Until you've been to the doctor to get stuff ruled out it is hard to say.Here are the symptoms that describe IBS (need 2 to call it IBS).Pain or discomfort that is relieved by a bowel movementPain or discomfort that is associated with a change in stool frequencyPain or discomfort that is associated with a change in stool consistancy.-----Many people with IBS will have more than 3 BM's a day or less than 3 a week.Many people with IBS have problems with gas (for most it may be more a problem of being intolerant to normal levels of gas rather than increased amounts of gas).Depending on your age, your symptom profile, and your doctor they may run some tests before making a diagnosis (generally if your younger, or your symptoms are either typical or not on the severe end of the spectrum you will have fewer tests run than if you are older, have atypical symptoms, or have severe pain, constipation, or diarrhea).K.------------------I have no financial, academic, or any other stake in any commercial product mentioned by me.And from the as if IBS isn't enough of a worry file...from New Scientist's Feedback column: photographed on the door of a ladies' loo in the Sequoia National Park in California by reader Liz Masterman: "Please keep door closed to discourage bears from entering."
