Understanding Hormone Therapy During Perimenopause and Menopause

HRT for Women: Benefits, Risks & Who May Be a Candidate

Hormonal changes during perimenopause and menopause can affect much more than menstrual cycles. Some women notice hot flashes, night sweats, sleep problems, mood changes, vaginal dryness, difficulty concentrating, or changes in sexual health.

For women with bothersome symptoms, menopausal hormone therapy—often called HRT—may be one treatment option.

HRT is not right for everyone, and treatment should be individualized based on symptoms, age, medical history, personal risk factors, and treatment goals.

What Is Hormone Replacement Therapy?

Menopausal hormone therapy replaces some of the hormones that naturally decline during the menopause transition, primarily estrogen and, when needed, progesterone or another progestogen.

Systemic hormone therapy can be delivered through:

• Tablets
• Skin patches
• Gels or sprays
• Certain vaginal rings
• Pellet Therapy

There are also low-dose vaginal estrogen treatments designed primarily for vaginal and urinary symptoms.

The type of therapy recommended depends partly on whether a woman still has her uterus.

Women who still have a uterus generally need a progestogen along with systemic estrogen to help protect the uterine lining. Women who have had a hysterectomy may be able to use estrogen alone. The Menopause Society

What Symptoms Can HRT Help?

Hormone therapy is considered one of the most effective treatments for bothersome menopausal hot flashes and night sweats. The Menopause Society

Treatment may help women experiencing symptoms such as:

Hot Flashes and Night Sweats

These are among the most common symptoms of menopause and can significantly disrupt work, sleep, and everyday activities.

Systemic estrogen therapy is highly effective at reducing vasomotor symptoms such as hot flashes and night sweats. The Menopause Society

Sleep Problems

Night sweats can repeatedly interrupt sleep. Improving vasomotor symptoms may therefore improve sleep for some women.

However, sleep problems can also result from sleep apnea, anxiety, medications, stress, thyroid disease, and other medical conditions.

Vaginal Dryness and Discomfort

Declining estrogen can lead to vaginal dryness, irritation, discomfort during intercourse, and urinary symptoms.

This collection of symptoms is commonly called genitourinary syndrome of menopause, or GSM.

Low-dose vaginal estrogen is one treatment option for women whose symptoms are primarily vaginal or urinary. The Menopause Society

Sexual Health

Menopause-related vaginal dryness, discomfort, sleep disruption, and hormonal changes can contribute to changes in sexual health and libido.

A thorough evaluation is important because sexual symptoms often have multiple contributing factors.

Mood and Concentration Changes

Some women describe:

• Irritability
• Mood changes
• Difficulty concentrating
• “Brain fog”
• Feeling less like themselves

These symptoms can occur during the menopause transition, although they may also result from sleep disruption, stress, anxiety, depression, medication effects, thyroid disease, anemia, and other conditions.

Who May Be a Good Candidate for HRT?

There is no single profile that determines whether someone should receive hormone therapy.

For many healthy women with bothersome menopausal symptoms, the benefit-risk profile is generally considered most favorable when treatment is started before age 60 or within approximately 10 years of menopause onset. The Menopause Society

A woman may consider discussing hormone therapy with her provider if she has:

• Moderate or severe hot flashes
• Significant night sweats
• Menopause-related sleep disruption
• Vaginal or urinary symptoms
• Menopause symptoms that are interfering with quality of life
• Premature menopause or early loss of ovarian function
• Symptoms that have not responded adequately to other approaches

The decision ultimately depends on the individual's symptoms, health history, risk factors, and preferences.

What Are the Potential Benefits?

Potential benefits can include:

Significant Reduction in Hot Flashes

Hormone therapy is among the most effective treatments available for vasomotor symptoms. The Menopause Society

Improved Night Sweats and Sleep

Reducing overnight vasomotor symptoms may lead to more restful sleep.

Improvement in Vaginal Symptoms

Estrogen therapy can help address vaginal dryness and other symptoms associated with GSM.

Bone Protection

Systemic menopausal hormone therapy can reduce bone loss and fracture risk while it is being used. FDA-approved indications for menopausal hormone therapy include treatment of menopausal symptoms and prevention of postmenopausal osteoporosis. USPSTF

However, hormone therapy generally should not be started solely to prevent chronic diseases in otherwise asymptomatic postmenopausal women. The USPSTF recommends against using menopausal hormone therapy specifically for the primary prevention of chronic conditions. USPSTF

What Are the Risks of HRT?

HRT is not risk-free.

The degree of risk depends on several factors, including:

• Age
• Time since menopause
• Whether estrogen is used alone or with a progestogen
• Route of administration
• Dose
• Duration of treatment
• Personal and family medical history

Potential risks may include:

Blood Clots

Oral hormone therapy can increase the risk of venous blood clots. The Menopause Society

The risk profile may differ depending on how the hormone is administered, which is one reason treatment should be individualized.

Stroke

Both estrogen alone and combined estrogen-progestogen therapy may increase stroke risk. The Menopause Society

The absolute risk for an individual woman depends significantly on her age and underlying health.

