Your spine isn’t a single bone — it’s a flexible column made up of individual bones called vertebrae. Most people have 7 cervical (neck) vertebrae, 12 thoracic (mid-back) vertebrae, 5 lumbar (lower back) vertebrae, and a tailbone (the sacrum and coccyx). Between these vertebrae are cushions of cartilage called discs, or intervertebral discs. These 23 discs are small but mighty — they absorb shock, allow flexibility, and help protect your spine during all your daily movements.

At our Downtown Syracuse chiropractic clinic, we often help patients understand how these discs work — and how to keep them healthy for life.


What Is a Spinal Disc?

A spinal disc is a tough, flexible cushion that sits between each vertebra. Think of it like a jelly donut — with a soft, gel-like center (the nucleus pulposus) surrounded by a tougher outer ring (the annulus fibrosus). These discs act as shock absorbers, protecting your spine when you walk, run, lift, or even sit.

Over time, discs naturally lose some of their water content. In fact, they make up about 25% of your spine’s height when you’re young, but as you age, they slowly dehydrate and shrink. This loss of height can narrow the openings where your spinal nerves exit, a condition known as stenosis — which can cause pain, numbness, or weakness if those nerves become irritated.


How Everyday Movement Affects Your Discs

The pressure inside your discs changes constantly depending on your posture and activity. When you’re lying down, the pressure is very low. Sitting or standing increases that pressure 2–5 times, and lifting a 44-pound object can raise it 10–20 times higher than at rest!

That’s why lifting posture matters — bending your knees and keeping your back straight can cut disc pressure in half compared to bending at the waist. Keep this in mind the next time you pick up a box, a bag of mulch, or even your grandchild.

Our Syracuse chiropractors often teach patients proper lifting and movement techniques to protect their discs from unnecessary strain.


Keeping Your Discs Healthy

Healthy habits can go a long way in maintaining disc health:

  • Stay Hydrated: Discs are mostly made of water, so drinking plenty of fluids keeps them supple and strong.
  • Don’t Smoke: Smoking reduces blood flow and disc hydration, making discs more prone to injury and degeneration.
  • Move Regularly: Gentle stretching, walking, and good posture all help pump nutrients into your discs and joints.
  • Lift Smart: Always lift with your legs, not your back — and hold objects close to your body.

At our Downtown Syracuse chiropractic office, we emphasize daily habits that promote spinal wellness. Simple changes can make a lasting difference in your spine’s health and flexibility.


How Doctors Assess Disc Health

While X-rays don’t show the discs themselves, they do show the spaces between your vertebrae. Narrow spaces often mean a disc has degenerated or lost height. To see discs directly, doctors use MRI scans, which provide detailed images of the spine’s soft tissues. However, keep in mind that not all disc changes cause pain — studies show that many people without symptoms still have bulging or dried-out discs. A good doctor will look at your entire clinical picture, not just imaging results, before recommending treatment.

Our chiropractors in Syracuse take a conservative, evidence-based approach — focusing on movement, posture, and function before recommending more invasive options.


How Chiropractic Care Can Help

Chiropractic adjustments help restore normal movement to the joints that guide spinal motion and can improve the flow of nutrients to the discs. Regular chiropractic care not only helps relieve existing back pain but may also reduce the risk of future disc problems.

If you or someone you love is struggling with disc-related back pain, don’t wait. Our Downtown Syracuse Chiropractic team can help you understand what’s going on and get you back to pain-free living.
