Well, I'll go to the point My father has diabetes enough years ago. Yesterday he suffered a decompensation and had to be taken to the hospital Today dawn much better, but now a few hours ago, I was under the pressure and had chills, suffering many shots, together with a lot of sweat and also sleep.
I don't know what about it, it is not the idea to take it every day.
I suggest that you consult the specialist (endocrine) and to value your father's situation, not only how his diabetes controls but to evaluate the presence of possible complications (eyes, kidney, feet), blood pressure, cholesterol ...
They can be symptoms of hypoglycemia, I suppose it will have glucometer to control.If the glucose is below 70, you have to drink a glass of juice or something with sugar.If the medication has changed and has hypoglycemia you will have to lower the dose.Tell him with the doctor.
