I am 18 years old and I have tested my fasting glucose at home and it was 5.9, which is very high. Next I ate 2 bowls of dessert then 90 mins later I tested my glucose and it was 5.72. A1c came out to be 36 mmol/mol. Is there something wrong with me, am I developing diabetes, have my insulin resistance genes revealed? If anyone can reply I will be delighted!
