A relationship between not smoking and ulcerative colitis has been examined in all English reports. This paper evaluates the ulcerative colitis/nonsmoking and the Crohn's disease/smoking association by meta-analysis and against causality criterion for chronic diseases. A review of the literature, meta-analysis of selected studies, and assessment of causality criterion all suggest that not smoking and ulcerative colitis and smoking and Crohn's disease are consistent with a causal relationship… Expand
Inflammatory bowel disease and smoking : A review
TLDR
The historical, clinical, and therapeutic aspects of the association between smoking and inflammatory bowel disease are reviewed. Expand
Role of smoking in inflammatory bowel disease: implications for therapy
TLDR
The role of smoking in inflammatory bowel disease and its implication for therapy is reviewed to offer some insight into the pathogenesis of the two conditions and possibly lead to alternative therapeutic options. Expand
Smoking and inflammatory bowel disease: a meta-analysis.
TLDR
It is confirmed that smoking is an important environmental factor in IBD with differing effects in UC and CD, and the current analysis provides an estimate of the effect of smoking on both these forms of IBD. Expand
Smoking influences the need for surgery in patients with the inflammatory bowel diseases: a systematic review and meta-analysis incorporating disease duration
TLDR
Current smokers with Crohn’s disease are at increasedrisk of surgery, while former smokers with ulcerative colitis have increased risk of colectomy. Expand
The role of cigarettes and nicotine in the onset and treatment of ulcerative colitis.
TLDR
Although the aetiology of ulcerative colitis is unclear, current research using nicotine-based products has produced some interesting clues, together with the possibility of some form of therapeutic treatment based on nicotine administration. Expand
Inflammatory Bowel Disease and Smoking: A Review of Epidemiology, Pathophysiology, and Therapeutic Implications
TLDR
The relationship between smoking behavior and inflammatory bowel disease (IBD) is reviewed, considering epidemiological, pathogenetic, and clinical aspects. Expand
Editorial: The Truth About Cigarette Smoking and the Risk of Inflammatory Bowel Disease
TLDR
It is shown that increasing exposure to smoking is associated with an increased risk of developing Crohn's disease and that the risk of UC is highest in the first 2–5 years after smoking cessation but remains elevated for >20 years. Expand
Breastfeeding and risk of inflammatory bowel disease: a systematic review with meta-analysis.
TLDR
The hypothesis that breastfeeding is associated with lower risks of Crohn disease and ulcerative colitis is supported, because only a few studies were graded to be of high quality. Expand
Smoking in inflammatory bowel diseases: good, bad or ugly?
TLDR
The role of smoking in inflammatory bowel diseases is reviewed, finding that smoking cessation aggravates ulcerative colitis and improves CD, and smoking increases the risk of developing CD and worsens its course, increasing the need for steroids, immunosuppressants and re-operations. Expand
Current concepts The role of cigarettes and nicotine in the onset and treatment of ulcerative colitis
Epidemiological evidence suggests that ulcerative colitis is a disease ofnonsmokers, while Crohn's disease is a disease of smokers. The relative risk of developing ulcerative colitis is not onlyExpand

Nonspecific inflammatory bowel disease and smoking.
TLDR
The association between current smoking and Crohn's disease was even stronger when age at first onset of bowel symptoms was considered as the index date, but the risk for ex-smokers fell below unity. Expand
Smoking in inflammatory bowel disease and the irritable bowel syndrome.
TLDR
Patients with ISS and ulcerative colitis smoked significantly less than those with Crohn's disease and any protective role postulated for smoking in the patho­ genesis of ulceratives colitis should also be considered for 18S. Expand
Smoking habits in patients with inflammatory bowel disease. A case-control study.
TLDR
The hypothesis that smoking may influence the course of inflammatory bowel disease is supported and patients with ulcerative colitis and Crohn's disease should be aware of their smoking habits. Expand
Cigarette smoking and inflammatory bowel disease.
TLDR
Patients with inflammatory bowel disease and matched community controls taken from general practitioner lists were questioned about their smoking habits and there were only small and nonsignificant increases in the risk of Crohn's disease or ulcerative colitis in exsmokers. Expand
Smoking and inflammatory bowel disease. A case control study.
TLDR
A population case controlled study of smoking habits at the time of diagnosis was done in 260 patients with ulcerative colitis and 144 with Crohn's disease, where a non-significantly increased risk was observed and a rebound effect was seen. Expand
Smoking and Crohn's disease.
TLDR
Patients with Crohn's disease were significantly more likely to be smokers than the controls, and the association was stronger for smoking habit before the onset of the disease than for current smoking habit, showing an association between non-smoking and ulcerative colitis. Expand
Smoking and ulcerative colitis.
TLDR
It is suggested that smoking directly or indirectly confers protection against ulcerative colitis and could be explained by confounding by social class. Expand
Smoking habits in patients with inflammatory bowel disease.
The proportion of smokers in this study was significantly lower among patients with ulcerative colitis (13%) than among patients with Crohn's disease (47%), the difference being significant for bothExpand
Chronic inflammatory bowel disease, cigarette smoking, and use of oral contraceptives: findings in a large cohort study of women of childbearing age.
TLDR
Both ulcerative colitis and Crohn's disease were more common among women currently using oral contraceptives than among those not doing so, and this observation provides an important clue to the aetiology of chronic inflammatory bowel disease. Expand
Risk of ulcerative colitis among former and current cigarette smokers.
TLDR
The relative risk of ulcerative colitis among former smokers increased in proportion to the cumulative number of cigarettes smoked before the onset of disease, suggesting a causal relationship between this exposure and disease occurrence. Expand
