When do children with achondroplasia stop growing?

Children with achondroplasia typically stop growing in height around the age of 18, as this is when most individuals reach their final adult height. However, the growth pattern can vary, and some may experience earlier or slightly later growth cessation. Generally, their growth rate slows significantly after the age of 2-3 years. Despite their shorter stature, individuals with achondroplasia often have normal proportions in other areas of their bodies.
