Key Highlights
Here are the key takeaways about what causes scoliosis in adults:
- Adult scoliosis involves a side-to-side curvature of the spine that is either a progression of a childhood condition or develops new in adulthood.
- The two primary types are adult idiopathic scoliosis, which continues from adolescence, and degenerative scoliosis, caused by age-related wear and tear on the spine.
- Significant hormonal changes, particularly during pregnancy and menopause, are a major factor in the development and progression of adult scoliosis.
- Symptoms often include lower back pain, uneven shoulders or hips, loss of height, and nerve-related pain in the legs.
- Genetics and family history can increase your risk, as can conditions like osteoporosis and previous spinal injuries.
- A range of scoliosis treatment options are available, from observation and physical therapy approaches like the Scoliosis Activity Suit, a Scoliosis Brace, or, in severe cases, scoliosis surgery.
Introduction
When you think of scoliosis, you might picture a teenager wearing a back brace. While it is often diagnosed in adolescence, it’s a condition that can also appear or worsen during adulthood. If you’re experiencing new or increasing lower back pain, stiffness, or noticing that your shoulders or hips seem uneven, you might be dealing with adult scoliosis. This condition is defined by an abnormal sideways spinal curvature that can impact your posture, comfort, and overall quality of life. Understanding the causes and symptoms is the first step toward finding effective solutions and getting back to the activities you love.
Understanding Adult Scoliosis
Adult scoliosis refers to any sideways curvature of the spine of 10 degrees or more in an individual who has completed their skeletal growth. Unlike the natural front-to-back curves of your spine, this condition causes it to bend left or right in an “S” or “C” shape. For some, this is a continuation of a curve that began in their youth, known as adult idiopathic scoliosis. For others, it develops later in life due to spinal degeneration.
The symptoms of scoliosis in adults are often more noticeable than in children, primarily because they frequently involve pain and nerve-related issues. You might wonder, are the causes of scoliosis different if you get it as an adult versus as a kid? The answer is yes, and these differences influence everything from symptoms to treatment. Let’s explore how adult scoliosis is distinct from its childhood counterpart and examine the two main types you might encounter.
How Adult Scoliosis Differs From Childhood Scoliosis
The primary distinction between adult and childhood scoliosis lies in the cause and symptoms. Childhood scoliosis is typically idiopathic, meaning the cause is unknown, and it’s often detected during routine school screenings or wellness checks. In many cases, it doesn’t cause pain. The main concern during youth is monitoring the curve to see if it progresses during growth spurts.
In contrast, adult scoliosis is often diagnosed because it has started to cause problems. The causes are more varied, ranging from the progression of an adolescent curve to the development of a new abnormal curvature of the spine due to aging and degeneration. While a child’s spine is still growing and flexible, an adult’s spine is mature, and any changes can lead to stiffness, nerve compression, and persistent pain.
Another key difference is the location of the curve. While adolescent scoliosis most commonly affects the thoracic (upper and middle) back, adult scoliosis is frequently found in the lumbar (lower) back. This is because the lower spine bears more weight and is more susceptible to degenerative changes over time, leading to symptoms like low back pain and leg pain that are less common in younger patients.
Types of Adult Scoliosis
When discussing adult scoliosis, it’s helpful to understand the two main categories: adult idiopathic scoliosis and adult degenerative scoliosis. Differentiating between them is key to determining the right course of action. Adult idiopathic scoliosis is simply a curve that was present during adolescence but may have gone undiagnosed or was not severe enough to require treatment at the time. Over the years, this existing curve can slowly progress or begin to cause symptoms in adulthood.
On the other hand, adult degenerative scoliosis, also known as de novo (new) scoliosis, develops in a previously straight spine. This type of scoliosis is caused by the natural aging process. As spinal discs and facet joints wear down and weaken, the spine can lose its stability and begin to shift and curve. This form is most common in adults over the age of 65 and typically occurs in the lumbar spine.
