The most common causes of back pain in older adults are structural and degenerative changes in the spine — primarily degenerative disc disease, facet arthropathy, spinal stenosis, and osteoporotic compression fractures. These conditions develop gradually over decades, and by the time a person reaches their late sixties or seventies, one or more of them are often already present. According to the National Health Interview Survey, back pain affects 45.6% of adults aged 65 and older, with chronic low back pain affecting 37.3% of those 75 and older — making it one of the most prevalent physical complaints in aging populations.
Consider a 72-year-old woman who notices increasing stiffness when she gets out of bed each morning, along with aching in her lower back that worsens after walking more than a block. She may be experiencing a combination of degenerative disc disease and early spinal stenosis — two conditions that frequently overlap and compound each other. What often surprises people is that back pain in older adults is rarely caused by a single dramatic event; it is almost always the accumulation of years of wear on spinal structures, combined with the body’s reduced capacity to repair itself. This article covers the major structural and physiological causes of back pain in older adults, the risk factors that accelerate its development, and how it affects daily functioning and quality of life.

What Are the Most Common Structural Causes of Back Pain in Older Adults?
Degenerative disc disease is among the most frequently identified structural causes of back pain in aging adults. Between each vertebra sits a disc that acts as a shock absorber — filled with a gel-like interior and surrounded by a tough outer ring. Over time, these discs lose water content and elasticity, becoming thinner and less capable of cushioning movement. The result is increased pressure on surrounding structures, reduced range of motion, and chronic low-grade pain that often worsens with prolonged sitting or standing. Facet arthropathy — sometimes called facet joint syndrome or spinal osteoarthritis — is another primary contributor. The facet joints are small joints at the back of each vertebra that guide spinal movement and prevent excessive rotation.
As cartilage in these joints deteriorates, bone begins rubbing against bone, producing inflammation and pain. Unlike disc-related pain, which tends to be felt more centrally, facet arthropathy often produces pain that radiates to the buttocks or upper thighs and is typically worse when bending backward. Both conditions are considered mechanical in nature, and together they fall under the broader umbrella of non-specific mechanical causes, which account for approximately 90% of all back pain cases across age groups. Spinal stenosis, another major cause, involves the narrowing of the spinal canal — the channel through which the spinal cord and nerve roots run. As the canal narrows, often due to bone spurs, thickened ligaments, or disc bulging, nerves become compressed. The signature symptom is neurogenic claudication: leg pain, weakness, or numbness that comes on with walking or standing and is relieved by sitting or bending forward. An older adult who can walk two blocks but must stop to rest — and finds relief leaning on a shopping cart — is displaying a textbook presentation of lumbar spinal stenosis.
How Does Bone Loss Lead to Back Pain Through Compression Fractures?
Osteoporotic vertebral compression fractures represent a distinct and often underrecognized cause of back pain in older adults, particularly women. Osteoporosis causes bone density to decline to the point where vertebrae become fragile enough to fracture under ordinary stresses — not just falls, but actions as routine as lifting a grocery bag or sneezing. These fractures most commonly occur in the mid-to-lower thoracic spine and can cause sudden, sharp back pain that is quite different from the chronic ache associated with disc or joint degeneration. What makes these fractures especially significant is their potential to go undiagnosed for weeks or months. Older adults sometimes attribute the pain to a pulled muscle and delay seeking evaluation.
Meanwhile, multiple fractures can accumulate, leading to progressive kyphosis — the forward rounding of the upper spine commonly called a dowager’s hump — as well as a measurable loss of height. A woman who has lost two inches in height over a decade and notices increasing stooped posture may have sustained several compression fractures without ever experiencing a major traumatic event. However, it is important to note that not all compression fractures cause severe pain. Some are found incidentally on imaging taken for other reasons. If an older adult has osteoporosis and reports a sudden change in back pain character — especially if it is sharp, localized, and associated with any movement — that should prompt evaluation rather than assumption that it is routine musculoskeletal pain. The distinction matters because treatment differs substantially from that used for disc or joint-related pain.
What Role Does Muscle Loss Play in Geriatric Back Pain?
