What causes high white blood cells in urine?
Under normal circumstances, elevated white blood cells in urine may be associated with factors such as intense physical exercise, prolonged exposure to cold, urinary tract infections, pyelonephritis, and interstitial nephritis. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:
1. Intense Physical Exercise
After engaging in strenuous activities such as running or playing sports, the body may experience a stress response that activates the immune system, leading to some white blood cells being excreted in the urine. This can temporarily result in increased white blood cells in the urine. It is important to reasonably schedule rest and recovery periods to ensure adequate rest and relaxation for the body.
2. Prolonged Exposure to Cold
When exposed to cold environments for extended periods, the body may activate its immune system to resist the cold, potentially causing a mild increase in white blood cells in the urine. Adequate warmth should be maintained, and prolonged exposure to cold environments should be avoided to prevent adverse health effects from chilling.
3. Urinary Tract Infection (UTI)
Urinary tract infections are primarily caused by holding urine or insufficient fluid intake. They may affect the urethra, bladder, or kidneys, triggering local inflammatory responses and prompting immune system activation, which may lead to a significant increase in urinary white blood cells. Symptoms may include frequent urination, urgency, and painful urination. Patients may follow medical advice to use medications such as norfloxacin capsules, amoxicillin capsules, or Niaoshining capsules for treatment.
4. Pyelonephritis
Pyelonephritis is mainly caused by bacterial infection, which may damage kidney tissue and mobilize large numbers of white blood cells to the infected area. Some of these white blood cells are then excreted in the urine, resulting in significantly elevated urinary white blood cell levels. Additional symptoms may include fever, chills, and flank pain. Treatment may be conducted under the guidance of a healthcare professional using medications such as mecloxacillin sodium for injection, amikacin sulfate injection, or Yinhua Miniyanling tablets.
5. Interstitial Nephritis
Interstitial nephritis may be triggered by factors such as drug allergies or autoimmune diseases. These factors can damage the renal interstitial tissue,引发 an inflammatory response and elevate white blood cell count in the urine. Other possible symptoms include reduced urine output, edema, and high blood pressure. Patients may follow medical instructions to use medications such as prednisolone tablets, compound cyclophosphamide tablets, or irbesartan hydrochlorothiazide tablets for treatment.
Maintaining healthy lifestyle habits is essential—balancing exercise and rest, keeping warm, avoiding holding urine, and drinking sufficient water—to support overall health.
