39 and 41 are very low values, hypoglycemia are considered.You should consult with the doctor because it is probably because they have put too much insulin for what you eat.That they explain well how to adjust the insulin depending on the hydrates you eat and the glucose values you have when you measure yourself.It is dangerous to have such low glucose. Have you not told you how to act in a hypoglycemia?You have to take some food with sugar (juices, sugar milk ...) or pure glucose pills or gels (it is the fastest acting) to trace hypoglycemia. If you put more information about what the doctor told you, I can tell you something else, not specific what medication they have put you.
They did not give me insulin they only told me to follow a diet in my house.Now the value he gave me on an empty stomach was 81, before eating 85 and after eating 97 is it wrong?I'm improving ???
These levels are very good @"Danielacapra", the last ones you say, the previous ones are dangerous.If they repeat yourself, you should go to your doctor and as they tell you above, as long as you have such low levels you have to drink something that replenishes that glucose, a juice or some sugary drink, at 15 minutes repeat the blood glucose, ifIt is climbing, perfect and if not then taking some carbohydrate too, with a cookie or a little fruit usually.
