Dr. Sondos Al Sad, a primary care doctor at UCSF in San Francisco, has spent years helping women through menopause. And she kept noticing the same problem: too many of her patients were struggling with hot flashes, sleepless nights, and achy joints — yet avoiding a treatment that could help them.

That treatment is called hormone replacement therapy, or HRT — medicine that replaces estrogen the body stops making after menopause. For decades, millions of women took it to ease symptoms and protect their bones. Then, in 2002, a major study raised alarms about stroke, blood clots, and breast cancer. Use dropped dramatically almost overnight.

Here is the key thing most women never heard: those dangers were mainly found in older women who started HRT long after menopause. But the warnings applied to everyone, causing widespread fear that lasted for over 20 years.

That is finally changing. Federal health officials recently removed the strictest warnings from HRT labels and updated guidance on who should use it. The goal, Dr. Al Sad says, is to calm fears that led to too many women going without help.

More than four out of five women experience symptoms during menopause that can disrupt their lives — from hot flashes and brain fog to vaginal dryness and weakening bones. Menopause is not a single moment but a transition that includes perimenopause, when periods become irregular, and postmenopause, the years after.

The updated guidance says hormone therapy works best and carries fewer risks when started within 10 years of the final menstrual period, or before age 60. How long a woman takes it should be decided together with her doctor — there is no fixed rule. When tailored to each person, HRT can reduce hot flashes, improve sleep, protect bones, and support bladder and vaginal health.

Dr. Al Sad founded The Menopause Connection at UCSF's Women's Health Primary Care Clinic. She says the shift comes from better science, clearer guidelines, and more women doctors leading the conversation. Patients are also more informed and demanding care that improves their quality of life.

"It is a combination of evidence and advocacy," she said.

The changes matter because when women stopped HRT after the early-2000s concerns, many went without treatment. Doctors say this likely contributed to more cases of osteoporosis, a condition that weakens bones. The fear and confusion from that era are still affecting care today.

But the tide is turning. With stronger research and updated advice, women now have better tools to manage a life stage that half the population will experience. Dr. Al Sad and others hope the conversation — finally — is becoming one worth having.
