Drinking tea in moderation does not generally cause yellowing of the urine, but it is possible that if large amounts of tea are consumed it may turn the urine yellow.
Drinking tea in moderation generally does not have adverse effects on the human body. However, tea contains tea pigments, such as beta-carotene, flavonols, etc. Drinking large amounts of tea may lead to pigmentation into the urine, making the urine yellow. It should be noted that the normal color of human urine would have been transparent or yellowish, if the urine is found to be yellowish, generally normal.
Drinking too little water leads to urine concentration, as well as diseases such as urinary tract infections, glomerulonephritis, dehydration and many other reasons may also cause yellow urine color. When the color of urine continues to be abnormal, it is recommended that the patient go to a regular hospital in time to have a relevant examination and then be treated by a professional doctor.
