You smoke sometimes.
Why it’s key: Taking birth-control pills or using hormone replacements while smoking, even a little bit, ups your risk of developing blood clots and having a stroke. ‘If you take thyroid medication, smoking breaks down the drug faster, so you may be getting a lower dose than you need,’ notes Dr Donnica Moore. And, of course, smoking increases your risk of type-2 diabetes, heart disease, various cancers and other conditions. If your doctor doesn’t know, she can’t screen you appropriately for those, says Goldberg. How to spit it out: If you quit, which is the best thing to do, you can lead with that good news before sharing your history! Otherwise, woman up and ask about smokingcessation methods.
