Growth hormone deficiency
Growth Hormone Deficiency
Growth hormone deficiency (GHD), also known as somatotropin deficiency or pituitary dwarfism, is a medical condition characterized by insufficient production of growth hormone (GH) by the pituitary gland.
Pronunciation
Growth Hormone Deficiency: /ɡroʊθ ˈhɔːrmoʊn dɪˈfɪʃənsi/
Etymology
The term "Growth Hormone Deficiency" is derived from the English language. "Growth" refers to the process of increasing in size, "Hormone" is a regulatory substance produced in an organism and transported in tissue fluids to stimulate specific cells or tissues into action, and "Deficiency" means a lack or shortage.
Definition
Growth hormone deficiency is a rare disorder involving the pituitary gland (a small gland at the base of the brain) which produces growth hormone and other hormones. When the pituitary gland does not produce enough growth hormone, growth will be slower than normal.
Symptoms
Symptoms of growth hormone deficiency can vary significantly among individuals. Some common symptoms include slow growth, delayed puberty, and a younger-than-normal appearance.
Causes
Growth hormone deficiency can be caused by mutations in specific genes, damage to the pituitary gland, Turner syndrome, Prader-Willi syndrome, or can be idiopathic (of unknown cause).
Diagnosis
Diagnosis of growth hormone deficiency involves a series of tests including blood tests, MRI scans of the brain, and growth hormone stimulation tests.
Treatment
Treatment for growth hormone deficiency typically involves daily injections of synthetic growth hormone. These injections help to stimulate growth and development.
