Diabetes develops when the body cannot effectively process glucose (sugar) from food, leading to higher-than-normal blood sugar levels. In people without diabetes, insulin -- a hormone made by the body -- moves glucose from the bloodstream into cells to be used as energy. In people with diabetes, that process is disrupted, either because the body makes too little insulin or cannot use it effectively.
Left unmanaged over time, elevated blood sugar can affect the heart, nerves, circulation, eyes, and kidneys. The good news: with consistent monitoring, education, and everyday habits, diabetes is very manageable, and most patients go on to live full, active lives.
