What's wrong with dark brown urine?

The main reasons for dark brown urine are dietary factors, long-term urine retention, urinary tract infection, etc.

1. Dietary factors

If you consume too much red pitaya, purple potato and other foods recently, it may cause dark brown urine color, mainly because the pigment in the food cannot be completely absorbed by the human body and excreted with urine.

2. Long-term urine retention

If you hold urine for a long time, no urination, so that urine accumulates in the bladder for too long, it may cause urine color to deepen and become dark brown.

3. Urinary tract infection

When the urinary tract is infected by bacteria, viruses and other microorganisms, inflammation may occur, easily causing hematuria, resulting in dark brown urine.
