Understanding Extreme Human Growth
Gigantism, the condition that affected Robert Wadlow, is a rare disorder characterized by excessive growth and height significantly above average. It is typically caused by a tumor on the pituitary gland, which produces too much growth hormone.
Key aspects of gigantism often include:
- Excessive Height: Uncontrolled growth of bones and other body parts.
- Delayed Puberty: Hormonal imbalances can affect normal development.
- Health Complications: Individuals often face significant health challenges, including cardiovascular issues, joint problems, and weakened immune systems, due to the immense strain on their body systems.
- Shortened Lifespan: The physical demands often lead to a shorter life expectancy.
Despite his challenges, Wadlow maintained a calm and cooperative demeanor, touring with circuses and promoting shoe companies that custom-made footwear for him.
