Causes, Diagnosis & Treatment of Dark Urine | CMC Hospital

Dark urine, often described as a deeper color than usual, can be indicative of various underlying causes and related conditions:

  1. Dehydration: Insufficient fluid intake can lead to concentrated urine, resulting in a darker color.
  2. Hematuria: The presence of blood in the urine can cause it to appear dark or reddish, and it can be due to conditions like urinary tract infections, kidney stones, or bladder cancer.
  3. Medications: Certain drugs, such as antibiotics, laxatives, or medications for malaria or muscle injuries, can cause dark urine as a side effect.
  4. Liver Conditions: Liver disorders like hepatitis, cirrhosis, or liver tumors can lead to bilirubin buildup, causing dark urine. This may also be accompanied by yellowing of the skin and eyes (jaundice).
  5. Hemolysis: Breakdown of red blood cells can release hemoglobin into the bloodstream, leading to dark-colored urine. Conditions like hemolytic anemia can cause this.
  6. Rhabdomyolysis: Muscle injury or breakdown (as seen in severe trauma or muscle diseases) can result in the release of myoglobin into the urine, causing it to appear dark.
  7. Bile Duct Obstruction: Blockage of the bile ducts due to gallstones, tumors, or other issues can lead to dark urine along with pale stools and jaundice.
  8. Porphyria: A group of rare genetic disorders that affect the production of heme (a component of hemoglobin) can lead to dark urine during acute attacks.
