Hi, I have been passing alot of blood n my stools the last few days with large dark blood clots. It have happened om occasion over the last four months but the amount today frightened me! I have suffered with constipation for three to four years. Had an endoscopy last summer all clear! Since January I have rarely passed a fully formed stool. When I do they are often frothy in texture and stink of metal. Lately I find myself dehydrated and fatigued alot . after passing a stool I am often I m agony or feeling like I am burning and the urge to go remains for some time. I am 30 130pounds and eat healthy as well as daily exercise. Maternal Uncle had bowel cancer and mother has colitis. Have not gone to a doctor because over the last number of years I get fobbed off with the eat health exercise story everytime and leave feeling like I am crazy!
