Clinical Information
  • A common syndrome manifested by symptoms of bloating, abdominal cramping, constipation, and/or diarrhea. In most patients the symptoms are not severe and they can be controlled with diet, stress, and lifestyle management. A small percentage of individuals may experience severe symptoms. The cause is unknown.
  • A disorder of the intestines commonly marked by abdominal pain, bloating, and changes in a person's bowel habits. This may include diarrhea or constipation, or both, with one occurring after the other.
  • A disorder with chronic or recurrent colonic symptoms without a clearcut etiology. This condition is characterized by chronic or recurrent abdominal pain, bloating, mucus in feces, and an erratic disturbance of defecation.
  • Chronic noninflammatory disease characterized by abdominal pain, altered bowel habits consisting of diarrhea or constipation or both, and no detectable pathologic change; a variant form is characterized by painless diarrhea; it is a common disorder with a psychophysiologic basis; called also spastic or irritable colon.
  • Functional disorder of the colon that is generally psychosomatic.
  • Irritable bowel syndrome (ibs) is a problem that affects the large intestine. It can cause abdominal cramping, bloating and a change in bowel habits. Some people with the disorder have constipation. Some have diarrhea. Some go back and forth between constipation and diarrhea. Although ibs can cause a great deal of discomfort, it does not harm the intestines. Ibs is a common disorder and happens more often in women than men. No one knows the exact cause of ibs. There is no specific test for ibs. However, your doctor may run tests to be sure you don't have other diseases. These tests may include stool sampling tests, blood tests and x-rays. Your doctor may also do a test called a sigmoidoscopy or colonoscopy. Most people diagnosed with ibs can control their symptoms with diet, stress management and medicine.
