Obesity in childhood can lead to various health issues that may impact growth and overall development, and children who are obese often have a higher risk of continuing to be obese into adulthood. However, growth patterns can vary widely among individuals, and not all overweight children will experience the same adult height outcomes. It’s important to note that height can be influenced by many factors including genetics, nutrition, and overall health.
