Smoking
Those people who smoke on a regular basis tend to be at a higher risk of developing Crohn’s diseases than non-smokers. This is mainly caused by the interaction between harmful chemicals in tobaccos and your immune system, as well as the combination of environmental and genetic factors. More specifically, nicotine-containing products might reduce natural defenses of the intestine and lower blood flow, thus resulting in inflammation. If you still smoke when suffering from this health issue, it might increase the frequency of symptom flare-ups and lead to more severe complications. [3]
