Have you been checked for diabetes?
Not much to go on..........but:
Obviously if these are thyroid issues, these symptoms are most common with hyperthyroid. The kidney not so much, unless its muscle in the area.
I am one of the few that loses weight when hypo. Many hypo/hyper symptoms crossover. This is where lab results help. If you have these , you can post them with the reference ranges for members insight.
