Frequently Asked Questions
What is Irritable Bowel Syndrome (IBS)?
Irritable bowel syndrome (IBS) is a disorder characterized by chronic abdominal pain or discomfort and bloating that is typically associated with a change in bowel movements. It affects as many as 20% of the US population. Most can control their symptoms with diet, stress management, and prescribed medications.
What are the Symptoms of IBS?
The main symptoms of IBS are abdominal pain or discomfort and bloating, diarrhea and, or constipation. People with IBS may experience cramps, gassiness or feelings of urgency.
What Causes IBS?
It is not known exactly what causes IBS. Some researchers believe that a dysregulation of the brain-gut axis (the nerves that link the brain and the gut, which control intestinal muscle contractions and other normal gut functions) is one of the likely causes of the symptoms of IBS.
How is IBS Diagnosed?
Only a doctor can diagnose IBS and determine that symptoms are not caused by other disorders such as Crohn's disease or ulcerative colitis. This begins with a complete medical history, including a description of symptoms and a physical examination.
To rule out other diseases, a doctor may order diagnostic tests. These may include stool sample testing and x-rays. And for the first time, there is now a blood test for IBS, PROMETHEUS® IBS Diagnostic that may assist your doctor in diagnosing IBS. To learn more, visit the IBS Diagnostic section of this website.
A doctor may perform a sigmoidoscopy, or colonoscopy, to view the inside of the colon. A small, flexible tube with a camera on the end is inserted through the anus and into the colon. Images of the colon are then transferred onto a screen for the doctor to view.
What is the Treatment for IBS?
There is no known cure for IBS, but there are many options for treating symptoms. Stress reduction and changes in diet may help. Your doctor can create a treatment plan that works for you.
How Does Stress Affect IBS?
Stress can trigger IBS symptoms or make them worse. This is because the colon has many nerves that connect it to the brain. It is controlled, in part, by the nervous system. During times of stress, the nerves controlling normal contractions of the colon can cause spasms and discomfort.
For people with IBS, sometimes the slightest tension can cause the colon to be overly responsive. To help reduce stress, try these:
- Seek professional counseling or support from friends
- Get regular exercise
- Improve sleep habits
- Try relaxation therapies
Is IBS Linked to Other Health Problems?
There is no evidence that IBS leads to other diseases, such as inflammatory bowel diseases (Crohn's disease or ulcerative colitis).
