7. Brown or Cola-Colored
What It Means: Possible severe dehydration, liver issues, or muscle injury.
Explanation: Brown urine can occur in cases of severe dehydration but also in situations where muscle damage has released myoglobin, a protein, into the bloodstream. This condition, known as rhabdomyolysis, places heavy stress on the kidneys. Brown urine may also be a sign of liver disease or bile duct blockages.
Caution: Brown or cola-colored urine warrants immediate attention, especially if accompanied by muscle pain, weakness, jaundice, or swelling. Rhabdomyolysis can cause kidney damage if untreated, and liver or bile duct conditions need prompt medical intervention.
8. Blue or Green
What It Means: Possible infections, medication effects, or genetic disorders.
Explanation: Blue or green urine is rare but can occur due to certain medications, dyes used in medical tests, or bacterial infections like Pseudomonas that cause green urine. A rare genetic condition called familial hypercalcemia (or “blue diaper syndrome”) can also cause blue-tinged urine.
Caution: If you notice blue or green urine without an obvious dietary or medication-related cause, seek medical advice. Although rare, infections or genetic conditions could be the underlying cause.
9. Cloudy or Murky
What It Means: Possible urinary tract infection (UTI), kidney stones, or dehydration.
Explanation: Cloudy urine often indicates an infection, particularly UTIs, where bacteria or white blood cells can cause a cloudy appearance. High levels of certain minerals or crystals in the urine, which can lead to kidney stones, can also cause cloudiness.
Caution: Cloudy urine accompanied by a foul odor, burning sensation, pain, or frequent urge to urinate is often a sign of a UTI, which should be treated promptly to prevent infection from reaching the kidneys.
