Inflammation is the most common cause of high CRP levels.
Acute infections, such as bacterial and viral infections, can cause a rapid increase in CRP levels.
Chronic inflammation due to conditions such as autoimmune disorders, cancer, and cardiovascular disease can also cause elevated CRP levels.
Lifestyle factors such as smoking, poor diet, and lack of exercise can also contribute to chronic inflammation and elevated CRP levels.
Treating the underlying cause of inflammation is key to lowering CRP levels, and may involve lifestyle changes, medications, or other interventions depending on the specific condition.
