Biguanide boss that tells the liver to calm down
Acronym
BHS — Bedazzled Hedgehogs Snore.
Story
A loud factory keeps belching out glucose. Metformin walks in, turns down the smokestacks, and the whole town’s sugar supply calms down.
Connect the pieces
- B (Bedazzled) → Biguanide: Metformin is the classic biguanide used in type 2 diabetes.
- H (Hedgehogs) → Hepatic: Lowers hepatic glucose production.
- S (Snore) → Sensitivity: Improves insulin sensitivity, making it a foundational type 2 diabetes therapy when appropriate.
- Bedazzled · Biguanide: Metformin is the classic biguanide used in type 2 diabetes.
- Hedgehogs · Hepatic: Lowers hepatic glucose production.
- Snore · Sensitivity: Improves insulin sensitivity, making it a foundational type 2 diabetes therapy when appropriate.
Know the limits
It is used for type 2 diabetes, not as a substitute for insulin in type 1 diabetes.
