If you’re researching weight loss medications, you’ve probably heard about Ozempic. This prescription medication has gained massive attention for its weight loss effects, but not everyone can access it. Understanding the BMI requirements and eligibility criteria is crucial before you book that doctor’s appointment.
What BMI Do You Need to Get Ozempic?
You need a BMI of 30 or higher to qualify for Ozempic for weight loss purposes. If you have weight-related health conditions like type 2 diabetes, high blood pressure, or sleep apnoea, you can qualify with a BMI of 27 or higher.
These aren’t arbitrary numbers. The Therapeutic Goods Administration (TGA) in Australia and similar regulatory bodies worldwide set these thresholds based on extensive research showing that people in these BMI ranges face significant health risks from excess weight. The medication works by mimicking a hormone called GLP-1 that regulates blood sugar and appetite, leading to reduced food intake and weight loss.
How Do You Calculate Your BMI?
BMI stands for Body Mass Index. It’s a simple calculation that uses your height and weight to estimate body fat.
The formula is: BMI = weight in kilograms ÷ (height in metres × height in metres)
Here’s a practical example. If you weigh 90 kilograms and you’re 1.7 metres tall, your calculation would be 90 ÷ (1.7 × 1.7) = 31.1. This BMI would qualify you for Ozempic.
You can also use online BMI calculators that do the maths instantly. Just search “BMI calculator” and enter your measurements.

Understanding where you fall on the BMI scale helps you know your options:
- Underweight: BMI below 18.5
- Normal weight: BMI 18.5 to 24.9
- Overweight: BMI 25 to 29.9
- Obese Class 1: BMI 30 to 34.9
- Obese Class 2: BMI 35 to 39.9
- Obese Class 3: BMI 40 and above
Ozempic prescriptions typically start at the Obese Class 1 category. If you’re in the overweight category with a BMI between 27 and 29.9, you’ll need documented weight-related health conditions to qualify.
What Health Conditions Help You Qualify with a Lower BMI?
Doctors can prescribe Ozempic at a BMI of 27 if you have these conditions:
- Type 2 diabetes
- High blood pressure (hypertension)
- High cholesterol
- Sleep apnoea
- Cardiovascular disease
- Fatty liver disease
- Polycystic ovary syndrome (PCOS)
These conditions significantly increase your health risks when combined with excess weight. Research shows that even modest weight loss of 5 to 10 percent can improve these conditions dramatically. A 2021 study published in the New England Journal of Medicine found that people using semaglutide (the active ingredient in Ozempic) lost an average of 15 percent of their body weight over 68 weeks.
How Much Does Ozempic Cost in Australia?
Ozempic costs vary depending on whether you’re using it for diabetes or weight loss.
For type 2 diabetes patients, Ozempic is listed on the Pharmaceutical Benefits Scheme (PBS). This means you’ll pay around $31.60 per prescription if you have a concession card, or $42.50 if you don’t. The PBS subsidy makes it affordable for people managing diabetes.
For weight loss without diabetes, Ozempic isn’t covered by the PBS. You’ll pay the full private prescription cost, which ranges from $130 to $140 per month. Over a year, that’s roughly $1,560 to $1,680 out of pocket.
Some private health insurance policies may offer partial rebates for weight loss medications, but this varies significantly between providers and policy levels. Check with your insurer directly.
What’s the Difference Between Ozempic and Wegovy?
Both medications contain semaglutide, but they’re approved for different purposes.
Ozempic is approved for type 2 diabetes management. Doctors can prescribe it “off-label” for weight loss, which means using it for a purpose not officially approved by the TGA.
Wegovy is specifically approved for weight loss. It contains higher doses of semaglutide designed for obesity treatment. The eligibility criteria are the same: BMI of 30 or higher, or BMI of 27 or higher with weight-related health conditions.
Wegovy launched in Australia in 2023 but has faced supply shortages. Many people still use Ozempic for weight loss because it’s more readily available.
What Happens During Your Doctor’s Appointment?
Your doctor will assess several factors beyond just your BMI:
- Complete medical history review
- Current medications and supplements
- Previous weight loss attempts
- Blood tests to check kidney function, liver function, and blood sugar levels
- Blood pressure measurement
- Discussion of realistic weight loss goals
Doctors won’t prescribe Ozempic to everyone who meets the BMI criteria. You need to demonstrate that you’ve tried other weight loss methods first. This typically means showing evidence of diet changes, increased physical activity, and possibly working with a dietitian or exercise professional.
