If you have diabetes and experience pain when you move, it might be due to problems with your tendons. Tendons are cord-like bands that connect your muscles to your bones, and high blood sugar levels can contribute to tendon issues. When diabetes is not well-controlled, tendons can thicken and become more prone to tearing. This happens because of substances called advanced glycation end products (AGEs), which form when protein or fat mixes with sugar in your bloodstream. Normally, AGEs form slowly, but high blood sugar speeds up their formation, affecting your tendons. Tendons are made of collagen, and AGEs can change their structure, making them thicker and less capable of handling weight, increasing the risk of tears. Common tendon problems in diabetes include damage to the Achilles tendon, which can limit ankle movement and increase the risk of foot sores. To prevent tendon issues, it's crucial to control your blood sugar through diet, exercise, and medication. Losing weight can also help by reducing pressure on your tendons. If you already have tendon damage, consult your doctor about treatments like physical therapy, medications, or steroid injections. However, be aware that steroids can temporarily raise blood sugar levels. Always discuss the benefits and risks with your doctor.
