Thank you
@BeADocToGoTo1, I have Mg deficiency and I supplement it therefore (a lot), but I don't get the levels to where they should be. Wouldn't that speak against EPI being the cause of the deficiency?
I find this thread interesting, because at the very beginning I developed problems with blood sugar in the sense that after eating the glucose levels were lower than before, which brought problems with it, obviously. This was also shown via a glucose tolerance test. This resolved after some time, and then by chance very high lipase and amylase levels were found, but a MRI (weeks later, when the levels were nearly normal again) showed nothing. During that time the stool was "uncomfortable"
several times pancreatic elastase in the stool was lowish (but some months ago it was normal - can this be an error by the lab, or is elastase higher in the morning and lower in the evening?), and there's nothing more normal for me than to have undigested food in the stool and a high stool frequency, plus severe nausea and heartburn if I eat "too much", so most times I only eat small portions. But I have problems with gaining/holding weight, not underweight.
I tried some digestive enzymes in the past, but never Kreon, and they didn't help. So I thought all these results are irrelevant, the pancreas is fine and it's the gallbladder or whatever (which made problems in the past, too).
So after reading this thread and realizing Kreon is prescription-free here, I thought to give it a try. And indeed, yesterday was the first time since years without nausea and heartburn after eating.
I only had minor heartburn which could be the gallbladder after all. And my sleep wasn't affected.
I speculate about a connection to a calcium channel that could be dysfunctional in me (due to a mutation; I am trying to find a lab that can test this channel, but it's not easy), called Inositol 1,4,5-Trisphosphate receptor (IP3R; in my case, the IP3R type 3 is affected). IP3R3 is expressed in every cell, but, amongst others, it's the predominant isoform in pancreatic acinar cells and cholangiocytes, and it was connected to pancreatitis, cholangiocitis, type 1 diabetes and liver diseases.
