Why is urine particularly yellow and concentrated?

The yellow and thick urine of the patient is mostly caused by the following reasons: 1, physiological factors, if the amount of drinking water in daily life is too small, it will cause urine concentration, so that the urine is yellow. 2, eating food with yellow pigment in life will also deepen the urine color. 3. Pathological factors cause urinary tract infection, which is one of the causes of yellow urine and especially pus. It is mostly due to fungal, bacterial, mycoplasma, chlamydia and other microbial infections. Under the stimulation of inflammation, yellow urine, pus, even frequent urination, urgency and other uncomfortable manifestations are caused. 4. The level of bilirubin in the body is too high, causing metabolites of bilirubin to accumulate in the urine, making the urine color darker. It is recommended to seek medical attention in time to prevent delay of illness. Drinking more water and urinating more in life can effectively improve the symptoms of deepening urine.
