Not being a doctor, I can't say for certain. But, here's a semi-wild guess. Cipro is an antibotic; apparently it inhibits bacteria replication. (http://en.wikipedia.org/wiki/Ciprofloxacin) So, my guess would be that your problem, at the moment, is an overabundance of 'bad' bacteria in your gut.
So, you might try something to get your bacteria back in balance; some sort of probiotic. Apparently VSL #3 does wonders for inducing remission in UC patients -- 70-80% remission rates in some studies. Other people here might be able to suggest other probiotics that work for them.
