Weight Management

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.

Common questions
Wegovy vs Saxenda — what's the difference?+
Both are GLP-1 receptor agonists but with different active ingredients and dosing. Wegovy uses semaglutide (once-weekly injection, FDA-approved 2021 for weight management). Saxenda uses liraglutide (once-daily injection, FDA-approved 2014). Wegovy generally produces slightly higher average weight loss (~15% vs ~8%) but Saxenda has a longer real-world safety track record. Your physician will recommend based on your medical history, lifestyle, and insurance / payment preference.
Are there side effects?+
Most common are mild GI symptoms in the first 4-8 weeks — nausea, constipation, occasional diarrhea — which usually resolve as the body adapts. Rare but serious: pancreatitis, gallbladder issues, kidney problems. We screen for contraindications (personal/family history of medullary thyroid carcinoma, MEN-2 syndrome, severe GI disease) before prescribing. Monthly reviews catch any emerging issue early.
Will I gain the weight back when I stop?+
Without lifestyle changes, most patients regain 50-70% of lost weight within 1-2 years of stopping. This is why we pair every pen program with nutrition coaching and exercise guidance. Some patients continue at a lower maintenance dose long-term; others transition off completely once habits are established. We discuss the exit strategy at the 6-month review.
