Concerned my grandmother is under too much diabetes medicine and can cause complications?

Being tired and fatigued are signs of too much sugar in the blood. The Dr is adding medications because your grandmothers blood sugars are too high. Most of the time they base their decisions to raise doses on a test called a hemoglobin A1C test. This tests the range of how high her average blood sugar is. As you know, when we eat our blood sugar spikes then insulin kicks in to bring it down. Many people test their blood first thing in the morning before food. Blood sugar should be 80-100 normally and spike to about 110-120 after we eat. If she is running 200-300 in the morning, imagine where she is after eating. A hemoglobin A1C will give a number that tells the Dr about where her average sugar runs. Your grandmother needs to get a better hold on her diet. She is eating wayy too many carbs, plain and simple. If she reduces her carb intake then she can reduce her intake of meds. With her doses being this high, she is really close to needing insulin therapy.

She would probably feel better if she started taking insulin. If she doesnt want to be on insulin then she really needs to change her dietary habits. She might look into some diabetic education classes. She can check with the local hospitals as to where she can find a class to go to to educate her on eating a correct diet and how to count carbs. This is the only way to truly bring sugars down. Many people can actually stop taking diabetic meds altogether when they lose weight and eat less carbs.
