Research presented at the 2024 Annual Meeting of The Menopause Society in Chicago has focused on the impact of hormone replacement therapy (HRT) on various aspects of health. One study revealed that extended use of certain hormone therapies can improve markers of cardiovascular health during menopause. Another study found that hormone therapy can enhance insulin sensitivity by restoring estrogen levels in the body. As estrogen levels tend to decrease with age, leading to symptoms associated with menopause, debates persist about the safety and long-term effects of HRT.
A study presented at the meeting, led by researchers from Penn State Hershey Medical Center, utilized data from the Women’s Health Initiative (WHI) to compare cardiovascular health biomarkers in participants on certain estrogen-based hormone therapies versus a placebo. The findings indicated that those on conjugated equine estrogens experienced a 13% increase in high-density lipoprotein cholesterol (HDL-C), also known as “good cholesterol.” Furthermore, those taking medroxyprogesterone acetate in addition to estrogen saw improvements in cholesterol levels as well as markers of insulin resistance, with minimal impact on triglyceride levels.
Researchers have highlighted the importance of estrogen in maintaining cardiovascular health after menopause. Estrogen helps to maintain artery elasticity, reduce bad cholesterol levels, and increase good cholesterol production in the body. The Penn State Hershey Medical Center study demonstrated that estrogen replacement therapy can restore these benefits, promoting heart health in menopausal individuals. It is recommended to consider starting estrogen therapy at the onset of menopause for optimal cardiovascular benefits.
Additionally, a review and meta-analysis presented by researchers from Reading Hospital Tower Health and Drexel University College of Medicine suggested that HRT was associated with improved insulin sensitivity in postmenopausal women. Studies, whether administered orally or transdermally, were linked to enhanced insulin sensitivity, potentially offering protection against diabetes. Estrogen and progesterone medications within HRT were found to regulate insulin production, maintain body weight, redistribute fat, and decrease the risk of type 2 diabetes.
While HRT has shown promising results in improving cardiovascular and metabolic health in menopausal individuals, it is essential to consider individual differences and potential side effects. Different types of HRT may affect individuals in varying ways, with some therapies potentially increasing the risk of blood clots, strokes, or breast cancer. Physicians recommend selecting the lowest effective dose of HRT to manage menopausal symptoms while minimizing potential risks based on individual health profiles and concerns. Women at risk for osteoporosis may benefit from HRT, which has been shown to prevent bone loss and fractures.
Ultimately, discussions around the long-term health impacts of HRT for menopausal symptoms continue, including considerations for breast cancer risk, heart health support, brain health, and the use of specific HRT formulations. Medical advice tailored to the individual’s situation is crucial in deciding whether to pursue HRT and what form of treatment to pursue. Consulting with healthcare providers to address questions and concerns about HRT can facilitate informed decision-making for personal health and well-being.
