Hello Christina, welcome to Susan's!
I can understand your hesitation to bring this up with your primary doctor. For years I had postponed the most basic inquiries, didn't take time to plan my future in detail, much less bring it up to others. About 20 years ago my doctor stopped what he was doing, got serious and asked: how much alcohol do you drink on average? I was startled by his question because we hadn't discussed that. In hindsight, he could probably smell it in my skin pores - I was consuming far more alcohol than my body could handle, I quit drinking a few years later (2003). But when he asked that question I was very embarrassed - I said yeah every couple days but not too much. My answer was not accurate and it could have killed me.
Your situation is (hopefully) different, but I brought up an example from my past to help explain my answer. The medical field in most countries operate under strict privacy laws to encourage open communications between patient and doctor. Your doctor needs accurate information to provide an accurate answer. As a professional they should be objective and work within their area of expertise. If your doctor taps into their knowledge to come up with a good solution, or can't find and answer and provides a referral, what do you have to lose? I cannot imagine your doctor freaking out - they see a lot in their line of work. If they start asking questions about lifestyle beyond objective medical requirements, or lecturing you - difficult to imagine - at that point I'd find a different doctor. I bet you'll be fine. Here's your chance to find out.
All the best,
Kendra
