How Dehydration Affects Spinal Discs: A Hidden Cause of Back Pain

When we think about dehydration, we usually associate it with fatigue, headaches, or dry skin. But did you know that dehydration can directly impact your spine and lead to back pain?

Your spinal health is closely connected to your body’s hydration levels. Let’s understand how.

What Are Spinal Discs?

Spinal discs are soft, cushion-like structures located between each vertebra in your spine. They act as shock absorbers, allowing flexibility and smooth movement.

Each disc has:

• Nucleus pulposus – a gel-like center (mostly water)
• Annulus fibrosus – a tough outer layer

Important: Spinal discs are made up of nearly 70–90% water.
