BPD-DS done in 2007 15 years post op. I have severe Osteoporosis due to malabsorption, mostly self inflicted by not being diligent with my vitamins and supplements. Stopped losing weight, eating a good healthy diet, assumed I was getting what I needed did not take supplements on a regular basis. Fast forward to today, I've been faithfully taking vitamins, calcium, iron for about 2 years now but I can't seem to slow the cycle of osteoporosis. I'm taking tymlos injections nightly, but my bone scans steadily decline. Any suggestions for Oral or patch Calcium that is extremely quickly absorbable please share info.
