Gravity never takes a day off. Neither do your discs.

One thing I talk about with patients all the time is the normal stress on the spine. Not an injury. Not one bad lift. Just the everyday wear and tear that comes from living with gravity.

Gravity pulls down on you every single day, and your spine is built to handle it.

How your discs protect you every day

Your spine has 24 movable bones, called vertebrae. Between those bones are your discs, and they act like cushions. Every time you bend, twist, or turn, those discs absorb and spread out the force. That's exactly what they're designed to do, and it's a good thing.

But think about how many times a day you bend, sit, stand, lift a child, or get in and out of the car. Then add gravity on top of all of it. Over the years, that repetition, along with normal aging, adds up.

What we see on an X-ray or MRI

On an X-ray, we can often see the effects, like the space between two bones getting narrower. An MRI shows the discs themselves. Over time, that wear can show up as a bulging disc, or as disc desiccation, which simply means the disc is losing water and drying out.

These changes are common, and they don't always cause pain. That's why we look at the whole picture.

Here's the easiest way I explain it. A healthy disc is like a wet sponge, full of water and able to cushion. A disc that has dried out is more like a dry sponge. It gets flatter and stiffer, and it just doesn't absorb force the way it used to.

How your discs get what they need

Your discs don't have much of their own blood supply. They soak up fluid and nutrients from the bone above and below them. When a disc is under load, that pressure squeezes water out. When the load comes off, the disc naturally draws water back in. It's one reason you're a little taller in the morning than at night.

How spinal decompression works

Gravity compresses the disc. Decompression does the opposite.

During your exam, we find the disc level with the most pressure and strain on it. Then we use gentle, rhythmic forces to stretch the spine right at that level and take pressure off the disc.

The goal is to give that disc a chance to relax, and room to draw fluid and nutrients back in over time, which is what a healthy disc needs.

Why your nerves matter most

At the end of the day, this is the most important part. Your discs and bones are there to protect the most important system in your body, your nervous system. That means the spinal cord and all the nerves that leave your low back.

Many of those nerves travel across your hips and down your legs, including the sciatic nerve. That's what most people feel, and it's often why someone with a disc problem notices pain, numbness, tingling, or tightness down the leg. If that sounds familiar, our sciatica and low back page talks more about it.

Nerves from your low back and pelvis also help run things your body does automatically. When we take pressure off those areas with decompression, and gentle adjustments where they are needed, our goal is to support how your whole nervous system works, not just how your back feels.

Why some patients keep coming for maintenance

People sometimes ask me, "If I feel better, why would I keep doing decompression?"

It's a fair question. A lot of patients feel so much better during their first phase of care that we have this conversation at the end. Here's my answer. The forces that created the problem don't stop. Gravity is still there tomorrow.

We may not need to be as aggressive or as frequent. But stretching that disc out a couple of times a month gives it room to breathe, and gives those nerves room to breathe too. It's about keeping your spine, your discs, and everything around them as healthy as possible for the long run.

Not sure if decompression is right for you?

That's exactly what our candidacy exam is for. We'll look at your history, take X-rays, and give you a clear, honest answer about whether decompression makes sense for you. No pressure.
