The first urine in the morning is tea-colored, there may be the following reasons: First, there is a concentration of urine, such as when drinking too little water at night, sweating more, or when there is fever and high 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, urinary urgency, painful urination, and after proper rehydration, the urine color can return to normal color, and this situation does not require any medication; secondly, if there are bleeding disorders in the urinary tract, such as positive occult blood in the urine, infection, etc., then the urine is stored in the bladder, and after the red blood cells are sulfated, it will produce a tea-colored change. When urine is stored in the bladder for more than four hours, the discharged urine can be teal in color, and a urinalysis test is needed to find out if there is a positive result of occult blood. Elevated blood bilirubin levels may be seen when liver function tests are performed.
