If your sternum is suddenly sticking out, it might indicate a condition known as pectus carinatum, also referred to as 'pigeon chest.' It can develop due to rapid bone growth during puberty, poor posture, or it might have always been present but only recently became noticeable. However, it's important to consult a healthcare professional for an accurate diagnosis. Treatment might involve wearing a brace to correct the shape or, in rare cases, surgery. Addressing underlying posture issues can also help.
