Managing Side Effects
General Nutrition Guidelines During Cancer Treatment
You may have difficulty eating or lose your appetite during cancer treatment. Try eating small, frequent meals instead of three large ones. To improve your appetite, don't drink beverages with your meals.
Fatigue can come and go or stay constant for a while. Fatigue from chemotherapy tends to happen a few days after the treatment, peaks, and then gets better before the next treatment. Fatigue from radiation may not happen right away.
