Hi All. I am new to this website, but i have not been diagnosed with IBS but i believe i have it. I have mentioned it to my doctor but she just dismissed me. I was wondering if you guys could help me... the symptoms list on this site consist with what i have. I have diarrhea, constipation, severe gas (which is very painful). When i get nervous the diarrhea gets worse. I never ate unhealthy but i have changed my diet to add in more vegetables & more exercise - i am not overweight or anything. I just dont wont to get bowel cancer or anything. I know if i continue reading through the website that i will find out more information but any help you an tell me on how to control my system would be great. It affects my life, is there a cure? How have you guys been coping with IBS?
