My Dad is currently taking creon to help with digestion of food. Prior to taking Creon, he had gas ,bloating, full feeling after small instake of food . He started taking Creon (approx 1 1/2 weeks) The belching, gas pain and bloating seemed to have worsened. Should he take the Creon before during or after a meal? Will the Creon help relieve the gas, bloating full feeling or does it just help nutrionally digest the food?
