Hi Aurori
With 50 or 70 it is advisable to drink sugar (a glass of water or fruit juice with sugar and a pair of cookies), rest and at 10 minutes re -measure to see if the blood glucose is above 100.
We would need to know some things to be able to comment more accurately:
I imagine that the units you say are mixed insulin, with names like Mixtard 30 (the clock), Novomix 30, Humalog Mix 25 or 50, Insulatard ... or maybe you put on another type of insulin.
It is important that you also know what you eat, you never have to skip any food or stop eating carbohydrates, carbohydrates is what allows the human body to function, without them and with excessive insulin in the body we have guaranteed hypoglycemia.
We usually explain children:
- Everything that is born from Earth are carbohydrates (fruits, vegetables, cereals ...) And also milk.
- Everything that runs, nothing or flies does not raise glycemia
If you eat excessive carbohydrates for the insulin you get you will have very high values.
If you eat less carbohydrates for the insulin you get you will have very low values.
In summary, and even if it is a vacation, I would ask for an appointment with someone to explain well what diabetes (insulin+food+exercise) is, it can be an endocrine, it can be an educator nurse in diabetes (in many hospitals with unitsThere are diabetes) or even in primary care you can find someone to explain it in depth.
Another possibility is to prove fortune in an association of diabetics, in many of them they have a diabetes educator.
Finally, change the needle after each puncture, never reuse the needles ... If you do it, in addition to doing more damage you have the danger of getting less insulin than marks (if they use them a lot they are embozan, so to speak).
I imagine that instead of clarifying something I have brought you more:-/
