Common questions

FAQs: weight loss clinic in Perth

Who is the best weight loss clinic in Perth?

How quickly can I get a quote in Perth?

Most weight loss clinics in Perth respond to quote requests within 24 hours, and many within the same business day. Submitting your requirements once through a comparison service like Compare Weight Loss Clinics returns up to 3 quotes in under a minute.

How are GLP-1 weight-loss medicines accessed in Australia?

Any GLP-1 receptor agonist used for weight management is a prescription-only (Schedule 4) medicine and requires a prescription from an AHPRA-registered doctor, who decides whether it is clinically appropriate. They are generally not PBS-subsidised for weight loss, so they are paid privately. This is general information, not a recommendation or an offer to supply; discuss suitability, risks and cost with your own doctor.

What outcome ranges have been studied for GLP-1 medicines?

Published clinical-trial programmes for TGA-approved GLP-1 medicines (STEP for semaglutide, SURMOUNT for tirzepatide) report ranges of average weight change over set durations. The TGA Product Information for each medicine is the source of truth for indications, dosing and trial data. Real-world results vary by patient and may differ from trial averages. Discuss expected outcomes with your prescriber, not a comparison website.

What side effects are listed for GLP-1 medicines?

TGA Consumer Medicine Information (CMI) for each GLP-1 medicine lists the full side-effect profile, contraindications and warnings. Common side effects reported across trials include gastrointestinal symptoms during titration. Less common but serious risks are listed in the CMI. Search for the CMI for the specific medicine at tga.gov.au and discuss any concerns with your prescriber.

How do bariatric surgery and GLP-1 medication compare as weight-management options?

Both bariatric surgery and TGA-approved GLP-1 medicines are weight-management options used in Australia, with different indications, costs, side-effect profiles and recovery timelines. Eligibility for either is set by your treating clinician based on current Australian guidelines. We do not recommend a pathway. Your GP or an obesity-medicine specialist will discuss which option (if any) is appropriate for your circumstances, including risks, benefits, costs and long-term plan.

How much does bariatric surgery cost in Australia?

Gastric sleeve $18-25k, gastric bypass $20-30k all-inclusive in private hospitals. Private health insurance with appropriate hospital cover typically pays $5-10k of this, leaving $8-18k out-of-pocket. Public hospital bariatric surgery exists in some states for BMI 40+ but waitlists are 2-5 years. Cost includes surgeon, anaesthetist, hospital, and usually post-op follow-up. Doesn't include pre-op dietitian/psych assessments ($1,000-$2,500).
