Hypothyroidism in children as well as adults, divided into primary and secondary. Primary hypothyroidism may be congenital (cretinism) and acquired (juvenile hypothyroidism). Hypothyroidism is the most common endocrine disorders in children.
Why and how the children there hypothyroidism
Reasons acquired hypothyroidism in children are the same as in adults. Congenital Hypothyroidism develops when the thyroid hypoplasia, as well as in violation of the biosynthesis of thyroid hormones

a defect in uptake of iodide by the thyroid gland and some other parts of the process.
Development of diseases associated with a lack of iodine in the body of the baby hormones. For congenital hypothyroidism is characterized by underdevelopment of the gonads, pronounced changes in the skeletal system: delay of growth and ossification of the skeleton, skull deformation, infringement of cartilage ends (epiphysis) of long bones.
These changes occur in children who become ill at an early age. Hypothyroidism at an early age also leads to a delay in brain development and dystrophic phenomena in the nerve cells of the cortex, medulla and cerebellum.
Symptoms of hypothyroidism in children
Some children with congenital hypothyroidism
Congenital hypothyroidism: start treatment as soon as possible
at birth weighs more than four kilograms, physiological jaundice have is their protracted, later than usual there is no umbilical cord, the formation of a hernia.
These children do not take the breast. The three - four months noteworthy lethargy and indifference of the child, he did not know the mother is not interested in toys skin pale, dry, cold to the touch, typical characteristic of hypothyroidism puffiness. Revealed a delay in growth and stunted physical and mental development. Children at the usual time do not hold a head, do not sit down. Go to start after only two - three years. Head compared with the body of a large, large fontanelle remains open in children older than two years. Teething is late, they are quickly destroyed.
Hair sparse, dry, brittle. The voice is low, rough, abdomen enlarged, wind (flatulence), characterized by constipation.
Growth has slowed sharply, the points of ossification appear late. Often there is a rare heart rate (bradycardia), low blood pressure. There is mental retardation, slowness, lethargy, apathy, sometimes aggression, mental disorders are possible. The degree of severity of disorders, such as swelling of the skin can be different.
When purchasing hypothyroidism developed after six - ten years, the symptoms are the same as in adults, but is usually less severe.
Diagnosis of hypothyroidism in children
If congenital hypothyroidism is extremely important early diagnosis, since timely treatment ensures normal physical development and improvement of brain activity.
However, due to the late onset of symptoms of hypothyroidism is rarely detected before the age of six months. Correct diagnosis contributes to the appearance of the characteristic clinical picture: elevated levels of cholesterol in the blood, reducing the level of iodine in it, bound to a protein
Reducing the primary exchange is of lesser diagnostic value. Correct diagnosis confirms the effectiveness of thyroid hormones. It is sometimes difficult to distinguish between congenital hypothyroidism from rickets. In congenital hypothyroidism exhibit peculiar dry skin

these features are not available.
Changes in bone point in congenital hypothyroidism in children who become ill at an early age, usually to five - six years.
Radiologically, a sharp slowdown in growth and calcification of bones. The later started treatment with thyroid hormones, the sharper expressed these changes. The skull is relatively large part of his brain increased anteroposterior direction is shortened from top to bottom. Facial skull is deformed to form a drawn but the nose. All points of ossification of the skeleton appearing as an afterthought. Delay ossification is clearly visible on X-ray of hand and wrist. X-rays not only helps to identify the bone changes in hypothyroidism, but is a valuable method of monitoring treatment outcomes.
Treatment of hypothyroidism in children
The main type of treatment is replacement therapy with thyroid hormones. Treatment should be initiated immediately after diagnosis, even when the suspected diagnosis. The dosage of drugs administered individually depending on the age and severity of symptoms.
Hypothyroidism in children is even more dangerous than in adults.
