Hi court, welcome to HealingWell!
Are you on calcium for the osteoporosis? If so, that could be your main contribution to constipation. Have you talked to your doctor about
this possible connection? Have you tried other alternatives for the constipation, like prune juice, high fiber diet or Zelnorm? (I only mention Zelnorm because it is not as addictive as laxatives.) Do you get plenty of exercise and drink lots of water? Lots of people don't have regular BM's because they don't get enough exercise and/or water.
As for the bloating... have you tried Beano or Gas-X? Other than avoiding gaseous foods, those are the only 2 things I can think of to help with the bloat.
