Malfunction of the thyroid:
The thyroid releases hormones that are responsible for regulation of the metabolic organ. Due to a thyroid hypofunction fewer triiodothyronines and thyroxines are released; the pulse decreases and people become tired. But, a hyperthyroidism, too, may lead to exhaustion. Here, the influenced organ functions and metabolic processes work at full steam. Symptoms like cardiovascular problems or the feeling of weakness and restlessness might occur. The concentration of the thyroid hormones in the blood and hence the function of the thyroid can be determined by a doctor.
Estimated 5-10 % of all Europeans suffer under iron deficiency. With women in childbearing age even 20-30 %. Reasons for iron deficiency might be a low iron nutrition, heavy periods, or a high loss of blood due to injuries or a surgery. Due to iron deficiency the red blood cells transport fewer oxygen into the body cells. A severe iron deficiency might cause tiredness, sleep disturbances, restless-legs-syndrome, head ache, concentration problems and hair loss.
To prevent iron deficiency care for a balanced diet. Meat, green vegetables, pulses contain iron. Vitamin C rich foods support iron absorption; coffee, black and green tea on the other hand inhibit the absorption.
