I'm not sure on whether you can have too many enzymes or not. That seems to be a general thing across the UK, that you have too get your enzymes exactly right, as too little or too many can be bad. At my old childrens hospitals, they are on the side of too many enzymes is bad. However my current hospital isn't. Infact they say, if you haven't eaten all day, then you should have 1 or 2 creon capsules every 4 hours, to digest built up mucous and stuff.
I've never heard anyone other my dieticians say this though, and it seems really weird.
In my experiance though, from when I was taking no enzymes whatsoever. I was still getting bad blockages and for a few years I had a constant daily dose of 30mls of Lactulose. I was removed from that when my dentist complained. I still get the same kind of blockages now, and about
the same amount, even though I now I take Creon 10,000 religiously.
This could just be me though, and you problems could well be creon related even though mine aren't.
Do you drink plenty of water during the day? That is one of the things the creon packets says. If you're on them you should be drinking plenty of water.
Another thing, is maybe protein. Maybe you aren't eating enough protein for the Creon digesting them. Creon does also digest protein and other stuff aswell as fat. That's just a guess though obviously, as not enough protein tends to be a problem for vegetarians I think.
Maybe also a low dose gentle laxative like lactulose taken daily might help? Again you'd have to drink a lot of water alongside it (and brush your teeth thoroughly each time you have a dose).
Hope some of this helps.
