Bleeding
It can be pretty scary to look down into the toilet and see blood, especially if there’s a lot of it. Rectal bleeding is a common symptom of Crohn’s disease and the amounts of bright red blood that can appear in the stool are sometimes quite alarming.
This symptom of Crohn’s disease is the cause of many other complications associated with the condition, including lack of nutrients and low red blood cell count leading to iron deficiency and anemia.
Bleeding may occur sporadically or seem to have no rhyme or reason, but its presence signals the effects of inflammation in the gut. Amount and frequency of blood may be related to the ingestion of foods high in fiber, but there are also some who believe that foods with high amounts of sugar and complex carbohydrates can play a role as well.
Eating foods that are not on the normal diet of the individual, such as going out to eat at a restaurant and trying something not commonly eaten, may have an effect on the bowel and thus result in rectal bleeding.
