Our expert says:
Losing weight without dieting plus bleeding is always a red light as cancer often can present with these symptoms. It may be nothing but your doctor is being cautious and it is the right thing to go for a scan and colonscopy (scope) as soon as possible. You may be tired as you may be suffering from anemia due to the bleeding. Bleeding from the colon could be due diverticulitis, a bleeding polyp in the colon, inflammatory diseases of the colon like ulcerative colitis or cancer.