To make the differences clearer, here’s a simple breakdown of this common type of scoliosis versus the degenerative form:
| Feature | Adult Idiopathic Scoliosis | Adult Degenerative Scoliosis |
| Origin | Continuation of a curve from adolescence. | Develops new in adulthood due to spinal degeneration. |
| Primary Cause | Unknown (idiopathic). | Aging, arthritis, osteoporosis, disc and joint wear. |
| Common Location | Often in the thoracic (upper/middle) spine. | Almost always in the lumbar (lower) spine. |
| Typical Age of Onset | Symptoms can appear at any age in adulthood. | Most common in individuals over 65. |
Key Causes of Scoliosis in Adults
Understanding what causes scoliosis in adults is crucial for effective management. Unlike in children, where the cause is often unknown, adult scoliosis is frequently linked to specific biological processes and health conditions. The primary drivers are the progression of an existing curve from youth or the development of a new spinal curvature due to degenerative changes that come with age.
Is adult scoliosis usually caused by aging or other health conditions? Largely, yes. Factors like hormonal shifts, the natural wear and tear on your spine, and underlying health issues play a significant role. The following sections will provide a closer look at how these elements contribute to the development and progression of scoliosis in adults.
Hormonal Changes During Pregnancy and Menopause
Significant hormone changes are often a primary cause of scoliosis progression in adults. During major life stages like pregnancy and menopause, your body experiences dramatic hormonal fluctuations. These changes can affect the ligaments that support your spine, causing them to become more lax. This laxity can allow an existing, stable curvature of the spine to worsen or may even contribute to the development of a new curve.
During pregnancy, the body produces the hormone relaxin to prepare the pelvis for childbirth, but this hormone affects ligaments throughout the body, including those in the spine. Similarly, the drop in estrogen during menopause can accelerate bone density loss and weaken spinal structures. This is why many women first notice the symptoms of scoliosis, such as lower back pain and postural changes, during or after these life events. Yes, adults can absolutely develop scoliosis even if they didn’t have it as children, and hormonal shifts are a key reason why.
Because of this strong link, understanding your hormonal health is crucial. Scoliosis hormone testing is available to identify imbalances that could be contributing to your spinal issues. An easy-to-use home saliva collection kit can provide valuable insights for you and your doctor.

Aging, Degenerative Changes, and Other Health Factors
As you age, your spine naturally undergoes wear and tear. This degeneration of the spine is a leading cause of adult degenerative scoliosis. The discs that cushion your vertebrae can lose height and dry out, and the small joints that connect them can develop arthritis. These degenerative changes can cause the spine to become unstable and shift, leading to a curve, most often in the lower spine. This asymmetry is what leads to the characteristic symptoms of adult scoliosis, including chronic low back pain and sciatica-like leg pain.
This process directly answers the question: can degenerative changes in the spine lead to adult scoliosis? The answer is a definitive yes. It is one of the most common reasons adults with no history of the condition develop a spinal curve later in life. The gradual nature of this process means symptoms may appear slowly over time, eventually impacting your posture and mobility.
Beyond normal aging, other health factors can contribute to or cause adult scoliosis. These conditions can weaken the spinal column or disrupt its alignment, accelerating degenerative changes. Some of these factors include:
- A traumatic injury to the spine from a fall or accident.
- Tumors on or near the spine that exert pressure.
- Neuromuscular conditions like cerebral palsy or muscular dystrophy.
- Previous spinal surgery that may have inadvertently destabilized an area of the spine.
Risk Factors and Genetics for Adult-Onset Scoliosis
While aging and hormonal changes are direct causes, certain risk factors can make you more likely to develop adult-onset scoliosis. Are there any risk factors that make adults more likely to develop scoliosis? Yes, and genetics is a significant one. If you have a close relative with scoliosis, your chances of developing the condition are higher. This suggests a hereditary link that researchers are actively studying.
