My aunt(56), is taking insulin (10-14 units) since last 3 years and is diabetic since decade. With medicine and insulin her
diabetes was under control, suddenly since last 2 months fasting is not in control. Consistently fasting is 150-200 since last 2 months which used to be 100 -120 earlier. She is taking full control over her diet and tried increasing insulin but causing no effect. Any tests recommended ?
