For many healthy adults, replacing these levels of hormones in the body through HRT can provide relief during the menopausal phase. HRT is prescribed with caution, as risks may include an increased chance of developing serious conditions like breast cancer and heart disease in certain people.
This article discusses the different types of HRT available for treating menopause symptoms and outlines the potential benefits and risks.
Types of Hormone Replacement Therapy
Hormone replacement therapy is made with either one or two types of hormones:
Estrogen only, which helps reduce night sweats, hot flashes, vaginal dryness, and urinary discomfort, in addition to bone loss that’s associated with aging, and is recommended for people who have had their uterus removed (hysterectomy) Estrogen with added progesterone, which helps protect against the risk of endometrial cancer in people who still have a uterus
Each is available in different formulas and dosages.
Systemic Hormone Therapy
Systemic therapies allow the hormones—whether estrogen alone or with added progesterone—to circulate throughout the body via the bloodstream. This method impacts the vasomotor symptoms (night sweats and hot flashes) of menopause.
Systemic HRT is provided in the following ways:
Pill formulas that are taken orally (by mouth)Topical formulas that absorb through the skin via a patch, gel, or spray Vaginal rings that are inserted into the vagina every few months
Low-Dose Vaginal Products
Low-dose vaginal therapies release smaller amounts of hormones to the affected area through placement into the vagina.
Because they work locally instead of systemically, these products are typically used to just treat menopause symptoms that affect the vagina or urinary tract, such as vaginal dryness. They do this by helping to thicken vaginal tissues and boost moisture.
Low-dose HRT is available in the form of a vaginal cream, ring, or tablet. They most often contain estrogen alone.
Benefits of Hormone Replacement Therapy
For many healthy adults who are experiencing moderate or severe menopausal symptoms, there are benefits to using hormone replacement therapy that may override potential risks of this treatment.
Medical experts note that the benefits of HRT can include:
Relief from moderate to severe hot flashes Relief from vaginal dryness and discomfort Prevention of bone loss (osteoporosis) and bone fractures Protection against colorectal cancer
In addition, the American College of Obstetrics and Gynecologists (ACOG) notes that otherwise healthy people who are experiencing early menopause or estrogen deficiency may find HRT beneficial.
Risks of Hormone Replacement Therapy
Many medical experts agree that hormone replacement therapy is an option worth considering for healthy adults under 60 seeking to manage certain menopausal symptoms. But it’s important to point out that research has highlighted several potentially serious risks of using HRT.
In particular, research that began in 2002 raised significant concerns, including that some participants on HRT had a higher risk of breast cancer, heart disease, stroke, blood clots, urinary incontinence, gallbladder disease, and dementia. The affected participants were mostly over the age of 60 and past the menopausal stage.
Since then, researchers have continued to analyze these findings as they explore the long-term safety of HRT. Experts have clarified that the potential risks may be more likely in people who:
Begin HRT at age 60 or olderBegin HRT more than 10 years after the start of menopauseHave a personal or family history of conditions like cancer and heart disease
Anyone with these risk factors will not be considered a candidate for hormone replacement therapy.
To help avoid further risks in people who are prescribed HRT, the U.S. Food and Drug Administration (FDA) recommends using HRT at the lowest working dose for the shortest period of time possible, which is typically no longer than five years.
What to Expect
Just as the transition to menopause is unique for every individual, the experience of taking hormone replacement therapy will be, too.
May be pregnantHave issues with abnormal vaginal bleedingHave a family or personal history of breast cancerHave a personal history of heart disease, stroke, blood clots, or liver diseaseHave a family history of gallbladder diseaseAre allergic to estrogen or progesterone
Like most medications, there are some common side effects that may occur with HRT, including:
Irregular bleeding or spotting Breast tenderness Headaches Bloating Nausea and vomiting Hair loss Vaginal yeast infection
Note that potential side effects can vary based on the type of hormone replacement therapy and dosage. If side effects become bothersome, talk to your healthcare provider before stopping medication.
Summary
Hormone replacement therapy (HRT) is a medical treatment that boosts declining levels of estrogen and progesterone in a person approaching menopause. It helps ease some menopausal symptoms, such as hot flashes, night sweats, and vaginal dryness. HRT can be used orally, topically, or vaginally.
While the benefits of HRT can be worthwhile for people looking for moderate to severe symptom relief, studies have shown that it comes with an increased chance of breast cancer, heart disease, and other serious health conditions. It’s important to talk to a healthcare provider about your medical history and personal risks before deciding whether HRT is right for you.
A Word From Verywell
The transition to menopause often comes with physical and emotional challenges, but your quality of life does not have to suffer. Whether or not you decide to try hormone replacement therapy, know that there are other options to help you cope with the menopausal transition, including non-hormonal medications that can help with hot flashes and vaginal discomfort.
