Uncontrolled blood sugar. Patient also).

My father is chronically diabetic. Left toe amputation was done 1 month back. For its healing 1 PRP injection was given. His Hb was low.Wound was not getting red.He gave another PRP. Then doctor started iron and folic capsules and we started giving pomegranate, apple, beetroot juice daily from past 1 weak. Wound is somewhat red now. His blood sugar was under control since 1 month but from past 5 days fasting sugar in morning is high( consistently increasing daily-144, 155,167, 179). ) He is taking insulin injection 2 times a day( 30 in morning and 28 before dinner, Biphasic isophane) and other prescribed medicines. We don't know why sugar is high. From past 2 days there is slight more blurring of vision.(Retinopathy patient also).
