My father age is 69 years old, For past 3 years he is taking tablet for dietetics, Now his sugar level has been increased a lot but he is not taking that much sugar too, Before food 215 mg, after food 330 some what. I do not know how to reduce his sugar level without going for insulin. Please advice me, what action can be taken. Whether he needs to take any test, if yes please tell me the test report names so that I will check near by lab. He is taking Amedop AT tablet for BP too. He got stoke in the year 2000. Because of that his left side function is not good. Please provide your response as soon as possible.
