Crohn’s is a very serious inflammation that harms a person’s bowels. This could start from the mouth, throat, stomach, go down to the gut and anus. But the most common form of this disease affects the lower parts of the small intestine and large intestine. We can see lesions of Crohn more easily when these are located in a visible area of the body.
The effects look like what would happen when we see a person having an allergic reaction.
If a person has an allergy, we can see reddish swollen body parts like the face, skin, and nose. Crohn’s also results in swollen, reddish tissues but are seen mostly in affected bowel parts. But the abnormal lesions can also go deeper into the layers of the bowel walls. These appear on the surface of the walls as “skip lesions.” They alternate in a pattern between healthy areas of the bowels. Crohn’s often involves the small and large (colon) intestines. It can also happen in both. On the inside, these injured tissues may look like shallow, crater-like lesions. Some times these go deeper like sores in an alternating pattern. Unlike an allergy attack, this does not go away quickly but can last for a long time. This can even be for the rest of a patient’s life.
Lesions in the mouth and throat areas can appear like reddish sores or shallow ulcers as well. (It is diagnosed as “lichen planus”). These can be seen through an endoscope, a thin flexible tube with a camera at the end. The doctor can insert this through the mouth and go down into the throat, stomach, and bowels. Images taken by the camera can be viewed on a screen as a video. This makes it easier for the doctor to complete his diagnosis in order to determine the cause of the patient’s suffering.
Because of this injury, the normal functioning of the bowels is affected. Symptoms like diarrhea, loss of appetite, indigestion, and irregular toilet habits will happen. Eventually, other body organs like the lungs and joints can also be affected. The brain and nerves also lose normal function due to a lack of energy and nutrition.
