Panhypopituitarism is a condition caused by the limited functioning of the pituitary gland, leading to growth hormone deficiency, stunted growth, and other health problems. Symptoms vary by age, and treatment involves hormone replacement and addressing the underlying cause.
Panhypopituitarism is a growth hormone deficiency that can cause stunted growth, dwarfism, and other major health problems. This condition is caused by the shut down or limited functioning of the pituitary gland, which is located in the brain. Normally, this gland produces important hormones, but production can be disrupted due to cancer, genetics, or other factors. In adults, hormone deficiency can lead to obesity, low blood sugar, and general weakness. Panhypopituitarism in children is most noticeable due to the child’s stunted growth, which can be quite severe when the deficiency is left untreated.
The symptoms of panhypopituitarism vary depending on the age of the affected person. In infants, symptoms of this condition can include facial defects, ambiguous genitalia, and seizures. Older children with panhypopituitarism usually have symptoms such as an abnormally slow growth rate and slow sexual maturation. Panhypopituitarism in adults generally leads to obesity; changes in skin, hair, and nails; and a decrease in libido and sexual function. Many cases of this condition in adults go undiagnosed and therefore untreated; the person usually leads a relatively normal life, although it tends to be unnaturally short and rarely experiences sexual arousal.
Many conditions, injuries, and infections can lead to panhypopituitarism, but all can affect the pituitary gland in a way that leads to abnormally low hormone levels. One way the pituitary gland can be damaged is through a syndrome called Sheehan’s syndrome, which usually occurs as a result of blood loss during pregnancy and which leads to low blood pressure and cell death. Some people are born with this syndrome due to other associated conditions, problems during birth, or an unsuccessful development of the pituitary gland. Direct injuries to the brain, such as trauma, radiation therapy, and brain surgery, can also cause panhypopituitarism by damaging the pituitary gland.
One method of treating panhypopituitarism is to replace hormones that are not being produced. These treatments are highly dependent on how low the hormone levels are and the life circumstances the patient is currently experiencing. Often, hormone replacement therapies do not completely eliminate the problems caused by lack of adequate hormone levels and other associated conditions must be treated directly. Another important aspect of treating panhypopituitarism is correcting the original cause, which may involve surgery or radiation to fight a tumor, medications to fight infection, and other treatments for many possible underlying conditions.
