Tea-coloured urine

Urine is usually pale yellow. Tea-coloured urine refers to urine that appears dark brown, resembling strong tea. This change in colour can occur for several reasons, ranging from dehydration to medical conditions.

Tea-coloured urine can occur because substances in the urine alter its colour. These include blood-related pigments such as haemoglobin (from red blood cell breakdown) and myoglobin (from muscle injury). Tea-coloured urine can also be seen with some urinary tract infections and with some medications. Liver and bile duct problems may cause dark urine when bilirubin is excreted into the urine.
