How Type 2 Diabetes Is Diagnosed

If you have symptoms of increased thirst, increased hunger, frequent urination, tingling of your hands or feet, unexplained weight loss – your doctor will have reason to believe you have diabetes.

A fasting plasma glucose test or a plasma glucose test will be conducted to confirm the diagnosis.

Fasting Plasma Glucose Test

The fasting plasma glucose test (FPG) is the preferred technique to confirm a diagnosis of diabetes since it is easy to do and less expensive compared to other tests.

Your doctor will instruct you not to eat anything for 12 hours before the FPG test.

A small amount of blood will be extracted from you and sent to the lab for analysis.

Normal fasting blood glucose range from 70 to 100 milligrams per deciliter or mg/dL for non-diabetics. A diagnosis of diabetes is confirmed when two separate blood tests show that your fasting blood glucose level is greater than or equal to 126 mg/dL.

But, in case you have a normal FPG, and show symptoms or have risk factors for diabetes, your doctor will opt to do a glucose tolerance test to ensure that you do not have diabetes.

Casual Plasma Glucose Test

The casual plasma glucose test is also a procedure for diagnosing diabetes. In this test, blood glucose is checked without regard to the time since your last meal. You do not need to abstain from eating before the test.

A glucose level greater than 200 mg/dL may suggest diabetes, especially if the test is done again at a later time and reflects identical results.

Oral Glucose Tolerance Test

The oral glucose tolerance test is yet one more procedure useful to identify diabetes. However, it is often just performed during pregnancy to diagnose gestational diabetes or for an individual who is thought to have type 2 diabetes but has a normal fasting glucose level. It will also be performed to diagnose pre-diabetes.

Your Diagnosis

Diabetes can result in major health problems unless you keep your blood glucose under control. On the other hand, it is possible to stay healthy and feel good despite your diagnosis if you strictly follow your doctor’s recommended treatment plan and keep a healthy lifestyle. By selecting foods intelligently, exercising regularly, maintaining a normal weight, decreasing your stress level and making other modest lifestyle changes, coping with diabetes will be easier.
