What Is Diabetes Mellitus

Diabetes mellitus is a disorder which can occur either due to a lack of an important hormone “Insulin” or resistance to its effects. As a result the body is unable to properly metabolize carbohydrates (e.g., food starches, sugars, cellulose) and an excessive amount of sugar accumulates in the blood (hyperglycemia).

It is interesting to note that normally sugar does not appear in urine but in diabetes it may appear in urine if the glucose level in blood rises above 180 mg/dl.
