flatulence and bloating

Dear Doctor I'm a 27 years old male and for at least the past 5 years now I've been suffering from chronic flatulence and bloating.The problems started when I was using a lot of proteins,amino acids and creatine.When I started using creatin I immediately noticed that something is wrong with my stomach.I started experiencing hard stool,then diarrhea,than hart stool again,then diarrhea......and in the same time flatulence and bloating.I went to a hospital , the doctor performed colonoscopy(endoscopic biopsy) and said that i have m.crohn. ileitis terminalis.He gave me Salofalk tablets for one year and after one year stool problems disappeared.After that he gave me Mucofalk orange granulat.Now i dont have stool problems but I still have a lot of gases.I´m avoiding food and drinks that makes me gases(milk,soda drinks,cerials,bean,green bean,pasta,brown bread....) but I still have a lot of gases.Can you please help me with some tablets or suggestions.

Best regards

P.S sorry about my English :)
