The endoscopy and colonoscopy did not show an exact cause of why my iron is so low. However, the upper endoscopy did show I have a hiatal hernia now, and I've been having some symptoms with it. Those can cause low iron too, but the doc had me go to the lab yesterday to get blood drawn for a full liver panel as I had slightly elevated liver enzymes during my previous bloodwork. He's also testing B12. He took some biopsies during the procedure, so I have to wait on those results. I'm following up with the GI doc in 2.5-3 weeks.

I'm still anxious about everything. I do see the T tomorrow though.
