Weight-Loss Pen (Wegovy / Saxenda)
Physician-supervised GLP-1 pen program — 10-15% body-weight loss over 6-12 months
- What is Weight?
- The Weight-Loss Pen program at Waleerat Clinic uses GLP-1 receptor agonists — semaglutide (Wegovy) or liraglutide (Saxenda) — delivered via self-administered subcutaneous pen injection. These peptides mimic the body's natural GLP-1 hormone to suppress appetite, slow gastric emptying, and improve insulin sensitivity. Typical weight loss is 10-15% of body weight over a 6-12 month physician-supervised program.

Weight-Loss Pen is a physician-supervised injectable program using GLP-1 receptor agonists (Wegovy / Saxenda). After a metabolic screening and BMI assessment, patients self-administer a once-weekly (semaglutide) or once-daily (liraglutide) pen injection at home.
Monthly clinic visits include weight tracking, side-effect review, and dose adjustment. Typical outcomes: 10-15% body-weight reduction over 6-12 months, plus improved waist circumference, blood pressure, and lipid markers.
Program includes nutrition guidance and is best paired with a lifestyle plan.