Sarcopenia — the progressive age-related loss of skeletal muscle mass and strength — is an emerging focus in geriatric back pain research. The muscles of the back, particularly the paraspinal muscles that run along the spine, play a critical role in stabilizing the vertebral column during movement and load-bearing. As these muscles atrophy and become infiltrated with intramuscular fat, the spine loses much of its dynamic support, placing greater mechanical stress on the discs, joints, and ligaments. Research has begun linking sarcopenia not just to general frailty and fall risk but specifically to the development and worsening of low back pain in older populations.
A 70-year-old man who has become increasingly sedentary following retirement, spending more hours sitting and less time in physical activity, may be experiencing the compounding effects of both disc degeneration and paraspinal muscle loss. The pain he feels is partly structural and partly a function of the spine working without adequate muscular support. This is one reason why treatment approaches that focus exclusively on imaging findings can miss the full picture. An MRI may reveal disc degeneration, but that finding alone does not explain why pain has worsened recently. If sarcopenia is also present and contributing, interventions that address muscle conditioning — such as physical therapy targeting core and paraspinal strength — may provide meaningful relief that purely structural treatments would not.
Which Risk Factors Accelerate Back Pain Development in Aging Adults?
Age itself is the most significant risk factor, but it does not act alone. Obesity places disproportionate mechanical load on the lumbar spine, accelerating disc degeneration and facet joint wear. Smoking has been associated with reduced blood flow to spinal discs, impairing their ability to absorb nutrients and repair minor damage — a less obvious but well-documented contributor to disc disease progression. Physical inactivity allows the muscles that support the spine to weaken over time, while high-demand physical jobs — particularly those involving repetitive lifting, bending, or vibration — can cause cumulative mechanical trauma that manifests as pain decades later. Women face elevated risk compared to men, partly because of osteoporosis prevalence after menopause and partly due to hormonal influences on joint and connective tissue health.
Comorbidities including diabetes and cardiovascular disease are also associated with higher rates of chronic back pain, likely through mechanisms involving impaired circulation, systemic inflammation, and altered pain processing. This comorbidity connection is particularly relevant for dementia care contexts, where patients often carry multiple chronic conditions simultaneously. Psychological factors deserve mention as well. Depression and anxiety, which are common in older adults dealing with chronic illness or isolation, are known to amplify pain perception and reduce pain tolerance. Age-related changes in how the central nervous system processes pain signals — a phenomenon called central sensitization — mean that pain in older adults may not be proportional to the degree of tissue damage visible on imaging. This is an important tradeoff to understand: treating back pain purely at the structural level, without addressing psychological and neurological contributors, often produces incomplete results.
When Does Back Pain Become a Functional and Quality-of-Life Problem?
The functional consequences of back pain in older adults extend well beyond physical discomfort. An estimated 60% of individuals with back pain experience functional disability and diminished quality of life — figures that translate to millions of people whose independence is compromised by a condition that is frequently undertreated or mismanaged. Difficulty with basic activities such as walking, climbing stairs, dressing, and cooking can trigger a downward spiral in which reduced mobility leads to further deconditioning, which in turn worsens pain. For individuals with cognitive impairment or dementia, the challenge is compounded. A person with moderate dementia who cannot reliably communicate the location or intensity of their pain may instead express it through behavioral changes — agitation, refusal to walk, changes in sleep, or increased resistance during care.
Caregivers and clinicians who are not attuned to this possibility may misattribute these behaviors to the dementia itself rather than undertreated pain. Back pain in this population is both underreported and undertreated for exactly this reason. A critical warning: the U.S. spends $100 billion annually on back pain-related costs, yet much of that spending goes toward imaging, procedures, and medications that may not address the root drivers of pain in older adults. Overuse of opioid analgesics in older populations carries significant risk — including falls, cognitive side effects, and dependence — and should not be a first-line response to chronic low back pain. The evidence base for conservative management, including physical therapy, gentle exercise, and targeted lifestyle modifications, is substantially stronger than it is for most interventional approaches in this age group.
How Does the Brain-Back Pain Connection Relate to Dementia and Cognitive Health?
There is a growing body of evidence suggesting that chronic pain and cognitive decline share overlapping neurological pathways. Persistent pain places a chronic stress load on the central nervous system, contributes to disrupted sleep, and has been associated with accelerated cognitive decline in some longitudinal studies. For caregivers supporting a loved one with dementia, understanding that unmanaged back pain can worsen behavioral symptoms — and potentially accelerate neurological decline — adds urgency to pain assessment and management.
