welche blutwerte bei erschöpfung — what symptoms are typical?

For exhaustion (fatigue), typical blood values include ferritin (iron stores), vitamin B12, folate, vitamin D, complete blood count (hemoglobin, red blood cells), and thyroid parameters (TSH). Low ferritin indicates depleted iron stores – even with normal hemoglobin, this can cause fatigue. Vitamin B12 deficiency is common in vegans/vegetarians and leads to exhaustion, concentration issues, and neurological symptoms. Vitamin D deficiency is also linked to chronic fatigue. Typical symptoms of exhaustion are persistent tiredness, lack of energy, poor concentration, irritability, and reduced performance. Important: blood values alone are not diagnostic – sleep quality, stress, diet, and psychological factors also matter. DNA tests can indicate genetic risks for nutrient deficiencies but do not replace blood testing. For persistent exhaustion, a doctor should interpret results in context.
