Step 1: Concept
Diabetes mellitus is characterized by high blood glucose levels (hyperglycemia) due to insulin issues.
Step 2: Meaning
When blood sugar is very high, the kidneys cannot reabsorb all the glucose, leading to its presence in urine (glycosuria).
Step 3: Analysis
In severe cases, the body starts breaking down fats for energy, producing ketones which are also excreted in urine (ketonuria). While hyperglycemia is the cause, glycosuria and ketonuria are the specific diagnostic clinical findings in urine.
Step 4: Conclusion
Hence, the patient will have ketonuria and glycosuria.
