Diabetes is defined as?

• A. A disease of the bones
• B. Disease where body is unable to produce enough insulin
• C. A viral infection of the mouth
• D. A neurological condition

Answer: (B)

Diabetes is a chronic metabolic condition in which the body cannot regulate blood sugar properly due to problems with insulin. In many cases this means the body is unable to produce enough insulin, so glucose remains in the bloodstream instead of entering cells to be used for energy. This idea captures the main mechanism behind diabetes, especially type 1, where lack of insulin production is central. The other options describe conditions that involve bones, viral infections of the mouth, or neurological issues, which are not what diabetes is. Understanding this helps in practice because blood sugar control affects healing and infection risk in dental care.
