Hypothyroïdie

The hypothyroïdie is a situation of insufficient impregnation of the organization in thyroid hormones, generally because of a faulty operation of the Thyroid gland. This disease more often affects the Femme S.

ICM10

  • ICD 10 = E00-E03, E89.0
  • ICD 9 = 243-244

Causes

The causes are multiple. The great majority is represented by the primary hypothyroïdie, in other words a dysfunction on the level of the gland Thyroïde even. The secondary hypothyroïdie is due to a dysfunction of the pituitary gland which secret then in insufficient quantity the TSH or hormone of stimulation of thyroid the . Lastly, very rare case, the hypothyroïdie can be due to a peripheral resistance to the thyroid hormones.

Etiology

The cause is primarily an attack of the gland Thyroïde (hypothyroïdie primary), the secondary hypothyroïdies and resistance to the thyroid hormones being much rarer.

Primary Hypothyroïdie

  • deprives chronic of Iode
  • thyroidite autoimmunitaire (whose Thyroïdite de Hashimoto)
  • causes Iatrogène (thyroidectomy with the radioiode)
  • infiltrative disease (Sarcoïdose, Amyloïdose, Hémochromatose…)
  • enzymatic disorder of thyroid (genetics) the
  • congenital disgenesis of thyroid the

Secondary Hypothyroïdie

  • hypophyseal insufficiency
  • hypothalamic lesion
  • deficit in TRH

Peripheral resistance to the thyroid hormones

Symptomatology

The symptoms of the hypothyroïdie are: tire, frilosity, Myxœdème, reduction in pilosity, cramps muscular, hyperlipemy, constipation, reduction in the appetite, slowness of ideas, Goiter, more rarely, a Hypoglycémie.

Treatment

It will call most of the time upon a substitution thyroid day laborer in hormones by oral way.

The iodine addition in cooking salt is an effective measure to prevent the iodine deficiency, in particular in the countries in the process of development.

Tracking néonatal

The congenital hypothyroidie is detected systematically with the birth avoiding the formerly named disease Crétinisme. It is the origin of the “cretin of the Alps” of the Capitaine Haddock, dependant, in old times, with an iodine deficiency, frequent in these areas far away from the sea where salt of mine was consumed.
