Hormone Replacement Therapy (HRT) is a clinical treatment designed to replenish the hormones oestrogen and progesterone that naturally decline during perimenopause and menopause. By restoring these hormones to more stable levels, HRT effectively manages the wide range of physical and psychological symptoms caused by hormonal fluctuations. In 2026, clinical guidelines continue to recommend HRT as the first line treatment for most women, as it not only improves quality of life but also provides significant long term protection for bone and heart health.

What exactly is HRT?
HRT works by replacing the oestrogen that the ovaries stop producing as a person reaches the end of their reproductive life. For most women, oestrogen is the primary hormone needed to relieve symptoms. However, if you still have your womb (uterus), taking oestrogen alone can cause the lining of the womb to thicken, which increases the risk of cancer. Therefore, progesterone, or a synthetic version called progestogen, is added to protect the womb lining.
Hormone therapy is categorised into two main approaches based on your surgical history and stage of menopause.
- Oestrogen only HRT: Usually prescribed for women who have had a hysterectomy.
- Combined HRT: Includes both oestrogen and progestogen for women who still have their womb.
- Cyclical (Sequential) HRT: For those in perimenopause who still have periods; it mimics a natural cycle and results in a monthly withdrawal bleed.
- Continuous Combined HRT: For those who have reached menopause (no periods for a year); it is taken daily without a break and is bleed free.
How does HRT help menopause symptoms?
HRT is highly effective because it addresses the root cause of menopause symptoms: hormone deficiency. Once hormone levels are stabilised, many of the body’s systems return to more balanced functioning.
Relief of physical symptoms
The most well known benefit of HRT is the reduction of vasomotor symptoms. Hot flushes and night sweats often improve within a few weeks of starting treatment. Oestrogen helps the brain’s thermostat (the hypothalamus) stay regulated, preventing the sudden spikes in body temperature that lead to discomfort. It also helps with joint and muscle aches by reducing inflammation and keeping tissues hydrated.
Psychological and cognitive support
Declining oestrogen directly impacts neurotransmitters like serotonin and dopamine, which regulate mood. HRT can significantly alleviate the anxiety, irritability, and low mood that many experience during perimenopause. Many women also report an improvement in brain fog and concentration, as hormones play a vital role in cognitive processing and memory.
Sleep and energy
By stopping night sweats, HRT allows for deeper, more restorative sleep. Improved sleep quality naturally leads to better energy levels and a more stable mood during the day, creating a positive cycle of well being.
Long term health benefits
Beyond immediate symptom relief, HRT is prescribed for its protective effects on the body as it ages.
Engaging with HRT early in the menopause transition provides a window of opportunity for significant health protection. Oestrogen is essential for maintaining bone mineral density; HRT is the gold standard for preventing and treating osteoporosis, reducing the risk of fractures in later life. Additionally, starting HRT before age 60 or within 10 years of menopause has been shown to have a protective effect on the cardiovascular system, potentially lowering the risk of heart disease and stroke in healthy women.
- Bone Health: Prevents the rapid bone loss that occurs in the first five years of menopause.
- Heart Health: Helps maintain healthy cholesterol levels and supports the elasticity of blood vessels.
- Diabetes Risk: Some studies suggest HRT can improve insulin sensitivity and lower the risk of Type 2 diabetes.
Understanding body identical HRT
In 2026, many clinicians prefer to prescribe body identical HRT. This type of hormone therapy is derived from natural plant sources (such as yams) and has the exact same molecular structure as the hormones produced by the human body. This is distinct from compounded bioidentical hormones, which are unregulated and not recommended by major medical societies.
Regulated body identical HRT, such as micronised progesterone and 17\beta-oestradiol, is considered the safest option. When delivered through the skin via patches, gels, or sprays, oestrogen does not increase the risk of blood clots, making it a suitable choice for a wider range of women, including those with higher blood pressure or BMI.
To Summarise
HRT is a safe and highly effective medical treatment that replaces the hormones your body no longer makes. It provides rapid relief from disruptive symptoms like hot flushes and mood swings while offering essential long term protection for your heart and bones. Whether you choose a patch, gel, or tablet, the goal of HRT is to restore your quality of life and support your health throughout the menopause transition. Consistency and individualised care are key to finding the right balance for your body.
If you experience sudden, severe chest pain, shortness of breath, or a sudden loss of coordination while on HRT, call 999 immediately.
Will HRT make me put on weight?
There is no clinical evidence that HRT causes weight gain. Weight changes in midlife are more often related to age and metabolic shifts, and HRT can actually help some women manage their weight by improving energy levels for exercise.
Is HRT safe?
For the vast majority of women under age 60, the benefits of HRT far outweigh the risks. While there is a small increased risk of breast cancer with combined HRT after long term use, this risk is similar to or lower than other lifestyle factors like being overweight or drinking alcohol.
How long should I take HRT?
There is no fixed limit on how long you can take HRT. Many women continue for several years or even decades, depending on their symptoms and health goals. Yearly reviews with your doctor help ensure it remains the right choice for you.
Does HRT prevent dementia?
While some research suggests a protective effect if started early, clinical guidelines currently do not recommend HRT specifically for the prevention of dementia. However, it is proven to help with the brain fog associated with menopause.
What are the side effects of HRT?
Common side effects include breast tenderness, bloating, and occasional headaches. These usually settle within the first three months as your body adjusts to the new hormone levels.
Can I take HRT if I have had a blood clot?
Yes, but you would likely be prescribed oestrogen through the skin trans dermally rather than in tablet form, as patches and gels do not increase the risk of clots.
