2 diabetes is when your body can’t make enough insulin, or use it well. Insulin helps
your cells use sugar (glucose) for energy. Without insulin, glucose builds up in your
blood. This leads to high blood sugar.
2 diabetes is an ongoing (chronic) disease. It has no known cure. It’s the most common
type of diabetes.

Diabetes can be diagnosed with several tests. It’s best to repeat the tests a second
time to confirm the results. The tests include:
Hemoglobin A1C test. This is the
A1C test. It measures your average blood glucose for the past 2 to 3 months. An A1C
of 6.5% or higher means you have diabetes. Some conditions can affect how accurate
the A1C test is. These conditions include sickle cell disease, pregnancy ,
glucose-6-phosphate dehydrogenase deficiency, HIV, hemodialysis, recent blood loss
transfusion, and erythropoietin therapy.
Fasting plasma glucose (FPG). This
test checks your blood glucose levels after 8 hours of fasting. You usually get this
test before your first meal of the day. This is called your fasting blood glucose
level. A result higher than or equal to 126 mg/dL means you have diabetes.
Oral glucose tolerance test (OGTT).
For this test, your glucose level is measured before and then after 2 hours after
drink a sugary drink. This shows how well your body processes glucose. A result of
200 mg/dL or higher after 2 hours means you have diabetes.
Random glucose test. This blood test
is done at any time of the day. Blood glucose of 200 mg/dL or higher with symptoms
high blood sugar means you have diabetes.
If you don’t have any symptoms of hyperglycemia, you will need to
have 2 abnormal test results from the same sample or in 2 separate test samples to
diagnosed. For example: a fasting plasma glucose greater than 126 and an A1C greater
than 6.5% from the same sample.
Treatment will depend on your symptoms, age, and general health. It
will also depend on how severe the condition is.

twice a year if your blood sugar level is in the target range and stable. You will

appointments. This is so your healthcare provider can track your diabetes. You will
