Can anything else cause a flare up?
Significant anecdotal evidence suggests that flares of IBD often occur after increased use of non-steroidal anti-inflammatory drugs (NSAID’s), such as aspirin and ibuprofen. Accordingly, patients should be very careful about taking these medications and be aware that they may cause a flare of their disease. In fact, some physicians who are very experienced in managing IBD feel these drugs should rarely if ever be used by IBD patients.
