Which pathological condition is characterized by the presence of glucose in the urine?
Solution
Correct Answer: Option A
- The pathological condition characterized by the presence of glucose in the urine is known as Glycosuria.
- Normally, the kidneys reabsorb all the filtered glucose, so urine should contain no or very minimal glucose.
- However, when blood glucose levels exceed the renal threshold (approximately 180 mg/dL), the kidneys cannot reabsorb all the glucose, leading to its excretion in the urine.
- This condition is commonly seen in patients with uncontrolled diabetes mellitus.
To clarify the other options:
- Proteinuria refers to the presence of protein in the urine, often indicating kidney damage or disease.
- Hematuria is characterized by the presence of red blood cells or blood in the urine, which may suggest urinary tract infections, stones, or trauma.
- Ketonuria is the excretion of ketone bodies in the urine, typically associated with diabetic ketoacidosis or prolonged fasting.
Hence, the correct answer is Glycosuria because it directly refers to glucose in the urine.
