What causes gigantism?
Gigantism is caused by an overproduction of growth hormone (GH) that occurs in childhood before the bone growth plates have closed. Diseases, disorders and conditions that can cause GH overproduction leading to gigantism include:
- Benign tumors of the pituitary gland, which press on the pituitary gland and cause excessive GH production. This is the most common cause of gigantism.
- Carney complex (rare gene mutation that causes a high risk of certain tumors including pituitary adenoma)
- McCune-Albright syndrome (syndrome caused by a gene mutation)
- Multiple endocrine neoplasia type 1 (inherited disorder that causes tumors to form in endocrine glands and makes them hyperactive)
- Neurofibromatosis (genetic disorder causing tumor growth)
What are the risk factors for gigantism?
Gigantism is a very rare disorder. The main risk factor for gigantism is having a parent or sibling with gigantism.

How is gigantism treated?
Treatment of gigantism may involve a combination of techniques to reduce or regulate the pituitary gland’s release of growth hormone (GH). The exact treatment plan will vary based on the underlying cause of the overproduction of GH. Your healthcare provider is best able to guide your treatment decisions based on your specific circumstances.
