Ping gas problem... colon cleaning needed?

This is not a joke, I am being 100 percent serious with this question. I have a really bad problem with farting. After every meal I eat I am ALWAYS bloated and have the constant urge to p gas. I eat very slowly, so it doesn't have anything to do with eating too fast. Does anyone know what this means? It has been like this for about 3 years now and I have a new girlfriend and its embarring always having the urge to fart around her. Would a colon cleaning help??
