What causes high white blood cells in urine test?

Elevated white blood cells in urine test results may be caused by insufficient water intake, intense physical exercise, urethritis, nephritis, cystitis, and other factors. It is recommended to seek medical attention promptly, identify the underlying cause, and receive symptomatic treatment under a doctor's guidance. Specific analyses are as follows:

1. Insufficient water intake: Not drinking enough water over a prolonged period or inadequate fluid intake may lead to concentrated urine, which appears dark yellow. This can also result in a mild increase in white blood cell count. Increasing daily water intake and maintaining sufficient hydration can help alleviate elevated white blood cells in urine tests.

2. Intense physical exercise: Prolonged high-intensity exercise can place the body in a state of stress, potentially causing muscle soreness and temporary elevation of white blood cells. It is recommended to ensure adequate rest, appropriately replenish fluids, and reduce exercise intensity to help relieve these symptoms.

3. Urethritis: This may be related to poor personal hygiene or pathogen infection. When pathogens invade the urethra, the body may mount an immune response, leading to increased white blood cells in urine and possibly accompanied by frequent urination. Patients are advised to follow medical instructions and use medications such as cefixime capsules, minocycline hydrochloride capsules, or roxithromycin capsules for treatment.

4. Nephritis: Abnormal kidney function and inflammation may result from conditions such as kidney stones or low immunity, potentially leading to urinary tract infections. When urinary tract infection occurs, bacteria may irritate the urinary tract tissues, increasing white blood cells. Patients may also experience symptoms such as back pain and fatigue. It is recommended to follow medical advice and use medications such as dexamethasone tablets, Yishen Huashi granules, or Nephritis Recovery Tablets for treatment.

5. Cystitis: This condition may be caused by bladder lesions or bacterial infections. When the bladder is infected by bacteria, the body's immune system responds by releasing white blood cells, which often leads to elevated white blood cell counts in urine tests. Patients may also experience symptoms such as hematuria (blood in urine) and abnormal urination. It is recommended that patients follow medical instructions and use medications such as ampicillin capsules, cefadroxil granules, or amoxicillin tablets as part of treatment.

In daily life, patients should maintain good genital hygiene, wash and change underwear regularly, and ensure adequate daily water intake to help keep the urinary tract clear and prevent urinary tract infections. Additionally, avoiding excessive fatigue and ensuring quality and sufficient sleep can enhance the body's resistance and support recovery from illness.
