Dark yellow urine with a strong odor may be caused by various factors, including both physiological and pathological reasons:

1. Physiological factors mainly include insufficient water intake, dietary influences, or prolonged urine retention leading to urine concentration, which deepens the urine color and intensifies its odor.

2. Pathological factors may involve diseases such as urinary tract infections, cystitis, pyelonephritis, cirrhosis, and glomerulonephritis. These conditions can affect urine production and excretion, altering urine composition and resulting in abnormal color and smell.

It is recommended to maintain adequate hydration and monitor whether symptoms improve. If dark yellow urine with a strong odor persists, especially accompanied by other symptoms such as fever or back pain, prompt medical attention is advised.
