Hormone therapy comes with risks and is generally not recommended for women over 60. However, for those who qualify, it may significantly help reduce menopausal symptoms.
Hormone replacement therapy involves taking a medication when your hormone levels drop. It contains:
- estrogen (or estradiol, the most common form of the hormone in your body)
- progesterone
- or both of these hormones
HRT has a controversial history. Popularized in the 1960s as a way to stay youthful after menopause, HRT use peaked in the 1990s.
Then, in 2002, a study undertaken by the Women’s Health Initiative (WHI) linked HRT to cancer and cardiovascular disease. After the WHI’s report was published, HRT use in the United States, the UK, and Canada dropped dramatically.
The WHI report has since been called into question. Newer studies have shown that HRT has lower risks and more benefits for women who start treatment before age 60 and within 10 years of menopause.
However, many people are still hesitant to use HRT because of concerns about the risks it could pose.
Although there’s still confusion about HRT, many researchers say the benefits outweigh the risks. Let’s look at some of the best-researched benefits of HRT.
Alleviates menopause symptoms
The experience of menopause is different for everyone. Some people have symptoms that are so mild no medical treatment is needed.
For others, the symptoms can be so severe that it interferes with their ability to go about their daily life. In this situation, it’s usually a good idea to talk with a doctor about hormone replacement.
HRT may help ease menopause symptoms in the following ways:
Low dose estrogen
- Relieves vasomotor symptoms, such as hot flashes and not sweats
- Relieves genital and urinary symptoms, such as vaginal dryness, painful sex, and urinary problems.
Pasterone and Ospemifene
Offers protection against cardiovascular disease
Numerous studies have confirmed that when HRT is started early, within 10 years of menopause, it can help protect your heart and vascular system from disease.
Before starting HRT, it’s important to undergo a physical exam to be sure you don’t already have signs of cardiovascular disease. Your doctor will likely want you to have a checkup every year while you’re on HRT to be sure you’re maintaining good heart health.
Helps ease depression
During the transition into menopause, which can last several years, many women experience depression.
Although depression is most commonly treated with antidepressants, research has found that hormone therapy with estrogen may be a more effective treatment option for managing depressive symptoms in menopausal women.
Helps protect your bones
Menopause increases the risk of bone loss, osteoporosis, and fractures.
Research shows that 1 to 2 years of estrogen-based HRT in the form of a skin patch may help improve bone density and protect the structure of your bones as you get older.
Prevents loss of muscle mass
As you age, you tend to lose muscle mass. You need muscle mass for mobility, strength, and balance.
HRT can help prevent the loss of muscle. When combined with exercise, HRT may help increase muscle mass and strengthen your muscles.
May help prevent Alzheimer’s disease and Parkinson’s disease
According to a 2020 meta-analysis, estrogen-based HRT may have a protective effect against some neurological conditions.
In particular, it may play a role in decreasing the risk of Parkinson’s disease and Alzheimer’s disease.
Women under the age of 60, or who entered menopause in the last 10 years, stand to benefit most from hormone therapy.
For older than 60, or women who started menopause more than 10 years ago, the risks could outweigh the benefits.
When the Women’s Health Initiative published its report in 2002, doctors and patients began avoiding HRT out of concern that it could do more harm than good.
Although newer research has allayed some of those fears, there are still some risks to consider when deciding if HRT is right for you.
A higher risk of certain cancers
A 2020 study found that past use of HRT was linked to a higher risk of breast cancer. This elevated risk was associated with both estrogen-only and combined therapies.
A 2017 study also found that hormone therapy, particuarly oestrogen plus progestin MHT (EP-MHT), may increase ovarian and endometrial cancer, but decrease the risk of all gastroinestinal cancer.
More research is needed to understand the link between HRT and cancer risk.
Can increase the risk of blood clots
Studies have shown that HRT (in pill and patch forms) may raise your risk of blood clots and stroke. This risk may be highest for people over 60 or who started menopause over a decade ago. The longer you take HRT, the greater the increase in your risk.
Because of this risk, health experts recommend the lowest possible HRT dose for the shortest period of time for people over 60 or who are 10 years past the onset of menopause.
Raises the risk of gallbladder disease
Since estrogen builds up the concentration of cholesterol in the gall bladder, using HRT increases the likelihood of gallstones.
The risk is highest for women who use HRT longer than 5 years.
The Food and Drug Administration (FDA) has approved several categories of HRT. They include:
- estrogen-only products
- progesterone-only products
- products that combine estrogen and progesterone
- products that combine estrogen with other medications
These hormone medications come in several different forms, such as:
- pills – examples include:
- Cenestin, Enjuvia, Estrace, Femtrace, Menest, Ortho-Est, Premarin (estrogen)
- Prometrium, Provera (progesterone)
- Activella, Femhrt, Prefest, Prempro (estrogen and progesterone)
- Duavee (combination estrogen and hormone medicine)
- patches – such as:
- Alora, Climara, Estraderm, Minivelle, Vivelle (estrogen)
- Climara Pro, Combipatch (estrogen and progesterone)
- injections – such as:
- Delestrogen, Premarin (estrogen)
- skin cream/spray – such as:
- Estrasorb, Evamist, Premarin (estrogen)
- vaginal rings or creams – such as:
- Estrace, Femring, Ogen, Premarin (estrogen)
Creams and rings supply hormones to a localized area, which help to limit the amount in your system.
According to the FDA, you may want to avoid taking HRT if you’ve had:
- problems with vaginal bleeding
- breast cancer or uterine cancer
- blood clots
- a heart attack or stroke
- a bleeding disorder
- liver disease
- allergic reactions to medications containing hormones
Talk with your doctor about whether estrogen is right for you, if you have:
- a history of smoking
- gallbladder disease
- ovarian cancer
- migraine headache
- seizure disorder
- high blood pressure
- endometriosis
- hyperlipidemia (excess fat in your blood)
- uterine fibroids
If you don’t want to use HRT to treat the symptoms of menopause, you might have some success with a non-hormonal treatment.
Some options that may help reduce the severity and frequency of hot flashes include:
- medication such as selective serotonin reuptake inhibitors (SSRIs) or gabapentin
- black cohosh supplements
- acupuncture treatment
- foods such as soy milk, edamame, and other soy foods
- purified pollen
Talking about menopause symptoms can be uncomfortable, especially when the symptoms feel personal.
It may help to make a list of your concerns in advance, so you can refer to the list if you forget.
Tell your doctor about:
- any health conditions such as cancer, heart problems, liver disease, or blood clots
- whether or not you’ve ever smoked
- medications you’re taking for other conditions
- allergies
- side effects you’ve had from other hormonal treatment
While menopause is a natural change, it does involve a drop in your estrogen levels. This can trigger various symptoms which, in some cases, can be severe.
Hormone replacement therapy (HRT) may help ease many symptoms of menopause, including hot flashes and vaginal dryness. It may also lower your risk of heart problems, protect your bones and muscles, and reduce depression.
HRT, however, is not without its risks, especially for women over 60 or who started menopause more than 10 years ago.
Talk with a healthcare professional about whether HRT is right for you and whether the benefits outweigh any potential risks.
