Why is Type 1 Diabetes Misdiagnosed?

Many people with Type 1 share a similar diagnosis story. They display all the classic symptoms (extreme thirst, weight loss, frequent urination, nausea) and were fortunate enough to be accurately diagnosed by their primary care doctor. However, some people with Type 1 are not as fortunate to quickly receive a correct diagnosis.

It is important to remember that the only way to have an accurate diagnosis of Type 1 diabetes is to test for the diabetes-related (islet) autoantibodies.

If ICA, GADA, and/or IA-2A are present in a person with diabetes symptoms, then you have confirmation that the diagnosis is Type 1 diabetes. If IAA is present in a child with diabetes who is not using insulin, then the diagnosis is Type 1 instead of Type 2.

If no diabetes-related autoantibodies are present, then it is unlikely that the diagnosis is Type 1 diabetes. Only in extremely rare incidents does someone have Type 1 and does not develop detectable amounts of islet autoantibodies. Some people who have type 1 diabetes will never develop detectable amounts of islet autoantibodies, but this is rare. Approximately, 95% or more of people with new-onset Type 1 diabetes will have at least one islet autoantibody (labtestsonline.org).

The following are some conditions and ailments that people are often misdiagnosed with after first experiencing symptoms of Type 1 diabetes. A misdiagnosis can be extremely dangerous and in some cases, fatal.

Type 2 diabetes

A common misdiagnosis is the other “type:” Type 2 diabetes, as most of the early symptoms are the same or very similar to that of a Type 1 diagnosis. Depending on your current state of health, weight fluctuations, eating habits, and other factors – a medical professional may wrongly assume that you are suffering from Type 2.

Gestational diabetes

While a woman is pregnant, she can be diagnosed with gestational diabetes. Gestational diabetes is a form of diabetes that only occurs during pregnancy, resulting in improper insulin responses but can resolve itself after giving birth. If it does not resolve, the diagnosis could be Type 1 or 2 diabetes.

Stomach flu

Extreme high blood sugar in conjunction with DKA (Diabetic Ketoacidosis) is the primary symptom of a Type 1 diagnosis. High blood sugar levels can cause nausea, vomiting, lethargy and other symptoms that, if blood glucose levels are not tested, can be easily diagnosed as a stomach flu or another common virus.

Eating disorders

Extreme weight loss due to high blood sugar and DKA is a very common symptom that goes along with a Type 1 diagnosis. If urine and blood glucose tests are not performed when seeing a doctor, an incorrect assumption could be that the patient is purposely losing weight and may be diagnosed with an eating disorder such as anorexia or bulimia.
