I know this is somewhat old, but I'll tell my story (the quick version). I was diagnosed with pancreatitis last October. I was having a bad year and going through alcohol binges. During my worst 4-5 week binge, I developed acute pancreatitis and was hospitalized for four days. Over the next couple months, after being released, I couldn't eat any solid foods. Eating caused extreme pain and some days I didn't eat at all. I lost 20 pounds in those couple months.
I feel your guys' pain, and I do have flare-ups occasionally. Luckily, I was able to quit the booze (it was either that or die).
As far as smoking and pancreatitis, after extensive reading on pancreatitis (when something like that happens to me, I try to learn as much as I can) I found numerous evidences (can't produce them right now) that link cigarette smoking to causing complications with pancreatitis (if you've already had it). I believe it's because, when you smoke, the smoke doesn't only go into your lungs, in goes into your stomach as well.
There are also numerous studies that link cigarette smoking to an increased risk of developing diabetes. This has been proven; therefore, smoking definitely has an affect on the pancreas. Here's a link I found from a quick Google search:
Cigarette smoking and diabetes. [Prog Cardiovasc Dis. 2003 Mar-Apr] - PubMed - NCBI
As far as vaping, I highly doubt it, but of course, we can't know for sure. And I kept smoking for many months after my pancreatitis, and even that didn't cause too many flare-ups (that I know of, at least).
Either way, I'm completely off tobacco now. And even though I'm still getting nicotine from vaping, my best guess is that it's all the carcinogens, tar, and chemicals in the tobacco from cigarette smoking that affects the pancreas. Of course, I'm not an expert, and only going by what I've read (which is
a lot).
I hope all of you other pancreatitis survivors are doing well. It's a little known, very serious, and extremely painful condition (I read a study on female pancreatitis survivors--it concluded that the pain is worse than child birth). I know what you are all going through.
Anyway, I just wanted to share my story, and maybe try to help others suffering with this who didn't know that cigarette smoking has an effect on the pancreas.
