hypothyroidism in early age

These are questions for your doctor. It's highly likely that you will be taking medication every day but who knows what treatments will be developed in 10 years, or even one? And will it affect your life after marriage - you do realize that your body has no idea when you get married, right? Unless this is a coy way of asking if you'll still be doing HRT after you lose your virginity - the two are unrelated.

But either way, ask your doctor these questions. You are not bothering your doctor. This is a part of his or her job. And if your doctor makes you feel bad for asking, find another doctor.
