Several conditions can lead to elevated urea levels in children:
1. Dehydration: Insufficient fluid intake can concentrate urea in the blood. 2. Kidney Disease: Conditions like glomerulonephritis or chronic kidney disease can impair the kidneys' ability to filter urea. 3. High Protein Diet: Excessive protein intake can increase urea production. 4. Medications: Certain drugs, such as corticosteroids, can elevate urea levels.
