My husband's urine is dark orange: what should we know?

Urine can become darker when the body has less fluid available, especially after sweating, vomiting, diarrhoea, fever, or limited drinking. Strongly coloured foods, vitamins, and some medicines can also change its appearance. Liver or bile-flow problems may make urine tea-coloured or brownish and can occur with yellowing of the eyes or skin, pale stools, itching, nausea, or discomfort under the right ribs. Blood, muscle breakdown, or a urinary infection are other possibilities that need clinical review. The colour alone cannot identify the cause.

Note when the colour started, how much he is drinking, and whether it changes after ordinary fluids. If he has been losing fluid and can drink safely, offer regular water and monitor the next few urinations. Do not stop a prescribed medicine without advice; record all medicines, supplements, and recent foods for the clinician. Arrange an appointment if the colour persists, returns, or comes with pain, burning, fever, reduced urine, or unusual tiredness. A clinician may examine him and test urine and blood.

Seek urgent medical help for very little or no urine, confusion, fainting, severe weakness, severe abdominal or back pain, repeated vomiting, or yellow skin with worsening illness. Get prompt assessment for red or cola-coloured urine, fever with urinary symptoms, or dark urine after intense exertion. These signs can indicate significant dehydration, bleeding, infection, or organ stress and should not be assessed by colour alone.

When did the colour change, and could dehydration, a new medicine, supplement, or food explain it? Does he need urine, liver, kidney, or blood testing? Which symptoms should prompt same-day care?
