Early Detection of Type 1 Diabetes: Why Screening Matters (2025)

Imagine discovering a life-altering condition before it becomes a crisis. That's the power of early type 1 diabetes (T1D) detection, a topic gaining momentum thanks to advocates like Shara Bialo, MD, a pediatric endocrinologist and T1D warrior herself. During American Diabetes Month, Dr. Bialo, senior medical director at Sanofi, champions the game-changing potential of autoantibody screening, a tool that can rewrite the narrative for those at risk.

In a recent conversation with Pharmacy Times® (https://www.pharmacytimes.com/view/what-health-care-professionals-should-know-about-early-type-1-diabetes-screening), Dr. Bialo highlights the stark reality: 64,000 people are diagnosed with T1D annually, most of them adults, shattering the myth that it's solely a childhood disease. But here's where it gets even more critical: a staggering number of these diagnoses come with diabetic ketoacidosis (DKA), a life-threatening complication where the body, starved for glucose, resorts to burning ketones for energy.

Dr. Bialo's own story is a testament to the urgency. Diagnosed with DKA, she slipped into a coma, leaving her parents reeling. This is the part most people miss: early detection through autoantibody screening could have prevented this traumatic experience. Studies show that screening high-risk individuals can virtually eliminate DKA at onset, a monumental leap forward in patient care.

Beyond the medical benefits, early detection offers something invaluable: time. Time for families to process the diagnosis, time to learn about insulin therapy, and time to prepare emotionally for the journey ahead. And this is the part that sparks debate: some worry about the anxiety of knowing about a potential future condition. But Dr. Bialo counters that the long-term psychological benefits outweigh any initial concerns.

Despite its promise, autoantibody screening isn't yet widespread. Dr. Bialo identifies key hurdles: clinician awareness about the three stages of T1D, the logistics of incorporating screening into busy practices, and reimbursement concerns. Here's a thought-provoking question: should we prioritize broader screening, even for those without a family history, considering 90% of new T1D cases arise without any familial link?

Pharmacists, Dr. Bialo emphasizes, are crucial allies in this fight. Their frequent interactions with patients provide prime opportunities to educate about T1D risk, especially for those with a family history (up to 15 times higher risk!) or autoimmune conditions. By initiating conversations and encouraging screening, pharmacists can empower families to take control of their health.

Repetition is key, Dr. Bialo stresses. When patients hear about screening from multiple trusted sources – pharmacists, primary care physicians, endocrinologists – the message resonates, leading to action.

The tide is turning. Improved research, clear medical guidelines from organizations like the American Diabetes Association, and passionate advocates like Dr. Bialo are paving the way for a future where early T1D detection is the norm, not the exception.
