At what age does Pectus Excavatum appear or become apparent?

Pectus excavatum, also known colloquially as "shoemaker's chest", is a condition in which the rib cage is caved inwards. This structural deformity is often present at birth, but can become more pronounced to varying degrees at various stages of life. The question of when pectus excavatum appears or when it becomes more pronounced is an important curiosity for affected families and individuals. In this article, we will focus on the ages at which pectus excavatum appears or becomes more pronounced.

Existant from Birth

Pectus excavatum is usually a congenital condition. In newborn babies, it may start as a slight depression of the rib cage. However, at this early stage, pectus excavatum almost always goes unnoticed, as the severity of the condition is often mild.

Childhood and Adolescence

Pectus excavatum becomes most noticeable during the period of rapid growth in children. In particular, puberty is a critical point when this condition becomes more noticeable. During the growth spurts of puberty, the rib cage and ribs expand rapidly, while in some cases the inward collapse of the sternum may become more pronounced. These changes can exacerbate both the aesthetic and physical effects of the deformity.


Pectus excavatum usually does not progress after puberty; however, the deformity that becomes apparent in adolescence remains fixed in adulthood. In adulthood, when physical development is complete, the deformity is not expected to progress, but the physical and psychological effects of the condition may persist.

Predisposing Factors

Physical Activity and Exercise: Regular exercise and physical activity can have positive effects on the appearance of the deformity, especially by strengthening the chest and back muscles. While such activities may not reduce the severity of the deformity, they can improve overall body posture and muscle tone, helping to make the condition less aesthetically prominent.

Weight Changes: Significant changes in body weight, especially obesity, can affect the shape of the rib cage and therefore the appearance of pectus excavatum.


Pectus excavatum is a condition that begins early in life and becomes especially prominent during adolescence. This is when the deformity is most noticeable, both aesthetically and physically. Once adulthood is reached, the condition usually remains stable, but the effects on a person's quality of life persist. For affected individuals and families, early diagnosis and appropriate management strategies play an important role in reducing the effects of this condition.
