Pectus Excavatum in Teens: When Appearance and Breathing Are Both Considered
Key Takeaways
- Pectus excavatum is a common chest wall deformity that can become more noticeable during the teen growth spurt.
- Some teens have no symptoms, while others notice shortness of breath, chest discomfort, or reduced stamina during exercise.
- Doctors evaluate both the chest shape and how the heart and lungs are functioning before recommending treatment.
- Treatment may include observation, posture and breathing support, vacuum bell therapy in selected cases, or surgery for more significant concerns.
- Emotional well-being matters too, especially when chest appearance affects confidence or social comfort.

Pectus excavatum is a chest wall shape difference in which the breastbone appears sunken inward. In teenagers, it may affect appearance, exercise tolerance, or self-confidence, and evaluation helps determine whether monitoring or treatment is appropriate.
Overview
Pectus excavatum is a condition in which the breastbone and the ribs around it grow inward, creating a visible depression in the center of the chest. Many families first notice it during the early teen years, when rapid growth makes body shape changes easier to see and the chest wall becomes more defined.
For some adolescents, the main concern is appearance. For others, the chest shape may be linked with symptoms such as getting winded more easily during sports, chest tightness, or a sense that deep breaths are harder to take. The important point is that pectus excavatum is not judged by appearance alone; doctors also consider how the heart and lungs are working and whether the teen feels limited in daily life.
Because teenagers are still growing, the timing of evaluation matters. A careful assessment can help families understand whether simple observation is enough or whether treatment should be discussed while the chest wall is still flexible.
Symptoms
The chest indentation itself is usually the most obvious sign. It may be shallow and subtle, or more pronounced and noticeable when the teen is shirtless or wearing fitted clothing. The shape can become more visible during growth spurts, when the ribs and breastbone do not expand evenly.
Not every teen has physical symptoms. When symptoms do occur, they may include:
- Shortness of breath or early fatigue during exercise
- Chest discomfort or pressure
- Reduced endurance compared with peers
- Palpitations or awareness of the heartbeat
- Poor posture or a tendency to round the shoulders
Emotional effects are also common. A teenager may avoid swimming, changing rooms, sports, or social situations because of self-consciousness. These concerns are real and deserve respectful attention, even when the medical impact appears mild.
Causes & Risk Factors
The exact cause of pectus excavatum is not always clear. It is thought to be related to how the cartilage that connects the ribs to the breastbone grows during childhood and adolescence. In some teens, this growth pattern causes the sternum to curve inward.
Family history can play a role, which suggests that inherited factors may contribute in some cases. Pectus excavatum can also appear alongside other connective tissue conditions, such as Marfan syndrome or Ehlers-Danlos syndrome, though many teens with pectus excavatum do not have these disorders.
Risk factors and related features may include:
- A family history of chest wall deformities
- Rapid growth during adolescence
- Long, slender body build in some cases
- Associated spinal or posture differences
It is useful for families to know that pectus excavatum is not caused by poor posture, sports participation, or any action the teen or parents did. While posture can make the chest appear more or less prominent, it does not create the deformity itself.
Diagnosis
Evaluation usually begins with a medical history and physical examination. The doctor may ask when the chest shape was first noticed, whether it is changing, and whether the teen has symptoms during activity, rest, or sleep. A family history and a review of growth patterns can also provide helpful clues.
Depending on the findings, further tests may be recommended to understand the effect on the heart and lungs. These may include imaging studies such as chest X-rays or computed tomography, and in some cases measurements that help estimate the depth of the chest depression. Heart and lung tests may also be used if there are symptoms suggesting reduced exercise tolerance.
Because many families are making decisions from another country, it helps to come prepared with any prior images, test results, and a list of symptoms, especially those related to sports, breathing, or chest discomfort. A well-organized review can make the consultation more efficient and reduce the need for repeat testing.
Treatment Options
Not every teen with pectus excavatum needs active treatment. If the chest shape is mild and there are no meaningful symptoms, doctors may recommend observation during growth, with periodic follow-up to watch for change. This approach is often suitable when the condition is stable and the teen is comfortable.
For selected patients, non-surgical treatment may be considered. Vacuum bell therapy uses gentle suction to lift the breastbone over time and may be helpful in some younger teens with flexible chest walls and specific chest shapes. Results vary, and it usually requires consistent use and regular medical follow-up.
