Is HRT Safe? What Women in Dubai Need to Know About the Evidence

Most weeks in my Dubai Marina clinic, a woman in her forties sits down and asks some version of the same question: my mother was told hormones were dangerous — is HRT safe for me? The honest answer is that the question is incomplete, because safety is not a property of HRT. It is a property of the match between HRT and the woman taking it.

What Is Hormone Replacement Therapy?

Hormone replacement therapy — HRT, also called menopausal hormone therapy or MHT — replaces hormones that decline during perimenopause and menopause, primarily estrogen and progesterone.

Estrogen levels fall as ovarian function decreases. Because estrogen receptors are present throughout the body — in bone, blood vessels, skin, brain, bladder and vaginal tissue — this decline can produce effects well beyond the reproductive system. HRT aims to restore hormone levels sufficiently to reduce symptoms and, in some cases, to address longer-term effects such as bone density loss.

HRT is prescribed in two broad forms:

Systemic HRT — estrogen absorbed into the bloodstream, delivered as a patch, gel, spray, tablet or implant, treating symptoms throughout the body. Women with a uterus also take a progestogen.

Local vaginal estrogen — low-dose estrogen applied directly as a cream, pessary, tablet or ring, treating vaginal and urinary symptoms specifically.

Is HRT Safe? What the Research Shows

There is no single answer that applies to every woman. Research consistently shows that the risk-benefit balance of HRT depends on several identifiable factors.

Age and timing

The age at which HRT is started, and the time elapsed since the final menstrual period, are among the strongest influences on outcomes. Studies indicate a more favourable risk-benefit profile for women who begin HRT before age 60 or within ten years of menopause, compared with women starting later. This relationship is often described as the timing hypothesis.

Type of hormone

Different estrogens and progestogens produce different effects. Research distinguishes between conjugated equine estrogen and estradiol, and between synthetic progestins and micronized progesterone. Findings from studies using one combination do not automatically apply to another.

Route of delivery

Oral estrogen passes through the liver before entering general circulation, which affects the production of clotting factors. Estrogen absorbed through the skin — via patch, gel or spray — largely bypasses this first-pass metabolism. Research indicates that this difference is relevant to venous thromboembolism risk.

These three variables mean that "is HRT safe" is answered differently depending on a woman's age, medical history, and the specific regimen used.

Benefits of HRT

Menopause and perimenopause symptom relief

Systemic HRT is an effective treatment for vasomotor symptoms — hot flashes and night sweats. Many women also report improvement in sleep quality, mood stability, concentration, and joint discomfort. Symptom response commonly begins within a few weeks and continues to develop over the first three months.

Bone health

Estrogen contributes to the maintenance of bone density. The decline in estrogen at menopause is associated with accelerated bone loss. Systemic HRT reduces this loss and is recognised as effective for the prevention of postmenopausal osteoporosis.

Genitourinary symptoms

Vaginal dryness, discomfort during intercourse, urinary urgency and recurrent urinary tract infections are associated with reduced estrogen in the genitourinary tissues, a group of symptoms termed genitourinary syndrome of menopause. Both systemic and local vaginal estrogen are used to treat these symptoms; vaginal estrogen is often used where genitourinary symptoms are the primary concern.

Neurologic and Cognitive Benefits

Estrogen receptors are abundant throughout the brain, influencing mood regulation, cognitive function, memory, concentration, and emotional wellbeing. The decline in estrogen at menopause is associated with brain fog, difficulty concentrating, mood changes, and memory concerns—symptoms many women experience as significantly as hot flashes.

Research indicates that systemic HRT can improve cognitive clarity, mood stability, memory recall, and concentration. Many women report improvement in mental sharpness, emotional resilience, and sense of wellbeing within the first few weeks to months of treatment. These neurologic benefits contribute to overall quality of life and functional capacity during the midlife years.

The combined effect of HRT—addressing vasomotor symptoms, bone health, genitourinary function, and cognitive function—demonstrates that hormone replacement therapy acts systemically, producing positive effects throughout the body from head to toe. This whole-body benefit profile is why many women and clinicians consider HRT not simply as symptomatic relief, but as support for overall health and vitality during the menopausal transition.

Risks and Side Effects of HRT

Blood clots and stroke

Oral estrogen is associated with an increased risk of venous thromboembolism. Research indicates that transdermal estrogen does not carry the same increase, which is one reason delivery route forms part of the prescribing discussion. Stroke risk is influenced by age, blood pressure and route of administration.

Common early side effects

In the first weeks to months, some women experience breast tenderness, bloating, nausea, headaches, mood changes or irregular bleeding. These are frequently transient and often resolve or improve with dose or regimen adjustment. Persistent or unexplained bleeding requires investigation.

Types of HRT: Estrogen, Progesterone and Testosterone

Systemic and vaginal estrogen

Systemic estrogen treats symptoms throughout the body. Local vaginal estrogen acts on vaginal and urinary tissues, with minimal systemic absorption at standard doses. Because absorption differs substantially, the two are assessed separately, and vaginal estrogen at standard doses does not require an added progestogen for endometrial protection.

Progesterone and endometrial protection

Estrogen alone stimulates the endometrium. Women who have a uterus are therefore prescribed a progestogen alongside estrogen to protect the endometrial lining. Options include micronized progesterone, synthetic progestins, and a levonorgestrel-releasing intrauterine system.