Breast Cancer

Breast cancer risk differs depending on the specific treatment regimen.

Combined estrogen and progestogen therapy has been associated with an increased breast cancer risk with longer use in major clinical studies. Risks with estrogen-alone therapy after hysterectomy differ from those of combined therapy. USPSTF

This is why a patient's breast cancer history, screening history, family history, and other risk factors should be considered before treatment.

Uterine Cancer

Estrogen given by itself can stimulate the uterine lining.

For women who still have a uterus, systemic estrogen is generally combined with adequate progesterone or another progestogen to protect against endometrial hyperplasia and cancer.

Gallbladder Disease

Systemic hormone therapy may increase the risk of gallbladder disease in some women. USPSTF

Who May Not Be a Good Candidate?

Systemic hormone therapy may not be appropriate for women with certain medical histories.

According to The Menopause Society, important contraindications or reasons for additional caution can include:

• Previous or current breast cancer
• Certain uterine cancers
• Unexplained vaginal bleeding
• Significant liver disease
• Previous blood clots
• Certain cardiovascular diseases The Menopause Society

This does not mean every woman with a complicated medical history has the same treatment options. For example, local vaginal treatments may sometimes be considered differently from systemic therapy.

Your provider should evaluate your individual circumstances.

Does HRT Cause Weight Gain?

This is a common concern.

Weight gain frequently occurs during midlife because of aging, changing body composition, activity level, sleep disruption, and metabolic changes.

However, menopausal hormone therapy itself has not been shown to cause the typical midlife weight gain many women experience. The Menopause Society

Nutrition, resistance training, cardiovascular exercise, adequate protein intake, sleep, and metabolic health remain important regardless of whether hormone therapy is used.

Do You Need Hormone Testing Before Starting HRT?

Not necessarily.

For women in the typical age range with classic perimenopausal or menopausal symptoms, menopause is often diagnosed clinically based on symptoms, menstrual history, age, and medical history.

Hormone levels can fluctuate considerably during perimenopause, so a single estrogen or FSH measurement may not always provide useful information.

However, laboratory testing may be appropriate when symptoms are atypical, menopause occurs unusually early, or another medical condition is suspected.

Depending on the patient's presentation, evaluation may include tests for conditions such as:

• Thyroid disease
• Anemia
• Vitamin deficiencies
• Diabetes or insulin resistance
• Other endocrine conditions

What About “Bioidentical” Hormones?

The term bioidentical hormone is often used in marketing, but it can mean different things.

Several FDA-approved estradiol and progesterone products are chemically identical to hormones produced by the human body.

These should be distinguished from custom-compounded hormone preparations.

Compounded hormones may be appropriate in selected circumstances, such as when a patient cannot tolerate an FDA-approved formulation, but they do not undergo the same standardized FDA approval process for safety, effectiveness, dose consistency, and manufacturing quality.

Patients should discuss the advantages and limitations of different formulations with their healthcare provider.

How Long Can a Woman Stay on HRT?

There is no universal cutoff that applies to every woman.

Treatment duration should be individualized.

Some women use therapy for several years and then gradually discontinue it. Others continue treatment longer because symptoms persist and their individual benefit-risk profile remains favorable.

The Menopause Society notes that there is no single mandatory age or duration at which all women must discontinue hormone therapy. Periodic reevaluation of benefits and risks is important. The Menopause Society

Is HRT Only for Women Who Have Completed Menopause?

No.

Many of the most disruptive symptoms—including hot flashes, night sweats, menstrual changes, sleep problems, and mood symptoms—begin during perimenopause, sometimes years before the final menstrual period.

Treatment options during perimenopause may differ depending on:

• Menstrual patterns
• Need for contraception
• Symptoms
• Medical history
• Pregnancy potential
• Individual risk factors

What Happens During a Hormone Health Evaluation?

At Z-2-H Family Med & Urgent Care Clinic, an evaluation can begin with a comprehensive review of your symptoms and overall health.

Your provider may discuss:

• Menstrual and menopause history
• Hot flashes and night sweats
• Sleep
• Mood
• Sexual health
• Vaginal and urinary symptoms
• Current medications
• Personal and family history
• Cardiovascular risk factors
• Breast and gynecologic history
• Bone health
• Appropriate laboratory testing when indicated

From there, you and your provider can discuss whether hormone therapy or another treatment approach may be appropriate.

HRT Should Be Personalized

Hormone therapy is neither automatically appropriate nor automatically inappropriate simply because a woman is going through menopause.

The important question is:

What are your symptoms, what are your individual risks, and what treatment approach provides the best balance of benefit and risk for you?

For many appropriately selected women with significant menopausal symptoms, hormone therapy can provide substantial relief. For others, non-hormonal therapies or more targeted treatments may be a better option.

Ready to Discuss Your Symptoms?

If hot flashes, night sweats, poor sleep, vaginal symptoms, changes in sexual health, or other menopause-related concerns are affecting your quality of life, schedule a hormone health consultation with Z-2-H Family Med & Urgent Care Clinic.
