Explain the Hyposecretion or Hypothyroidism during Infancy

Decreased secretion of thyroid hormone results in the development of the condition known as cretinism. There is a lack of skeletal development and stunted body growth. The child is mentally retarded due to lack of development of the nervous system. The skin is thick and dry, and the face is expressionless. Pulse and respiration rates are slow, there is a general sluggishness of all the body processes. Cretins are different from pituitary dwarfs as along with the stunted growth, they have mental retardation.
