A study conducted by researchers at Korea University College of Medicine has revealed that women who undergo early or premature menopause face a significantly higher risk of developing type 2 diabetes. The findings highlight menopause as a critical factor in women’s health, particularly in relation to metabolic conditions like diabetes.
Type 2 diabetes, a chronic illness associated with severe complications such as heart disease and premature death, is influenced by a variety of factors, including genetics, obesity, and lifestyle. However, this study, led by Associate Professor Ga Eun Nam, emphasizes the role of menopause, particularly its timing, in determining the likelihood of developing type 2 diabetes.
Menopause, which signals a major hormonal shift, is known to affect metabolism, insulin sensitivity, and glucose regulation. Although the effects of estrogen on these processes are well-established, the connection between the timing of menopause and diabetes risk had not been fully understood until now.
In an effort to explore this relationship, the team from Korea University analyzed the health data of over 1.1 million postmenopausal women in South Korea. The study, published in JAMA Network Open on January 21, 2025, uncovered that women who experience premature menopause—defined as menopause before the age of 40—face an increased risk of type 2 diabetes. The study also found that this risk escalates as the age of menopause onset decreases.
The researchers discovered that women who went through menopause before 40 had a notably higher chance of developing diabetes compared to those who underwent menopause at or after the typical age of 50. This pattern underscores the significant impact of hormonal changes on metabolic health.
Professor Nam explained that estrogen’s role in maintaining insulin sensitivity and regulating glucose metabolism may be crucial in this increased risk. “Women with premature or early menopause may be at a higher risk for type 2 diabetes compared to others, making it vital to focus on maintaining a healthy weight and lifestyle, including regular physical activity and a balanced diet,” she said.
The study also emphasizes the importance of early diagnosis and intervention. The researchers recommend that women with early or premature menopause undergo regular health check-ups and lifestyle changes to mitigate the risk of developing diabetes. “It’s essential to address this issue early through proactive health screenings,” added Prof. Nam.
This comprehensive study contributes valuable insights into how menopause timing affects women’s long-term health and suggests that more targeted screening and prevention efforts could be beneficial. Prof. Nam further stated, “Research linking premature menopause to an increased risk of type 2 diabetes could revolutionize healthcare in the next decade by informing clinical practices, guiding targeted prevention programs, and equipping women with the knowledge they need to manage their health.”
Overall, the study highlights the importance of recognizing menopause as a significant life stage that can influence women’s metabolic health, urging healthcare systems to adapt and consider this transition in their approaches to diabetes prevention and management.
