What should I do?” Chronic fatigue syndrome occurs in adolescence due to increased human activity. Psychoemotional stress on the human nervous system is the main cause of this disease. A feeling of fatigue and lethargy often occurs in adolescents during puberty. This can be due to poor nutrition, as well as a deficiency of vitamins and minerals, which are consumed especially intensively at this age. The specialist you should contact is a general practitioner. He can refer the patient to a specialist. Usually, you can cope with all the symptoms if you normalize the child’s daily routine, start eating right with the whole family, eliminate emotional and physical overloads, abandon too high a load at school and arrange an active family vacation more often.[/vc_column_text]
