Suggestion: We must pay attention to how children's chicken breasts are caused. The answer to the question you mentioned about how children's chicken breasts are caused is as follows. Hello! Chicken breasts may be caused by rickets or congenital thoracic dysplasia. The chicken breast caused by rickets is due to the lack of vitamin D in the body, which affects the absorption of calcium and leads to poor ossification, showing various physical deformities. In addition to the common chicken breast, knee varus, knee valgus (that is, O-leg, X-leg), rib valgus, square skull and so on can also occur. The above symptoms can appear two or three months after birth. Children with the above manifestations should first ask whether they take cod liver oil, calcium tablets, etc. Follow the instructions of the doctor in infancy. There are also some rare "metabolic rickets". Even if you take cod liver oil and calcium tablets according to the doctor's instructions, you can still have symptoms of rickets, which requires special examination by a specialist. Children with rickets should first supplement vitamin D and calcium. After rickets is controlled, braces can be used to correct it, and surgery can also be considered in severe cases. If rickets is ruled out by blood drawing and X-ray examination, it may also be caused by congenital factors, and sometimes the specific reasons are not clear. For children under 5 years old, besides physical exercise, you can also try some orthoses for orthopedics. Severe children over 3 years old can also consider surgical correction. However, the operation involves a wide range, and the children's activities need to be restricted for a long time after operation to ensure thoracic healing. After orthopedic treatment, the appearance of normal children may not be reached. Therefore, the operation is limited to some children whose appearance deformity is very serious, or whose chest deformity seriously oppresses the heart and lungs, which affects the heart and lung function. If the problem is not serious, your child should receive medication. Please contact me if your local medication is ineffective. I wish your child a healthy growth!
