An exaggerated forward curve of the upper back. There are three quite different kinds, affecting different ages for different reasons — and one simple question separates them.
Every spine curves. Seen from the side, the neck and lower back curve inward, and the upper back curves outward — that outward curve is kyphosis, and between roughly 20 and 45 degrees it is simply normal anatomy.
The word becomes a diagnosis when the curve exceeds about 50 degrees. At that point the upper back looks rounded, the shoulders sit forward, and in more marked cases there is a visible hump.
The dashed line traces what people actually notice: the upper back rounds forward, the shoulders follow it, and the head ends up in front of the body rather than above it.
That last part explains a symptom people rarely connect to their spine. Holding the head forward of its natural position is constant work for the muscles of the neck and upper back, which is why fatigue and aching after standing are common complaints here — often more limiting than the appearance.
The highlighted section is thoracic, the part of the spine anchored by the ribs. That matters for treatment: it is the least mobile region of the spine, so a curve here cannot simply be stretched out.
It is a side-on curve, not a sideways one. Kyphosis is seen when you look at someone from the side. A curve seen from behind, where the spine deviates left or right, is scoliosis — a different condition. The two can occur together, but they are not the same thing.
Stand side-on to a mirror, then deliberately straighten up as tall as you can.
That distinction decides almost everything that follows: who it affects, how it progresses, and what is worth doing about it. It is also something you can check yourself before any appointment.
Mostly teenagers and young adults · flexible
The commonest by far. The spine is structurally normal but habitually held rounded — often from long periods at a desk or phone, or from self-consciousness about height.
It straightens when you ask it to, rarely causes significant pain, and does not progress to anything serious. It responds to strengthening and awareness rather than to bracing or surgery.
Begins in adolescence · structural
Here the vertebrae themselves grow wedge-shaped rather than rectangular during the growth spurt, so the spine is built with the curve in it.
The curve is rigid, often more angular than a postural one, and it can be genuinely painful — which helps distinguish it, since postural kyphosis usually is not.
Because it develops while the spine is still growing, this is the type where timing matters most. A brace can influence a curve that is still growing. It can do nothing once growth has finished.
Older adults · structural
The commonest kind in later life, and the one with a treatable cause underneath it. Osteoporosis weakens the vertebrae until they collapse at the front — compression fractures — and each wedged vertebra tips the spine a little further forward.
Disc flattening with age adds to it.
The curve is the visible sign of something worth treating in its own right. Finding it is often the first indication that bone density needs assessing.
Less commonly, kyphosis is present from birth because the vertebrae did not form properly, or follows injury, infection, surgery or conditions affecting connective tissue.
Where the curve is severe, it can begin to reduce the space available to the organs in front of it:
Kyphosis itself develops slowly. These suggest something more is happening:

Call +65 8849 0677Kyphosis treatment depends almost entirely on which of the three kinds it is, and on whether the spine is still growing. There is no single approach that fits all three.
Strengthening the muscles between the shoulder blades, stretching the chest and hip flexors, and changing the positions that encourage the rounding. Effective, and the curve is not going to become a structural problem — which is worth saying plainly, because people often fear it will.
A brace can influence a curve that is still growing, which makes this one of the few situations in spinal care where a window genuinely closes. Once skeletal growth is complete, a brace holds nothing in place. Physiotherapy remains useful for pain and function at any age.
The most useful thing here is often not spinal at all. Treating osteoporosis — medication, vitamin D, weight-bearing exercise — reduces the chance of further fractures, and it is further fractures that make the curve worse. Each one prevented is a degree of curve that never happens.
Anti-inflammatories for symptom control, and targeted physiotherapy in all three types — not to straighten the spine, but so the muscles cope better with the shape it is. This is the part of kyphosis treatment that applies regardless of which kind you have.
Considered where the curve is severe and worsening, where pain has not responded to anything else, where breathing is affected, or where the spinal cord is being compressed.
These are major operations, and the threshold for them is correspondingly high.
The value of an assessment here is that the three types look similar from the outside and are managed entirely differently.
Sometimes, and that is the commonest kind. Postural kyphosis is a normal spine held badly, and it straightens when you deliberately stand tall. If the curve stays when you try, the vertebrae themselves have changed shape and it is a different situation.
For postural kyphosis, largely yes. For structural kyphosis, exercise improves strength, pain and function but does not change the shape of the bones. Both are worth doing; they are just doing different jobs.
Postural kyphosis does not progress to anything serious. Scheuermann's can progress while the spine is still growing. Age-related kyphosis progresses if further compression fractures occur, which is exactly why treating the underlying bone matters.
Only while the spine is still growing, and mainly in Scheuermann's kyphosis. In adults a brace does not change the curve, though it can occasionally help short-term pain.
Usually it is the age-related kind, driven by osteoporosis and compression fractures. It is worth having her bone density checked, because treating the osteoporosis reduces the chance of further fractures and further curving.
No. Bring any X-rays, and note whether you can straighten the curve voluntarily, whether it has changed recently, and whether you have lost height.

The three kinds of kyphosis look alike from the outside and are managed quite differently. Establishing which you have is the first useful step.
