Can Dehydration Cause Back Pain? Here’s What Science (And Your Georgetown Chiropractor) Says

Most people know that dehydration causes headaches and fatigue—but did you know it can also lead to back pain? At Thomas Back & Body, your trusted Georgetown chiropractor, we’ve seen firsthand how a lack of hydration can contribute to spinal discomfort. If you’ve been wondering about the link between dehydration and back pain, you’re not alone—and science backs up the connection.

Dehydration and Back Pain: What’s the Link?

Your spine is made up of 33 vertebrae, separated by soft, gel-like discs that act as shock absorbers. These intervertebral discs are made up of about 70-80% water. When your body is dehydrated, these discs lose water content, becoming less flexible and less able to cushion your spine. That loss of fluid can lead to:

• Increased pressure on nerves

• Reduced shock absorption

• Spinal stiffness

• Muscle cramping or spasms

According to a study in the Journal of Anatomy, disc dehydration is a key factor in disc degeneration and chronic low back pain. While disc dehydration happens naturally with aging, poor hydration can accelerate the process—leading to more pain, more stiffness, and more visits to the medicine cabinet.

How Dehydration Affects Your Muscles and Joints

It's not just the discs that suffer. Dehydration also affects the muscles, ligaments, and fascia that support your spine. When your tissues don’t get enough water, they can become tight, inflamed, and more prone to injury.

Muscle cramps and spasms—especially in the lower back—are common signs that your body is low on fluids and electrolytes. Staying properly hydrated keeps these tissues flexible and reduces the risk of strain.

Signs You May Be Dehydrated (and Not Know It)

Many people are chronically mildly dehydrated without realizing it. Here are a few subtle symptoms that might be connected to your back pain:

• Fatigue or low energy

• Muscle tightness or cramps

• Stiffness after sitting or sleeping

• Headaches

• Dry mouth or dark urine

If these symptoms sound familiar, your water intake might need a serious boost.
