New guidelines back use of hormone therapy for menopause, perimenopause symptoms. Here's what to know.

The American College of Obstetricians and Gynecologists has released new guidance for the treatment of common menopause and perimenopause symptoms, including recommending hormone replacement therapy for many women with hot flashes and night sweats. It's the first time in more than a decade that the group, which is the leading OB-GYN professional organization in the United States, is changing its advice on the use of hormone therapy for menopause and perimenopause."Hormone replacement therapy is now the first line" for vasomotor symptoms including hot flashes, night sweats and sleep issues, said Dr. Kameelah Phillips, an OB-GYN and menopause specialist. "Before, we used to say, 'Here's an antidepressant. Make sure you work out. Why don't you try a glass of wine?' All of those were not helpful," Phillips said in an interview on "CBS Mornings." "We're using hormones mainstream now."
