I'm not going to go into details, people, don't worry. But many commenters mentioned having tummy problems often amped by anxiety, and I've had really bad tummy problems for the past several years. Two years ago, I got a colonoscopy and we never quite solved them (but at least I know I don't have Crohn's or celiac disease or colon cancer, at least I didn't two years ago).
Around the time I told my primary care doctor about The Lump (cue DJ Nibbles!), I told her about my tummy problems and she sent me to another gastro doc. The man was wearing a full-on, two-piece, blue-and-white pinstriped seersucker suit. With a bright blue tie. He reminded me of Bert Cooper on Mad Men.
His suit looked like this, only imagine it on a man of about 50 with little round glasses.
The suit was so distracting I nearly couldn't describe my symptoms.
So as I told him, yes, this problem is worst in the morning and it happens right after I eat anything and yes, it's really interfering with my life. He listened and started spouting something I totally didn't understand about bile malabsorption, which is a totally nonthreatening and mostly annoying problem that happens when some bile doesn't get absorbed in the small intestine (natch) and goes shooting into the large intestine, where it is the equivalent of Mentos in Diet Coke.
Guess how they treat it? CHOLESTEROL PILLS! Of course!
Don't ask me. SCIENCE.
So I have these four huge horse pills that I take each day, and I can't take them at the same time as my other meds because of ABSORPTION, so now I have to go buy a BIGGER daily pill pack thing because I swear I can never remember if I took the blasted things or not and I don't want to be the writer who dies from cholesterol pill overdose. I haven't even published my damn novel yet.
But ... so far it's working. It's not a perfect solve yet, but I just went jogging without fear. And that, my friends, is worth seersucker any day. So if you're having chronic tummy problems, don't give up. It might be as simple as ABSORPTION.
