Degenerative disc disease, or DDD, is probably the most misunderstood diagnosis I encounter in my practice. Patients come in with their MRI report in hand, they see those words printed in black and white, and they panic. They've Googled it. They've read that their spine is "degenerating." It sounds like their back is slowly falling apart. In reality, degenerative disc disease is far more nuanced than that name suggests, and the good news is that the vast majority of people with DDD respond well to non-surgical treatment.

What Degenerative Disc Disease Actually Is

Let's start with some perspective. Disc degeneration is a normal part of aging. I'd estimate that most people over the age of 40 have some degree of it visible on an MRI. By age 60, you'll find disc degeneration in probably 80 to 90 percent of people if you image their spine. That's not pathology—that's aging. That's normal.

What we're talking about is the gradual loss of water content in the intervertebral discs as we get older. Discs are roughly 80 percent water when we're young. They're plump, resilient, full of fluid. Over time, especially with poor posture, heavy loading, and lack of movement, those discs lose hydration. They become less able to absorb and distribute load. The disc height decreases slightly. The fibers in the outer layer of the disc—the annulus—can develop small tears or weak spots.

On an MRI, this shows up as darker discs, loss of disc height, and sometimes a decrease in the normal curves of the spine. Radiologists call it "degenerative changes." Patients hear that and think their spine is broken. It's not broken. It's aged. There's a difference.

When DDD Becomes a Symptom

The problem is when that disc degeneration creates actual mechanical problems that cause pain. This happens when disc height loss is severe enough to cause foraminal narrowing—that's when the space where the nerve root exits the spine gets squeezed. Or when the facet joints, which are right behind the disc, start to overload and develop osteoarthritis themselves. That's when you go from having radiographic degenerative disc disease to having symptomatic degenerative disc disease.

The symptoms are pretty classic. You have chronic low back ache—not sharp or shooting, but a persistent, dull soreness. You notice it especially in the morning when you first get out of bed, or after you've been sitting at a desk for an hour. Your back feels stiff until you move around a bit. Some patients tell me that sitting for prolonged periods makes it worse, or that they have to shift positions frequently. Standing for a long time can trigger a slow build of discomfort.

What you typically don't have with pure DDD is shooting pain down your leg—unless there's enough nerve compression happening alongside the disc degeneration. Some patients do have that, but many don't.

Why Surgery Often Isn't the Answer for DDD

Here's something that surprises people: the surgical outcomes for fusion surgery—which is what's often offered for symptomatic degenerative disc disease—aren't actually that great compared to what you'd think given how invasive the surgery is. I've read a lot of the literature on this, and what it tells me is that fusion for DDD has poor long-term outcomes in many studies.

Don't get me wrong. Spinal fusion can be a good surgery for the right patient with the right problem. But using fusion to "stop" degenerative disc disease? That's like trying to stop aging. You can fuse one level, but the levels above and below will continue to degenerate—maybe even faster because they're now bearing extra load. The surgery has a recovery period of 6 to 12 weeks, there are real surgical risks, and somewhere between 5 and 15 percent of patients experience re-herniation. Some develop what's called "failed back surgery syndrome"—chronic pain despite the surgery—and that affects 10 to 40 percent of surgical patients depending on what study you read.

That's not anti-surgery talking. That's just the evidence. Surgery is a tool. For DDD alone, it's often not the right tool.

The Non-Surgical Approach: Restoring Function

What we do at West Hills Chiropractic is address the underlying mechanics without cutting anything. The cornerstone of our approach for DDD is spinal decompression therapy.

Here's the physiology: after age 20 or so, intervertebral discs are avascular. That means they don't have a blood supply anymore. They rely entirely on diffusion—on nutrients and oxygen slowly moving into the disc from the surrounding tissues based on a pressure gradient. When a disc loses height and becomes dehydrated, that diffusion becomes sluggish. The disc gets even more dehydrated. It's a downward spiral.

Spinal decompression interrupts that spiral. By creating negative pressure in the disc, we create a gradient that pulls nutrients and fluids back into the disc space. The disc rehydrates. The disc height improves. We're not "reversing" degeneration in the sense of turning back the clock, but we are improving the environment and allowing the disc to function better mechanically.

Alongside decompression, we use chiropractic care to restore joint mobility. The vertebrae above and below a degenerated disc often become stiffer and more restricted in their movement. Adjustments help restore normal motion and reduce the compensatory stress that the degenerated disc is bearing. We also address facet joint inflammation, which is almost always present alongside DDD.

Then there's the exercise piece. We work on core stability—and I mean real core stability, not just planks. We address hip mobility because tight hips force your lumbar spine to compensate. We correct postural habits that load the degenerative discs excessively. A patient with poor posture at their desk is loading their lumbar discs in a way that accelerates degeneration. Fix the posture, and you change the load.

Long-Term Management Over a Quick Fix

Here's something I'm honest about: we're not "curing" degenerative disc disease. That disc is still going to be degenerated ten years from now. What we're doing is managing it in a way that keeps you functional and prevents progression.

I think of DDD like type 2 diabetes. You can manage it aggressively with diet, exercise, and medication, and the patient does great. Or you can ignore it, keep eating poorly, and end up on multiple medications with complications. DDD is similar. If you actively manage it—keep up with your posture, do your core work, maintain your mobility, get periodic decompression therapy—you can function at a very high level and slow down the progression. If you ignore it and just push through, you're likely to get worse over time.

Most of our DDD patients see significant improvement within 4 to 6 weeks of regular decompression therapy combined with manipulation and exercise. They resume activities they haven't been able to do. They sleep better. They're not thinking about their back constantly.

Maintenance might look like periodic decompression therapy—maybe once a month or once every other month—combined with regular chiropractic care and a home exercise program. It's not a huge burden, and it's incomparably better than major spine surgery and all its risks.

When Surgery Might Actually Be Necessary

I'm not anti-surgery. Sometimes surgery is absolutely the right call. If you have cauda equina syndrome—that's compression of multiple nerve roots causing loss of bowel or bladder control—that's a surgical emergency. If you have a progressive neurological deficit—meaning you're actually getting weaker, not just more painful—surgery might be indicated. If you've done 6 to 8 weeks of aggressive conservative treatment including spinal decompression and you haven't seen meaningful improvement, and your pain is truly intractable, then a surgical consultation is reasonable.

But in our experience, the majority of patients with DDD who commit to the non-surgical protocol do see meaningful improvement. And I mean real improvement—not just learning to live with it, but actually feeling better and functioning better.

The Evidence Is There

The clinical evidence supports this approach. Non-surgical decompression therapy shows positive outcomes in 70 to 90 percent of appropriate candidates depending on which studies you look at. Zero downtime. No anesthesia risk. No recovery period. You can get decompression therapy on a Tuesday morning and be back to work in the afternoon.

Degenerative disc disease is a long-term condition, and long-term conditions are best managed with long-term strategies, not one-time surgical fixes. If you've been told you need surgery for degenerative disc disease and you're looking for alternatives, I'd encourage you to try non-surgical decompression therapy first. The evidence suggests you'll likely see real improvement.
