What causes high white blood cell and platelet counts?

Generally, elevated white blood cells and platelets may be caused by intense physical activity, cold exposure, urethritis, cystitis, or glomerulonephritis. It is recommended to seek medical attention promptly to identify the underlying cause and receive appropriate treatment. Specific analyses are as follows:

1. Intense Physical Activity

Engaging in strenuous exercises such as sprinting or weightlifting may accelerate the body's metabolism, leading to the aforementioned symptoms. This may also be accompanied by muscle soreness, fatigue, and other discomforts. It is advisable to rest appropriately and drink water to rehydrate.

2. Cold Exposure

Being in a cold environment or weather may lead to a physiological increase in white blood cells and can affect circulation, indirectly causing an elevation in platelets. Symptoms such as chills and shivering may also occur. It is recommended to keep the body warm and avoid prolonged exposure to cold conditions.

3. Urethritis

This may be caused by bacterial infection. Inflammatory stimulation can trigger increased production of white blood cells. Platelet production and release may also rise, resulting in the above conditions. Symptoms such as frequent urination and painful urination may accompany this condition. Treatment under a doctor's guidance may include medications such as levofloxacin hydrochloride capsules, metronidazole tablets, or norfloxacin capsules.

4. Cystitis

Typically caused by bacterial infection of the bladder, inflammation may lead to elevated white blood cells and platelets. Symptoms such as urgency and pain during urination may also occur. Under medical supervision, treatments may include amoxicillin granules, erythromycin tablets, or cefixime capsules.

5. Glomerulonephritis

Usually caused by immune system abnormalities, this condition may impair kidney filtration function, leading to the aforementioned findings. Other symptoms may include hematuria (blood in urine) and proteinuria (protein in urine). Under a doctor’s guidance, medications such as triamterene tablets, tripterygium glycosides tablets, or Huangkui capsules may be used for treatment.

Maintaining healthy daily habits is important. Go to bed early and wake up early, aiming to sleep before 11 p.m. each night, avoiding staying up late, and ensuring sufficient sleep. Diet should be light and easy to digest. Consuming nutrient-rich foods such as lean meat, fish, eggs, milk, and carrots can help improve immunity.
