Hello,
Thanks for posting your query.
A polyp is a benign tumour on the surface of the cervical canal or the uterus. Usually they are symptomless but when they show symptoms then they cause bleeding in post menopausal women like in your case.
However the hormones that you are taking for thyroid and cholesterol are likely to have less effect on the polyps which might have resulted in bleeding. This is because these drugs do not contain the female hormones and polyps are estrogen-sensitive, meaning that they respond to estrogen in the same way that the lining of your uterus does. So these drugs are less likely to be the cause of bleeding polyp.
However it is better to get the polyp removed and then continue with the hormonal drugs. Your gynecologist can remove the polyp by forceps, laser or cauterization. After removal the polyps should be sent for histopathological examination to rule out any neoplastic changes.
Hope this answers your query. If you have additional questions or follow up queries then please do not hesitate in writing to us. I will be happy to answer your queries.
Wishing you good health.
