I have my travel insurance in place for a holiday in September. I saw my GP yesterday about some stomach issues I'd been having and he's asked me to provide a stool sample, and if it's positive I go for a colonoscopy, if negative he will refer for another test. I will need to declare this to my insurer, won't I? When I took out the insurance there were no issues, apart from declaring that I take asthma medication. Even though I have no results to declare to them, do I bring it to their attention now, or wait to see what happens?
