How can I include foreign health insurance premiums and medical and dental expenses abroad as costs in my income tax return ? ( Tax deductions). NOTE: I live in the USA

For better understanding, I live and pay health insurance in the US. However, the premiums are ridiculously high and out of pocket and deductibles non-sense. By paying medical and dental attention abroad is wise saving than paying domestic.

I need to include all of the foreign costs in my tax return but can't find this specific situation in the IRS guides.
