At 45, Lydie Pincemin was misdiagnosed with type 2 diabetes when she actually had type 1 diabetes. Astonishingly, up to 40% of adults over 30 with T1D are initially misdiagnosed as type 2. Understanding that T1D can strike at any age is crucial for receiving life-saving treatment.
During a vacation in the U.S. with her daughter, mom, and mother-in-law, Lydie suddenly felt incredibly sick, spiking a fever of 107°F. Unable to board her flight home, she was rushed to the ER in Florida. Reflecting on the incident, Lydie realized she had been experiencing typical T1D symptoms—excessive thirst, frequent urination, and vision changes. However, she attributed her fatigue and mood swings to "long COVID," which she had been battling since contracting the virus two years prior.
In the ER, Lydie’s blood glucose levels were sky-high, and she was diagnosed with diabetic ketoacidosis. Thankfully, the doctors immediately started her on insulin, which isn’t always the case with misdiagnoses. Alongside DKA, Lydie was also battling double-lung pneumonia, resulting in a four-day stay in intensive care. She was later transported to Quebec City for further treatment.
Lydie’s father had been diagnosed with type 2 diabetes at 45, leading her doctors to quickly assume the same for her. But this assumption nearly cost Lydie her life. In Canada, an astute endocrinologist reviewed her medical history and COVID infection, then tested her for autoantibodies. The result? Type 1 diabetes, not type 2.
Autoantibodies, the early markers of T1D, can appear years before symptoms. Early identification is key to accessing clinical trials to delay or prevent T1D. Today, Lydie is getting her daughter tested for T1D autoantibodies, recognizing the importance of early detection even without a strong family history. If you or a loved one has diabetes, consider autoantibody testing. It’s a simple step that can lead to significant preventive care.
