Sorry to hear you have osteoporosis also.
I decided on diet and exercise instead of bisphosphonates because I understood they decrease bone resorption (?) but not fractures. My choice may be why I had a recent worsening of a spinal compression fracture that generated my internist's suggestion to start using senna and docusate regularly.
Diet change involved my reducing salt intake, increasing calcium through supplements and more greens, then less meat and now NO meat or dairy. So my non-salty sauces based on citrus and vinegar are used with sweet potatoes, lentils and other beans.
I understand your hesitancy about Prolia. These are difficult choices.
