Diabetes develops because of defects in the glucose production inside our bodies. Glucose is one of the fuels that our body uses for energy and its production is driven by a chemical called insulin. In diabetes, there may be a lack of insulin, or a lack of responsiveness to insulin meaning the glucose is unable to enter the cells. When the blood glucose levels are disrupted in this way, the nerves and tiny blood vessels that carry blood to different parts of the body become defective over time. The damage to the nerves causes both pain and numbness. The effects are usually worse in the feet and in severe cases ulcers may develop. Ulcers can lead to infection, amputation and even death. Wearing orthotics help reduce the chance of ulcer development by reducing pressure on the foot, with memory foam orthotic being the most suitable for this purpose.
