Dad complains of weakness in his legs such that he has difficulty going up the stairs. He is 83. His upper body strength is ok. He says he has felt depressed lately. He has a pacemaker. He recently suffered a fall when he seemed to have lost consciousness while trying to pick up something on the floor. His appetite is good. His only complaint really is his weakness; and he has lost weight too. How does he regain his weight?
Hi, looking at his age, he may also be having pain in knees which may also be causing weakness, moreover neurological involvement during fall may also be the reason, consult a neurologist first, if he rules out any of his intervention, then you may plan to go to an or tho doctor for help.
