The frequent yellowing of urine is usually caused by drinking less water, holding urine for a long time, or eating fewer vegetables and fruits. This situation is a physiological cause, and does not constitute a major harm to the body. If you want to improve this situation, it is recommended that you can drink more water, eat more vegetables and fruits, and urinate regularly, which can improve the clinical symptoms of yellow urine. There is also a pathological cause, including urinary tract infection and liver and gallbladder disease, which may lead to yellow urine. When patients have this clinical symptom, they need to go to the hospital for relevant examination to clarify the diagnosis. It is recommended that they can go for urine routine, urine culture, liver, biliary, pancreatic and spleen ultrasound, and urinary tract ultrasound to clarify the diagnosis. Once the diagnosis of urinary tract infection is confirmed, it is recommended to take levofloxacin, ofloxacin and other drugs for conditioning treatment, which can improve the symptoms of yellow urine.
