Post infectious IBS...cancer?! My anxiety is overtaking me...

Hello,

I'm a 41 yo male, healthy (don't smoke, not overweight, exercise regularly) who's suffered from IBS-A for many years.  Had a negative colonoscopy 8 yrs ago.  However over the past few weeks things seem to have worsened and I was wondering if anyone's experienced anything similar.  About two weeks ago I had what I assume was a viral stomach bug (a day of diarrhea, chills and nausea).  This only lasted about a day.  Never had any bloody stool.  Felt okay for a couple days.  But then a few days later had terrible lower abdominal cramps and had the urge to have a BM every 30 minutes or so all morning.  Since then have had pretty much constant crampy abdominal pain (mostly below my belly button but sometimes all over), bloating, some nausea, loss of appetite and even lost a few pounds because I just don't feel like eating.  The diarrhea has resolved, now just having some intermittent hard / soft stools with some mucus.  Also woke up one night in the middle of the night with cramps and had to have a BM and couldn't fall back asleep due to the cramps.  Saw my GI and had normal stool cultures (no c. diff, crypto, giardiasis or bacterial infections) and a normal CBC. i have a colonoscopy scheduled for next week but I'm freaking out about something more serious (i.e. cancer).  My wife thinks a lot of my symptoms are "psychosomatic" as I have a pretty strong history of anxiety.  She thinks a lot of my loss of appetite and resultant weight loss are more because of anxiety and stress.  I know it seems unlikely to develop cancer just 8 years after a normal colonoscopy but my mind likes to go to bad places  Thoughts?  Anyone else have a similar experience with a flare of post infectious IBS?  Thanks!

Sounds like post infectious IBS made worse by anxiety.  Loss of appetite and weight loss can be caused by anxiety and can also occur with IBS especially if you start eating less because of food triggers.

These don't sound like symptoms of cancer.  I'd say if it was cancer the symptoms would not come and go, they'd most likely always be there.  Also I can't see it being cancer if no blood was present.  Just my thoughts but I think you are doing the right thing by seeing a Dr.

Also did the Dr. do bloodwork?  I was always told if one had cancer something would show or be an indication from the bloodwork- at least that is what my doctor told me.
