The duration of elevated CRP levels depends on the underlying cause and the effectiveness of treatment or management strategies. In acute conditions, such as an infection, CRP levels may rise rapidly and return to normal once the infection is resolved, which can take days to weeks. In chronic inflammatory conditions, such as autoimmune diseases, CRP levels may remain elevated for longer periods, fluctuating over time depending on disease activity. With appropriate treatment and lifestyle modifications, CRP levels can be controlled and reduced over time. Regular monitoring and follow-up with a healthcare professional are important to assess the progress and adjust the treatment plan if necessary.
