Common Symptoms
| Symptom | Prevalence | Impact |
|---|---|---|
| Hot flushes / night sweats | 70–80% | Most bothersome; disrupt sleep |
| Vaginal dryness / GSM | 50% | Dyspareunia, UTIs, urgency |
| Mood changes / low mood | 40–50% | Not depression per se; oestrogen-related |
| Cognitive symptoms ('brain fog') | 60% | Poor concentration, word-finding |
| Sleep disturbance | 60% | Often from night sweats; independent effect |
| Musculoskeletal aches | 60% | Joint pains; often overlooked |
| Loss of libido | 40% | Multiple drivers: testosterone, psychological, GSM |
HRT: Benefits and Risks
| Benefit | Evidence |
|---|---|
| Hot flush relief | HRT most effective treatment: 80% reduction |
| Bone protection | Reduces fracture risk during use (40–50%) |
| Cardiovascular protection | When started within 10 years of menopause or before 60: reduces CVD risk |
| Mood and cognition | Significant improvement in many women |
| GSM treatment | Topical oestrogen highly effective; no systemic risk |
Transdermal HRT Is SaferOral oestrogen increases blood clot risk (VTE). Transdermal patches, gels, or sprays bypass liver first-pass metabolism and do not increase VTE risk: preferred for women with VTE risk factors or history.
Premature Menopause Needs HRTWomen under 45 who experience menopause should take HRT until at least age 51: to protect bones, heart, and brain from premature oestrogen deficiency. This is not elective, it's protective.
Does HRT increase breast cancer risk?
Combined HRT (oestrogen + progestogen) does modestly increase breast cancer risk, roughly equivalent to drinking 1–2 units of alcohol per night, or being overweight. The risk disappears after stopping HRT. Body-identical progesterone (micronised) may carry lower risk than synthetic progestogens.
How long can I take HRT?
There's no defined maximum duration. NICE recommends discussing benefits and risks annually. Many women continue beyond 5–10 years, especially for bone protection or ongoing symptoms. A 2019 large UK study reassessed and found the absolute risk is small.
Can HRT be started after 60?
Yes, but with more caution. Starting after 60 or >10 years after menopause may carry higher cardiovascular risk. The 'critical window' hypothesis suggests early initiation is most protective. Discuss risk-benefit with your GP or menopause specialist.
What is the Mirena coil's role in HRT?
The Mirena (levonorgestrel) coil provides the progestogen component of combined HRT when used alongside oestrogen patches/gel: protecting the uterine lining without systemic progestogen effects.
