Metformin's primary side effect is gastrointestinal upset, including diarrhea and abdominal discomfort

GLP-1 Life Cycle: Precision in Biological Control The GLP-1 life cycle: a lesson in biological precision From gene expression to signal shutdown, native GLP-1 is designed to deliver fast, glucose-dependent metabolic control, then disappear: Originates from the GCG (preproglucagon) gene, with tissue-specific processing Produced in intestinal L-cells via PCSK1/3, not pancreatic pathways Secreted after meals through SGLT1-driven glucose sensing and Ca-dependent release Acts via GLP-1 receptors cAMP PKA & Epac, amplifying insulin only when glucose is elevated ~75% is degraded locally in the gutliver axis Only ~1015% reaches systemic circulation intact Half-life: ~12 minutes, terminated by DPP-4 and renal clearance This tightly regulated signal burst shutdown explains: why GLP-1 is powerful but safe why glucose gating matters why pharmacology had to extend a naturally short signal GLP-1 isnt a long-acting hormone
