What is diabetes mellitus?

What is diabetes mellitus?

• A. A condition of excess sugar in the bloodstream
• B. A chronic disease of insulin deficiency or resistance
• C. A viral disease affecting the liver
• D. An inflammation of the gallbladder

Answer: (B)

Diabetes mellitus is a chronic disease characterized by either a lack of insulin production or the body's inability to use insulin effectively. Option A is incorrect because although excess sugar in the bloodstream is a symptom of diabetes, it does not fully encompass the condition. Option C is incorrect because diabetes is not a viral disease and it does not affect the liver. Option D is incorrect because it refers to a completely different condition and does not relate to diabetes.
