My GP diagnosed me with IBS 4 years ago from symptoms alone. Since April this year I have been suffering really badly with the problems I had before like D, heartburn, cramping and symptoms I never had before. I am in the process of having all the tests done and am having a Colonoscopy on Thursday.The reason why I am posting is because of my new symptoms, I vomiting often and have lost 14lbs since April. I am also dizzy and have noticed bruises from nowhere all over my body.I am really worried, I feel shocking. I know that there are many symptoms of IBS but wondered if these most recent ones are common?Could anyone shed some light on this for me? Thanks
