GLP-1 receptor agonists work by: Enhancing insulin secretion from pancreatic beta cells in a glucose-dependent manner, which helps lower blood glucose levels without causing excessive hypoglycaemia Suppressing glucagon release from alpha cells, reducing hepatic glucose production Slowing gastric emptying , which prolongs the feeling of fullness after meals Acting on appetite centres in the brain , particularly the hypothalamus, to reduce hunger and food intake These medications are administered via subcutaneous injection, typically once weekly or once daily depending on the specific formulation
DES has the opposite a tripeptide deletion at the N-terminus that also reduces IGFBP binding but with different receptor-affinity profile and shorter half-life
Dose adjustment considerations: If gastrointestinal symptoms are severe or persistent despite these measures, contact your prescribing clinician to discuss: Slowing the dose escalation schedule Temporarily reducing the dose Taking a brief treatment pause (though this may affect weight loss progress) Switching to an alternative weight management medication if symptoms are intolerable The STEP trials demonstrated that slower dose titration can reduce the incidence and severity of gastrointestinal adverse effects
The enhancing effects of LC or LCLN on semen quality and serum hormonal profile is mainly attributed to their antioxidant and androgenic properties 92
The critical need for production of NADPH, via the pentose phosphate pathway, is especially true in red blood cells because there are no other NADPH-producing reactions in these cells and they are extremely sensitive to oxidative damage
