Whether pectus excavatum can affect work depends on two aspects. Firstly, if it is a mild case of pectus excavatum, with an index less than 3.25, such mild conditions do not cause significant compression on the heart or lungs, and the patient will not have too many work-related issues. However, if the pectus excavatum index is greater than 3.25 and the chest is sunken inward and backward, significantly compressing the heart and lungs, such a condition prevents the heart from fully relaxing and the lungs from fully expanding, which can impact the patient's activities. Besides the physiological impact, this condition can also significantly affect social interactions, especially for young children or adults. Some patients may suffer severe inferiority complexes, depression, and even suicidal tendencies, which, of course, will also affect their work capability and state. Therefore, for severe cases of pectus excavatum, it is recommended to wait until after treatment to return to work. Once the pectus excavatum is corrected, and the heart and lung functions are no longer compressed, and the appearance is normalized, the patient's work capability should be completely fine.
