Introduction
Under normal circumstances, occult blood in urine refers to an increased number of red blood cells in a routine urinalysis, indicating the possible presence of red blood cells in the urine and suggesting potential bleeding. Occult blood in urine may be caused by intense physical exercise, urine contamination, ureteral stones, cystitis, colitis, or other conditions. Treatment may include general measures and medications under the guidance of a physician. If any discomfort occurs, it is recommended to seek medical attention promptly.
Under normal circumstances, occult blood in urine may be caused by intense physical exercise, urine contamination, ureteral stones, urethritis, cystitis, or other reasons. If discomfort occurs, it is recommended to seek medical attention promptly. Specific analyses are as follows:
1. Intense Exercise
After prolonged high-intensity exercise, due to the body's systems being in a highly stressed state, the kidneys may temporarily release red blood cells into the urine, resulting in occult blood. It is advisable to avoid strenuous exercise and ensure adequate rest.
2. Medication Effects
Certain medications, such as anticoagulants or analgesic-antipyretics, may affect kidney function or cause bleeding in the urinary system, leading to occult blood in urine. It is recommended to follow a doctor’s advice to adjust or discontinue medication as needed.
3. Urethritis
Bacterial infection is the primary cause of urethritis. Inflammation of the urethra can lead to urinary tract infections and cause the aforementioned symptoms. This condition may also be accompanied by urgency and hematuria. It is recommended to follow medical guidance and use medications such as amoxicillin-clavulanate potassium tablets, cefixime capsules, or norfloxacin capsules for treatment.
4. Cystitis
Bacterial invasion of the urinary tract can cause cystitis, leading to local vascular congestion, edema, or even rupture and bleeding, resulting in the above symptoms. It may also be accompanied by frequent urination and urgency. Treatment should follow medical advice using medications such as cefaclor dispersible tablets, amoxicillin-clavulanate potassium dispersible tablets, or gatifloxacin capsules.
5. Ureteral Stones
Urinary tract infections can promote the deposition of substances such as calcium phosphate apatite, forming ureteral stones. As stones move, they may scratch the urethral mucosa and cause bleeding, potentially leading to occult blood in urine. Symptoms may also include painful urination and fever. Treatment under a doctor’s guidance may include cefixime granules, lithotripsy granules, or jieshi tong capsules.
To prevent occult blood in urine, it is important to maintain personal hygiene, change clothes regularly, maintain regular sleep patterns, avoid irritating foods, and undergo routine medical check-ups at the hospital.
