Introduction
In general, elevated high-sensitivity CRP levels may be caused by factors such as intense physical exercise, late pregnancy, acute upper respiratory tract infection, rheumatoid arthritis, or acute cholecystitis. It is recommended to seek medical attention promptly, identify the underlying cause, and undergo symptomatic treatment under a doctor's guidance. Daily, maintain a light diet, reduce intake of spicy and greasy foods, and maintain regular sleep patterns while avoiding staying up late.
Generally, elevated high-sensitivity CRP (hs-CRP) levels may result from conditions such as after strenuous exercise, in late pregnancy, acute upper respiratory tract infection, rheumatoid arthritis, or acute cholecystitis. It is recommended to seek timely medical attention to identify the underlying cause and receive appropriate treatment under a doctor's guidance. Detailed explanations are as follows:
1. After strenuous exercise: During high-intensity physical activity, minor muscle damage may trigger a stress response, temporarily increasing hs-CRP levels. This is usually not accompanied by other discomforts. Adequate rest, hydration, and electrolyte replacement after exercise, along with avoiding strenuous activity in the short term, can help hs-CRP return to normal within 1–2 days.
2. Late pregnancy: In the later stages of pregnancy, women's bodies are in a state of physiological stress with active tissue metabolism, which may cause mild elevations in hs-CRP. This is considered a normal physiological change. Pregnant women should maintain regular作息, ensure sufficient sleep, consume adequate protein and vitamins, and attend regular prenatal checkups to monitor changes in health indicators.
3. Acute upper respiratory tract infection: Often caused by infection with Haemophilus influenzae or Streptococcus pneumoniae, inflammation can elevate hs-CRP levels and may be accompanied by sore throat and cough. Patients may use medications such as amoxicillin capsules, cefaclor dry suspension, or ambroxol hydrochloride oral solution as directed by a physician to control the infection.
4. Rheumatoid arthritis: Autoimmune abnormalities that activate inflammation can elevate hs-CRP levels and are often accompanied by joint swelling and pain. Patients should take medications such as methotrexate tablets, leflunomide tablets, or diclofenac sodium sustained-release tablets as directed by a physician to alleviate symptoms.
5. Acute cholecystitis: Inflammation caused by gallbladder duct obstruction and bacterial infection can significantly elevate hs-CRP levels and is often accompanied by right upper abdominal pain. Patients may receive treatment with medications such as ceftriaxone sodium injection, ursodeoxycholic acid capsules, or racemic scopolamine butylbromide tablets as directed by a physician.
In daily life, maintaining a bland diet, reducing intake of spicy and greasy foods, and avoiding late nights are important. Engaging in moderate physical activities such as brisk walking or yoga can enhance immunity. Monitoring bodily symptoms and maintaining health are also essential.
