Pattern Overview
Yin Deficiency with Dryness-Heat is an early pattern in type 2 diabetes, characterized by early-stage β-cell dysfunction, polydipsia, polyuria, dry mouth, and polyphagia. The core pathogenesis is Yin deficiency failing to control Yang, generating dryness-heat, leading to excessive fluid consumption, frequent urination, and hyperglycemia.

Western Mechanism Reference
Early-stage pancreatic β-cell dysfunction causing insufficient insulin secretion, hyperglycemia, and osmotic diuresis leading to polydipsia. Yin Deficiency with Dryness-Heat corresponds to early type 2 diabetes with insulin deficiency and hyperglycemia, where osmotic diuresis and fluid loss contribute to polydipsia and polyuria.
