Managing diabetes involves keeping an eye on many different aspects of health, from blood glucose levels to kidney function. But did you know that the amount of muscle you have could also play a role in protecting your eyes? A recent study published in the scientific journal, ‘scientific reports’ in July 2024 explored how muscle mass, as measured by CER (Creatinine Excretion Rate), might be connected to diabetic retinopathy—a common eye problem in people with diabetes.

      Diabetic retinopathy is a condition where high blood glucose levels damage the blood vessels in the retina, the light-sensitive part of the eye. This can lead to vision problems and even blindness if not managed properly. It’s more likely to occur in people who have had diabetes for a long time, those with poor blood glucose control, and those with high blood pressure.

      Your muscles do more than just help you move—they also play a crucial role in managing how your body handles glucose. The more muscle mass you have, the better your body is at using insulin to keep blood glucose levels stable. This study looked at 2,035 people with type 2 diabetes to see if there was a link between muscle mass and the risk of developing diabetic retinopathy. Researchers used CER to estimate muscle mass in these individuals. CER, or Creatinine Excretion Rate, is a measure of how much creatinine—a waste product produced by muscles—is being removed from your body through urine. Because creatinine levels are closely related to muscle mass, CER is often used as an indicator of how much muscle you have.

      Researchers found that people with higher CER levels, indicating more muscle mass, had a lower risk of developing diabetic retinopathy. Even after taking into account other risk factors like age, how long someone had diabetes, and their blood glucose levels, the link between CER and eye health remained strong.

      Interestingly, the study also found that this relationship was independent of body weight. In other words, whether someone was heavier or lighter didn’t change the fact that higher CER, and thus more muscle mass, was linked to better eye health.

      These findings suggest that maintaining muscle mass might be an important part of managing diabetes and protecting your eyes. Regular exercise, especially strength training along with cardio, could help build and preserve muscle, potentially reducing the risk of complications like diabetic retinopathy.

      While keeping the blood glucose in check is crucial for preventing diabetic retinopathy, this study highlights the importance of also paying attention to the muscle mass. Regular physical activity, especially exercises that build muscle, might not just keep you fit—it could also help protect your vision!
