The Benefits and Risks of Hormone Replacement Therapy (HRT)
Hormone Replacement Therapy (HRT) is a widely used medical treatment, especially among women going through menopause. By replenishing oestrogen and progesterone levels in the body, HRT helps to ease the uncomfortable symptoms of menopause, including hot flushes, mood swings, night sweats, and vaginal dryness. However, as with any medical intervention, HRT comes with its own set of risks and side effects.
This comprehensive guide explores the potential benefits and risks of HRT, who should consider it, and what alternatives are available.
What Is Hormone Replacement Therapy?
HRT involves supplementing the body with hormones—primarily oestrogen and sometimes progesterone or progestin—to replace those the body no longer produces naturally during menopause.
There are two main types of HRT:
- Combined HRT: Contains both oestrogen and progesterone, typically prescribed to women who still have their uterus.
- Oestrogen-only HRT: Prescribed for women who have had a hysterectomy.
Benefits of Hormone Replacement Therapy
1. Relief from Menopausal Symptoms
HRT is highly effective in alleviating common menopausal symptoms such as:
- Hot flushes and night sweats
- Vaginal dryness and discomfort during sex
- Mood swings and irritability
- Sleep disturbances
2. Bone Health Support
Oestrogen plays a key role in maintaining bone density. Post-menopausal women are at increased risk for osteoporosis. HRT helps reduce this risk and prevent fractures.
3. Improved Skin and Hair Quality
Some women report improved skin elasticity and hair texture while on HRT, as oestrogen helps maintain collagen production.
4. Urinary Health
HRT can help alleviate urinary symptoms, including frequent urination or urgency, and reduce the risk of urinary tract infections (UTIs).
Risks and Side Effects of HRT
Despite its benefits, HRT is not suitable for everyone. Some women may experience side effects or face increased health risks.
1. Increased Risk of Breast Cancer
Several studies indicate a slight increase in the risk of breast cancer with long-term use of combined HRT. Risk reduces once HRT is discontinued.
2. Blood Clots and Stroke
Oral HRT has been associated with an increased risk of blood clots and stroke. This risk is generally lower with transdermal patches or gels.
3. Heart Disease
Earlier studies suggested HRT increased the risk of heart disease. However, newer evidence shows that starting HRT before age 60 or within 10 years of menopause may be safer.
4. Other Side Effects
- Bloating
- Breast tenderness
- Headaches
- Nausea
Who Should Avoid HRT?
HRT is not recommended for women who:
- Have a history of breast or ovarian cancer
- Have experienced blood clots or stroke
- Have untreated high blood pressure
- Have liver disease
Always consult your healthcare provider before starting HRT to ensure it aligns with your health profile.
Types of HRT Available
- Tablets: Easy to take but may carry a higher risk of blood clots.
- Patches: Lower clotting risk; applied to the skin twice a week.
- Gels: Rubbed into the skin daily; ideal for steady hormone levels.
- Implants: Small pellets inserted under the skin that release hormones gradually.
- Vaginal creams and rings: Localised treatment for vaginal dryness.
Alternatives to HRT
For those unable or unwilling to take HRT, the following options may provide relief:
- Phytoestrogens: Plant-based oestrogens found in soy, flaxseed, and legumes.
- Antidepressants: Certain SSRIs may reduce hot flushes and mood swings.
- CBT (Cognitive Behavioural Therapy): Helps manage anxiety, depression, and insomnia linked to menopause.
- Diet and Exercise: A healthy lifestyle can reduce symptoms and improve overall wellbeing.
FAQs About Hormone Replacement Therapy
Q1: How long can I stay on HRT?
There is no strict limit, but the lowest effective dose should be used for the shortest duration needed. Some women stay on HRT for years under medical supervision.
Q2: Can HRT help with weight loss?
HRT is not a weight-loss treatment. However, it may reduce fat redistribution and help you feel more energetic to stay active.
Q3: Are there natural ways to balance hormones?
Yes, diet, exercise, stress management, and herbal remedies may help, but they are usually less potent than medical HRT.
Q4: Is HRT safe after 60?
Risks increase with age. It is usually not recommended to start HRT for the first time after age 60. However, continuation under medical advice is sometimes possible.
Q5: Does HRT delay ageing?
While it won’t stop ageing, it may help with symptoms like bone loss, skin dryness, and mood stability—contributing to better quality of life.
