Stooped posture (kyphosis)

A stooped or hunched posture is an exaggerated forward curve of the upper spine (kyphosis), sometimes called a 'dowager's hump'. In younger people it is often postural — related to how one habitually sits and stands, weak or tight muscles, and prolonged desk or screen use — and can improve with posture and strengthening work. In older adults, however, a new or worsening stoop is an important sign, because a leading cause is compression fractures in the vertebrae. When bone is thinned by osteoporosis, the front part of one or more vertebrae can collapse into a wedge shape under the body's weight, sometimes without a memorable injury; each wedge tips the upper back further forward, producing a progressive stoop along with loss of height. So a rounding of the upper back that is new, getting worse, or accompanied by height loss, back pain, or a fracture from minor force points toward osteoporosis, which is common, silent until a bone breaks, and treatable. Other causes include age-related disc and joint changes, Scheuermann's disease in adolescents, and, rarely, other spinal conditions. Because osteoporosis frequently gives no warning, a visibly changing posture is one of the few outward clues worth acting on.

• Postural and muscle factors — habitual posture, weak or tight muscles, prolonged sitting; often improvable.
• Osteoporosis with spinal compression fractures — the key serious cause in older adults; wedged vertebrae tip the back forward.
• Osteopenia progressing to osteoporosis.
• Age-related disc and joint (degenerative) changes.
• Scheuermann's disease — a cause of kyphosis in adolescents.
• Vitamin D deficiency / osteomalacia — soft bones prone to deformity.

A stooped posture is assessed clinically and, when a spinal cause is suspected, with imaging (X-ray) to look for compression fractures and a bone-density (DXA) scan to assess for osteoporosis. Supporting blood tests check bone and mineral health and screen for treatable or secondary causes: calcium, vitamin D, phosphate, alkaline phosphatase, and parathyroid and thyroid function; protein tests if myeloma is a consideration. Mediora.AI can surface a vitamin D, calcium or bone-marker pattern that points to poor bone health from your results; confirming vertebral fractures or osteoporosis behind a changing posture needs imaging and a density scan arranged by your doctor.
