Sometimes irritable bowel syndrome is referred to as spastic colon, mucous colitis, spastic colitis, nervous stomach, or irritable colon.
Irritable bowel syndrome, or IBS, is generally classified as a "functional" disorder. This refers to a "disorder of functioning" where the body's normal activities in terms of the movement of the intestines, the sensitivity of the nerves of the intestines, or the way in which the brain controls some of these functions is impaired. However, there are no structural abnormalities that can be seen by endoscopy, x-ray, or blood tests. Thus it is identified by the characteristics of the symptoms and infrequently, when needed, limited tests.
"My symptoms started when I was about 19 years old – cramping and diarrhea or bloating and constipation. There were days I'd be in the bathroom 8 times or more. It wasn't until years later that I discovered I had irritable bowel syndrome, or IBS, and that I could do something about it."
Irritable bowel syndrome is understood as disorder with many aspects. In people with IBS, symptoms result from what appears to be a disturbance in the interaction between the gut or intestines, the brain, and the autonomic nervous system that alters regulation of bowel motility (motor function) or sensory function.
Irritable bowel syndrome is characterized by a group of symptoms in which abdominal pain or discomfort is associated with a change in bowel pattern, such as loose or more frequent bowel movements or diarrhea, and/or hard or less frequent bowel movements or constipation.
Treatment options are available to manage IBS – whether symptoms are mild, moderate, or severe.
