question: Hi doctor, I am 35 years old. I am married for last 4 years and having a kid. I led a sedentary lifestyle. My fasting blood sugar was 257 and PP was 353. My HbA1c was 11.3. I was diagnosed to have diabetes. I consulted my friend with is a doctor and under his guidance, I changed my diet and started the exercise. I reduced my weight from 103 kg to 91.2 kg. After three months, my fasting was 117 and PP 153 with HbA1c 6.5. My lipid profile is normal. For the past one week, when I check my glucose level in glucometer at home, it is less than 110. I am not in diabetes medicine. I think I have ED. What are the test that needs to be done to diagnose the same?
