From your question, you seem to be in doubt. A CT may well be called for here, but keep in mind that most of the folks on this board (including me) have experience with GI “challenges.” Many of us have had uncounted CTs. But our risk-profile differs from that of healthy persons. Any downsides to scans are immaterial to most of us.
Thus, all I’d add is that if you’re a healthy person with no known GI disease, I’d consider all the facts and try to decide without reference to emotion or any psychological factors (to the extent that’s possible
) what the best course is. You say you were “offered” a CT. Was it *recommended*? What does your GI (or PCP) think/say? You know your own psychological makeup—are you a worrier about health, or otherwise? Are these (relatively common and often benign (but not always)) symptoms new, persistent, significant? Are they stable, resolving, or getting worse? That sort of thing.
I’d consider those and any other relevant factors, then decide. Either course may be reasonable based on the *totality* of the circumstances, including the above and more. Once you make a well considered call, go forward with confidence. And good luck!
