Crohn's DisEase A basic crash course
Crohn’s disease is an inflammatory disease that affects the end of the small intestine and the beginning of the large intestine, but can affect anywhere in the digestive system. Inflammation means red or raw. Crohn’s disease affects the digestive system in a way that it attacks the healthy cells so that the system can't work.

This is a microscopic view of the Crohn's virus

Some symptoms of Crohn's are: fatigue (being over tired, sometimes slowed), diarrhea, weight loss and anemia (not a sufficient amount of healthy red blood cells). In some cases of Crohn's people will experience abdominal pain, abdominal pain is cramping or tenderness that can be mild or severe.

The difference between the healthy and not healthy is remarkable
Inflammatory Bowel Disease also known as Crohn's has no known cause. Nevertheless there are still hypothesis on how one can get Crohn's, researchers believe that Crohn's is caused by the environment, genes or an autoimmune reaction. Autoimmune is when the immune system attacks healthy cells.

In conclusion Crohn's is a rare but deadly disease that could end your digestive system, Crohn's will cut off the flow of waste from the small intestine to the large intestine. Even if you lost that tiny connection between the small and large intestine your whole system would not function, so this proves that all of the organs need to work in perfect harmony or the whole system won't work quite the same.
