Diabetes is a chronic condition that affects how your body processes sugar (glucose), one of the main sources of fuel for the body’s cells. There are three main types of diabetes: type 1, type 2, and gestational diabetes. All three types of diabetes are characterized by high blood sugar levels, but they have different causes and risk factors.
To diagnose diabetes, healthcare providers use specific criteria based on the patient’s symptoms and test results. In this post, we’ll take a closer look at the diagnostic criteria for each type of diabetes and the tests that are used to make a diagnosis.
Diagnostic criteria Type 1 Diabetes
Type 1 diabetes is an autoimmune disorder in which the body’s immune system attacks and destroys the cells in the pancreas that produce insulin. Insulin is a hormone that helps regulate blood sugar levels by allowing glucose to enter the cells for energy. Without enough insulin, glucose builds up in the bloodstream, leading to high blood sugar levels (also known as hyperglycemia).
Type 1 diabetes is usually diagnosed in children and young adults, but it can occur at any age. The diagnostic criteria for type 1 diabetes include:
- Symptoms of hyperglycemia (such as frequent urination, excessive thirst, and unexplained weight loss)
- A blood sugar level of 200 mg/dL or higher after an overnight fast (also known as an oral glucose tolerance test)
- A positive test for the presence of ketones (byproducts of fat breakdown) in the urine or blood

People with diabetes are especially vulnerable to the dangers of colds and the flu, but there are things you can do to control your symptoms and avoid getting sick in the first place. You may maintain your health even when you’re feeling under the weather by constantly monitoring your blood sugar levels, staying hydrated, getting enough of rest, and adhering to your diabetes management plan. Additionally, you may lower your risk of getting sick and safeguard yourself from any problems by maintaining proper cleanliness, being vaccinated, and generally maintaining good health. Make sure to discuss any worries you may have with your healthcare team for advice and support if you have diabetes and are worried about managing colds and the flu.
Diagnostic criteria Type 2 Diabetes
Type 2 diabetes is the most common form of diabetes. It occurs when the body becomes resistant to insulin or doesn’t produce enough insulin to keep blood sugar levels in check. Type 2 diabetes is often associated with being overweight or obese, having a sedentary lifestyle, and having a family history of diabetes. However, it can also occur in people who are at a normal weight and are physically active.
The diagnostic criteria for type 2 diabetes include:
- Symptoms of hyperglycemia (such as frequent urination, excessive thirst, and unexplained weight loss)
- A blood sugar level of 200 mg/dL or higher after an overnight fast (oral glucose tolerance test)
- A blood sugar level of 126 mg/dL or higher on two separate occasions (fasting plasma glucose test)
Diagnostic criteria Gestational Diabetes
Gestational diabetes is a form of diabetes that occurs during pregnancy. It occurs when the body becomes resistant to insulin or doesn’t produce enough insulin to meet the increased demand for insulin during pregnancy. Gestational diabetes usually goes away after pregnancy, but it increases the risk of developing type 2 diabetes later in life.
The diagnostic criteria for gestational diabetes include:
- A blood sugar level of 140 mg/dL or higher on a glucose tolerance test after an overnight fast and at the end of the test (usually performed between 24 and 28 weeks of pregnancy)
- A blood sugar level of 200 mg/dL or higher on a glucose tolerance test two hours after drinking a glucose solution
Other Tests
In addition to the tests mentioned above, healthcare providers may also use the following tests to diagnose diabetes or monitor blood sugar levels:
- HbA1c test: This test measures the average blood sugar level over the past 2-3 months by looking at the amount of sugar attached to red blood cells. A level of 6.5% or higher on two separate occasions indicates diabetes.
- Random blood sugar test: This test measures the blood sugar level at any time
In conclusion, the diagnostic criteria for diabetes vary depending on the type of diabetes and the stage of diagnosis. It’s important to work with a healthcare provider to determine the most appropriate test or combination of tests to diagnose diabetes and monitor blood sugar levels. If you have any symptoms of diabetes or are at high risk of developing the condition, it’s important to speak with a healthcare provider to discuss your risk and available testing options. Early diagnosis and treatment of diabetes can help prevent or delay the development of serious complications such as nerve damage, kidney disease, and cardiovascular disease.
