Very possible, but one must also consider degenerative osteoarthritis. I've shrunk 3/4 inch since 1996, 1.5 inches since 1980. My doctor said this may not be due to compression fractures of the spine related to osteoporosis, but possibly degeneration of discs between spinal vertebrae causing loss of height and pain. With his pain, I would definitely consult with an orthopedist, or bone specialist. Hope this helps.
