What it is
Estrogen falls as your ovaries wind down. That drop drives hot flashes, night sweats, and broken sleep. Estrogen therapy, often called HRT, replaces some of what your ovaries stopped making.
It comes as a patch, gel, spray, or pill. Dr. Mueller usually starts with a patch. It gives steady dosing and bypasses the liver, which is linked to a lower risk of blood clots. The estradiol in these products is the same molecule your ovaries made.
Estrogen is the most effective treatment for hot flashes. It also prevents the rapid bone loss that follows menopause. If you still have a uterus, you take progesterone with it.

Questions people ask
- Is HRT safe?
- For healthy women under 60, or within 10 years of their final period, benefits generally outweigh risks for bothersome hot flashes. Dr. Mueller goes through your history first.
- Will HRT make me gain weight?
- Studies do not show hormone therapy causes weight gain. Menopause itself shifts weight toward the middle, treated or not.
- How long can I stay on it?
- There is no fixed stop date. You and Dr. Mueller review the dose and the reasons for it each year.
- Patch or pill: which is better?
- Patches and gels skip the liver. Studies link them to a lower clot risk than pills. Dr. Mueller usually starts there.
- Do I need progesterone too?
- Yes, if you have a uterus. Estrogen alone can thicken the uterine lining. Progesterone protects it.
- Is this bioidentical?
- FDA-approved estradiol is the same molecule your ovaries made. You do not need a compounding pharmacy to get it.
