Well my doctor dont really care , but the times I have been to hospital they have been quite concerned ( last time the emergency doctor told me she could feel some veins in my stomack that she was not suppose to feel , she said it was cause i was so thin she could feel em ) They have done blood test after blood test and xrays at the hospital but it all comes back clear ( doctor wont refer me to specialist cause she dont believe in IBS and if there is no bleeding she say its nothing serious ) I was over weight before thou but now im underweight ( mind you my new short summer skirts looks brilliant on my new slimmer me LOL )