Conversely, the medications used to manage back pain carry their own cognitive risks. Muscle relaxants, certain anticonvulsants used for neuropathic pain, and opioids are all on the Beers Criteria list of potentially inappropriate medications for older adults, in part because of their adverse effects on cognition and balance. The interaction between pain management and cognitive health is genuinely bidirectional, and treatment decisions should reflect that complexity rather than treating back pain as a problem isolated from the rest of the patient’s health picture.
What Does the Future of Back Pain Management in Older Adults Look Like?
The research landscape for geriatric back pain is evolving. Increased attention to sarcopenia as a treatable contributor — rather than an inevitable byproduct of aging — is opening new avenues for intervention through nutrition, resistance training, and emerging pharmacological approaches. Pain neuroscience education, which teaches patients to understand the role of central nervous system sensitization in their experience of pain, is gaining traction as a component of multidisciplinary treatment and has shown promise in reducing pain catastrophizing and improving function.
For older adults and their caregivers, the practical takeaway is that back pain at 70 or 80 is not simply something to be endured. The conditions driving it are identifiable, and many are at least partially manageable. Early engagement with a geriatrician or physical therapist who understands the specific mechanics of aging-related spinal disease can make a meaningful difference in preserving mobility, independence, and quality of life through the later decades.
Conclusion
Back pain in older adults is predominantly caused by degenerative structural changes — disc disease, facet arthropathy, spinal stenosis, and osteoporotic compression fractures — along with the progressive muscle loss associated with sarcopenia. These causes rarely occur in isolation; most older adults with chronic back pain are dealing with a combination of structural and physiological contributors, further complicated by risk factors like obesity, inactivity, and comorbid conditions. With nearly half of adults over 65 affected, back pain is not a minor inconvenience but a major driver of functional disability and reduced quality of life.
For those in dementia care settings, recognizing and managing back pain takes on added importance given the bidirectional relationship between chronic pain and cognitive function. Effective management starts with accurate diagnosis — which means looking beyond imaging to assess muscle health, movement patterns, psychological factors, and medication risks. Conservative, multidisciplinary approaches remain the most evidence-supported path forward, and early intervention consistently produces better outcomes than deferring treatment until pain has become severely limiting.
Frequently Asked Questions
Is back pain a normal part of aging?
Back pain is extremely common in older adults, affecting nearly half of those over 65, but it is not an inevitable or untreatable part of aging. Many of its causes are identifiable and at least partially manageable with appropriate intervention.
What is the difference between degenerative disc disease and spinal stenosis?
Degenerative disc disease refers to the breakdown and thinning of the discs between vertebrae, causing pain and stiffness. Spinal stenosis is a narrowing of the spinal canal that compresses nerves, producing pain and weakness that typically worsen with walking and improve with sitting or bending forward. The two conditions frequently coexist.
Can back pain in older adults be a sign of something serious?
Most back pain in older adults is mechanical in nature, but certain warning signs — called red flags — warrant prompt evaluation. These include pain following a fall or trauma, pain that is severe and unrelenting, fever with back pain, unexplained weight loss, or new bowel and bladder changes. These could indicate fracture, infection, or malignancy.
How does osteoporosis cause back pain?
When bone density drops to the level of osteoporosis, vertebrae become fragile and can fracture under minimal stress. These compression fractures cause sudden localized pain, loss of height over time, and spinal curvature. They are more common in postmenopausal women and can occur without any obvious trauma.
Why might a person with dementia not report back pain?
People with moderate to severe dementia may lose the ability to accurately describe pain. Instead, pain may manifest as behavioral changes — increased agitation, withdrawal, refusal to move or participate in care, or altered sleep. Caregivers should consider unmanaged pain as a potential explanation for unexplained behavior changes.
Is surgery usually necessary for back pain in older adults?
The large majority of back pain in older adults does not require surgery. Conservative treatments including physical therapy, targeted exercise, anti-inflammatory medications (used cautiously), and pain neuroscience education are first-line approaches. Surgery may be appropriate for severe spinal stenosis with significant neurological compromise or for unstable compression fractures, but is generally reserved for cases that have not responded to conservative care.
