FWIW I dealt with a similar situation last year. I ended up talking with a life insurance *broker* (not agent), who was more comfortable dealing with 'special cases' -- i.e. people with conditions/medications that are more difficult to underwrite.
She knew right away which companies/underwriters would be best for my conditions and would be most likely to give me a favorable rating.
I was previously given ridiculously high rates from a couple of companies I applied for on my own. However, through her, I was given an amazing rate. Sort of unbelievable, and with Prudential, which is a very healthy large insurer. I then used the very good rating to negotiate with another company I had applied with as a backup, and they changed my rating from a less favorable category to a more favorable one (but not the best possible category). I ended up buying two policies, one larger and one smaller to meet my needs.
I also was extremely strategic in everything I did leading up to the applications and exams, due to high cholesterol, high blood pressure (neither documented in medical records yet), various medications, etc. I answered the questions carefully being I know their technocratic algorithms would flag if I said the wrong thing. i.e. I use nicotine gum periodically but always answered no to nicotine usage. The spirit of what they were getting at is if I was a smoker / chronic high user, and I felt ethically OK saying i was not a user even if it is a bit gray.
I am on carnivore diet so I had to heavily manipulate my dietary pattern for a period of time to get various labs in normal range i.e. BUN and liver enzymes. Tested on my own several times off the record (through
Defy and/or privateMDlabs). Used various cholesterol lowering meds for a short time. Used cialis and an ARB for blood pressure the day prior and day of (all of these meds except cialis gray market so no script). I'm borderline on BP but wanted to be sure it was well within normal, plus those meds make me feel like shit.
