My father is a
sugar patient since 15-20 years but from last couple of years post his retirement we noticed that he has become very lethargic (I mean he doesn't speak much, he doesn't smile much, became less responsive). His Sugar is under control (70/138) with medication. He was a very jolly person and was very active but not sure what happened ? Is it because of lack of any
vitamin ?
I would highly appreciate if you could guide me whom should I consult and what are the possible reasons of this.
