”During my 30‐year carrier as an internist with a special interest in thyroid diseases and hematology, I have met hundreds of patients, mainly menstruating females, who seek advice because of prolonged (1–25 years) fatigue, brain fog, muscle and joint pains, weight gain, headache, dyspnoea, palpitations, sometimes associated with sleep disturbances, arrhythmia, lump in the throat or difficulty in swallowing, and restless legs. The patients have often received a spectrum of diagnoses, such as subclinical hypothyroidism (treated with levothyroxine alone or with T3 containing preparations), chronic fatigue syndrome, fibromyalgia, chronic Lyme disease, burnout, and overtraining. The blood count has usually been normal. At referral, their serum ferritin concentrations have ranged from 1 to about 150 μg/L. If there has been no obvious reason for iron deficiency, such as celiac disease, multiple blood donations, multiple pregnancies, or long periods of abundant menstruation, the differential diagnostics at serum ferritin >50 μg/L has included liver and kidneys diseases, occult blood in stools, IgA deficiency, calcium disorders, D‐vitamin or vitamin B12 deficiency and, if the history revealed prolonged use of pyridoxine (>20 mg/daily, vitamin B6 toxicity 14.”
