Coping With Fatigue During Cancer Treatment

Fatigue is one of the most common—and frustrating—side effects of cancer treatment. It’s more than feeling tired; it’s a profound lack of energy that rest alone can’t fix. The good news: there are proven strategies to help.

What Causes Treatment-Related Fatigue?

• Chemotherapy or radiation effects on healthy cells
• Anemia
• Stress or anxiety
• Sleep disruptions
• Changes in appetite or nutritional intake

Ways to Manage Fatigue

• Prioritize rest without oversleeping
• Stay gently active with walking or stretching
• Eat small, balanced meals throughout the day
• Ask for help with daily tasks
• Practice mindfulness or relaxation techniques

If fatigue becomes overwhelming or interrupts daily life, talk with your care team. Sometimes fatigue can indicate anemia or other medical needs that can be treated.
