My child is over 4 years old and has pectus excavatum. What should I do?

Patient's question:

Patient is male, 4+ years old, in good health
More than one year ago, the lower two ribs were found to be outwardly convex. Hospitals visited said the issue was due to calcium deficiency, so calcium supplements were given. This has been continuous, and now there is a sunken area in the sternum.

Doctor's answer:

The condition of the child is caused by rickets due to calcium deficiency in childhood. In this case, it is important to pay attention to calcium supplementation and also to supplement with vitamin AD for treatment. Additionally, it is advisable to have the child undergo a detailed examination at the hospital to check if there are any impacts on their appearance when they grow up. If necessary, appropriate cosmetic surgery can be considered.
