Any advice?

(42M) I have for a number of years had stomach issues, reflux, excess gas, cramps and exercise induced cramps. I had a faecal calprotectin test which came back 650+ and follow on FIT test which was negative. That was last August and im still waiting to see a consultant (UK NHS) and I've got another 5 months to wait. I've tried most diet changes, e.g. mainly eating easily digestible foods, using diaoralyte, cutting out dairy. Is there anything else I could be doing to help? I have loose stools most days, go 3/4 times a day. I was feeling exhausted by 5pm most days but I've upped my CV exercise and that seems to have helped a bit. What else could I be doing?
