Serious Warning Signs Of Bowel Cancer

Extreme And Persistent Fatigue

Cancer occurs when a mutation in the DNA of a cell causes it to grow and multiply out of control. Any cancerous cells in the body can become extremely invasive to the organs as they continue to grow and spread. Bowel cancer is a particularly aggressive type of cancer where the cancerous cells compromise the bowel and can spread to the small intestine and other organs. When cancerous cells invade the small intestine and destroy the lining, the intestine can no longer absorb nutrients like glucose properly. Without enough glucose, the cells around the body are unable to carry out their processes to produce energy or ATP. Additionally, cancerous cells themselves use up the supply of oxygen, glucose, and other nutrients to carry out their malicious processes, leaving nothing left for healthy cells. This shortage of glucose and cellular energy triggers a mechanism in the body where any energy produced is allocated to the tissues that are the most critical for survival, like the heart and lungs. It is this general scarcity and reallocation of cellular energy that makes a bowel cancer patient feel extreme and persistent fatigue.
