HRT Guide: Hormone Replacement Therapy for Menopause

Hormone replacement therapy (HRT) — also called menopausal hormone therapy (MHT) — is the most effective treatment available for menopause and perimenopause symptoms. Yet many women are confused about it, worried about risks, or simply unaware of how much it can help.

This guide covers everything: what HRT is, how it works, the different types, the real evidence on risks and benefits, and how tracking your symptoms can help you and your doctor optimize your dose.

What Is HRT?

HRT replaces the hormones — primarily estrogen, and often progesterone — that your ovaries stop producing as you go through menopause. These hormones regulate dozens of body systems, which is why their decline causes such wide-ranging symptoms.

HRT does not prevent menopause. It treats the symptoms caused by falling hormone levels and provides additional health benefits, particularly for bone density and cardiovascular health when started early in menopause.

Who Can Benefit From HRT?

HRT is appropriate for most healthy women under 60 who are:

In perimenopause or within 10 years of menopause
Experiencing moderate to severe menopause symptoms
At risk for osteoporosis
Experiencing premature ovarian insufficiency (POI)

Talk to your doctor if you have a history of breast cancer, blood clots, stroke, or liver disease — these conditions require careful evaluation before starting HRT.

Types of HRT

Estrogen-Only HRT

Prescribed if you have had a hysterectomy (no uterus). Estrogen alone is highly effective for symptoms and carries no increased risk of uterine cancer because there is no uterus.

Forms: pills, patches, gels, sprays, vaginal rings

Combined HRT (Estrogen + Progesterone)

If you have a uterus, you need progesterone alongside estrogen to protect the uterine lining. Without it, estrogen-only HRT increases the risk of uterine cancer.

Forms: combined pills, patches, or separate estrogen + progesterone

Local (Vaginal) Estrogen

Low-dose estrogen applied directly to vaginal tissue. Treats vaginal dryness, urinary symptoms, and painful sex without significant systemic absorption. Can be used by women who cannot take systemic HRT.

Forms: vaginal creams, pessaries, rings, tablets

Bioidentical HRT

Hormones with the same molecular structure as those your body makes. All regulated bioidentical HRT (available on prescription) is safe and evidence-based. Compounded bioidentical preparations are not regulated and should be avoided.

Routes of Administration

| Route | Examples | Notes | |-------|----------|-------| | Oral pills | Estradiol, Utrogestan | Convenient but first-pass liver metabolism | | Transdermal patch | Evorel, Estradot | Lower clot risk than oral; apply to clean, dry skin | | Gel | Oestrogel, Sandrena | Easy dose adjustment; rub into arm or thigh | | Spray | Lenzetto | Quick-drying; applied to forearm | | Vaginal | Vagifem, Estring | Local treatment; minimal systemic absorption | | Implant | Estradiol pellet | Inserted under skin; lasts 4-8 months |

Key point: Transdermal estrogen (patch, gel, spray) does not increase the risk of blood clots, unlike oral estrogen. This makes it the preferred choice for most women.

Benefits of HRT

Symptom relief:

Hot flashes and night sweats reduced by 75-90%
Improved sleep quality
Better mood and reduction in anxiety
Reduced vaginal dryness and painful sex
Improved concentration and reduced brain fog
More consistent energy levels

Long-term health benefits:

30-40% reduction in fracture risk (bone protection)
Reduced cardiovascular disease risk when started within 10 years of menopause
Lower risk of type 2 diabetes
Possible reduction in dementia risk

Understanding the Real Risks

Breast Cancer

The relationship between HRT and breast cancer depends on the type:

Estrogen-only HRT: does not increase breast cancer risk, and may slightly reduce it
Combined HRT (estrogen + progestogen): small increased risk with long-term use (over 5 years) with synthetic progestogens

The absolute risk is small. The increased risk from combined HRT is similar to the risk from drinking 1-2 units of alcohol daily or being overweight.

Micronised progesterone (Utrogestan) appears to carry lower breast cancer risk than synthetic progestogens. Ask your doctor about this option.

Blood Clots (VTE)

Oral estrogen: small increased risk of blood clots
Transdermal estrogen (patch, gel, spray): no increased risk

This is why many guidelines recommend transdermal estrogen as the first choice, especially for women with risk factors.

Stroke

Very small increased risk with oral HRT. Transdermal estrogen does not increase stroke risk.

How to Track Your HRT Response

HRT is not one-size-fits-all. Finding your optimal dose takes time and requires careful monitoring. This is exactly where tracking your symptoms matters.

What to track when starting HRT:

Hot flash frequency and severity (daily)
Sleep quality and night sweats
Mood, anxiety, and brain fog
Energy levels
Vaginal symptoms
Any side effects (breast tenderness, bloating, spotting)

Why tracking helps:

Most women need 2-3 months to feel the full effect of a new HRT dose. Without a symptom log, it is hard to tell whether things are improving, getting worse, or staying the same. Your memory of "how bad things were" is unreliable over weeks.

Tracking also helps your doctor make decisions. "I feel about the same" is much less useful than "my hot flash frequency dropped from 12/day to 4/day but night sweats are unchanged."

MenoCue lets you log symptoms in under 30 seconds and generates visual charts showing your patterns over time — making HRT review appointments dramatically more productive.

Starting HRT: What to Expect

Week 1-2: You may notice some initial side effects as your body adjusts — breast tenderness, slight bloating, mood fluctuations. These usually settle.

Weeks 2-6: Vaginal symptoms and urinary issues often improve first. You may start noticing better sleep.

Months 2-3: Hot flashes and night sweats typically improve significantly. Mood and cognitive symptoms often resolve.

After 3 months: Your doctor will review your response and adjust the dose if needed. If symptoms are not adequately controlled, the dose may be increased.

Questions to Ask Your Doctor

Which type and route of HRT would you recommend for me, and why?
Should I use transdermal rather than oral estrogen for lower clot risk?
Is micronised progesterone an option for me?
How long should I expect to stay on HRT?
What symptoms should I track to evaluate whether my dose is right?
When will we review and potentially adjust my dose?

When to Contact Your Doctor

Contact your doctor promptly if you experience:

Unexpected vaginal bleeding (especially after 12 months without periods)
New breast lumps or changes
Symptoms of blood clot: leg pain, swelling, or breathlessness
Severe headaches or visual changes
Jaundice (yellowing of skin or eyes)

The Bottom Line

HRT is safe, effective, and significantly underused. For most healthy women under 60, the benefits outweigh the risks — particularly when using transdermal estrogen and micronised progesterone.

The key to getting the most from HRT is finding the right type and dose for you. Tracking your symptoms gives you and your doctor the data needed to do that.
