I have a mare who often presented with colic symptoms, often overnight and only seen on camera but she’s fine in the morning. Banamine often resolved, but on a couple of occasions had to have vet out to at least run fluids. I suspected gas. I did also observe some other things-- somedays there was enough poop but in smaller or larger piles than normal. This all came to a peak in January, where we thought we were treating a colic caught too early to show anything but elevated HR. Ended up inpatient on a Monday morning, oiled, fluids etc, On Tuesday she passed all the poop but would not eat. Stayed painful in her gut. By Wednesday fever spiked, very painful and diarreah. We had full blown colitis. Vet and I agree that what we thought was mild little colic-like episodes was actually her fighting a battle with colitis-- she’d get painful, but it would pass. She’d be better, then not. If I saw this again, I’d start with good gut support. (she’s currently on Platinum GI, after much research). No NSAIDS or antibiotics for about six months.
Just something to think about.
