Im 27. can a nodule on your thyroid cause hypothyroidism, hyperthyroidism or either? thank you very much

Either: Your doctor can evaluate you and discuss the referral and treatment options with you

Yes and no.: Yes. "Functional" nodules producing thyroid hormone independent of the feedback system involving thyroid stimulating hormone from your pituitary, can cause hyperthyroidism. Typically you do not develop hypothyroidism due to a single nodule. A nodule may also represent a benign or cancerous growth. Typically thyroid nodules are biopsied and various imaging helps categorize the type. Follow up w/ MD
