I have been diagnosed with IBS a little over 10 years ago by a gasterenterologist. They did the colonoscopy and determined that it was IBS (diarrhea only for me), but I have not been back since due to financial hardship. I have been experiencing some pain, bloating, gas, unusual bowel movements for me - constipation, and unusual looking feces. It has at times looked to be long and thin which is quite abnormal. I have been a vegetarian for 18 years but for the last 8 months have been vegan. These symptoms have not come on until about 2 months ago, however. If anything, I am eating a lot more fruits, vegetables and fiber, which should make me more regular and NOT constipated (I do not eat any dairy or eggs - nothing from animals at all). I used to have to take 3-4 Immodim a day before going to work just to function at my job, but recently, I have not been taking any of it and still have trouble going to the bathroom. I am concerned that this may be something serious. I have read everything I can about these symptoms and have seen that it could be a sign of colon or rectal cancer. I am not an alarmist, but am interested to know if I should be seeking medical attention immediately. Thoughts? Thank you. Rebecca
