I have been dx with Fibromyalgia and have been told that IBS goes along with it. I have all the sx\'s of IBS and recently underwent a battery of GI tests which were negative. I have dry skin, thinning hair and have suffered terribly through the years with PMS so, I wondering if I have a \"fat\" metabolism problem. Of interest, I have a child with CF and like other CF patients my child cannot absorb fat. I\'m also very thin but haven\'t been dieting. Where does one find out if one has this fat metabolism problem?
