Course of disease
Since the hair, as non-essential cells, is the first to be depleted, hair loss is often one of the first symptoms that those affected notice. In the next step, those affected often feel limp and tired. Relatives often respond to their pale, tired appearance.
Only when the deficiency is more severe do the specific symptoms, such as inflammation of the corner of the mouth, become apparent. After treatment, the symptoms often heal in reverse order. Accordingly, hair loss is often the last symptom to disappear. Without treatment, an iron deficiency can be a chronic situation and even with treatment, the course of the disease can drag on for several months.
