Definition
Growth hormone (GH) is a peptide hormone that stimulates growth, cell reproduction, and regeneration. It's secreted by the pituitary gland and is vital for development, especially during childhood and adolescence. GH promotes the growth of bones and cartilage. It also affects metabolism, helping the body use fat and carbohydrates. Think of GH as the body's "grow" button, ensuring things develop properly. Unlike insulin (which manages sugar), GH focuses on growing and repairing.
