Key Takeaways
Cycle spotting on HRT is common, but new spotting between periods isn't
Dr. Green covered that HRT works alongside the ovaries rather than overriding them, so cycles can stay irregular even on treatment. He noted that spotting which replaces a normal period is expected, but spotting between otherwise regular bleeding warrants an exam to rule out other causes.
Dose changes over time reflect the ovaries' declining hormone production, not tolerance
Dr. Green explained that the body doesn't get "used to" HRT, adjustments are needed because the ovaries produce less hormone over time, not because the treatment stops working. He noted this can happen gradually or, occasionally, ovaries can briefly produce more, requiring a dose decrease instead.
Most side effects show up early and fade within the first few weeks
Dr. Green noted that nausea, bloating, and water retention are the most common early side effects, and they typically resolve once the body adjusts to steady hormone levels around the three-week mark. He noted that dangerous side effects like blood clots are extremely rare.
Vaginal estrogen can meaningfully reduce recurrent UTIs tied to low estrogen
Dr. Green detailed how declining estrogen thins vaginal and urethral tissue, making it easier for bacteria to cause infections. He noted that systemic HRT often helps, but vaginal estrogen cream can add extra local benefit for women who need it.
Hormone lab testing doesn't guide HRT dosing decisions
Dr. Green clarified that hormone levels fluctuate throughout the day, making lab tests an unreliable snapshot rather than useful data. He said Winona, like ACOG and the Menopause Society, relies on symptoms rather than lab values to determine whether a dose is working.
