Unexplained Weight Loss
People with bowel cancer might experience a change in their appetite, especially a loss of appetite. This would lead to unexpected and sudden weight loss. So, if you are dropping more than 10 pounds or in an extended period without trying, it might be a noticeable sign to inform your healthcare provider. In most cases, it is caused when the tumor consumes more energy in the body and the immune system has to work harder to fight against cancerous cells. Blockages in your colon can also affect normal digestion. Another reason is that some tumors can release substances, which would increase your metabolic rate. This eventually results in an unexplained loss of body weight. [5]
