Overview
The framing of the question is worth adjusting first. Nobody "needs" hormone therapy the way someone needs antibiotics for pneumonia. It is a treatment for symptoms, and in some situations for bone and long-term risk — which makes it a decision about trade-offs rather than a diagnosis with a required response.
There are three situations where it clearly earns consideration, and one where it is genuinely recommended rather than merely reasonable.
| Situation | How strongly it applies |
|---|---|
| Vasomotor symptoms affecting daily life | The clearest case. Most effective available treatment |
| Genitourinary symptoms | Clear — though local treatment, not systemic, is usually the answer |
| Menopause before 45 | Generally recommended, at least to the usual age of menopause |
| Bone loss with other risk factors | Reasonable, as part of a wider assessment |
| Fatigue, weight, mood, fog alone | Weakest case. Rule out the mimics first — several are more likely |
| "Optimizing" hormones without symptoms | Not a medical indication. We do not treat on this basis |
The most useful filter: are your symptoms actually interfering with how you live? Not whether a level is low — there is no threshold on a blood test that indicates a need for treatment in a woman over 45. Guidance is explicit that the diagnosis is clinical.
The strongest case
Vasomotor symptoms — hot flashes and night sweats — that are frequent enough or severe enough to interfere with sleep, work or how you feel day to day. Hormone therapy is the most effective treatment available for them, and for women in the favorable window without contraindications, the balance is generally favorable.
That last part matters. "Effective" and "appropriate for you" are different assessments, and the second requires knowing your history. Timing changes the calculation.
Genitourinary symptoms — dryness, discomfort with sex, urinary urgency, recurrent UTIs — are also a clear case, with a caveat: the answer is usually local vaginal estrogen rather than systemic treatment. If that is your only symptom cluster, you may not need systemic hormone therapy at all. What local treatment does.
Menopause before 45 is the situation where it is genuinely recommended rather than optional, because early estrogen loss carries long-term consequences for bone and cardiovascular health over the additional decades involved.
The weakest case, and why
Fatigue, weight change, low mood and brain fog are common in this age range, they are frequently attributed to hormones, and they are the symptoms least likely to respond to hormone therapy alone.
Not because they are not real, and not because hormones are uninvolved. Because the same symptoms are produced by several other conditions that are more common, easier to treat, and worth excluding first:
- Thyroid disease, which peaks in exactly this decade
- Iron depletion, especially where bleeding has become heavier
- B12 and vitamin D deficiency
- Sleep apnea, which rises sharply after menopause and is heavily under-diagnosed in women
- Depression and anxiety
- Alcohol
- Medication
If fatigue is the main symptom and none of the above has been checked, starting hormone therapy is a reasonable-sounding move that frequently produces a disappointed patient three months later — and leaves the actual cause untreated in the meantime. Why tiredness after 50 is not just age.
Where fatigue sits alongside clear vasomotor symptoms, the picture is different — treating the sweats often improves the fatigue by restoring the sleep.
What a blood test can and cannot tell you
This is where a lot of marketing goes wrong, and it is worth being direct about it.
For a woman over 45 with typical symptoms and changing cycles, the diagnosis is clinical. There is no hormone level that indicates a need for treatment, and there is no target level to treat toward. FSH in particular fluctuates enough during the transition that a normal result does not exclude anything. Why testing is more limited than it sounds.
What testing genuinely does here is exclude the mimics — thyroid, iron, B12, vitamin D — and establish a baseline for the things that change through this window, particularly lipids, glucose and blood pressure.
Under 45, testing has a real diagnostic role, because confirming early menopause changes management substantially.
What is assessed before starting
A proper assessment covers, at minimum:
Cardiovascular risk — blood pressure, lipids, smoking, weight, family history. Blood pressure in particular is the most under-measured risk factor in midlife women.
Clot risk — previous venous clot, known thrombophilia, migraine with aura, weight. Several of these point toward transdermal rather than away from treatment entirely.
Breast history — personal and family. A personal history makes this a specialist conversation rather than a general one.
Whether you have a uterus, which determines whether a progestogen is required. And which one matters.
Bleeding pattern, because any abnormal bleeding is investigated before starting rather than after.
What we will not do
We will not start systemic hormone therapy on the basis of a hormone level in a woman without symptoms. There is no evidence supporting it and it is not what the treatment is for.
We will not treat fatigue as a hormonal problem before the common non-hormonal causes have been excluded.
And we will not present hormone therapy as a longevity intervention. It has real benefits for symptoms and for bone. Extending those into a general healthspan claim goes beyond what the evidence supports, whatever the surrounding market does.
Frequently asked questions
How do I know if I need HRT? The practical test is whether your symptoms are interfering with how you live, and whether the alternatives have been considered. There is no blood test that establishes a need for it over 45.
Can a blood test tell me? Not over 45 — the diagnosis is clinical. Testing is useful for excluding thyroid disease, anemia and other explanations, and for a baseline. Under 45 it has a real diagnostic role.
What if my only symptom is fatigue? Then the non-hormonal causes should be checked first. Fatigue alone is the symptom least likely to respond to hormone therapy and most likely to have another explanation.
Do I need it for my bones? It is effective for bone loss and may be part of the picture, particularly with other risk factors — but bone protection alone is a fuller assessment rather than an automatic indication.
What if I just want to feel better? Reasonable, and worth a conversation — one that starts with what specifically is not right and what else could account for it, rather than with a prescription.
Where this fits in your plan
The productive first step is usually not a hormone panel. It is a clear description of what has changed, plus a panel that rules out the conditions that mimic it.
From there the hormone conversation is a real one — with your symptoms, your risk profile and your preferences in it — rather than a decision made from a number. What we check, and what hormone therapy with us involves.
We measure first. Then we act.
Diagnostic testing does not diagnose or rule out disease on its own and is interpreted by a licensed provider alongside your history and examination.

It starts with measuring, not guessing. A short, clinician-reviewed assessment shows what fits you.
