What is the metabolic abnormality that underlies the characteristic symptoms of diabetes mellitus?

The metabolic abnormality that is responsible for diabetes mellitus is THE INABILITY OF THE BODY CELLS TO ABSORB ENOUGH GLUCOSE FROM THE BLOOD.

Explanation:

Diabetes mellitus is a metabolic disease condition in which the glucose molecules that are present in the blood are unable to enter the body cells. This may happen as a result of lack of insulin hormone or inability of insulin hormone to carry out its functions. People with diabetes mellitus usually have high amount of glucose in their blood because of the inability of the glucose molecules to enter the body cells. Because the glucose molecules can not enter the body cells for energy utilization, diabetic patients usually feel weak, thirsty and hungry and the excess sugar in their blood usually come out with urine when they urinate.

Diabetes treatment usually involve the use of artificial insulin to lower the raised glucose levels.
