2) Fatigue and Weakness
It is easy to confuse fatigue with just being tired. Between personal obligations and work, anybody can feel run down at times. It could be fatigue if it doesn’t go away after properly resting. However, fatigue and weakness could also be due to other health conditions like diabetes, cardiac disease, and anemia.
Chronic fatigue in colon cancer can develop as a result of depleting energy sources, loss of muscle mass and internal blood loss from the disease itself. In the absence of nutrients and energy, the body cells shift their metabolism from glucose to ketones and tend to work harder to strive for existence. This creates an acidic environment in the body. Secretion of metabolic waste products and other associated symptoms like alternative bowel habits can add fuel to the fire and increase the feeling of weakness and fatigue.
