Menopausal hormone therapy is the most effective treatment for hot flashes and other vasomotor symptoms.

It may also improve vaginal dryness, urinary symptoms, sleep disturbance, mood changes, and bone loss.

Benefits and risks vary depending on age, time since menopause, medical history, and the type of hormone therapy used. 

 What can menopausal hormone therapy actually improve?

Today, I would like to explain the benefits that have been reported in clinical studies.

Following the publication of the Women’s Health Initiative, or WHI, concerns about hormone therapy became highly prominent. 

However, menopausal hormone therapy remains the most effective treatment for vasomotor symptoms such as hot flashes and night sweats.

1. Relief of Menopausal Symptoms

Estrogen is an effective treatment for vasomotor symptoms and genitourinary changes associated with menopause.

Hormone therapy may reduce hot flashes, anxiety, and irritability while improving sleep disturbances. 

Some women may also notice improvements in mood, fatigue, and overall quality of life.

These benefits often begin to appear within approximately four weeks of starting treatment, 

although some women may need more time to notice a difference.

2. Improvement in Vaginal and Urinary Symptoms

As estrogen levels decline, the vaginal lining may become thinner, drier, and more vulnerable to irritation. 

This can lead to vaginal dryness, discomfort, recurrent inflammation, or pain caused by friction.

Hormone therapy can help restore the vaginal environment by improving the thickness and blood supply of the vaginal lining.

 It may also increase natural vaginal lubrication.

Estrogen treatment may help maintain a healthy vaginal pH and support the growth of beneficial bacteria such as Lactobacillus.

It may also reduce recurrent urinary tract infections and relieve urinary symptoms such as urgency and frequency in some women.

3. Skin, Muscle and Joint Health

Estrogen plays a role in maintaining collagen, skin thickness, and elasticity. 

Some studies suggest that hormone therapy may help reduce certain changes associated with skin aging, 

although it should not be prescribed solely as an anti-aging treatment.

Some women also experience joint or muscle discomfort during menopause. 

Hormone therapy may help relieve these symptoms in certain cases, but individual responses can vary.

Changes in estrogen levels may also affect oral health, contributing to dry mouth, a burning sensation, gum inflammation, or bleeding gums. Some studies have suggested that hormone therapy may have beneficial effects on these symptoms, but further evidence is needed.

Changes in the voice can also occur after menopause. Some reports suggest that women receiving hormone therapy may experience fewer voice-related changes, although this is not a primary indication for treatment.

4. Prevention of Bone Loss and Osteoporosis

Hormone therapy helps protect against the rapid bone loss that can occur during the early years after menopause.

It can therefore reduce the risk of osteoporosis and related fractures.

Timing is important.

For women experiencing menopausal symptoms, the benefit-risk profile is generally more favorable when treatment begins before age 60 or within 10 years of menopause, provided there are no contraindications.

However, systemic hormone therapy is not usually started after age 60 or more than 10 years after menopause solely for the purpose of protecting the bones.

5. Cardiovascular and Cognitive Health

Estrogen affects blood vessels and may support vascular function when treatment is started around the time of menopause. 

However, study findings regarding cardiovascular disease have not been consistent.

Large studies such as WHI, HERS, and WELL-HART did not show that hormone therapy prevented coronary artery disease. 

Other studies, including KEEPS and ELITE, have explored whether the timing of treatment may influence cardiovascular outcomes.

Therefore, hormone therapy should not be started solely to prevent heart disease. Current recommendations advise against using systemic hormone therapy for the primary prevention of chronic diseases in otherwise asymptomatic postmenopausal women. 

The relationship between menopausal hormone therapy and cognitive function also remains uncertain.

Some observational studies have reported a lower incidence of Alzheimer’s disease among women who used hormone therapy for an extended period. However, these findings do not prove that hormone therapy prevents dementia. Hormone therapy is not currently recommended for preventing or treating cognitive decline or dementia.

6. Colorectal Cancer Findings

In the WHI trial, combined estrogen and progestogen therapy was associated with a lower incidence of colorectal cancer during the study period.

However, hormone therapy should not be prescribed specifically to prevent colorectal cancer because its overall benefits and risks must be considered together. The USPSTF recommends against using hormone therapy solely for the primary prevention of chronic medical conditions. 

Around the age of 50, many women begin to wonder:

“Should I take hormones, or should I simply wait and see?”

There is no single answer that applies to everyone. The decision should take into account your symptoms, age, time since menopause, whether you have a uterus, and your personal and family medical history.

Menopausal hormone therapy can be highly effective when prescribed to the right patient at the appropriate time. 

I hope today’s explanation helps you better understand its potential benefits and make an informed decision with your OB-GYN.
