The pituitary
gland is the gland involved in dwarfism. It is a major endocrine gland, about
the size of a pea. The gland is a small membrane attached to the base of the
brain. This gland controls growth and development in individuals. When the
pituitary gland fails to produce enough hormones for growth and development,
the result is a disease called, Pituitary Dwarfism, also known as growth
hormone deficiency. If a child has a growth hormone deficiency, his/her growth
pattern is slow compared to his peers and his/her stature is below average
height.
