Introduction
Acute inflammation is triggered when bacterial or viral infections affect the bronchi, activating the body's immune system and increasing the synthesis of CRP to combat pathogens. This condition is often accompanied by symptoms such as coughing, expectoration, chest tightness, and fever. Doctors may prescribe medications such as amoxicillin capsules, ambroxol hydrochloride oral solution, and dextromethorphan hydrobromide tablets to control inflammation and alleviate symptoms.
Elevated CRP levels may be caused by intense physical activity, late pregnancy, acute bronchitis, pyelonephritis, rheumatoid arthritis, and other conditions. If abnormalities are detected, timely medical consultation is recommended. Detailed explanations are as follows:
1. Intense physical activity: High-intensity exercise places the body in a state of stress, stimulating the liver to accelerate CRP synthesis, leading to elevated levels. After stopping the exercise and allowing appropriate rest, the body recovers to a stable state, and CRP levels gradually return to normal. Daily exercise should focus on moderate intensity.
2. Late pregnancy: As gestational weeks increase, hormonal changes occur in the pregnant woman's body, and adaptive adjustments in the immune system may cause a physiological rise in CRP. This is a normal phenomenon that requires no special treatment; regular prenatal checkups to monitor health status are sufficient.
3. Acute bronchitis: Bacterial or viral infection of the bronchi triggers acute inflammation, activating the body's immune system and increasing CRP synthesis to combat pathogens. Symptoms often include coughing, sputum production, chest tightness, and fever. Doctors may prescribe amoxicillin capsules, ambroxol hydrochloride oral solution, dextromethorphan hydrobromide tablets, etc., to control inflammation and relieve symptoms.
4. Pyelonephritis: Pathogenic bacteria invading the renal pelvis and kidney parenchyma cause infection, and the inflammatory response leads to elevated CRP levels. Symptoms often include frequent urination, urgency, painful urination, back pain, and fever. Typically, doctors may recommend ceftriaxone sodium for injection, levofloxacin tablets, sodium bicarbonate tablets, etc., and once the infection is resolved, CRP levels gradually return to normal.
5. Rheumatoid arthritis: The immune system mistakenly attacks the joint synovium, causing chronic inflammation, which leads to persistently elevated CRP levels, often accompanied by joint swelling, pain, and stiffness. Treatment may include methotrexate tablets, sulfasalazine enteric-coated tablets, prednisone acetate tablets, etc., under medical guidance to suppress the inflammatory response and lower CRP levels.
In daily life, maintaining regular作息 and diet, avoiding excessive fatigue, and enhancing physical resistance are recommended. If persistent elevation of CRP accompanied by discomfort symptoms is detected, prompt medical consultation and examination are advised to identify the underlying cause and implement targeted treatment.
