You might not realize it, but some early signs of a serious health issue can actually show up in your feet.

Experts are urging people to be aware of unusual foot-related symptoms that could point to a potentially dangerous condition. Diabetes — a long-term illness that causes abnormally high blood sugar levels — is one such condition.

While the exact cause of type 1 diabetes is still unknown, type 2 diabetes is often associated with lifestyle factors like excess weight and lack of physical activity, though it can also be hereditary.

As with any medical condition, identifying symptoms early allows for quicker access to treatment. However, some of these warning signs may show up in places you wouldn’t expect.

Because of raised blood sugar levels, the feet are one part of the body that can suffer significant damage. Diabetes UK explains: “Over time raised blood sugar levels, also known as blood glucose levels, can damage the small blood vessels that supply the nerves in your feet.
