I have this exact same problem. I have put on about 8 kilos in a matter of 2 months and have been diagnosed with IBS. I am 22 and have always been fit & have had a tiny stomach. I read someones reply about a diet... I think this could be the culprit for me also so I am going to try a liver cleanse. I also have spinal lubsaxations and the pain arrived at the same time as the IBS. But I have been going to see the chiro twice a week for over a month now & I still look 9 months pregnant. Please let me know your progress, my doctor has the same attitude! males!
