Fatigue is one of the most common symptoms experienced by cancer patients. Cancer-related fatigue is more difficult to manage than fatigue felt occasionally by those who do not have cancer. Managing fatigue is an essential part of your health care. Be sure to speak with a healthcare professional if you are experiencing fatigue.
Why does fatigue occur?
Cancer-related fatigue primarily occurs because the body requires additional energy to repair tissue damaged by cancer treatment. Other side effects of cancer treatment such as pain or anemia can cause or make fatigue worse, as well as certain medications, stress, other medical conditions, changes in sleep, and decreased exercise. Your age, general health, activity level prior to starting treatment, and treatment type can also play a role in how fatigue may affect you.
How do I manage fatigue?
Fatigue can have a serious impact on quality of life and make it difficult to prepare and eat healthy nourishing meals. The body needs nutrients like protein, carbohydrates, fats, vitamins, minerals, and water to function. Improper nutrition can make your symptoms worse.
The following tips can help you manage your fatigue:
While rest is important, too much rest can make you feel more tired so stay as active as possible.
- Try going for a daily walk.
- Talk to your healthcare team before beginning any exercise program.
Go no longer than 4-5 hours without eating throughout the day.
- Try to eat a balanced breakfast every day.
- Try to eat small meals and snacks rather than large meals.
Eat foods that provide sustainable energy; avoid foods that do not.
