Irritable Bowel Syndrome. Irritable bowel syndrome is a disorder characterized most commonly by cramping, abdominal pain, bloating, constipation, and diarrhea. IBS causes a great deal of discomfort and distress, but it does not permanently harm the intestines and does not lead to a serious disease, such as cancer. Most people can control their symptoms with diet, stress management, and prescribed medications. For some people, however, IBS can be disabling.
Setting aside the serious disease risks of smoking, for just plain old IBS the effects of tobacco can be immediate and downright violent. Tobacco irritates the lining of the intestines, which can cause diarrhea, intestinal cramping, pain, bloating, and gas. Nicotine can cause nausea and stomach cramps. Smoking also decreases the efficiency of food digestion and metabolism, which can cause altered bowel movements (already a problem for people with IBS) and bloating. Nicotine withdrawal can cause both constipation and diarrhea.
