Hi there. Thank you for the query. You are doing fantastic by avoiding excess sugars and oil. Having your HbA1c more than 7% suggests your blood glucose levels were always more than 200 mg/dl, on an average, at least since past 3 months. And as you correctly said you cannot afford to stay with these kinds of high sugars for a long period. I would like to know - your age - weight and height - if you have been taking any oral medications like metformin, pioglitazone, vildagliptin etc to help your insulin shots to work better - if you have high BP or any other diabetes related complication This information will assist me to tell you how to tackle your insulin doses, whether addition of any oral medication will help at this stage or not. If I have to answer you on the basis of information you have provided here, then I would suggest that change of Inj Huma 30/70 to Inj Huma 50/50 with addition of about 2 units each in the current doses will help your average sugar to come down. You also need to know the patterns of your fasting as well as your post-meal sugars along with HbA1c levels. Depending on that we can further manipulate the Huma doses. But you can consult your doctor on this first. Your second question if you are on too much of artificial insulin. Total amount of insulin need depends on - your weight- whether it is too much for your height - your duration of diabetes which is already more than 10 years - whether you also take oral anti-diabetes medications or not - whether you have any diabetes related complications or not - How much is your physical activity All these factors decide one s need of total amount of insulin. But one thing is clear there is not any upper limit of dose of insulin. As long as your blood glucose levels are not under control, one needs to titrate the insulin doses to optimum levels once other factors (listed above) are taken care. So if there is need to increase your doses, you must listen to your doctor s advice to do so as controlling blood glucose is more important. Thirdly, your burning sensation during urination while your sugars are high suggest you really need to drink lots of water to flush the excess sugar out, to dilute your plasma glucose, to flush the bacteria in urinary tract which grow in higher sugar mediums, and of couse increase the doses of anti-diabetes medications. If the symptoms persist, then make sure you carry out urine routine and microscopic test to rule out urinary tract infection. I hope this helps you. Do get back for any further query.
