What should you know about dark color urine in the morning?

Urine can look deeper yellow when you have not taken fluids overnight. A strong smell, dry mouth, thirst, dizziness or passing urine less often can support dehydration. Food, supplements and medicines may also alter urine color. Brown or tea-colored urine, especially with yellowing of the skin or eyes, nausea, pale stools or unusual tiredness, can point to a liver problem and should not be dismissed. Heat exposure and heavy sweating can increase fluid loss; learn more about Dehydration and Heat Exhaustion.

Notice the shade in the next few bathroom visits and whether it becomes lighter after drinking fluids. Sip water regularly, particularly after exercise or time outdoors, unless a clinician has told you to restrict fluids. Review any new vitamins or medicines with a pharmacist rather than stopping prescribed treatment yourself. Record associated pain, fever, burning, frequency, vomiting or changes in bowel movements. The Dark Urine guide can help you describe the change clearly.

Arrange medical advice if the dark color continues despite normal fluid intake, keeps returning, or occurs with burning, pelvic pain, fever, side pain or blood. Seek urgent help for confusion, fainting, inability to keep fluids down, severe weakness, very little urine, intense abdominal pain, or yellow skin or eyes. Dark urine with marked heat-related symptoms needs prompt assessment.

Could dehydration, a medicine, supplement, liver condition or urinary problem explain this color? Which urine or blood tests would clarify the cause? How much fluid is suitable for me, and which warning signs should prompt urgent care?
