Why does the result obtained by self-monitoring blood sugar during pregnancy differ greatly when measured every two minutes?

Patient's question:

No

Doctor's answer:

Diabetes is the damage to pancreatic beta cells or pancreatic resistance. The former is type 1 diabetes, and the latter is type 2 diabetes. The pathogenesis of diabetes is currently unclear. Clinically, it cannot be cured, and the main goal is to control blood sugar. Currently, surgical treatment is not available.
