People may already know this, but just in case some don't I want you to know that you have to declare that you are taking WLI.
I am going to Spain in 4 weeks time so decided to update my annual travel insurance to cover the WLI. I do already have pre existing health conditions, but these have already been declared. They want an extra £109 just to update because I am using WLI. I asked whether the increase is due to the weight loss injections, and they said yes.
I have now cancelled that policy and gone for a single trip one that has cost £33, still with all the same medical conditions., so considerably cheaper.
