Hypothyroidism represents an increasingly diagnosed health condition that, while predominantly associated with adult populations, is also documented in medical literature as occurring during childhood and even the neonatal period. This endocrine disorder, characterized by insufficient synthesis of thyroid hormones, may exert significant effects on the physical and cognitive development of young individuals, thereby necessitating timely identification and comprehensive therapeutic interventions—including tailored nutritional modifications—to mitigate potential long-term consequences.
Discretion of the thyroid in children
It is also caused by a subcutaneous-pituitary-thoracic axis failure. Up to 85% of cases are sporadic (non-genetic, accidental), 15% autosomal recessive inheritance.[1] In addition, studies indicate that children who already have another coexisting disease unit, including type II diabetes or Down syndrome, are up to 3 times more likely to suffer from a subclinical form of inactivity [2].
Symptoms of hypothyroidism in children
Among the main symptoms that are seen in slightly older children, there are disorders of growth and inhibition of a child's mental development. It is also possible to observe a disorder of metabolism and sexual development that belongs to the patient's age. In slightly elderly children, the main signs indicating a sick individual are: fatigue, drowsiness, weakness, constipation, excess body weight in relation to growth.[2] Researchers note that it is not easy to diagnose abnormalities in newborns.
The diet of a child with hypothyroidism
Particular attention should be paid to: allergens, including gluten and lactose: it is best to test for intolerance to these food ingredients and to use an elimination-rotation diet; a diet rich in selenium, iron, zinc, vitamin D, calcium (i.e. the introduction of nuts, seeds and fungi, fermented protein products if no allergy, vegetables and fruits are present); a rich, rational diet.
