Introduction
When the body is invaded by bacteria, the immune system activates its defense mechanisms, which may lead to an increase in white blood cells and neutrophils, resulting in elevated levels of both in a routine blood test. This condition is usually accompanied by symptoms such as fever and cough. It is recommended to treat under medical supervision with medications such as amoxicillin capsules, clarithromycin capsules, and metronidazole tablets.
Under normal circumstances, elevated levels of white blood cells and neutrophils in a complete blood count (CBC) may be caused by intense physical exercise, drug reactions, bacterial infections, viral infections, or systemic lupus erythematosus. If discomfort occurs, it is recommended to seek medical attention promptly. The specific analysis is as follows:
1. Intense Physical Exercise
After intense physical activity, the body enters a state of stress, causing white blood cells and neutrophils stored in the bone marrow to be released into the bloodstream. This leads to elevated levels of white blood cells and neutrophils in the CBC. This phenomenon is a normal physiological response that does not require special treatment and typically returns to normal after rest.
2. Drug Reaction
Long-term use of medications such as corticosteroids or non-steroidal anti-inflammatory drugs (NSAIDs) may affect the bone marrow's production or release of white blood cells and neutrophils into the bloodstream, resulting in elevated levels in the CBC. It is recommended to discontinue or adjust these medications under a doctor’s guidance, and if necessary, switch to alternative treatment options.
3. Bacterial Infection
When the body is invaded by bacteria, the immune system activates its defense mechanisms, which may lead to an increase in white blood cells and neutrophils, resulting in elevated levels in the CBC. This condition is often accompanied by symptoms such as fever and cough. It is recommended to treat under medical supervision with medications such as amoxicillin capsules, clarithromycin capsules, or metronidazole tablets.
4. Viral Infection
After the body is infected by a virus, an inflammatory response may be triggered, leading to increased levels of white blood cells and neutrophils in the CBC. Symptoms may include cough and sore throat. Under medical guidance, treatment may include antiviral medications such as oseltamivir phosphate capsules, antiviral oral solution, or acyclovir tablets.
5. Systemic Lupus Erythematosus
When the immune system mistakenly attacks the body's own tissues, it may trigger systemic lupus erythematosus, causing an inflammatory response that can result in elevated white blood cell and neutrophil counts in the CBC. This condition is often accompanied by symptoms such as rashes and photosensitivity. Treatment under medical supervision may include medications such as betamethasone tablets, prednisolone acetate tablets, or hydrocortisone tablets.
In daily life, appropriate physical exercise can be increased to enhance physical strength and boost the body's immunity.
