Wegovy is a once-weekly prescription medicine that has changed the conversation around medical weight management. For some people, it can reduce appetite and make sustained changes to eating habits feel more achievable. For others, it may not be suitable, or the side effects and cost may outweigh the benefits. A GP assessment is the right place to start.
What is Wegovy and how does it work?
Wegovy contains semaglutide, a medicine that mimics a naturally occurring hormone called GLP-1. This hormone helps regulate appetite and can slow the movement of food through the stomach. Many people feel fuller sooner, stay full for longer and experience fewer food cravings.
It is given as an injection under the skin once a week, usually in the stomach, thigh or upper arm. Treatment normally begins at a low dose, then increases gradually over time. This stepped approach is designed to help your body adjust and reduce the chance of troublesome stomach-related side effects.
Wegovy is not a replacement for food, movement, sleep or support with behaviour change. It is prescribed as part of a broader weight-management plan. The medicine may help create the breathing room needed to build habits that can be maintained over the longer term.
Who may be suitable for Wegovy?
Whether Wegovy is appropriate depends on your health history, current weight, other medicines and treatment goals. In Australia, GPs commonly consider prescription weight-management medicines for adults living with obesity, or for people who are overweight and have weight-related health concerns such as high blood pressure, type 2 diabetes, sleep apnoea or high cholesterol.
A number on the scales alone does not tell the whole story. Your GP will also consider factors such as your waist measurement, family history, previous attempts at weight loss, eating patterns, activity levels and any barriers affecting your health. Weight gain can be influenced by medications, hormonal changes, stress, poor sleep and medical conditions, so a proper review matters.
Wegovy may not be appropriate if you are pregnant, breastfeeding or planning a pregnancy. It may also be unsuitable for people with certain medical histories, including particular thyroid conditions, or those who have had pancreatitis. Semaglutide should generally be stopped well before a planned pregnancy, so speak with your GP early if your circumstances change.
Your doctor also needs to know about every medicine and supplement you take. This includes diabetes medicines, as combining treatments can affect blood glucose levels and may require closer monitoring.
Starting Wegovy: what to expect
If a GP decides Wegovy may be suitable, they will explain how to use the injection device, how often to take it and what to do if you miss a dose. The dose is increased in stages rather than all at once. Following the prescribed schedule is safer than trying to move up quickly.
Some people notice a reduced appetite within the first few weeks. Weight changes, however, vary considerably. A realistic plan focuses on more than rapid results. It should include regular meals with enough protein and fibre, enjoyable forms of movement, adequate sleep and a plan for stressful periods when routines are harder to keep.
Follow-up appointments are a valuable part of treatment. They give you and your GP an opportunity to check progress, manage side effects, review blood pressure or pathology where needed, and decide whether the medicine is still providing enough benefit. If it is not helping, or it is making you feel unwell, another approach may be better.
Wegovy side effects and when to seek help
The most common side effects are nausea, vomiting, diarrhoea, constipation, stomach pain, indigestion and headache. These effects are often most noticeable when beginning treatment or increasing the dose. Eating smaller meals, stopping when you feel comfortably full and choosing less fatty foods can help some people manage nausea.
Do not ignore severe or persistent symptoms. Contact a doctor promptly if you have ongoing vomiting, cannot keep fluids down, severe stomach pain, signs of dehydration or symptoms that concern you. Severe pain in the upper abdomen, particularly if it spreads to the back, needs urgent medical assessment as it can be a sign of pancreatitis. Sudden severe allergic symptoms, chest pain or difficulty breathing require urgent care.
It is also worth discussing changes in mood or eating behaviours with your GP. Weight management should support your overall wellbeing, not make food, body image or daily life more distressing.
Can a telehealth GP help with Wegovy?
For many adults, an Australian-registered GP can begin a weight-management discussion by phone or video consultation. This can be useful when work, family commitments, travel or distance make it difficult to get to a clinic. Come prepared with your current weight, height, relevant medical history, medication list and any recent test results you have access to.
A telehealth consultation does not automatically mean a prescription is appropriate. Your GP may request blood tests, ask for regular measurements, recommend an in-person examination or refer you to another clinician before making a decision. That is good clinical care, not an unnecessary delay.
If clinically appropriate, TeleDoc can connect you with an Australian-registered GP for a private, confidential consultation from your mobile or computer. The doctor can discuss your options, including whether Wegovy may be worth considering and what monitoring would be needed. No responsible service should promise a particular medicine before assessing you.
Common questions about Wegovy
Is Wegovy the same as Ozempic?
Both medicines contain semaglutide, but they are approved and supplied for different purposes and may have different dosing schedules. Ozempic is primarily used in type 2 diabetes management, while Wegovy is specifically used for chronic weight management. Your GP can explain which treatment, if any, is appropriate for your circumstances.
Do you need to take Wegovy forever?
It depends. Obesity is often a long-term health condition, and appetite or weight may increase again after stopping treatment. Some people remain on medicine longer term, while others stop because of side effects, cost, pregnancy plans, changing health needs or because another strategy is more suitable. This decision should be reviewed with your GP rather than made abruptly.
What happens if you miss a dose?
The correct action depends on how long it has been since your scheduled injection and where you are in your dosing schedule. Check the medicine information and ask your pharmacist or GP for advice. Do not double up a dose to catch up.
Can Wegovy be prescribed without an appointment?
No. Wegovy is a prescription medicine and requires a clinician to assess whether it is suitable and safe. A consultation also gives you the chance to discuss side effects, interactions, expected outcomes and follow-up care.
The most useful next step is a straightforward conversation with a GP who will look at the full picture, not just the number on the scales. The right plan should be practical for your life, safe for your health and supported well enough to give you a genuine chance of maintaining progress.
