I wouldn't necessarily regard menopause as a condition however if you are taking prescription HRT then this should be declared if you are asked about prescribed medication.
Just a note of caution to anyone taking out travel/medical insurance - ask your GP practice for a summary of your medical records prior to completing the form.
You may be surprised what you have been labelled with without your knowledge. I had apparently been diagnosed with "hypertension" (I am on medication for LOW blood pressure!), "anxiety and depression", "primary drinking disorder" (I am intolerant to alcohol so never drink at all) and "Bulimia" - the latter during a year that I wasn't even resident in the UK!
If I had ever had the misfortune of having to make an insurance claim, I would have looked like a liar for not disclosing any of these conditions, none of which I have ever suffered from and did not know were on my medical record.
Not a fan of the DM but this article highlights how widespread this issue is
