Is it too late to improve pectus excavatum at 20, 30 or 40?
By Javier Santana, founder of Pectus Academy · Updated October 2026
Short answer: it is not too late to work on posture, breathing and muscle, which in general can be trained at any age. What does change is what you can expect from treatments that act on the bone: the vacuum bell has better evidence in children and very little data in adults, and surgery is still possible, with more bleeding and more acute pain than in minors according to one large study.
What changes with age?
| Stage | Posture and exercise | Vacuum bell | Surgery |
|---|---|---|---|
| Teenage years | Can be trained | The stage with the most evidence | Usually left until after the growth spurt |
| 20 to 39 | Can be trained; we found no pectus-specific studies | It has been used, with treatments of 24 to 36 months and uncertain results | Possible, with more bleeding and more acute pain than in minors |
| 40 and over | Can be trained; we found no pectus-specific studies | It has been used up to age 61; no results broken down by age | Possible; in one small series, complications in 31.3% |
The studies do not separate the 20s from the 30s. The table draws the lines they draw: teenagers, adults and people over 40.
Why does age matter for the vacuum bell?
The studies point to better results with a flexible chest, and a stiff chest wall is one of the reported factors for failure. It is usually assumed that the chest becomes less flexible with age, although that is not a finding from these studies.
Even so, the data disagree: in a study of 72 patients, starting at age 11 or younger was linked to better results; in the Amsterdam study, with 259, age was not significantly linked to success. The near-absence of adult data means nobody knows how well it works. We cover that in does the vacuum bell work in adults?
Does the pectus itself change?
It usually gets more pronounced during the growth spurt of puberty and can keep doing so into adulthood. We have not found data showing that it corrects itself.
At 20
Growth has finished or is finishing, and every option is still open. If you are considering the bell, published treatments in adults run 24 to 36 months, with medical follow-up. If you have symptoms or a marked pectus, it is a good time for a full evaluation.
At 30
The options are the same as at 20. In a registry of 2,843 patients who had surgery, adults had more bleeding (3% vs 0.86%) and more acute pain (55% vs 39.1%) than minors.
I started working on my posture at 33. In my case it changed how I perceive my body: I felt better about how I looked and better overall, with better posture and more confidence. That is my experience, not proof of what will happen to you.
From 40 on
In a series of 16 patients who had surgery at 40 or older, there were complications in 31.3%, and the authors conclude that age alone should not be a contraindication to surgery. The bell has been used in people up to age 61, with no results broken down by age.
Before using a bell, at any age, heart problems have to be ruled out: it is contraindicated in people with heart disorders.
When should you see a doctor, whatever your age?
If you notice shortness of breath, chest pain, palpitations, fainting, or you tire more than normal during exercise. An exercise test can reveal limitations that do not show at rest.
What we know and what we don't
What we know
- Surgery in adults is possible; in one large study they had more bleeding and more acute pain than minors.
- The bell has been used in adults up to age 61, with no outcome or safety data broken down by age.
What we don't know
- How well the bell works at each age.
- How much appearance changes with posture and exercise in adults: we have not found studies that measure it.
- Whether there is an age after which something stops being worthwhile: we have not found any study that sets that limit.