The medication works best as part of a comprehensive approach. Studies show that people who combine Ozempic with lifestyle changes lose significantly more weight than those relying on medication alone.
Can You Get Ozempic Online?
Yes, several telehealth services in Australia offer Ozempic prescriptions after online consultations. These services connect you with registered doctors who assess your eligibility through video calls or questionnaires.
Legitimate telehealth providers will:
- Require a proper medical consultation
- Check your BMI and health history
- Order blood tests if needed
- Provide ongoing monitoring
- Issue prescriptions through registered Australian pharmacies
Be cautious of services that promise prescriptions without proper medical assessment. These may not be operating legally and could put your health at risk.
What Are the Side Effects You Should Know About?
Ozempic affects your digestive system, which causes the most common side effects:
- Nausea (reported by 20 to 30 percent of users)
- Diarrhoea
- Constipation
- Vomiting
- Stomach pain
- Reduced appetite
These side effects typically decrease after the first few weeks as your body adjusts. Starting with a lower dose and gradually increasing it helps minimise discomfort.
Serious side effects are rare but include pancreatitis, gallbladder problems, and kidney issues. Your doctor will monitor you regularly to catch any problems early.
How Long Do You Need to Take Ozempic?
Weight loss medications like Ozempic are designed for long-term use. Research shows that most people regain weight when they stop taking the medication.
A 2022 study found that participants regained two-thirds of their lost weight within one year of stopping semaglutide. This happens because the medication changes how your body regulates hunger and fullness. When you stop, those signals return to their previous patterns.
Think of Ozempic as a tool for managing weight long-term, similar to how people with high blood pressure take medication indefinitely. The goal is to reach a healthier weight and maintain it with the medication’s support.
What Results Can You Realistically Expect?
Clinical trials show clear patterns in weight loss results:
- Month 1 to 3: Average loss of 2 to 4 percent of body weight
- Month 4 to 6: Average loss of 6 to 8 percent of body weight
- Month 7 to 12: Average loss of 10 to 15 percent of body weight
For someone weighing 100 kilograms, this means losing 10 to 15 kilograms over a year. Individual results vary based on starting weight, diet quality, physical activity levels, and how your body responds to the medication.
Not everyone loses weight at the same rate. Some people are “super responders” who lose more than 20 percent of their body weight, while others lose less than 5 percent. Your doctor can help adjust your dose or try alternative medications if you’re not seeing results.
Frequently Asked Questions
Can I get Ozempic if my BMI is 29?
No, unless you have weight-related health conditions like type 2 diabetes or high blood pressure. The minimum BMI for Ozempic without health conditions is 30.
Does private health insurance cover Ozempic for weight loss?
Most private health insurance policies don’t cover weight loss medications. Some extras policies may offer small rebates, but you’ll likely pay most of the cost yourself.
How quickly will I lose weight on Ozempic?
Most people start seeing weight loss within the first month, with an average loss of 1 to 2 kilograms. Weight loss continues over 12 to 18 months, with the most significant results appearing after 6 months.
Can I use Ozempic if I’m trying to lose the last 5 kilograms?
No. Ozempic is designed for people with obesity or significant weight-related health risks. It’s not appropriate for people at a healthy weight who want to lose a small amount.
What happens if I miss a dose?
Take the missed dose as soon as you remember, as long as your next scheduled dose is more than 2 days away. If it’s less than 2 days until your next dose, skip the missed one and continue your regular schedule.
Will I need to take Ozempic forever?
Most people need to continue taking Ozempic long-term to maintain their weight loss. Stopping the medication typically leads to weight regain. Discuss your long-term plan with your doctor.
Making Your Decision
What BMI qualifies for Ozempic? The answer is straightforward: you need a BMI of 30 or higher, or a BMI of 27 or higher with weight-related health conditions. These criteria ensure the medication goes to people who will benefit most from its effects.
Before pursuing Ozempic, calculate your BMI accurately and gather information about any weight-related health conditions you have. Book an appointment with your doctor to discuss whether this medication fits your situation. Be prepared to show that you’ve tried other weight loss methods and are committed to making lifestyle changes alongside the medication.
The cost consideration is significant if you’re using Ozempic for weight loss without diabetes. Budget for $130 to $140 monthly, or explore whether Wegovy might be a better option once supply stabilises.
Weight loss medications work best when combined with sustainable changes to your eating habits and physical activity levels. The medication helps control hunger and cravings, but you still need to make choices that support your health goals. Think of Ozempic as a powerful tool in your weight management toolkit, not a magic solution that works on its own.
