hi. noted history of endometrial hyperplasia, ovarian cyst and hyperthyroidism. it is best if you consult with a gynecologist and an endocrinologist regarding your concerns. with regards to your endometrial hyperplasia and ovarian cyst, monitoring by doing ultrasonography and a regular follow-up with your gynecologist is best. with regards to your hyperthyroidism, physical examination and clinical evaluation of your endocrinologist is best. a neck ultrasound may also be requested for additional evaluation of your thyroid gland along with thyroid functions tests. management (medical and/or surgical if indications are found) will be directed accordingly. hope this helps. good day!! ~dr.kaye
