Diabetes can develop after pancreatitis or pancreatic surgery because pancreatic disease can affect the cells that make insulin. This is often called pancreatic, pancreatogenic, or type 3c diabetes. Understanding the cause matters because some people […]

How glucose, lipid, and kidney results support metabolic-risk assessment in people with established type 1 diabetes.

Yes. A person can have autoimmune type 1 diabetes and insulin resistance at the same time. Type 1 diabetes describes an immune-related loss of insulin-producing cells. Insulin resistance describes a reduced response to insulin in […]

HOMA2-IR, HOMA2-%B, and HOMA2-%S Explained

What the fasting HOMA2 model can—and cannot—tell you about insulin sensitivity, insulin resistance, and beta-cell activity.

HOMA2-IR, HOMA2-%B & HOMA2-%S Explained Direct answer: HOMA2 is a nonlinear computer model, not a stand-alone blood test. From compatible fasting glucose with insulin or C-peptide, it estimates insulin sensitivity (HOMA2-%S), the reciprocal insulin-resistance index […]
