Why Is My Urine Brown?

The normal color of urine is light yellow, without turbidity or sediment, and it has no odor when just excreted. If brown urine appears, it must be taken seriously. Yellowish brown urine may be caused by bilirubinuria or urobilinogenuria. Bilirubinuria is often caused by inflammation, tumor, or stone blockage in intrahepatic or extrahepatic bile ducts, leading to bilirubin sodium entering the blood. When the bilirubin sodium in the blood exceeds a certain amount, bilirubinuria occurs. Urobilinogenuria is often caused by liver damage, resulting in increased intestinal absorption of urobilinogen, which enters the urine and causes urobilinogenuria. Sometimes in patients with hemolytic anemia, a large number of erythrocytes are destroyed, causing a large amount of urobilinogen to be absorbed into the portal vein circulation through the intestinal wall. Since the liver cannot convert excessive urobilinogen into bilirubin, urobilinogenuria occurs. Urine color classification table: Clear and colorless: Too much water intake, frequent urination. Transparent yellow: Normal body and good health. Dark yellow: Severe lack of water intake, pay attention to water intake. Amber/honey color: Slightly insufficient water intake. Dark brown: Liver problems, severe dehydration, or possibly spleen and kidney issues. Pink/red: Unless just eaten foods like blueberries or beetroot, it may be a sign of kidney or prostate problems, or symptoms of hematuria. Orange: Unless affected by dark-colored food, it may be a problem with the liver or bile ducts.
