GLP-1 + GIP Weight Loss Treatment: What It Is and How It Works

GLP-1 GIP weight loss treatment represents a genuine shift from how weight management medication used to work — not because it’s simply a stronger version of older drugs, but because it targets two separate hormone pathways instead of one. That distinction matters more than the marketing around it usually explains.
At HOP Medical Centre, this treatment sits alongside our broader weight management program as an option for patients who haven’t achieved lasting results through diet and exercise alone. This guide explains what GLP-1 + GIP therapy actually does, what results look like in practice, and what a medically supervised program involves.
How GLP-1 + GIP Therapy Actually Works
GLP-1 + GIP therapy is a prescription treatment that mimics two naturally occurring hormones involved in appetite and metabolic regulation. Earlier GLP-1-only treatments target a single appetite-regulating pathway. GLP-1 + GIP treatments target two pathways simultaneously, which helps regulate hunger, increase feelings of fullness, and support weight management more comprehensively than a single-hormone approach.
In practical terms, this means less constant hunger and a stronger, faster sense of fullness after eating — the two factors that make sustained calorie reduction difficult to maintain through willpower alone.
What Results Actually Look Like
Clinical data shows meaningful results for many participants: up to 4 in 10 participants on GLP-1 + GIP achieved at least 25% body weight loss. This is a substantial number, but it’s worth reading carefully — it also means a majority of participants see results below that threshold, and individual response varies based on starting weight, adherence, and other health factors.
| Factor | What to Know |
|---|---|
| Mechanism | Dual GLP-1 + GIP receptor agonist, mimicking two appetite hormones |
| Administration | Injectable, typically weekly |
| Reported outcome | Up to 4 in 10 participants achieved ≥25% body weight loss |
| Cost at HOP Medical Centre | From S$15.90/day (excl. GST) |
Who This Treatment Is For
GLP-1 + GIP therapy is prescription-only and requires medical assessment before starting, not a treatment someone opts into independently. It’s generally considered for adults who haven’t achieved sustained results through diet and exercise alone, particularly where weight is affecting broader health markers like blood pressure, cholesterol, or blood sugar.
- Your weight history and previous attempts at weight management
- Relevant medical history, including thyroid and pancreatic conditions
- Current medications and potential interactions
- Realistic expectations for your specific starting point
- A monitoring plan for the duration of treatment
What to Expect During Treatment
Treatment is administered by injection, typically on a weekly schedule, alongside ongoing medical supervision rather than as a one-time prescription. Like most GLP-1-class medications, common side effects can include nausea, digestive changes, and appetite suppression, particularly during the initial dose-adjustment period. These effects often ease as the body adjusts, though your care team monitors this throughout.
This isn’t a standalone solution independent of lifestyle changes. Most medically supervised programs, including HOP’s, pair the medication with nutritional and activity guidance to support results that last beyond the treatment period itself.

Results vary by individual. Clinical data shows up to 4 in 10 participants achieved at least 25% body weight loss, though outcomes depend on adherence and individual factors.
3. Is this treatment safe?
It’s a prescription medication requiring medical assessment and ongoing supervision. Your doctor will review your medical history to confirm suitability before starting.
4. How is the medication administered?
