What is the correct diagnosis of diabetes?

Q: I am 30 years old. I have had diabetes for a year now, but I don't have any symptoms. I have lost 5 kg. My sugar levels are stabilised without any medication. My fasting blood sugar varies between 70 & 90 mg/dl and Post prandial (PP) blood sugar varies between 100 & 130. I underwent glucose tolerance test (GTT). My FBS: 72 mg/dl; after half an hour: 131; after 1 hour: 166; after 1 and a half hour: 149; after 2 hours: 118; after 2 and a half hours: 96 mg/dl. Do I have diabetes or not?The lab technician has given 50 gm glucose saying that the amount of glucose in gm shall be equivalent to weight of person? My weight 47 kg. Is it correct?

A:The diagnosis of diabetes is made if an individual has symptoms of uncontrolled diabetes - polyuria (increased urination), polydipsia (increased thirst), nocturia (increased urination at night), fatigue or weight loss with a blood sugar level of >200 mg/dl or a fasting blood sugar level > 126 mg/dl on 2 occasions.In asymptomatic individuals whose random blood sugar level suggests diabetes, a fasting blood sugar concentration should be measured. The oral glucose tolerance test no longer is recommended for the routine diagnosis of diabetes. The person being tested starts the test in a fasting state (having no food or drink except water for at least 10 hours but not greater than 16 hours). An initial blood sugar is drawn and then the person is given a 75 grams of glucose (or 100 grams for pregnant women) and the blood sugar is tested again 30 minutes, 1 hour, 2 hours and 3 hours after the glucose intake. The amount should not be changed as this figure has been decided to standardise the test.Normal: If the 2-hour glucose level is less than or equal to 110 mg/dl. Impaired Fasting Glucose: If fasting glucose equal to or greater than 110 and less than 126 mg/dl. This is considered a risk factor for future diabetes, and will likely trigger another test in the future, but by itself, does not make the diagnosis of diabetes.Impaired Glucose Tolerance: If the 2-hour blood sugar level is > 140 but < 200 mg/dl. This is also considered a risk factor for future diabetes. Diabetes: If the blood sugar level at 2 hours is > 200 mg/dl. This must be confirmed by a second test.Your test is absolutely normal and there is no cause for worry.
