What causes white-colored urine?

Under normal circumstances, urine is colorless or pale yellow. However, some individuals may notice their urine appearing white. White-colored urine generally indicates an underlying health abnormality. If the cause remains undiagnosed and untreated promptly, the condition may worsen and pose serious risks to overall health. So, what causes white urine? Below, we address this question.

What Causes White Urine?

1. Prostatitis

White, viscous fluid may appear at the beginning or end of urination—typically prostatic secretions. Patients may experience urinary frequency, urgency, dysuria, as well as perineal fullness or lower abdominal discomfort.

2. Urinary Tract Infection (UTI)

Conditions such as pyelonephritis, urethritis, or cystitis may result in cloudy, white-tinged urine. White, flocculent sediment may be visible in the urine, accompanied by urinary frequency, urgency, and other lower urinary tract irritative symptoms. Diagnosis requires urinalysis and urine culture.

3. Crystalluria (Salt-Induced Urine Turbidity)

This occurs when solute concentrations in urine rise, leading to supersaturation and crystallization—such as urate, phosphate, or oxalate crystals. Typically, no urinary irritative symptoms are present.

4. Chyluria

Chyluria results from lymphatic fluid entering the urinary tract—often triggered by consumption of fatty or rich foods—causing urine to appear milky white. Patients should undergo chyluria testing at a hospital; once confirmed, cystoscopy is recommended, followed by targeted treatment.

The above outlines the potential causes of white urine. We hope this information is helpful to you.
