Irritable Bowel Syndrome (IBS)

What is Irritable Bowel Syndrome?

IBS is quite a common condition and describes a disorder of the gastrointestinal (GI) tract.  IBS specifically affects the lower GI area consisting of the small intestine, large intestine, and colon.

Note IBD (Irritable Bowel Disease) refers to a group of disorders that cause inflammation or destruction of the bowel wall (such as Crohn’s disease or Ulcerative colitis) This can lead to a variety of acute conditions such as sores and narrowing of the intestines. It’s possible to have both IBD and IBS.

Usually, IBS is presented as chronic discomfort and other unspecific symptoms affecting the digestive tract. IBS is strongly related to your lifestyle habits, diet and stress and can be managed to have a normal life.
