@naturegirl5 Thank you so much for your answer. My friend was 37 when her symptoms appeared, a virgin, overweight (not because of eating habits but after treatment for insomnia and anxiety with olanzapine that had caused many health problems such as hyperglycemia, high cholesterol, blood pressure issues and the list goes on), she did not have PCOS, she was not going through menopause, not even perimenopause. Her first period was around the age of 13. She never had any problems with her period until the age of 37, when her weight was 80 kg, after having weighed 45 kg her entire adult life at a height of 160 cm. Her doctor tried to find a possible explanation for her illness but it is true that this caused a lot of stress. She managed to find a study published in August 2022 that shows a possible link between antipsychotics, olanzapine included, and endometrial cancer. And that caused even more stress because her weight and health issues appeared after treatment with olanzapine that she is now trying to let go of, which is extremely difficult after many years of treatment. She started taking olanzapine at the age of 31 and at 37 she was obese and with cancer. This is what caused her distress. Thank you again for your answer.
