Diagnosis type 1 diabetes

Diagnosis type 1 diabetes

The sooner you discover an illness, the better. That also goes for diabetes type 1. Symptoms can develop quickly, even over days. If you suspect you have diabetes 1, visit your doctor as soon as possible.

Symptoms of diabetes type 1

The main symptoms of diabetes type 1 are excessive thirst, frequent urination, tiredness and weight loss. Other symptoms include blurred vision, skin infections, cramps or thrush. If you are also experiencing heavy breathing, nausea and vomiting, it is advised to seek medical attention immediately.


To diagnose type 1 diabetes, your doctor will ask about your symptoms and run some tests like a blood and urine test. A urine test will show whether your blood contains glucose. With diabetes type 1, glucose can pass through the kidneys into urine. After a urine test, the doctor can use a blood test to confirm the diagnosis of type 1 diabetes.

Blood tests

There are several blood tests. A glycated haemoglobin (A1C) test will indicate the average blood sugar level for the past several months. This test measures the percentage of blood sugar attached to hemoglobin (this is a protein in your red blood cells). The higher your blood glucose levels, the more hemoglobins with sugar attached will be find in your blood. Other blood tests that a doctor could use are a random blood sugar test or a fasting blood sugar test. The latter will be taken in the morning, before you had anything to eat.

If blood glucose levels are not high enough for a doctor to diagnose diabetes type 1, an oral glucose tolerance test (OGTT) is needed. In this cause, after drinking a glucose drink, blood samples will be taken every half an hour for two hours to find out how the body is dealing with the glucose.

After the diagnosis

After the diagnosis of type1 diabetes, it is advised to visit a doctor regularly to help you with diabetes management. Diabetes 1 is a chronic disease, but luckily there are plenty of measures you can take in order to live the life you want.
