What is degenerative disc disease?

Discs lose water with age. As they do, they lose height. The annulus (the tough outer ring) stiffens and cracks, and the vertebral endplates (the caps above and below each disc) change. That process is close to universal past the fourth decade. It shows up on imaging in huge numbers of people who have never had back pain.

So “degenerative disc disease” describes normal aging tissue that has been given the grammar of a disease. It is not an infection. It is not a tumor. And it does not follow a fixed downhill path toward a wheelchair, which is the fear almost everyone walks in with.

When does degenerative disc disease cause pain?

• An annular fissure (a crack in the outer ring) that reaches the outer third of the disc, where the nerves are. It can hurt with long bending forward and sitting.
• Endplate inflammation — Modic changes — one of the few disc findings that lines up reasonably well with symptoms.
• Secondary facet overload. As the disc loses height, the joints behind it are pushed closer together. These joints are often the real source of pain. Facet syndrome.
• Foraminal narrowing from lost height, which squeezes a nerve root as it exits. Radiculopathy.

Three of those four can be treated without touching the disc. That is the practical point of the list.

Why do some discs degenerate faster than others?

The disc is the largest avascular structure in the body (it has no blood vessels). It is fed entirely by diffusion, as nutrients seep in across the endplates. That route is open to the same processes that damage small vessels elsewhere — hyperinsulinemia (too much insulin in the blood), dyslipidemia (abnormal blood fats), smoking. Endplate calcification blocks the supply line directly.

Meanwhile, glycation (sugar binding to protein) cross-links the collagen of the annulus. That makes it stiffer and more likely to crack under loads it used to handle. And discs refill with water overnight, while you lie down. So short or broken sleep means starting each day with a disc that has not fully recovered from the last.

Genetics play a substantial part. But the share you can change is larger than most people are told. That is why bloodwork shows up on a back pain visit here.

Do my back and my heart share the same problem?

Often. The lumbar discs are fed by small arteries that branch off the aorta. When those calcify, the disc downstream starves. A 2024 review of 27 studies found aortic calcification tied to disc degeneration in 7 of the 21 that looked, and blood lipids tied to it in 8. The disc on your MRI and the plaque in your arteries can be one process.

For years I told prediabetic patients their A1C was “not too bad.” I was wrong, and this is part of why: the insulin and blood fats that narrow a coronary artery narrow the vessels a disc depends on. A disc aging faster than the rest of you is a reason to check your metabolism, not only your posture.

The jobs that load discs hardest, such as driving, warehouse work and nursing, usually come with the least sick time and the least room to stop and walk.

What is the best treatment for degenerative disc disease?

Manage load instead of avoiding it, since the disc adapts to demand and wastes away without it. For most people, favor extension (bending backward), because bending forward is the direction that provokes pain. Treat sleep as the repair window it is. And address the metabolic terrain, because a structural plan built on an inflamed terrain falls short.

When the facets or a nerve root are the real source, those can be treated directly, and the disc finding is a bystander. That happens more often than people expect.

What happens at a visit for degenerative disc disease?

Bring the report and the images; we read them against your exam. In a review of 3,110 people with no back pain, disc degeneration showed on imaging in 37% of 20-year-olds and 96% of 80-year-olds. The question is which structure, if any, matches what you feel.

The exam loads the facets, tests the nerve roots and checks the sacroiliac joints and hips. Bloodwork sits next to it, because glucose, insulin and lipids decide how well a disc is fed. A suspected facet joint is confirmed with a numbing block, done awake with local anesthetic; you drive yourself home and resume normal activity within two to four hours.

Does degenerative disc disease need surgery?

Rarely, and almost never as the first move. In two merged Norwegian trials, 124 patients with chronic low back pain and degenerated discs were randomized to spinal fusion or to a cognitive and exercise program. At four years the results were the same, and 23% of the fusion group had needed another operation. Fusion is a destructive operation: it removes motion permanently and moves the load to the levels above and below.

Surgery has a place when a disc presses on a nerve root and weakness is getting worse. That is a decompression such as a microdiscectomy, which Dr. Padda performs when indicated, not a fusion. For the aching disc without that, procedures are the bridge that makes the loading, sleep and metabolic work possible.

Orthobiologic treatment options

When a disc is proven to be the pain source, PRP or bone marrow concentrate placed inside the disc is an option we offer. A 2025 low back guideline from a national pain society rated both as fair evidence with a moderate recommendation. This is not an epidural. The concentrate goes into the disc itself, under X-ray. Results depend on picking the right disc, the dose we deliver, and the core work that follows.

You stay awake with local numbing, and most people drive home. The procedure is done at our regenerative clinic, 4477 Woodson Rd in St. Louis. Hip pain often travels with disc pain after 50. See hip arthritis and hip bursitis.

When is back pain with a degenerated disc an emergency?

• Loss of bladder or bowel control, or numbness in the groin and inner thighs.
• New weakness in a leg or a foot that is getting worse over days.
• Back pain with fever, especially with diabetes. In a review of 915 cases of spinal epidural abscess, diabetes was the most common risk factor, 71% began with back pain and 66% had a fever.

Frequently asked questions

Is degenerative disc disease progressive?

The imaging changes generally get worse slowly with age. Symptoms do not follow that curve. Many people have fewer symptoms over time as a segment stiffens and settles. The disc has no blood supply and is fed by diffusion, which is where metabolism comes in.

Will I end up in a wheelchair?

Almost never from this. How degenerate a spine looks on a scan and how a person functions are only weakly linked.

To learn why a scary scan predicts so little about function, read what your MRI actually showed.

Should I stop running or lifting?

Usually not. Loaded tissue is healthier tissue. Technique and a slow, steady build-up matter. Avoiding load costs you the muscle support the segment depends on.

Can you recover from degenerative disc disease?

Yes, in the way that matters: symptoms. How your discs look on a scan and how you feel do not track together. Many people hurt less over time as the segment stiffens and settles. When pain does come from degeneration, the source is often a facet joint or a pinched nerve root. Both can be treated directly without touching the disc.

What should you not do with degenerative disc disease?

Do not stop loading your spine. Discs adapt to demand and waste away without it. For most people, long stretches of sitting and bending forward are the positions that provoke pain, so break them up. Do not shortchange sleep, because discs refill with water overnight while you lie down. And do not smoke, since smoking damages the diffusion route the disc depends on for nutrition.

Is degenerative disc disease genetic?

Partly. Genetics play a substantial part, but the share you can change is larger than most people are told. The disc has no blood supply of its own. It is fed through the endplates, a route damaged by high insulin, abnormal blood fats and smoking. Sugar-driven cross-linking also stiffens the disc wall. That is why bloodwork is part of a back pain visit here.

What are the four stages of degenerative disc disease?

There is no formal four-stage system; the four stages found online come from patient-education charts, not from a medical classification. Radiologists grade disc degeneration on MRI with the Pfirrmann scale, grades I to V, and older surgical teaching describes three phases: dysfunction, instability and stabilization. None of those grades predicts how much a person hurts, so a grade on a report is not a treatment plan. In the stabilization phase the stiffening segment often hands its load to the facet joints behind it, which is where the pain then comes from.

Do I need a referral to see you about degenerative disc disease?

No. You can book directly; some insurance plans want a referral on file, so check yours. Bring your MRI report and the images if you have them. How to read the words on that report.

Movement feeds a worn disc, and the cat and cow exercise is one gentle way to keep a stiff, aging spine moving between visits.
