Giantism is a rare condition characterized by excessive growth and height due to an overproduction of growth hormone, often caused by a tumor on the pituitary gland. This condition typically occurs in childhood or adolescence, before the growth plates in the bones close, leading to significantly taller stature than average. Individuals with giantism may experience various health issues, including joint pain, cardiovascular problems, and diabetes. Early diagnosis and treatment, often involving surgery or medication to address the pituitary tumor, can help manage symptoms and improve quality of life.
