What's Happening?
Recent findings have raised concerns about the potential adverse effects of weight-loss injections, which are used by approximately 2.5 million people in the UK. These injections, while known for their benefits such as reducing the risk of death in heart
patients, have been linked to a significant reduction in lean body mass, including muscle. This reduction is particularly concerning for middle-aged and older individuals, as it may increase the risk of frailty and falls. A review led by Dr. Gillian Hatfield from the University of the Fraser Valley in Canada highlights that the loss of lean body mass from these injections is comparable to the effects of bariatric surgery, cancer treatment, or a decade of aging. The report, commissioned by fitness company Les Mills, emphasizes the importance of incorporating strength training exercises to mitigate these risks.
Why It's Important?
The implications of these findings are significant for public health, particularly for older adults who are already at risk of muscle and bone mass loss due to aging. The potential increase in frailty and fall risk could lead to higher healthcare costs and a greater burden on medical services. Additionally, the findings suggest a need for a coordinated effort among the government, health sector, and fitness industry to provide better support and guidance for individuals using weight-loss medications. This could involve promoting strength training and physical activity as essential components of weight-loss programs to preserve muscle mass and overall health.
What's Next?
The review calls for a collaborative approach to address the potential risks associated with weight-loss injections. This includes recommendations for individuals taking these medications to engage in regular strength training exercises and accumulate at least 150 minutes of moderate to vigorous physical activity per week. Such measures could help maintain muscle mass and reduce the likelihood of weight regain after treatment. The findings may prompt further research into the long-term effects of weight-loss medications and the development of comprehensive guidelines to ensure safe and effective weight management strategies.