A family history of scoliosis doesn’t mean you will definitely get it, but it does mean you should be more aware of the potential signs and symptoms as you age. Beyond genetics, other health and lifestyle factors can also increase your risk. The following sections will explore the roles of family history, underlying health conditions like osteoporosis, and lifestyle choices in more detail.
Research strongly indicates that there are genetic factors involved in adult-onset scoliosis, particularly the idiopathic type that continues from adolescence. Studies have shown that scoliosis often runs in families. If you have a parent, sibling, or child with scoliosis, your risk of developing it is notably higher than that of the general population. This connection highlights genetics as one of the key risk factors.
While scientists have not yet identified a single “scoliosis gene,” they believe that multiple genes are likely involved in predisposing an individual to spinal curvature. This genetic link doesn’t just apply to adolescent idiopathic scoliosis. It may also play a role in how susceptible your spine is to degenerative changes later in life, potentially influencing the development of degenerative scoliosis.
It is important to remember that having a family history of scoliosis is a risk factor, not a diagnosis. Many people with a genetic predisposition never develop a significant curve. However, being aware of your family history allows you to be proactive. You can pay closer attention to changes in your posture or back pain and seek a professional opinion sooner rather than later, which can lead to better outcomes.
Impact of Osteoporosis, Injuries, and Lifestyle
Beyond genetics, other conditions and life events serve as major risk factors for adult scoliosis. Osteoporosis, a condition that causes bones to become weak and brittle, is a significant contributor. Can osteoporosis contribute to scoliosis in adults? Absolutely. When vertebrae lose density, they can become compressed or fracture, leading to a loss of height and causing the spine to curve and tilt. This is especially common in postmenopausal women, who are at a higher risk for osteoporosis.
Traumatic injuries can also directly cause scoliosis in adulthood. A severe fall, car accident, or other trauma can fracture or dislocate vertebrae, disrupting the spine’s alignment and resulting in a curve. Even less severe, repetitive injuries from certain sports or occupations can accelerate degenerative changes in the spine, contributing to the development of scoliosis over time and causing chronic lower back pain.
Certain lifestyle factors can also influence your spinal health and increase your risk. Making positive lifestyle changes can help support a healthy spine and potentially reduce the severity of symptoms. Key areas to consider include:
- Smoking: It is known to accelerate disc degeneration, weakening the spine.
- Sedentary Lifestyle: A lack of core strength can reduce support for your spine.
- Poor Nutrition: Deficiencies in calcium and vitamin D can contribute to bone loss.
- Obesity: Excess weight places additional stress on the spinal column and discs.

Frequently Asked Questions
Can adults develop scoliosis even if they didn’t have it as children?
Yes, adults can definitely develop scoliosis even with no childhood history of the condition. This is called adult degenerative scoliosis. The primary cause of this scoliosis is the natural aging process, which leads to wear and tear on the spinal discs and joints. This degeneration can cause the spine to become unstable and form an abnormal curvature of the spine. The symptoms of scoliosis often develop gradually and can be confirmed with a physical exam and imaging tests.
What symptoms suggest scoliosis may be developing in adulthood?
In adulthood, the most common symptom that suggests a developing curve of the spine is persistent pain, especially lower back pain that may radiate down into the legs. You might also notice changes in your posture, such as uneven shoulders or hips, a loss of height, or a feeling of being off-balance. In more advanced cases, you could experience numbness, cramping in the legs, or difficulty walking long distances.
How does hormone testing help identify adult scoliosis risk?
Hormone testing can be a valuable tool for identifying adult scoliosis risk because hormonal changes, especially during menopause, are a key driver of curve progression. By measuring specific hormone levels, a specialist can identify imbalances that may be weakening your spine’s supportive ligaments. This information, combined with your medical history and a physical exam, helps create a more comprehensive picture of your scoliosis risk and allows for a proactive and personalized treatment plan.
