Question from Pennsylvania, USA:
I am a 63 year old woman, who has diabetes for 10 years. I would like to know what effect potassium has on NPH insulin if any. And can a thiazide (water pill) raise your blood sugar when taking insulin?
Yes, thiazide diuretics can cause your blood sugar to be higher, whether you take insulin or pills to manage your diabetes. I do not know of any relationship between potassium and NPH insulin.
