Kyphosis is a spinal condition characterized by an excessive outward curvature of the upper back, leading to a hunchback appearance. It can occur at any age but is most common in older adults, often due to degeneration of the spine or conditions like osteoporosis. In children and adolescents, kyphosis may result from developmental issues or diseases such as Scheuermann's disease. Treatment options vary based on severity and may include physical therapy, braces, or surgery in more severe cases. Regular check-ups with a healthcare provider can help manage the condition effectively.
