Urine bilirubin +1 indicates a positive bilirubin measurement inside the urine, which may be related to hepatocyte damage, biliary system disease, and hemolytic jaundice. Common causes and treatments 1. Damaged liver cells: If liver cells are damaged, then the uptake, binding and excretion functions of bilirubin may be impaired, which may lead to elevated urinary bilirubin. At the same time, the ability of hepatocytes to take up unconjugated bilirubin in plasma is reduced, which can lead to elevated bilirubin. It is mostly seen in acute viral hepatitis, which requires hospitalization; 2. Biliary system diseases: such as cholelithiasis, bile duct cancer, pancreatic head cancer, primary biliary cirrhosis, etc. Elevated bilirubin in urine is also seen in biliary obstruction, where bile stasis can raise bilirubin in the body, resulting in positive bilirubin in urine. Later in the disease, patients may experience jaundice, yellow skin, yellow urine, and even itchy skin. The cause should be promptly identified and then surgically treated to unblock the bile ducts; 3. Hemolytic jaundice: such as various hemolytic diseases, large burns, urinary bilirubin is metabolically produced after the destruction of red blood cells, to remove the cause, hormone therapy, plasma replacement, etc. can be given. Note: Increased urinary bilirubin needs to be taken seriously, need to improve blood routine, urine routine, liver function, kidney function examination, to clarify the cause, and give timely symptomatic treatment.
