Hi, im a 20yr female and for roughly the last 4yrs ive had constant changes in bowel movements and most of the time get diaohrea. I get cramping, bloating and wind. I have have been tested for IBS, celiacs and they tested my iron, ive had a blood test and stool sample and everything came back normal. They firstly put me on fibre tablets and they seemed to make things worse. They gave me medication for gardia (which worked for a couple of weeks), and than put me colese tablets which dont seem to work?? I'm booked in for a colonoscopy but its not until July. I'm really quite worried. It really affects my living as i dont feel comfortable leaving the house?? Can you please help maybe any further information as to what it may be??? I'm also been tested for endometriosos as i get bad discharge, could this be anyway related?? Thanks
