First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether measuring pancreatic polypeptide levels after a meal can help doctors tell the difference between type 1 diabetes and type 3c diabetes (caused by pancreas damage). Thirty-six adults with either type 1 or type 3c diabetes gave blood and stool samples. The goal was to see if this simple test could improve diabetes classification and guide treatment.
