The short answer: hormone therapy is most effective for hot flushes, night sweats, vaginal and urinary symptoms, and protecting bone. Current guidelines favour it for women under 60, or within ten years of menopause, and in November 2025 the FDA removed several long-standing warnings from the labels. For the right person it can be one of the more meaningful things we do.
Most hormone conversations in our office start the same way. "I don't feel like myself." Sleep is lighter. Energy is patchy. Mood is shorter-fused than it used to be. None of that is in your head, and it often shows up before anyone says the word menopause out loud.
What changed on the FDA label?
A great deal, and recently enough that a lot of what you will read online predates it.
In November 2025 the FDA moved to remove the boxed warnings for cardiovascular disease, breast cancer and probable dementia from menopausal hormone therapy products (FDA). In February 2026 it approved those labeling changes across six products in four categories (FDA).
The FDA also asked to remove the old instruction to use the lowest effective dose for the shortest possible time. That single sentence shaped twenty years of prescribing advice, and its removal means treatment can be tailored to you and continued as long as it is serving you, rather than tapered on a clock.
One detail worth knowing: systemic estrogen-alone products keep a boxed warning relating to endometrial cancer, which is why a woman with a uterus is prescribed a progestogen alongside estrogen. That combination is standard practice and it is the reason the warning exists.
Who is a good candidate?
The guidelines are unusually consistent. For women under 60, or within ten years of menopause onset, without contraindications, the benefit-to-risk balance favours treatment of bothersome symptoms and prevention of bone loss (The Menopause Society 2022 position statement). The European Society of Endocrinology's 2025 guideline lands in the same window (Lumsden et al., European Journal of Endocrinology).
That window shows up in the long-term data too. In eighteen years of follow-up from the Women's Health Initiative, women who began hormone therapy between the ages of 50 and 59 had lower all-cause mortality, with a hazard ratio of 0.69 (Manson et al., JAMA).
Starting earlier in the transition, rather than waiting until symptoms have gone on for years, is one of the more useful things to know about this treatment.
What does it help most with?
Hot flushes and night sweats respond substantially. A Cochrane review of 21 trials and 2,511 women found a large reduction in weekly hot flush frequency compared with placebo.
Vaginal and urinary symptoms respond well, particularly to low-dose local estrogen, which The Menopause Society describes as a safe and effective therapy.
Bone protection is real and measurable. In the Women's Health Initiative, total fractures occurred in 8.6% of women on therapy compared with 11.1% on placebo (Cauley et al., JAMA).
Those three are where the evidence is strongest, and they are what we prescribe for.
Why the route matters
This is one of the most practical things we can tell you, and it shapes a lot of our prescribing.
In a study of 80,396 women matched to 391,494 controls, transdermal estrogen, meaning a patch or gel, was not associated with an increased risk of venous thromboembolism, while oral routes were (Vinogradova et al., BMJ).
Delivered through the skin, estrogen goes straight into the bloodstream rather than passing through the liver first. That is why a patch is frequently where we start, and why asking about route is a good question to bring to any prescriber.
Common signs we hear about
- Energy. A baseline tiredness that does not respond to sleep.
- Sleep. Falling asleep is fine; staying asleep is not.
- Mood. A shorter fuse than the one you used to have.
- Libido. Reduced interest, and reduced everything around interest.
- Skin. Drier, thinner, slower to bounce back.
- Brain. The word you wanted is on the tip of your tongue all day.
One or two of these on their own is often a lifestyle conversation. A cluster of them, especially in your late thirties through fifties, is usually a hormone conversation.
Do you need a blood test first?
For diagnosis, usually not. Menopause is confirmed clinically, after twelve months without a period, and in perimenopause hormone levels swing widely enough that a single reading tells you little. The European Society of Endocrinology's 2025 guideline states that biochemical testing is not necessary for diagnosing perimenopause in women over 45.
We do run labs, and it is worth explaining why, because the reason is not diagnosis. We check thyroid, iron, vitamin D and metabolic markers to identify anything else contributing to how you feel, and to establish a baseline before starting treatment. That is useful information, and it often changes the plan.
What we prescribe
We use FDA-approved formulations, in doses matched to your symptoms and adjusted over time.
That includes body-identical estradiol and micronized progesterone, which are structurally identical to the hormones your body makes and are available as approved products. You do not need a compounding pharmacy to get them, and approved products come with consistent dosing and established safety data.
On delivery, we discuss patches, gels, and local vaginal preparations alongside oral options, and we choose with you.
What we'll talk about at your consult
- Your full symptom picture and how long it has been going on.
- Personal and family history, including any history of breast cancer, blood clots, stroke or liver disease, each of which shapes candidacy.
- Whether you still have a uterus, which determines whether a progestogen is part of your regimen.
- Any current medications.
- What success would look like for you, and how we will check we got there.
Hormone therapy is prescribed for symptoms and bone protection. Alongside it, sleep, protein, strength training and sunlight do real work, and we will talk about those too.
How does this connect to skin and weight?
Two knock-on effects worth naming, because they are often how people find us.
- Skin. Estrogen is part of how skin retains hydration and produces collagen. A steady skincare routine alongside the hormone conversation is a fuller picture than either alone.
- Weight. When sleep, cortisol, thyroid and sex hormones are all off-step, the scale gets stubborn regardless of how clean the food is. That is the conversation we have in our medical weight loss program, and we run both sides here.
Hormones are not the answer to everything. They are sometimes the missing one.
