Why does urine suddenly turn yellow?

Sudden yellowing of urine may be caused by prostate inflammation and urinary tract infection, or may be an early manifestation of glomerulonephritis and nephrotic syndrome. Further examination is needed, including urine routine, urine culture, prostatic fluid routine, urinary system B-ultrasound examination, 24-hour endogenous creatinine clearance rate, urine osmolality and urine microprotein. If it is caused by urinary tract infection or prostatitis, you can choose some anti-inflammatory drugs, such as Sanjin Tablets, Relinqing Capsules, Bazheng Capsules for 4-8 weeks. After controlling inflammation, urine will turn clear. If it is clear that glomerulonephritis or nephrotic syndrome exists after examination, you should choose Jinshuibao Capsules or Bailing Capsules for at least 2-3 months. The color of urine will become clear.
