Dear Vinod, It is not clear from your question whether your mother was already on medication for control of blood sugar before she took the test. However your statement that your doctor changed the medications suggest that she already was on medications. The empty stomach report which is known as fasting blood sugar of 90 mg% is perfect. The 190 mg in the post prandial blood sugar test (PP2BS)is more than the required normal range of 120 mg% - 150 mg%. For getting optimum blood sugar control in patients of maturity onset diabetes mellitus together with the type of medication, dosage and timing is very important. If all these things are not taken care of it can lead to poor control of blood sugar levels with long term problems or hypoglycemic episodes with equally disastrous results. From the look of it, it seems that your mother has a problem with handling extroneous sugar in the form of food. At a basal level her body is capable of handling the blood sugar levels. for such a patient it is good to have a combination of pioglitazone with methformin preferably before breakfast. Evening dosages are better avoided. Also six monthly Hb1ac test will help in assessing whether blood sugar levels have been adequae or not.
