What to watch with Ferritin and Darmgesundheit?

Ferritin is a key marker for iron stores, but it is also an acute-phase reactant, meaning it rises with inflammation—potentially masking true iron deficiency. In gut health issues like celiac disease, Crohn's disease, or ulcerative colitis, iron absorption may be impaired, leading to low ferritin. Conversely, chronic gut inflammation can artificially elevate ferritin, so concurrent testing of CRP or fecal calprotectin is advisable. Gastrointestinal bleeding also depletes ferritin. Interpretation always requires clinical context; a single ferritin value without inflammatory markers can be misleading. For unclear results, consult a physician.
