I Have Had Two Coonoscopies In The Past 6 Years.

I have had two coonoscopies in the past 6 years. I took out gluten from my diet because one blood test said i sm wheat sensitive... It feel really bad when i eat it and i get reeeaally fatigued.
I have been having issues since 2010 when i got back from Honduras. I got sudden IBS symptoms. Do you think there might be parasites hiding in me? No doctors can give me answers and i am starting to burp and pass gas from both ends now once in a while. I got asthma which i never had before.... And i never had ab pain through this before but my abs/stomach feel sore these days. Chrons and Colitis are ruled out but i have inflammation in my gut. Can you help me????
