A general weakness of the body, often caused by illness, injury, or age.

means A weakening or loss of strength, especially the kind caused by illness, injury, or age.

from From Latin debilitas, 'weakness,' built from debilis meaning 'weak' or 'disabled' — itself from de- (away, down) plus an old root related to 'strength' or 'power,' so the word literally paints strength as something drained away. It passed through French into English in roughly its current form, kept mostly in medical and formal use ever since.
