Menopause is a significant life phase for women that brings about hormonal changes affecting various parts of the body. For years, hormone replacement therapy, calcium and vitamin D supplementation, and low-fat diets have been used as preventive treatments for postmenopausal women to reduce the risk of certain diseases. However, a new study from the Women’s Health Initiative challenges the effectiveness of these treatments in preventing cardiovascular disease, fractures, and cancer.
The researchers found that hormone replacement therapy did not support preventing cardiovascular disease, stroke, dementia, or other chronic diseases. While it did help reduce vasomotor symptoms such as hot flashes, it also significantly increased the incidence of breast cancer. The study included 161,808 women ages 50 to 79 over a 20-year follow-up period, noting that many postmenopausal women worldwide have used these therapies to improve their health.
Calcium and vitamin D supplementation were found to not prevent fractures in postmenopausal women, with the study recommending that women not meeting national dietary guidelines might benefit from taking supplements. Additionally, the low-fat diet followed by participants did not significantly decrease the incidence of breast or colorectal cancer. However, long-term follow-up showed a reduction in breast cancer mortality, suggesting that this diet may be an option for women looking to lower their risk of death due to breast cancer.
Dr. Nicole Weinberg, a cardiologist from California, emphasized the importance of using hormone therapy for symptom relief rather than for preventive measures against cardiovascular disease. She stated that the data from the study provided helpful information for treating women in different stages of menopause. Dr. Cheng-Han Chen, an interventional cardiologist, noted that recent studies did not support the use of hormone replacement therapy for heart disease prevention, recommending heart-healthy lifestyle changes instead.
While the researchers acknowledged limitations in their study, such as not being able to distinguish the effects of reducing fat from increasing fruits, vegetables, and grains in the low-fat diet, they provided valuable insights into the effectiveness of common menopausal treatments. As findings continue to evolve, it is essential for healthcare providers to consider individualized approaches to treating women going through menopause, recognizing the unique challenges and risks associated with this life phase.
