wie lange crp nach op erhöht — when to see a doctor?

After surgery, C-reactive protein (CRP) typically rises within 24–48 hours, peaking depending on the invasiveness of the procedure (e.g., 50–200 mg/L for major surgeries). In uncomplicated recovery, CRP declines over 3–7 days. A secondary rise or failure to decrease after 5–7 days may indicate a complication such as infection, wound dehiscence, or abscess. You should see a doctor if CRP increases again after an initial drop, if you develop fever, increasing pain, redness, or swelling at the surgical site, or if you feel generally unwell. A CRP persistently above 100 mg/L beyond one week also warrants evaluation. However, CRP alone is non-specific and must be interpreted alongside clinical signs. When in doubt or if additional symptoms appear, medical consultation is recommended. Evidence: human-strong (well-established postoperative kinetics).
