Overview
Kyphosis is an abnormal, excessive outward curve of the spine, most commonly in the upper back (thoracic spine). When the curve becomes too large, the posture and mechanics of the spine and shoulders change, which can lead to pain, stiffness, and reduced functional endurance. In some cases, kyphosis is related to growth problems in childhood (such as Scheuermann disease) or to age-related changes in the vertebrae and discs, including compression fractures. Depending on the cause, kyphosis can also affect breathing comfort when the upper back curvature becomes severe.
Symptoms
Patients often notice an increased rounded appearance of the upper back, tightness, and a feeling of fatigue with prolonged sitting or standing. Pain may be felt in the mid-to-upper back and can worsen with activity, poor posture, or long periods in one position. Some people develop reduced flexibility when bending or extending the spine and may feel stiffness when waking up. If kyphosis is associated with nerve or spinal canal involvement, symptoms such as numbness, weakness, or balance trouble can occur, though this is not the most common presentation.
Causes
Kyphosis can develop from structural problems in the spine, including congenital differences, growth-related changes during adolescence (Scheuermann disease), or healing issues after a vertebral compression fracture. Degenerative changes from aging, such as disc degeneration and arthritis in spinal joints, can also gradually increase the curve. Osteoporosis and other bone-weakening conditions raise the risk of vertebral fractures that can worsen kyphosis over time. Less commonly, inflammatory conditions like ankylosing spondylitis can contribute to progressive spinal curvature and stiffness.
Risk Factors
Risk increases with aging, especially when bone density decreases or discs and joints wear down over time. Having adolescent growth-related kyphosis (such as Scheuermann disease) raises the likelihood of persistent or worsening curvature. Osteoporosis, prior spinal fractures, and long-standing poor posture with weak back and core endurance can also contribute. Genetics, inflammatory arthritis, and smoking (which can impair bone health) may increase risk.
Prevention
Maintaining strong back extensors, a stable core, and regular mobility work can help support healthy spinal alignment. Good ergonomics-such as monitoring screen height, taking posture breaks, and using supportive seating-may reduce prolonged strain on the thoracic spine. If you are at risk for osteoporosis, addressing bone health with appropriate exercise and clinician-guided management can help lower the chance of compression fractures. Avoiding smoking and supporting healthy nutrition, including adequate calcium and vitamin D when appropriate, can also support bone integrity.
How the Diagnosis Is Evaluated
Clinicians typically start with a detailed history about onset, progression, pain, posture habits, prior fractures, and any neurologic symptoms. A physical exam evaluates spinal alignment, flexibility, muscle tenderness, and (when relevant) strength, sensation, and reflexes to screen for nerve involvement. Imaging usually begins with standing X-rays to measure the curve and determine the likely cause, and additional views may be obtained to assess alignment. If there are red flags such as neurologic deficits, suspected fracture, or inflammatory disease, MRI or other testing may be recommended, and bone density testing may be considered when osteoporosis is a concern.
Nonsurgical Treatment Options
Non-surgical care focuses on reducing pain, improving mobility, and optimizing posture and spinal support. Physical therapy commonly emphasizes thoracic mobility, strengthening of the upper back and core, stretching of tight muscle groups, and training for better movement mechanics during daily activities. Bracing can be considered especially in growing adolescents with progressive curvature, helping slow worsening while growth continues. Pain control may include activity modification, heat or ice, and short-term use of anti-inflammatory medications if appropriate for you. When pain is localized and related to muscular tightness or facet/joint irritation, targeted trigger point injections or corticosteroid injections may be used to reduce symptoms and support participation in rehabilitation.
When to Seek Medical Attention
Seek prompt medical attention if kyphosis is rapidly worsening, if you have new severe back pain, or if you suspect a recent fracture (especially after minor trauma or with known osteoporosis). Get urgent evaluation for neurologic changes such as progressive weakness, numbness, trouble walking, or balance problems. Contact a clinician promptly if you develop bowel or bladder changes, fever, unexplained weight loss, or symptoms that suggest infection or a serious underlying cause. Also seek evaluation if breathing becomes noticeably difficult due to changes in upper back posture.
Frequently Asked Questions
Kyphosis refers to an excessive forward curvature of the spine, while normal posture variations may cause mild rounding without a pathologic increase in the curve.
In many cases, physical therapy helps reduce pain, improve posture control, and increase flexibility, even though it may not fully reverse structural curve changes.
Often, yes; addressing posture, strengthening the back and core, and managing bone health can reduce progression in many people, particularly when the underlying cause is treated.
Next Steps
If you have noticeable upper back rounding, persistent mid-back pain, or progressive posture changes, consider scheduling an evaluation with a clinician experienced in spine conditions. They can determine the likely cause, check for any neurologic or bone-health concerns, and recommend a tailored non-surgical plan such as posture training and physical therapy. If any red-flag symptoms are present, seek care sooner rather than later.
