Hormonal
Pharmacotherapy using GLP-1 receptor agonists (semaglutide) or dual GIP/GLP-1 agonists (tirzepatide) produces significant weight loss (10-20%) and improves obesity-related comorbidities, serving as a necessary adjunct to lifestyle intervention for patients with BMI ≥30 kg/m2 or ≥27 kg/m2 with complications.
If you have a BMI over 30 (or over 27 with health issues like high blood pressure or diabetes), lifestyle changes alone often aren't enough because your body fights weight loss. Medications like semaglutide or tirzepatide, taken once weekly, can help you lose 10-20% of your body weight and improve your health conditions. These are long-term treatments; stopping them usually leads to regaining the weight. If cost is a barrier, ask your doctor about starting at a lower dose, which may still be effective.
Pharmacotherapy is indicated as an adjunct for those living with obesity (body mass index [BMI] ≥30 kg/m2) or those who are overweight (BMI ≥27 kg/m2) with a least one weight-related complication... Weight loss of 5–15% has been shown to improve and/or prevent progression of obesity-related comorbidities.
