Introduction
In general, elevated white blood cells in urine may be related to factors such as intense physical activity, cold stimulation, dehydration, urinary tract infections, or kidney stones. If discomfort occurs, it is recommended to seek medical attention promptly and receive appropriate treatments—such as general management or medication—under a doctor's guidance. In daily life, it is important to maintain adequate fluid intake, follow a healthy diet, and avoid strenuous exercise.
Under normal circumstances, elevated white blood cells in urine may be related to factors such as intense exercise, cold stimulation, dehydration, urinary tract infections, or kidney stones. If discomfort occurs, it is recommended to seek medical attention promptly. The specific analysis is as follows:
1. Intense Exercise
After vigorous physical activities such as running, basketball, or volleyball, the body's circulation accelerates, which may allow some white blood cells to enter the urine via the bloodstream, resulting in elevated white blood cell levels in the urine. No special treatment is required; adequate rest and hydration are sufficient.
2. Cold Stimulation
When temperatures drop or clothing is insufficient for warmth, the body increases white blood cell production to resist the cold. Some of these white blood cells may be excreted in the urine, leading to higher levels in the urine. It is important to stay warm, dress appropriately, and avoid prolonged exposure to cold environments.
3. Dehydration
In hot weather, increased sweating combined with inadequate fluid intake can lead to dehydration. As body fluids decrease, urine becomes more concentrated, potentially increasing the concentration of white blood cells in the urine. Timely rehydration with water or electrolyte drinks is necessary to restore normal hydration levels.
4. Urinary Tract Infection (UTI)
Infrequent urination may allow bacteria to grow and multiply in the urethra, leading to a urinary tract infection. These bacteria can trigger an inflammatory response, causing local accumulation of white blood cells, which may then appear in the urine, resulting in elevated white blood cell counts. Treatment should follow medical advice and may include medications such as levofloxacin hydrochloride tablets, compound sulfamethoxazole tablets, or cefradine capsules.
5. Kidney Stones
Long-term excessive intake of salty, high-protein, or high-calcium foods increases the risk of kidney stone formation. Movement or impaction of kidney stones may cause inflammation, attracting white blood cell accumulation and leading to elevated white blood cells in the urine. Under medical guidance, medications such as Pishikeli (Lithotripsy Granules), Shenshitong Granules, or Compound Lysimachiae Herba Granules may be used for treatment.
In daily life, it is important to maintain adequate fluid intake, follow a healthy diet, and avoid excessive physical exertion.
