My body is not absorbing estrogen prescribed by my doc. blood tests showed non existent. i'm post menopausal. dizzy, tired, headaches, sad, irritabl?

Different route: How are you taking the estrogen? There are many forms and ways to get it in your body. You may want to try something different. There are sprays, creams, gels, patches, a vaginal ring, and pills. Pick one, start low, and go up on the dose slowly until you get some relief! it can take months to stabilize. Make sure you don't also have other hormonal deficiencies, like thyroid.
