I Have Over A Number Of Years Suffered From Severe

I have over a number of years suffered from severe and sometime uncontrollable diahorrea, often when I travel overseS this problem seems to get worse, I have just been in Australia for 4 weeks and had severe diahorrea and extreme stomach cramps for most of the time I've been there. I wonder if I can trace it back to a severe bout of sickness an diahorrea I picked up on a trip to Kenya some years ago, as it seems to be dormant tgen reoccurr?
