Gigantism - Medical Glossary

Understanding Gigantism?

Gigantism results from an overproduction of growth hormone, usually caused by a benign tumor on the pituitary gland. It affects children and adolescents, causing abnormally rapid and excessive growth of bones and tissues.

Symptoms and Signs of Gigantism?

Common symptoms include unusually tall height, large hands and feet, facial changes, joint pain, delayed puberty, and excessive sweating. Children may also experience headaches and vision problems due to pressure from the tumor.

Causes and Risk Factors for Gigantism?

The most common cause is a noncancerous tumor (adenoma) on the pituitary gland. Rarely, genetic conditions like McCune-Albright syndrome or Carney complex may increase the risk. Early diagnosis is essential for better management.

Treatment Options for Gigantism?

Treatment usually involves surgery to remove the pituitary tumor. In some cases, radiation therapy or medications are used to control hormone levels. Regular follow-ups and hormone monitoring are necessary after treatment.

When to Seek Medical Help for Gigantism?

Consult a doctor if a child is growing unusually fast compared to peers, or if physical changes like enlarged hands, feet, or facial features are noticed. Early intervention can prevent long-term complications and improve outcomes.
