I am 17 years old, 53, and 92lb (41.7 kilo). i eat regularly, and have no eating disorders. im as active as i can be, but thats hard due to hip issues. an overactive thyroid runs in the family- could that be whats wrong with me?

maybe/not. This is evaluated with a simple blood test and exam. I don't know that anything is wrong with you with the numbers you cite.

This is worth having a conversation with your pediatrician. S/he can check for the status of your thyroid if that is your primary concern and address the specific worries you have with your body. With the information given, you sound quite healthy.

I don’t believe your thyroid and hip condition are related. Because you are such a young age it’s very possible you have developed biomechanical insufficiency with a possible limb length difference or rotation of the hip causing you to have hip pain. The pain is usually associated with the greater trochanteric bursa or the sacroiliac joint