Body-identical and bioidentical hormone replacement therapy (BHRT)

The term bioidentical is used in more than one way.

Body-identical hormones are regulated, pharmaceutical-grade preparations molecularly identical to the hormones the body produces — typically estradiol and micronized progesterone — manufactured in standardised licensed doses.

Compounded bioidentical hormone replacement therapy (BHRT) describes preparations mixed for an individual patient, sometimes guided by saliva or serum hormone testing, and may combine several hormones in a single preparation. These are prepared individually rather than manufactured in fixed licensed doses.

Both terms appear widely in hormone therapy discussions in the UAE and the United States. Asking which category a specific preparation falls into is a useful part of any consultation.

Delivery methods: patches, gels, sprays, tablets and pellets

Estrogen is available as transdermal patches, gels and sprays, oral tablets, vaginal preparations, and subcutaneous pellets or implants. The options differ in absorption, dosing flexibility, how quickly a dose can be adjusted or stopped, and convenience. Delivery method is generally selected alongside dose during the initial consultation and reviewed at follow-up.

Testosterone in women

Testosterone is produced in women in smaller quantities than in men, but its role in female health is often underappreciated. Women's bodies produce testosterone throughout their reproductive years, with levels declining gradually with age. Contrary to common perception, the female body utilizes testosterone significantly for sexual function, bone density, muscle maintenance, energy levels, and cognitive function.

Testosterone is used in some women alongside estrogen, most commonly where reduced sexual desire, low energy, or diminished motivation persists despite adequate estrogen therapy. It may also be considered where bone density loss is a concern. Beyond sexual health, emerging research suggests testosterone contributes to overall vitality, sense of wellbeing, and physical resilience in midlife and beyond.

Monitoring of testosterone levels forms part of ongoing care, with dosing carefully calibrated to individual needs and response. The decision to include testosterone as part of hormone therapy is made collaboratively, taking into account symptom burden, baseline levels, and individual goals.

Who HRT May Be Suitable For

HRT is generally considered for women experiencing menopausal or perimenopausal symptoms that affect daily functioning and for women with early menopause or premature ovarian insufficiency, where hormone therapy is typically continued at least to the average age of natural menopause.

Suitability depends on symptom burden, age, time since menopause, personal and family medical history, and individual preference regarding treatment.

When HRT Requires Careful Assessment

Certain conditions require detailed evaluation before hormone therapy is considered, and in some cases indicate that HRT is not appropriate.

These include:

• Current or previous hormone-sensitive breast cancer

• Active or recent venous thromboembolism

• Unexplained vaginal bleeding that has not been investigated

• Active liver disease

• Previous stroke or coronary heart disease

• Untreated endometrial hyperplasia

  
  

Some of these are absolute contraindications; others require input from other specialists, or indicate that non-hormonal treatment options should be considered. Non-hormonal approaches to menopause symptoms are also available and may be preferred by some women irrespective of eligibility.

HRT in Dubai: What an Assessment Involves

An assessment for hormone replacement therapy in Dubai typically includes:

• A full symptom history, including cycle pattern and duration of symptoms

• Personal and family medical history, covering breast cancer, blood clots and cardiovascular disease

• Blood pressure, BMI, and up-to-date cervical screening and breast awareness

• Hormone testing

   where clinically indicated. In women over 45 with typical symptoms, menopause is generally diagnosed clinically and blood tests are not always required

• Discussion of hormone type, dose, delivery route and expected timeline

• Scheduled follow-up, commonly at around three months, with review at least annually

• Women relocating to the UAE often arrive without complete medical records. Gathering previous test results, prescriptions and family history before an appointment supports a more complete assessment.

  
  

Frequently Asked Questions About HRT

Is HRT safe?

The risk-benefit balance of HRT depends on age, time since menopause, medical history, the type of hormone used and the route of delivery. Research indicates a more favourable profile for women who begin HRT before age 60 or within ten years of menopause. Suitability is assessed individually.

What are the side effects of HRT?

Common early side effects include breast tenderness, bloating, nausea, headaches, mood changes and irregular bleeding. These are often transient and may improve with dose or regimen adjustment. Persistent or unexplained bleeding requires investigation.

Is the estrogen patch/GEL safer than tablets?

Oral estrogen is associated with an increased risk of venous thromboembolism because it undergoes first-pass liver metabolism. Transdermal estrogen, delivered by patch, gel or spray, largely bypasses this and research indicates it does not carry the same increase.

What is the difference between body-identical and bioidentical hormones?

Body-identical hormones are regulated, pharmaceutical-grade preparations molecularly identical to the body's own hormones, typically estradiol and micronized progesterone, manufactured in standardised licensed doses. Compounded bioidentical hormone replacement therapy describes preparations mixed individually for a patient rather than manufactured in fixed doses.

Do I need progesterone with estrogen?

Women who have a uterus are prescribed a progestogen alongside systemic estrogen to protect the endometrial lining from overstimulation. Women who have had a hysterectomy may take estrogen alone; however, progesterone can also be added when clinically indicated—for example, where bone health, mood stability, or metabolic support is a treatment goal, or where research on specific regimens suggests additional benefit.

Low-dose vaginal estrogen does not require added progestogen at standard doses, as systemic absorption is minimal.

How long can HRT be continued?

There is no fixed maximum duration. Continuation is based on whether benefits continue to outweigh risks for the individual, reviewed at least annually.
