Fatigue is one of the most common and most underestimated effects of glioma and its treatment. It's not ordinary tiredness, and it's not something to simply "push through." Understanding it helps you manage it without blaming yourself.
How it's different Cancer-related fatigue is a deep, persistent exhaustion that isn't fully relieved by rest or sleep. It can be physical, mental, or both, and it can make even small tasks feel overwhelming. It often doesn't match your activity level — you can feel drained without having done much.
Why it happens Multiple factors usually combine:
- The tumor and brain involvement itself
- Treatments — radiation (fatigue often builds over a course), chemotherapy, and surgery recovery
- Medications — anti-seizure drugs, steroids (which can also disrupt sleep), and others
- Anemia (low red blood cells) from treatment
- Poor sleep, anxiety, depression, and the sheer emotional load of illness
- Reduced activity, which paradoxically worsens fatigue over time
What helps The evidence points to several strategies, often combined:
- Gentle, regular physical activity. Counterintuitively, light exercise (like walking) is one of the most effective things for cancer-related fatigue, when done within your limits and with your team's okay.
- Energy management ("pacing"). Prioritize what matters, break tasks into smaller pieces, rest before you're depleted, and plan demanding activities for your better times of day.
- Treat reversible causes. Address anemia, sleep problems, thyroid issues, pain, and mood — all of which your team can evaluate.
- Sleep hygiene and managing steroid-related sleep disruption (timing doses earlier when possible, as advised).
- Nutrition and hydration, and accepting help with demanding tasks.
Be realistic and self-compassionate Fatigue can be frustrating, especially when you look well but feel exhausted, and others may not understand. It's a genuine physical symptom, not weakness. Tell your team how it's affecting you — they can look for treatable causes and connect you with support.
