Need guidance on regular basis for sugar

Hi, my Father age is 69, Having sugar problem from last 30 years, and BP from last 3 years. I have one Dr consultation on regular basis, offline visit is good and very good Dr. But for online I get stuck as I didn't get response timely. So I need someone who can be with me on urgent basis. Like some days ago my father sugar level goes to 50, but I get connect to Dr after 5-6 hr and he said to stop all diabetic medicine. And consult after 1 days. But I didn't get connect in next 36 hours. I don't know the reason but it seems that he is also old age and not tech savy. Getting medicine for sugar, bp, cholesterol, iron multivitamins. And all was good from last 3 years, but due to some extra roaming in holy places this sugar balance comes. So should I connect to different Dr who can with be on urgent basis when needed?
