Pectus excavatum, often visible from birth, primarily worsens during the adolescent growth spurt.
Understanding Pectus Excavatum Progression
Pectus excavatum, commonly known as sunken chest or funnel chest, is a condition where the breastbone (sternum) appears to be caved in. While its presence is often evident shortly after birth, the degree of its severity can change over time.
The Impact of Adolescent Growth
The most significant period for the worsening of pectus excavatum is adolescence. During this time of rapid development:
- Increased Severity: As children undergo their adolescent growth spurt, their bones and cartilage grow at an accelerated pace. In individuals with pectus excavatum, this rapid and sometimes disproportionate growth of the rib cage and sternum can cause the breastbone to be pulled further inward, making the indentation more pronounced.
- Visible Changes: The cosmetic appearance of the chest can become more noticeable, and in some cases, the increased severity can lead to new or worsening symptoms, such as shortness of breath, chest pain, or exercise intolerance.
While the exact mechanisms are complex and relate to abnormal growth of the costal cartilages (the cartilage that connects the ribs to the sternum), the rapid changes in body size and skeletal structure during puberty are key factors in the progression of the condition.

Key Period of Progression
| Life Stage | Impact on Pectus Excavatum Severity |
|---|---|
| Infancy/Childhood | Often noticeable, but may remain stable or show slow progression. |
| Adolescence | Most significant period for worsening. Rapid growth can exacerbate the indentation. |
| Adulthood | Generally stable; significant worsening is less common after skeletal maturity. |
Understanding this progression is crucial for monitoring the condition and considering potential interventions, especially as the individual approaches or goes through puberty.
