The first urine in the morning is tea-colored, there may be the following reasons: First, there is a concentration of urine, such as too little water at night, more sweating, or when there is fever, higher evaporation of body temperature, there can be a change of urine color to strong tea color, or to tea color. Generally, it is not accompanied by frequent urination, urgent urination, painful urination, and after proper rehydration, the urine color can return to normal color, and this situation does not require any medication. Second, if there are bleeding diseases in the urinary tract, such as positive occult blood in the urine and infection, the urine is stored in the bladder, and the red blood cells will produce a teal color change after being sulfated. When urine is stored in the bladder for more than four hours, the urine that is discharged can be teal in color, and a urinalysis test is needed to find out if there is a positive result for occult blood. Third, if the urine contains more bilirubin and urobilinogen, the urine can appear brown or tea-colored, mostly due to hepatocellular jaundice or obstructive jaundice, and elevated blood bilirubin levels can be seen when liver function tests are performed.
