's safe, what's new, what's right for you Not long ago, a friend told me about a coffee date she’d had with a 50-something former office mate, Susan.

Hot flashes are one of the most common signs of perimenopause, the years leading up to menopause. Menopause, when your period stops for good, typically happens between age 45 and 55.

Some women experience the heat and flushing of hot flashes without sweating, while others sweat so much they need a change of clothes. When hot flashes happen at night, leaving you and your sheets drenched, they’re called night sweats.

For about 75% of women, hot flashes and night sweats are a fact of life during perimenopause and menopause. A lucky minority won’t experience them at all. Some women will experience only mild hot flashes.

But for 25% - 30% of women, hot flashes and night sweats will be severe enough to interfere with quality of life, says Valerie Omicioli, MD, clinical assistant professor of obstetrics, gynecology, and reproductive science and a certified menopause practitioner at the University of Maryland School of Medicine in Baltimore.

A single hot flash can last anywhere from one to five minutes and may occur a few times a week for some women or daily for others. When hot flashes are severe, they may strike four or five times an hour or 20 to 30 times a day, Omicioli says.
