Chronic fatigue
Most patients with cancer experience chronic fatigue as a part of a very complex wasting syndrome originated by the chemical reactions and structural changes caused by the tumor. Cancer is composed of a fast-growing tissue that needs additional energy to survive. It takes up extra nutrients from the blood and deprives the rest of the body of the energy we need for our day-to-day activities. Patients with colon cancer are often severely undernourished, not because of their food choices but because cancer cells snatch too many nutrients from the bloodstream. That’s why people with colon cancer often experience low energy levels and chronic fatigue.
