Collapsed structures can’t do their jobs. Think of a bridge that has fallen down. It can’t help you cross a river, stream, or any other obstacle in your way. A fallen-in roof doesn’t protect you from bad weather. Collapsed and flattened tires won’t roll correctly, if at all. A limb suffering from a diabetic foot collapse, called Charcot foot, won’t function correctly, either.
How Diabetes Can Break Down Your Arches
Diabetes is a serious systemic condition that damages blood vessels and impairs nerve functions. Elevated blood sugars deteriorate your body’s tissues, weakening them significantly and making them more susceptible to problems. Your feet have a particularly high risk for this, since they have a naturally weak circulation. The nerve damage this causes means your lower limbs are far less sensitive to pain than normal, too. You could easily develop an injury and never feel it. You could continue walking on damage and make the problem worse without realizing it as well.
This is how Charcot foot develops. As an extreme complication of diabetes, the bones in the feet slowly break down, collapsing the arch. Out-of-control blood sugar levels weaken the bones in your feet and make them prone to tiny fractures. Because the impaired nerves in your lower limbs are deadened or misfire frequently, you can’t feel the bone damage. You continue walking, making these little fractures worse and breaking down the bone tissue. Eventually, your arch and even your ankle can collapse and deform.