Surgery may be discussed when the deformity is more pronounced, symptoms are present, or the teen experiences significant distress about appearance. Common surgical approaches aim to reshape the chest wall and improve its contour. The choice of treatment depends on age, severity, symptoms, growth stage, and family preferences after careful medical counseling.
When surgery is considered, the conversation should also include recovery planning. Families traveling from abroad need to think ahead about hospital stay, pain control, wound care, activity limits, and follow-up appointments after returning home. In this setting, a multidisciplinary team can help align the treatment plan with the teen’s school calendar and travel needs.
Prevention & Self-care
Pectus excavatum cannot usually be prevented, because it develops from growth and structural factors rather than from habits or injuries. Still, some self-care measures can support comfort, confidence, and overall health while the condition is being monitored or treated.
Helpful steps may include:
- Staying active with doctor-approved exercise
- Practicing posture awareness without forcing the chest
- Working on breathing exercises if recommended by a clinician
- Wearing clothing that feels comfortable and confidence-boosting
- Keeping follow-up appointments during growth years
Families should also pay attention to the teen’s emotional well-being. A supportive conversation about body image can be just as important as measuring chest shape. If self-consciousness is affecting school, sports, or social life, speaking with a doctor can open the door to both medical and psychological support.
When to See a Doctor
A medical evaluation is worthwhile if the chest indentation seems to be deepening, if a teen feels short of breath with activity, or if chest pain, dizziness, or reduced exercise tolerance is becoming noticeable. Even when symptoms are mild, an assessment can help clarify whether the heart and lungs are functioning normally.
It is also wise to seek advice if the appearance of the chest is causing distress, avoidance of physical activity, or embarrassment that affects daily life. Teenagers often minimize these concerns, but quality of life is an important part of care.
Families who are considering treatment from abroad may benefit from an early consultation so that imaging, specialist review, and recovery planning can be coordinated efficiently. Acibadem Health Point’s multidisciplinary specialists and JCI-accredited hospitals evaluate and treat pectus excavatum for international patients, with attention to both medical needs and the practical realities of travel and follow-up.
Living With Pectus Excavatum as a Teen
Living with pectus excavatum can feel different from one teen to the next. Some are mainly curious about their chest shape, while others feel self-conscious in settings where the chest is visible. Both experiences are valid, and neither should be dismissed.
Families often find it helpful to frame the condition as something to understand rather than hide. A clear diagnosis, a realistic treatment plan, and open communication can reduce worry. Teens usually cope better when they know what the deformity means, what symptoms matter, and what options exist if the shape or breathing becomes a concern.
For those who need treatment, outcomes are often best when care is planned thoughtfully during adolescence. The goal is not only a better chest contour, but also a plan that supports breathing, activity, and confidence in everyday life.
Frequently asked questions
Is pectus excavatum common in teenagers?
It is one of the more common chest wall shape differences seen in children and teens. Some cases are mild and only noticed during growth spurts, while others are more visible earlier in childhood. Many adolescents have no physical symptoms at all.
Can pectus excavatum affect breathing?
It can in some teens, especially if the chest indentation is deeper or if symptoms appear during exercise. Many teenagers breathe normally, but a doctor may check heart and lung function when shortness of breath or reduced stamina is reported. The presence of symptoms does not always mean a serious problem, but it does deserve evaluation.
Does poor posture cause pectus excavatum?
No, poor posture does not cause the condition. However, posture can make the chest appear more pronounced and may contribute to shoulder rounding or discomfort. Good posture habits can support comfort, but they do not correct the underlying chest wall shape.
What is the usual age for treatment decisions?
Treatment decisions are often made during the teen years, when the chest wall is still growing and the deformity can be assessed more clearly. The best timing depends on the severity, symptoms, and how much growth is still expected. A specialist can help determine whether monitoring or intervention is more appropriate.
Is surgery always needed?
No, surgery is not needed for every teen with pectus excavatum. Mild cases without symptoms may only require observation, and some selected patients may be candidates for non-surgical options. The decision is based on medical findings, symptoms, and the teen’s overall well-being.
Can teens continue sports and exercise?
In many cases, yes. Exercise is often encouraged if the doctor agrees it is safe, because staying active supports general health and confidence. If a teen becomes unusually short of breath, dizzy, or uncomfortable during activity, medical review is a good idea.
