Fatigue is one of the most common and challenging symptoms of multiple sclerosis (MS), affecting about 80% of patients. Unlike regular tiredness, MS fatigue doesn’t improve with rest. It can hit suddenly and become overwhelming, making even simple tasks feel impossible.
The primary cause is damage to the nervous system, but secondary factors like poor sleep, pain, stress, and medication can worsen it. Symptoms may include brain fog, muscle weakness, and a feeling of exhaustion that worsens as the day progresses.
To help manage MS fatigue, try energy conservation strategies:
• Plan and prioritize tasks.
• Pace yourself to avoid over-exertion.
• Use assistive devices or position things nearby to minimize energy use.
• Allow yourself to rest and take breaks.
• Focus on nutrition, hydration, and sleep hygiene.
