Hydration & MS: Why Water Matters, and How to Find Your Balance

Living with MS often means juggling symptoms, fatigue, bladder issues, temperature sensitivity — and sometimes, hydration is the unsung factor influencing it all. Many people with MS avoid drinking enough water to reduce bathroom trips, but dehydration can worsen fatigue, cognition, and overall symptom control. A better approach is to hydrate smartly rather than limit fluids altogether.
✅ Hydration Correlates with Fatigue
A study of 50 women with MS found that those with low hydration status (urine specific gravity, USG ≥ 1.015) reported higher fatigue scores compared to well-hydrated participants. PubMed
The authors noted that limiting water intake (often due to bladder dysfunction) may worsen fatigue in MS. PubMed
