A man's urine is red and there is no other feeling

Male urine that is red in color but without other discomfort may be a symptom of hematuria, which is usually related to factors such as diet, drugs, urinary system inflammation, or stones. It is recommended to seek medical examination promptly to determine the cause of the disease.

After eating foods rich in natural pigments such as red dragon fruit and beets, temporary red urine may occur. The color will return to normal after stopping eating. Some drugs, such as rifampicin capsules, phenolphthalein tablets, and nitroimidazole antibiotics, may also cause the urine to turn red, and the symptoms will disappear after stopping the drug. Urinary system infections such as cystitis and urethritis may cause painless hematuria, usually accompanied by frequent urination and urgency, but some patients only show a change in urine color. Urinary system stones such as kidney stones and ureteral stones may scratch the mucosa and cause bleeding during movement. However, if the stones are small or fixed in position, only hematuria may occur without obvious pain. Prostatic hyperplasia or tumor may only present as painless hematuria in the early stage, and further investigation through urinary system ultrasound or cystoscopy is required.

It is recommended to avoid strenuous exercise and drink more than 2000 ml of water daily to dilute urine. Observe changes in urine color and record accompanying symptoms such as difficulty urinating, waist and abdominal pain, etc. Avoid consuming alcohol and spicy food that may irritate the urinary system. If hematuria lasts for more than 24 hours or symptoms such as fever and low back pain occur, you must immediately seek medical attention from a urology department and complete routine urinalysis, urinary tract ultrasound and other examinations. Middle-aged and elderly men should undergo prostate-specific antigen screening regularly to rule out the possibility of malignant lesions.
