Glucose Tolerance Test – This measures your blood sugar before and after you drink a liquid that contains glucose. You’ll fast (not eat) overnight before the test and have your blood drawn to determine your fasting blood sugar level. Then you’ll drink the liquid and have your blood sugar level checked 1 hour, 2 hours, and possibly 3 hours afterward.
How do you get a diagnosis of diabetes?
Type 2 diabetes is often diagnosed following blood or urine tests for something else. However, you should see a GP straight away if you have any symptoms of diabetes, To find out if you have type 2 diabetes, you usually have to go through the following steps:
- See a GP about your symptoms.
- The GP will check your urine and arrange a blood test to check your blood sugar levels. It usually takes about 1 to 2 days for the results to come back.
- If you have diabetes, the GP will explain the test results and what will happen next.

Signs, Symptoms and Diagnosis of Diabetes
- Signs, Symptoms and Diagnosis of Diabetes
The signs and symptoms of Type 1 diabetes usually develop quickly, especially in children, over a period of weeks. In babies and young children, the first indication of Type 1 diabetes may be a yeast infection that causes a severe diaper rash that’s far worse than the common red, puffy and tender skin rash.
- In young children and infants, lethargy, dehydration and abdominal pain also may indicate Type 1 diabetes.
- Once the symptoms appear, a blood test generally will reveal very high blood glucose.
- Type 2 diabetes can be detected easily during a routine screening exam and blood test.
- However, it frequently can go undiagnosed for years unless a physician draws a blood sample to check the blood glucose.
In the early stages of Type 2 diabetes, you experience few to no noticeable signs of the disease. As time goes by and the untreated blood glucose continues to rise, symptoms begin. If you’re over 40 or have parents or siblings with diabetes, be sure to have your blood glucose checked routinely.
- Extreme thirst and a greater need to urinate: As excess glucose (sugar) builds up in the bloodstream, fluid is pulled from the tissues. The loss of fluid makes you thirsty. As a result, you may drink and urinate more than usual.
- Frequent hunger: Without enough insulin to move sugar into the cells (Type 1) or insulin resistance prohibiting insulin from entering the cells (Type 2), the muscles and organs are low on energy. This triggers intense hunger.
- Weight loss: Despite eating more than usual to relieve hunger, rapid weight loss sometimes occurs. Without the energy that glucose supplies, muscle tissues and fat stores simply shrink. Unexplained weight loss is often one of the first symptoms to be noticed.
- Blurred vision: If the blood glucose is too high, fluid may be pulled from the lenses of the eyes, affecting the person’s ability to focus clearly.
- Feeling tired: If cells are deprived of sugar, you may become tired and lethargic.
- Slow-healing sores, yeast infections, urinary tract infections, etc.: High blood glucose reduces the immune system’s ability to fight infections.
At what age is type 2 diabetes usually diagnosed?
Healthy eating is your recipe for managing diabetes. More than 37 million Americans have diabetes (about 1 in 10), and approximately 90-95% of them have type 2 diabetes. Type 2 diabetes most often develops in people over age 45, but more and more children, teens, and young adults are also developing it.
Is it prediabetes or diabetes?
Fasting blood sugar test – A blood sample is taken after you haven’t eaten for at least eight hours or overnight (fast). Blood sugar values are expressed in milligrams of sugar per deciliter (mg/dL) or millimoles of sugar per liter (mmol/L) of blood. In general:
Less than 100 mg/dL (5.6 mmol/L ) is normal 100 to 125 mg/dL (5.6 to 6.9 mmol/L ) is diagnosed as prediabetes 126 mg/dL (7.0 mmol/L ) or higher on two separate tests is diagnosed as diabetes
How is diabetes diagnosed in adults?
Hemoglobin A1C Test – The hemoglobin A1C is a highly sensitive and accurate blood test for diagnosing type 2 diabetes. It measures your average blood sugar level over a two- or three-month period to determine whether it is consistently high. Because the sugar remains attached to hemoglobin—a protein in red blood cells that carries oxygen to tissues throughout the body—for up to four months, it’s a good indicator of average blood sugar levels.
