Diabetes and walk

I have a friend who is Diabetes Mellitus-2 and that her endocrine has sent him to take Dianben a pill in the morning at breakfast and another at dinner.Lately he has noticed that when he goes out to walk in the mornings he loses all the energy, it shows decay and when he arrives home it has 68 glucose, when normal his measure is 110. Should I stop taking the dianben in the morning and only takeThe night?

Just before the exercise you try to eat a couple of cookies, normal ... that will upload about 50 mg/dl of blood glucose.

Metformin should not produce hypoglycemia, so perhaps before the exercise and of the right glymia values

If those 2 cookies are eating very justice of glycemia, it should comment on the doctor and rethink the treatment.
Perhaps if it has reduced the weight and maintains the exercise daily, only with the tablet of the night it might be enough.

Thanks Owash.
