Can't defecate: Stool becomes hard and dry; it's difficult for the colon to move it along, and difficult (and painful) for the hard stool to pass through the anal canal. Lack of water in diet can contribute; chronic use of opiate pain medscan too. Rarely people can have motility disorders of the intestines that contribute to fecal impaction. In extreme cases hard stool can wear through the intestinal wall. ...Read more
Not at ALL: It is not reliable at all. If it is positive, that tells us something needs to be checked. If it is negative, doesn't mean anything. It has a very high false negative rate - meaning, even if something is there, it doesn't detect it. ...Read more

Maybe: The fecal occult blood test can be quite sensitive and may show blood in the stool from minor gastritis or esophagitis that is not significant. But, it could also be due to a large polyp or tumor so colonoscopy is always indicated when the fecal occult blood test is positive. Your primary doctor should be arranging this in the near future. ...Read more
In the lab: Great question. A great way to screen for intestinal cancer as cancers cause small amounts of bleeding, which is then passed in the feces. A less sensitive chemical method and more accurate immuno method can be used. Not all cancers will leak blood, blood in feces is not always cancer and other substances can have false results. Ask your doc about colonoscopy if >50 or family history of cancer. ...Read moreSee 1 more doctor answer

Colon cancer age 30?? RUQ pain, fecal occult test negative- CT- Normal- (GI tract WNL no obstruction or perforation) should I get colonoscopy for pain
Probably: Colon cancer is unlikely in your age group, but other GI and colon diseases can also cause such symptoms. Have you had your gallbladder evaluated? Remember, colon cancer has minimal symptoms and CT is NOT a great test for it. In sum though low yield I would likely recommend colonoscopy to you based on what I've read. ...Read more
