What Defect Causes Pituitary Dwarfism

What Defect Causes Pituitary Dwarfism

The condition in which the stature of an individual is lesser than that of an average adult is called dwarfism. It is usually characterized by an adult height of fewer than 4 feet 10 inches.

Pituitary Dwarfism:

The term pituitary dwarfism defines a condition where the growth of a person is retarded due to a defect in the pituitary gland. The pituitary gland is one of the major hormone-producing glands of a human body. It is this gland that is responsible to produce one of the most critical hormones, which is the growth hormone. Hence, what defect causes pituitary dwarfism is answered in more detail further.

What Defect Causes Pituitary Dwarfism:

A common query regarding this condition is what defects cause pituitary dwarfism. The foremost cause is the genetic factor. This condition may be passed on from generation to generation and there is not much one can do about it.

Another answer to the question as to what defect causes pituitary dwarfism is accidental trauma that affects the pituitary gland, as a result of which the gland produces insufficient quantities of the growth hormone. Thus, contributing to pituitary dwarfism.

The discussion over what defect causes pituitary dwarfism may come down to a possibility that the pituitary gland gets affected during a surgery due to which it stops producing the growth hormone or the quantities of hormone produced get disrupted.

Another addition to what defect causes pituitary dwarfism includes a tumor or a trauma in the central nervous system. As the pituitary gland is present in the central nervous system, any trauma may directly affect the production of growth hormone from the pituitary gland leading to pituitary dwarfism.

It is also possible that one may not figure out an answer to the question of what defects cause pituitary dwarfism. Sometimes the cause remains unidentified. Such a condition is termed as idiopathic dwarfism.

Symptoms of Pituitary Dwarfism:

A child suffering from pituitary dwarfism usually has a chubby body and an immature face. Their growth curve does not match other children of their age. If a tumor near pituitary gland is the defect that causes pituitary dwarfism, then children may suffer vomiting, dizziness, headaches, and may also complain problems in vision. The major symptom of pituitary dwarfism remains their growth compared to their peers.


Pituitary dwarfism is characterized by inadequate growth hormone in the body that is responsible for the normal growth of a person. Therefore, this condition does not surface until the child grows enough where the retarded growth starts presenting itself. The doctors ensure that the delays in growth are not due to any other underlying factors before declaring the condition as pituitary dwarfism.


The most common treatment of pituitary dwarfism is the hormone replacement therapy where the individual is treated with a hormone that is deficient, in this it is the growth hormone.

What defect causes pituitary dwarfism is hence the inadequate quantities of growth hormone being the produced by the pituitary gland and can be addressed by hormone replacement therapy.
