Do you know that I had the bone scan done in my early 30's and was told I had the start of osteoporosis? But I was VERY skinny, work out queen then and they said that was common if you fit in to that category. Are you very thin? Just asking. But in general, as we lose estrogen during menopause, osteoporosis is more likely to develop. Here's a fact sheet on it. https://www.niams.nih.gov/Health_Info/Bone/Osteoporosis/osteoporosis_ff.asp Just one more pain in the butt thing to think about as we get older. Grrr.
Just had a bone scan and my bones are great for a 51 year old and I am slightly overweight and in menopause, but my mother and grandmother have/had great bones. The extra weight is like weight bearing for those bones. I do strength training mixed with aerobic exercise. I say get out and walk more (brisk) and avoid excessively sitting. Too much sitting is terrible for someone with back issues. Yes, I know all about that. You want to sit when you have pain, but that actually only makes the situation worse. Has to be a balance between sitting and moving. What's your weight lifting regimen like? Free weights or Nautilus equipment? Again, increase your walking. As far as your medications you definitely should follow the advise of your physician. And no, you aren't too young to have osteoporosis. My sister-law-in has it and she is underweight and doesn't do much sport or activity. Weight lifting and nothing else isn't going to do much. You're vegan too, which means your calcium intake isn't the best. I don't really believe in extreme ways of eating unless your physician recommends that. Vegan is too extreme for an older woman in my opinion, but that's for you to discuss with your physician.
