Hormonal

Orforglipron, an oral non-peptide GLP-1 receptor agonist, produces dose-dependent reductions in body weight (up to 9.8% at 45 mg) and waist circumference, with maximal efficacy observed at higher doses (24-45 mg).

Orforglipron is an oral medication that helps obese adults lose weight and improve metabolic markers like blood sugar and cholesterol. It works by mimicking a natural hormone (GLP-1) to reduce appetite and slow digestion. The higher the dose (up to 45 mg daily), the more weight is lost, with studies showing up to 9.8% body weight reduction. However, higher doses also increase the risk of stomach issues like nausea and diarrhea, which may lead some patients to stop taking it. It is taken once daily without strict fasting requirements, making it more convenient than some injectable alternatives.
