Dark urine despite drinking water

A few drinks may not replace fluid lost through sweating, fever, vomiting, diarrhoea, or frequent urination. Urine is also naturally more concentrated after sleep. Colour can change because of vitamins, medicines, foods, menstrual blood, or a sample that has mixed with other fluid. Persistent brown or tea-coloured urine deserves attention, particularly with yellow eyes or skin, pale stools, nausea, itching, or unusual tiredness. Burning, urgency, pelvic discomfort, fever, or side pain shifts concern toward a urinary cause. The colour alone cannot identify which explanation applies.

Record when the darker urine appears, how much you are passing, and whether it changes later in the day. Review new medicines and supplements with a pharmacist, and do not stop prescribed treatment on your own. Replace ongoing fluid losses with regular drinks if you have no fluid restriction. If the change persists despite usual intake, book an appointment; urine testing and blood tests may clarify the source.

Seek urgent care for very little urine, inability to keep fluids down, fainting, confusion, severe pain, fever with chills, visible blood, or yellowing of the skin or eyes. Arrange earlier review if you are pregnant, have kidney or liver disease, or the colour is steadily becoming darker.

Ask whether your fluid intake matches your losses, whether a medicine could alter urine colour, and which urine or blood tests would distinguish concentration from blood, infection, or liver-related changes.
