Hello, Welcome to health care magic. I have read your question completely and understand your concerns. Excessive thirst, frequent urination and fungal infections can all occur in a diabetic patient if their blood glucose is not well controlled. For good diabetes control, fasting blood glucose should be less than 110, 2 hour post prandial should be less than 160-170 and HbA1C which is there 3 month average blood glucose should be around 6.5-7% ( depending on the age, and any other medical complications). You could get the above blood tests done and consult your doctor. If your blood glucose is in the normal, you still need to see your doctor to rule out other causes of your symptoms. I hope this answer has helped you Thank you Regards Dr Sunita Sayammagaru
