What Causes Frequent Urination in Men?
Generally, increased urinary frequency in men may result from excessive fluid intake, psychological stress, urethritis, prostatitis, or overactive bladder syndrome. If associated discomfort symptoms occur, it is advisable to seek timely evaluation and treatment at a reputable hospital. A detailed analysis follows:

1. Excessive Fluid Intake
Consuming more fluids than required increases renal water metabolism, thereby elevating both urine volume and frequency of urination. Moderately reducing daily fluid intake—while maintaining regular, spaced hydration—and avoiding large volumes of water consumed at once may help alleviate this issue.
2. Psychological Stress
Heightened emotional tension stimulates the nervous system, triggering frequent contractions of the detrusor muscle in the bladder, leading to urinary frequency and increased urine output. Stress reduction techniques such as deep breathing exercises and walking can help stabilize mood and minimize emotional fluctuations.
3. Urethritis
Bacterial infection of the urethra causes inflammation, resulting in mucosal hyperemia and heightened sensitivity; even minor stimuli may provoke urgent urination, increasing voiding frequency. Treatment may include antibiotics prescribed by a physician—such as levofloxacin tablets, amoxicillin capsules, or norfloxacin capsules—along with diligent personal hygiene practices.
4. Prostatitis
Inflammation and swelling of the prostate gland exert pressure on and irritate the bladder neck, shortening the interval between urinations and causing increased urinary frequency and volume. Medications prescribed by a physician—including tamsulosin extended-release capsules, Pule’an tablets (a traditional Chinese medicine formulation), and saw palmetto extract capsules—may be used. Additionally, avoid prolonged sitting and urinary retention, and maintain a light, balanced diet.
5. Overactive Bladder Syndrome
Excessive, uncoordinated detrusor muscle activity leads to involuntary bladder contractions, resulting in frequent urination and increased urine output. Pharmacotherapy under medical supervision may include mirabegron extended-release tablets, solifenacin tablets, or tolterodine tablets. In severe cases, surgical intervention—such as detrusor myectomy—may be considered.
In daily life, maintain consistent and moderate fluid intake and emotional stability; practice good perineal hygiene; avoid prolonged sitting and urinary retention; and promptly undergo diagnostic evaluation and targeted treatment if persistent urinary frequency or polyuria develops.
