Pituitary Dwarfism

Pituitary Dwarfism

Pituitary Dwarfism is a rare endocrine disorder that is caused by growth-hormone deficiency. The disorder can be caused by genetic conditions, head trauma, or the lack of a functioning pituitary gland, which is responsible for releasing growth hormone. Pituitary dwarfism affects individuals across the age range, but is most common in children. Common physical features of this condition include short stature, delayed puberty, thin arms and legs, small facial features, and potential delay in normal development.

Signs and Symptoms

The signs and symptoms of pituitary dwarfism may include:

  • Short stature
  • Delayed or Growth failure
  • Delayed puberty
  • Thin arms and legs
  • Small facial features
  • Delay in normal development (learning, crawling, etc.)


Pituitary dwarfism can be caused by several different genetic conditions, head trauma, or the lack of a functioning pituitary gland. The pituitary gland is responsible for the production and release of growth hormone which is essential for normal growth and development. When the pituitary gland does not produce enough growth hormone, pituitary dwarfism may occur.

Diagnosis and Treatment

Pituitary dwarfism can be diagnosed through a physical examination, as well as laboratory tests such as measuring serum growth hormone levels. Treatment of pituitary dwarfism may include medication and growth hormone therapy. Medications such as Levothyroxine may be prescribed to replace hormones may help alleviate symptoms of the disorder. Growth hormone injections may also be prescribed to help increase growth rate in individuals with pituitary dwarfism.
