Final answer:
True, IBS is a functional GI disorder with symptoms including chronic or recurrent diarrhea, constipation, and/or abdominal bloating. It is different from IBD, which involves the immune system attacking the intestines.
Step-by-step explanation:
Irritable bowel syndrome (IBS) is indeed a functional gastrointestinal (GI) disorder, characterized by symptoms of chronic or recurrent diarrhea, constipation, and/or abdominal bloating. This is a true statement. IBS differs from Inflammatory Bowel Disease (IBD), such as Crohn's disease or ulcerative colitis, which are more severe, chronic conditions where the immune system attacks the intestines, often resulting in severe diarrhea, abdominal pain, and can lead to many other complications. Soluble fiber supplements may help alleviate symptoms of IBS by regulating bowel movements and reducing discomfort.
