No, she has not done any biopsy yet. We were only told it might be endometrial hyperplasia since she has thickened endometrium.
She was diagnosed with PCOS after an ultrasound when she was 16 years old (she is 27 now). With PCOS, her main concern is the irregular and/or heavy menstrual bleeding and the fact that she has trouble losing weight due to insulin resistance. For treatment she has been taking hormone medicines (Ovral G and Ovral L) and medicines to stop the heavy bleeding (and sometimes medicines to induce menstruation when she doesn’t get her period).
I should mention that she has not always been consistent in taking her medications mostly due to frustration at the fact that no doctor she has seen so far has been able to help her treat it.
