Does Pectus Excavatum Get Worse With Age?

Pectus excavatum (PE) is often diagnosed during childhood or adolescence. In many cases, the physical shape of the chest stabilizes after skeletal maturity, usually around the age of 18. However, even if the structural appearance of the chest does not significantly change, symptoms may become more noticeable as a person gets older.

Many individuals who experienced little or no discomfort in their teenage years begin to notice physical limitations in their 30s, 40s, or later. Understanding the difference between structural progression and symptom progression can help explain why this happens.

Structural vs. Symptomatic Progression

Structural Stability After Adolescence

Once skeletal maturity is reached, the chest wall generally becomes more rigid and the depth of the pectus excavatum indentation tends to remain relatively stable. The rib cage and sternum harden as bone growth completes, which usually prevents dramatic structural changes.

However, in some cases, the depression can continue to deepen slightly during adulthood, particularly if posture, muscle imbalance, or connective tissue factors contribute to the condition.

Symptoms May Still Worsen

Even when the physical indentation remains unchanged, symptoms can worsen over time. This occurs because the body gradually loses some of its ability to compensate for the reduced space inside the chest cavity.

As the body ages, the heart and lungs may become less adaptable to compression, which can lead to increasing physical discomfort and reduced exercise capacity.

Why Symptoms Can Increase With Age

Several physiological changes contribute to worsening symptoms in adults with pectus excavatum.

Increased Chest Wall Rigidity

As people age, the chest wall becomes less flexible and more rigid. In younger patients, the heart can often shift slightly to the left to avoid compression from the sunken sternum.

Over time, this flexibility decreases. As the chest wall stiffens, the heart may experience greater compression, which can affect circulation and cardiac function.

Increased Strain on the Heart and Lungs

Pectus excavatum can place pressure on the right chambers of the heart, potentially reducing cardiac output. When combined with the natural decline in cardiovascular efficiency that occurs with aging, this compression may lead to symptoms such as fatigue, reduced stamina, and difficulty exercising.

Postural and Muscular Changes

Changes in posture and muscle tone can also influence how noticeable the condition becomes. For example, forward-shoulder posture or weakened back muscles may make the chest depression appear more pronounced and contribute to discomfort.

Common Symptoms in Adults With Pectus Excavatum

Adults with pectus excavatum may gradually develop or notice an increase in symptoms such as:

• Shortness of breath, especially during physical activity

• Fatigue and reduced exercise tolerance

• Heart palpitations or irregular heartbeats

• Chest pain or a feeling of tightness in the rib cage

• Lightheadedness or dizziness during exertion

• Decreased overall stamina

These symptoms can vary significantly from person to person. Some individuals experience only mild limitations, while others may notice a substantial impact on their daily activities.

Late-Onset Symptoms in Adults

Clinical observations show that pectus excavatum is not only a pediatric condition. Some individuals do not develop noticeable symptoms until much later in life.

In studies of older patients, including individuals over 50, a significant portion reported that their symptoms only became severe in their 40s or 50s. In some cases, these symptoms are initially misdiagnosed as unexplained cardiovascular problems or general heart failure before the underlying chest wall deformity is identified.

Treatment Options for Adults

For many years, corrective treatment was primarily recommended for younger patients. Today, however, adults can also benefit from treatment.

Both surgical procedures—such as the Nuss procedure or the Ravitch procedure—have been successfully performed in adult patients, often leading to improvements in breathing, exercise tolerance, and overall quality of life.

In selected cases, non-surgical treatment approaches, including vacuum bell therapy and physical rehabilitation, may also help improve chest wall mobility and appearance.

Final Thoughts

While the structure of pectus excavatum often stabilizes after adolescence, symptoms can still develop or worsen later in life due to changes in the chest wall, heart, and lungs.

If symptoms such as shortness of breath, fatigue, or chest discomfort begin to appear, consulting a healthcare professional with experience in chest wall deformities can help determine the best management approach.

Early evaluation and appropriate treatment can significantly improve both physical function and quality of life for adults living with pectus excavatum.
