Gigantism

Gigantism is an uncommon endocrine disorder that occurs in childhood or adolescence when the body produces excessive amounts of growth hormone (GH) before the growth plates close. This hormonal imbalance, most often caused by a benign pituitary adenoma, results in abnormal linear growth and significantly increased height compared to peers.

Children with gigantism may show rapid growth in height, enlarged hands and feet, coarse facial features, and delayed puberty. Other symptoms include headaches, vision problems due to tumor pressure, and joint pain from the strain of excessive growth. Beyond physical changes, gigantism can lead to serious health complications such as cardiovascular disease, diabetes mellitus, and musculoskeletal issues.

Diagnosis involves measuring GH and insulin-like growth factor 1 (IGF-1) levels, along with imaging studies like MRI to detect pituitary tumors. Treatment typically includes surgical removal of the adenoma, medical therapy to suppress GH secretion, and radiation therapy if surgery is not fully effective. Early detection is critical, as untreated gigantism can progress into acromegaly in adulthood, with irreversible changes.

With timely medical intervention and ongoing monitoring, children affected by gigantism can achieve better health outcomes, manage complications, and improve their quality of life.
