That stress disrupts the hair growth cycle, pushing more hairs into the shedding (telogen) phase while fewer new ones grow in
GLP-1 Key Research Facts Full name: Glucagon-Like Peptide-1 incretin hormone of the proglucagon family Primary bioactive form: GLP-1(736)amide 30 amino acids, C-terminally amidated Gene source: Proglucagon gene processed by PCSK1 in intestinal L-cells and brainstem NTS neurons In vivo half-life: Approximately 12 minutes rapidly inactivated by DPP-4 (cleaves His7-Ala8 dipeptide) Primary receptor: GLP-1R (GLP-1 receptor) class B G protein-coupled receptor (GPCR) Signalling: GLP-1R activation cAMP elevation PKA/CREB activation glucose-dependent insulin secretion Additional signalling: PI3K/Akt pathway -cell survival, proliferation, and glucose sensitivity Secretion pattern: Biphasic post-meal release from intestinal L-cells early neural/endocrine peak + late direct nutrient-contact peak Fasting plasma level: ~510 pmol/L
For many patients, ongoing use is recommended to sustain results
Complementary mechanisms include increasing pancreatic -cell proliferation and reduces glucagon release which also contribute to an overall reduction in appetite
Notably, phentermine was one of the ingredients in fen-phen (fenfluramine/phentermine), a drug that researchers linked to serious valvular heart problems in the 1990s
