Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
It seems that your
diabetes is well out of control. Stopping
Dapagliflozin (Farxiga) is not a good enough reason to explain the rise in
HbA1c levels. Perhaps you should check your food intake as well? The quantity and quality of food is an important parameter. Another really important parameter is physical activity. Walking every day (or at least every other day) is as effective as a new pill. 20-30 minutes of fast walking is enough.
Regarding your current regimen. I usually advise patients like you to increase their
insulin dosage gradually until they reach acceptable fasting measurements. For older patients a little higher readings are acceptable as well. Targeting a fasting blood
glucose around 100 mg% per day is fine.
When the fasting blood sugar gets under control again, you can start checking your postprandial glucose levels. You can send another question then.
Until you get your blood sugar under control again, make sure you drink enough fluids.
Dehydration is a danger is your water intake cannot match the increased losses due to
hyperglycemia.
I hope you find my comments helpful! You can get back to me if you'd like more information or any clarification.
