Hi

Thanks for your query.

From your history,the recent blood test of blood glucose of 252( I presume its Random blood sugar values) and Hgb-1c of 7.2 , HbA1c( Hgb -1c) indicates the level of saturation of hemoglobin with blood sugars,which can be quantified and indicates the blood sugar levels in the past 3 months ,since it is 7.2, which is higherside of the normal, suggest Diabetes mellitus. But i suggest you to do Fasting blood sugar(FBS) and Post prandial blood sugar(PPBS) tests.

Since FBS and PPBS are cosidered more reliable as they indicate fluctuations in blood sugar levels and HbA1c is not affected by short-term fluctuations in blood glucose concentrations, it is used as a prognostic guide,the higher the values more the end organ damage( like Eyes-Retina, kidney, heart , etc).

Since your mother is on prednisolone medication, which is steroid drug, which can also causes in raised blood sugar level, depending on the dosage and duration.
Also the diabetic effects on retina can be made out through ophthalmic examination which also indicates the chronicity (duration)of the diabetes.

Considering the above points a suitable management( initiating antidiabetic treatment and decreasing the predinsolone sideeffects, diet care) can be done.

Hope I have answered your query. If you have any follow up queries I will be available to answer them

Hope your mother recover soon

Regards.
