Childhood pigeon chest, also known as rickets, is caused by a deficiency in Vitamin D or calcium, leading to bone development issues. If pigeon chest is suspected, it is advised to visit a hospital for a detailed examination and receive treatment accordingly. If the pigeon chest is quite pronounced and there is significant deformity of the chest wall, rehabilitation or correction can be sought in relevant medical departments. Rickets is typically active before the age of 3, and stabilizes after this age. Treatment primarily focuses on addressing rickets in cases identified before the age of 3, and correcting deformities in cases identified afterwards.
