Key takeaways

A therapy called teplizumab (Teal) is FDA-approved and can delay the onset of Type 1 diabetes in people identified as at-risk
Screening for Type 1 diabetes risk is possible through blood work and is especially relevant for people with a strong family history
Gestational diabetes during pregnancy and elevated blood sugar after birth can be a signal to ask for Type 1 diabetes screening, not just Type 2 diabetes diagnosis
Self-advocacy with your healthcare team matters—mentioning family history can open doors to appropriate specialist referrals

A Family Pattern Points the Way

Sierra grew up knowing Type 1 diabetes well. Two of her aunts were diagnosed in their 20s, one cousin had juvenile diabetes, and another cousin was diagnosed at 43. That family history would later become crucial information.

When Sierra became pregnant in 2019, she was screened for gestational diabetes as part of routine prenatal care. During her first glucose tolerance test, her blood sugar was elevated enough that her doctor started her on insulin immediately. She remained on a relatively high insulin dose for the rest of her pregnancy.

The Question That Changed Everything

After giving birth, Sierra's blood sugar didn't return to normal ranges. At her first postpartum follow-up with her VA doctor, her A1C was measured at 6.6—the highest it had ever been. Her doctor suggested a Type 2 diabetes diagnosis and proposed long-term metformin therapy.

But Sierra remembered her family history. She advocated for herself, mentioning the multiple relatives with Type 1 diabetes in her family. Her doctor agreed to refer her to an endocrinologist for further evaluation—a step that opened the door to screening for Type 1 diabetes risk.

What This Story Illustrates

Sierra's experience highlights an important reality: Type 1 diabetes can sometimes be missed or misidentified, especially in adults. A strong family history combined with blood sugar abnormalities warrants specialized evaluation, not just a presumed Type 2 diagnosis.

For people identified as at-risk for Type 1 diabetes through screening, an approved therapy called teplizumab (Teal) exists. This therapy has been shown to delay the onset of Type 1 diabetes. Sierra pursued screening and ultimately received this therapy—a path that was only possible because she asked the right questions and her healthcare team listened.
