Smoking and the Gut
So, what does the research actually say about smoking and bowel movements?
You may wonder if smoking cigarettes has any effect on your bowels, like coffee does. After all, isn’t nicotine a stimulant, too?
But the research on the intersection between smoking and diarrhea is mixed.
Few direct links have been found between smoking a cigarette and having a bowel movement. But a lot of research has been done on the effects of smoking on inflammatory bowel disease (IBD), of which diarrhea is a major symptom.
The first thing to know is that smoking may make diarrhea symptoms of IBD — like Crohn’s disease, a type of IBD — more severe.
A 2018 review of research on smoking, Crohn’s disease, and ulcerative colitis (another type of IBD) concluded that nicotine therapy may help control the symptoms of ulcerative colitis for former smokers — but it’s only temporary. There’s no long-term benefit. There have also been reports that smoking can actually increase ulcerative colitis activity.
On top of that, researchers note smoking can raise your risk for developing Crohn’s disease. It can also make the symptoms much worse due to inflammation in the intestines.
Moreover, smoking may also raise your risk for bacterial infections that affect the intestines and cause diarrhea.
