Kiny, would it be better if I put it this way do you think?
In this scenario, the immune system would react abnormally and mistake alien bacteria for invaders and attack them. White blood cells and pus would accumulate in the lining of the intestines, producing chronic inflammation, ulcerations and bowel injury. When describing Crohn’s most people say it is an auto-immune disease because our own immune system seems to be causing it.
The most common theory is that the immune system overreacts - or underreacts depending on the theory – in the GI tract which means that our body is in short destroying itself.
Another theory concocted by scientists (who put them in charge anyway? They aren’t doctors) is that Crohn’s is a genetic predisposition. It’s like saying you were ‘meant’ to have Crohn’s.
Bearing in mind that people who do not do much research on crohn's are the target audience.
