Not sure if I need to see GP and don't want to waste an appointment if not necessary.
Came back from Latin America 2 weeks ago. Was there for 2 weeks and had no problems but had loose bowels since returning home. Typically I'm 'constipated' as I have slow guy motility & often only empty my bowels 2-3 x week. Since I've been back I started out 5x day but only loose not liquid (but this is clearly far from normal for me). Stools have been liquid at times and now back to loose. Over past two weeks the frequency has slowed to 1-2 x day but still loose and quite smelly stools.
I've had sore throat & fever and also felt quite unwell last week. Writing it down like this I feel I've answered my own question!
