My father (aged 90) is not very mobile. His legs become swollen due to water retention. He cannot lie flat due to arthritic hip and sleeps sitting up in a chair. This makes swelling even more likely. For a few weeks now he has been wearing tight-fitting stockings to prevent the swelling but complains they are uncomfortable and wants to take them off.
Is there medication that can force the body to get rid of excess water so it passes out of the system through the bladder? Would any such medication remove the need to wear the stockings?
Thanks in advance.
