Difference between IBS and IBD

Irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD) affect the large intestine and can cause abdominal discomfort and diarrhoea. However, IBD is an autoimmune condition, while IBS refers to a collection of chronic symptoms. IBD > causes inflammation of the gastrointestinal (GI) tract (from mouth, through stomach and intestines to anus). > two main types of IBD are ulcerative colitis and Crohn’s disease. [1] Crohn’s disease most commonly affects the small intestine and the start of the large intestine, causing patches of inflammation that damage multiple layers of the gastrointestinal tract. [2] Ulcerative colitis primarily causes continuous areas of inflammation which only affect the innermost layer of the colon wall. > Crohn’s disease is typically more severe than ulcerative colitis but is less common. > IBD typically occurs due to a problem with the immune system. It can run in families. > lifestyle factors, such as smoking, can also increase the risk of developing IBD. IBS > contents move too fast or too slow through the intestines, usually accompanied by abdominal pain. > causes a group of digestive symptoms without any visible signs of damage or inflammation in the GIl tract. > common condition and affects up to 21% of people globally. It is more common in women than in men and is more likely to develop in people under the age of 50. > can cause a great deal of discomfort and severely affect your quality of life. Symptoms can range from mildly annoying to disabling, which negatively impacts a person’s self-image, their social life, and the ability to work or travel. > people with IBS are more likely to have other functional disorders eg. fibromyalgia and chronic fatigue syndrome. > digestive problems and increased gut sensitivity may play a role in IBS. Stressful life events and mental health issues, such as depression and anxiety, may also increase a person’s risk of developing IBS. It is possible that the condition may run in families.
