Welcome to the MedHelp forum!
Generally pale colored stools with gas and gut problems are seen in a problem of the biliary tract which may include gall stones, bile duct stricture, biliary cirrhosis, sclerosing cholangitis, Cysts of the bile ducts and cancer or benign tumors. Viral or alcoholic hepatitis and side effect of certain medications are the other causes. You may need to consult a hepatic specialist and get this investigated by conducting certain tests like CT scan, liver function tests and other invasive tests like magnetic resonance cholangiopancreatography (MRCP) or endoscopic retrograde cholangiopancreatography (ERCP).
Since I cannot examine you and know other related conditions you may be having, nor is a detailed history possible on net, I have listed the various possibilities that should be looked into. Please consult your PCP for primary examination followed by proper referral.
^^ agree with doc, likely biliary or liver.
Get thee to a doctor ASAP!
