For the past 2 months my stools have been on the thinner side; not "pencil thin", but about the diameter of my middle or index finger. They are sometimes long, sometimes broken into smaller pieces, and I would say on the softer side. I usually take on average about 3 of these stools per day. I am not straining to pass them, and for the most part I feel completely evacuated. I went to a GI doctor about 4 weeks ago and was diagnosed with GERD and possible IBS, though not definitive on that one. I do not see any visible blood (which apparently doesn't mean anything), and I have no other symptoms, no pain, no fatigue, no weight loss, or anything like that. The GI Doctor did a complete blood work up and said everything looked fine. I am just getting myself so worked up, and have such horrible anxiety from searching on the internet for hours...I'm actually making myself feel sick inside over it, because of course, when I do a search for thin stools, Colon Cancer is the very first thing that pops up. I should state that I did recently stop taking Omeprazole (OTC Prilosec) and started on Prevacid...all about a month or so ago. My diet hasn't really changed, other than maybe adding a little bit more vegetables to my daily intake...but not enough that I would think it could cause a difference in my stool size. Please, if anyone could ease my mind...I'm having terrible anxiety over this. Thank you in advance.
