What is diabetes and its complications?

Diabetes is a chronic disease characterized by elevated blood glucose levels. There are two main types: type 1 diabetes, which occurs when the body does not produce insulin, and type 2 diabetes, which develops when the body does not use insulin effectively. Complications can include problems with the eyes, kidneys, nerves, and heart.

Early warning signs

It is crucial to identify warning signs that may indicate complications. Some symptoms to watch for include: blurred vision, numbness or tingling in the hands and feet, wounds that do not heal, frequent infections, and changes in the skin.
