Does Diabetes Cause Hair Loss?

Your body is unable to produce insulin if you have diabetes or doesn’t use it well, or both. A hormone named ‘insulin’ moves sugar from foods you consume from your bloodstream into the cells to be used or stored as energy.

If you don’t have insulin or not used well, sugar may build up in bloodstreams. Excess sugar may damage organs around the body, such as your nerves, eyes, and kidneys. It may also cause damage to the blood vessels. These vessels are known to carry a lot of oxygen in the body to nourish your tissues and organs. Damaged blood vessels are often unable to produce enough oxygen to support hair follicles. So, hair growth cycle is also affected due to lack of oxygen.
