Red, pink, and brown: the colors that should not be ignored
Pink or red urine is startling but not always a medical emergency. Beets, blackberries, and rhubarb are well-known dietary causes. However, the same colors can signal blood in the urine, which may be associated with urinary tract infections, kidney stones, kidney disease, bladder conditions, or other urinary tract disorders.
If the color cannot be explained by something recently eaten or taken, prompt medical evaluation is important.
Brown urine may result from severe dehydration, certain medications, specific foods, liver disorders, or kidney disease. In rare cases, intense exercise can trigger muscle breakdown that produces brown discoloration. If it continues or is accompanied by other symptoms, medical assessment is recommended.
Blue or green urine is uncommon and is most often linked to medications, dyes used during diagnostic procedures, or artificial food coloring. Less commonly, it may be associated with specific infections or rare metabolic disorders. If the change cannot be explained and persists, a healthcare provider should be consulted.
Five symptoms that turn a color change into a reason to call a doctor
Many urine color changes resolve on their own with better hydration or once a food or medication clears the system. But certain accompanying symptoms elevate the situation and require medical advice without delay.
Those symptoms include: pain or burning during urination, visible blood, fever, persistent abdominal, side, or back pain, and yellowing of the skin or eyes. Urine that remains unusually dark or discolored despite adequate fluid intake also falls into this category.
