Causes, incidence, and risk factors
There are many possible causes of IBS. For example, there may be a problem with muscles in the intestine, or the intestine may be more sensitive to stretching or movement. There is no problem with the structure of the intestine.
It is not clear why patients develop IBS, but in some instances, it occurs after an intestinal infection. This is called postinfectious IBS. There may also be other triggers.
Stress can worsen IBS. The colon is connected to the brain through nerves of the autonomic nervous system. These nerves become more active during times of stress, and can cause th...
There are many people who confuse Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS). In actuality, they are very different. IBS is a functional disorder of the intestines, in which structurally, there is no pathology. The intestines in IBD however, are inflamed or ulcerated. Ulcerative Colitis and Crohn's Disease are types of IBD. Spastic colon is another term that is used interchangeably with IBS. The diseases are usually easily differentiated by history. At times laboratory studies, as well as imaging studies with barium ( small bowel series and barium enema ) is helpful. Finally, colonoscopy with biopsy can be used. Patients with IBS typically have abdominal pain, with diarrhea and/or constipation. The pain is usually crampy in nature and relieved with a bowel movement. The pain should not awake one from sleep, and is not associated with weight loss or bleeding. When IBS patients have abdominal pain and diarrhea, the symptoms can frequently...
<p><strong>What Is Irritable Bowel Syndrome?</strong></p>
<p>Irritable bowel syndrome (IBS) is the most common gastrointestinal disorder in the United States. It is characterized by intermittent periods of constipation or diarrhea and often pain or bloating. After partly digested food leaves the stomach, it is moved through the small and then the large intestine by regular contractions (peristaltic motility) of the muscles in the intestinal wall. In IBS, these muscles may go into spasm and move residues either too quickly (causing diarrhea) or too slowly (causing constipation). IBS should not be confused with the more serious inflammatory bowel diseases.</p>
<p>There is no cure for IBS; treatment focuses on relief of symptoms, which can often be accomplished with a combination of diet and stress management. Medications are also sometimes helpful. IBS is more common in women than men, and symptoms may worsen in relation to menses.</p>
