Thank you for your question.
I am Dr. SH and will be helping you out with your concerns.
Your loss of height is almost certainly not due to kidney disease.
However, if someone has weak bones (osteoporosis) the vertebrae in the spine can become compressed and you can lose a bit of height as a result.
But other than that I do not think that the loss of height is due to kidney disease.
You could possibly be imagining it as well.
