What causes yellow urine in men?

Yellow urine in men may be caused by factors such as insufficient water intake, excessive sweating, urethritis, ureteral stones, or hepatitis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive appropriate treatment under the guidance of a qualified physician. Specific analysis is as follows:

1. Insufficient Water Intake

When men do not drink enough water, the body lacks sufficient fluid to maintain normal urine dilution, which may lead to concentrated urine and result in yellow-colored urine. It is recommended to increase daily water intake to ensure adequate hydration, helping to dilute urine and improve the symptom of yellow urine.

2. Excessive Sweating

During intense physical activity or in high-temperature environments, the body regulates temperature through sweating, which can lead to increased fluid loss. If fluids are not replenished promptly, urine may become concentrated, causing it to appear darker yellow. It is advisable to regularly rehydrate to maintain fluid balance and prevent excessive urine concentration.

3. Urethritis

This condition may be related to mechanical irritation or bacterial infection. When bacteria multiply in the urethra, they may irritate the urethral mucosa, leading to yellowish urine. Symptoms may also include frequent urination and painful urination. Patients are advised to follow medical instructions and take medications such as azithromycin granules, cefixime granules, or roxithromycin tablets for treatment.

4. Ureteral Stones

This may be associated with urinary tract infections or inadequate water intake. The condition may obstruct urine flow, causing urine to stagnate in the urinary tract, resulting in concentrated urine and yellow discoloration. Additional symptoms may include flank pain and hematuria (blood in urine). Patients should follow medical advice and use medications such as lithotripsy granules, urolithiasis-relieving pills, or stone-dissolving tablets as directed.

5. Hepatitis

Hepatitis is usually caused by heavy alcohol consumption, viral infections, or other factors. The disease may lead to abnormal bile secretion, allowing bilirubin from bile to enter the urine, thereby turning urine yellow. Other possible symptoms include jaundice (yellowing of the skin) and fatigue. Patients should use medications such as azathioprine tablets, bicyclol tablets, or recombinant human interferon α2b injection under a doctor's supervision to manage symptoms.

In daily life, patients are advised to maintain a light diet and consume fresh vegetables and fruits such as radishes, cabbage, and tomatoes. Avoiding late nights and maintaining a positive, optimistic mindset can also benefit recovery.
