How safe is Ozempic for achieving your weight loss goals?
These medications can be transformative in the lives of many.

Key takeaways
- Ozempic is a semaglutide medication designed to mimic the GLP-1 hormone, helping to curb appetite, regulate blood sugar, and support significant weight loss when paired with lifestyle changes.
- While Ozempic is generally safe under medical supervision, it may cause side effects like nausea, abdominal pain, or more severe issues like pancreatitis or thyroid cancer, requiring careful monitoring by a healthcare professional.
- For effective and sustainable weight loss, Ozempic works best alongside a holistic approach that includes a balanced diet, regular physical activity, stress management, and behavioural adjustments.
Over the last few years, multiple weight loss medications have been approved worldwide to help address weight-related health conditions such as heart disease and high blood pressure, as well as support people in their weight loss and weight management journeys.
These medications can be transformative in the lives of many who struggle to maintain a healthy body weight, and are prescribed only by medical professionals as a part of a holistic treatment plan.
Ozempic is one of the more well-known weight loss medications. It was approved for use in Canada in 2017. Which begs the question: what is it? And how is it different from other high-profile weight loss medications?
Here, we'll have a look at the nature of Ozempic as a medical treatment, how it helps you to lose weight, and how safe it is to use.
What is Ozempic?
Ozempic is a semaglutide medication, which acts as a glucagon-like peptide-1 receptor agonist (GLP-1). When it’s injected, it makes your body’s own glucagon-like peptide-1 hormone, or GLP-1, work better.
Put a little more simply, GLP-1 is the natural hormone that tells your brain when you’re full. Ozempic works by enhancing that hormonal response, shrinking your appetite, and helping you feel fuller for longer.
GLP-1 also stimulates the body to produce more insulin, the hormone which helps to lower your blood sugar levels, making semaglutides an effective treatment for type 2 diabetes, and as a result, a common ingredient in diabetes medications [2].
Ozempic has traditionally been used for diabetes treatment, but more recently has been prescribed off-label as a weight loss drug, alongside a reduced-calorie diet and an increased exercise program.
It’s taken as a self-administered injection once a week, and has been approved for use in people aged 12 years and older who have at least one weight-related comorbidity, such as hypertension, cardiovascular risk, or cardiovascular disease, and either a body mass index (BMI) of at least 35, or a BMI of 30 to 24.9, provided they meet a criteria established by a Specialist Weight Management Service [3].
Is Ozempic a safe way to lose weight?
When taken under the guidance of a medical professional, Ozempic can be a safe way to lose weight. Numerous clinical trials have shown that with dietary changes, a healthy exercise routine, and behavioural support, Ozempic can help people to reduce their body weight by up to 15% in a year [3].
Ozempic has also been found to regulate appetite, support glycemic control, lower blood pressure, reduce the rate of heart attack, cardiovascular disease and death, and non-fatal stroke [2].
That said, Ozempic can have side effects.
What are the most common side effects of Ozempic?
As with all medications, Ozempic can have some side effects, which range from mild to severe as your body adjusts to the medication.
These tend to be temporary and usually subside as you get used to the medication; however, this depends on your body, genetic background and lifestyle.
Some of the common side effects include:
- Nausea and vomiting
- Diarrhea or constipation
- Abdominal pain
- Gas and bloating
- Heartburn
- Headaches
- Fatigue or dizziness
- Runny nose or sore throat
- Minor allergic reactions
If you experience any of these symptoms, you should speak to your healthcare provider for personalized advice on how to manage your treatment.
The more severe side effects of Ozempic are rarer, but it's worth speaking to your practitioner before taking Ozempic. These side effects can include:
- Pancreatitis
- Hypoglycemia (low blood sugar)
- Gallbladder disease
- Acute kidney failure
- Increased heart rate
- Risk of thyroid cancer
- Severe allergic reaction [2]
If you experience any symptoms of these conditions, you should speak to a medical professional immediately or call 999.
There is also a connection between Ozempic and a possible increased risk of thyroid tumours, including thyroid cancer.
If you have a personal or family history of a type of thyroid cancer called medullary thyroid carcinoma, or if you have an endocrine system condition called Multiple Endocrine Neoplasia syndrome type 2, Ozempic is not safe for you to use [1].
It is also not recommended for pregnant people, people still breastfeeding, or people with kidney disease.
Is Wegovy safer than Ozempic?
Ozempic and Wegovy are both semaglutide medications; however, the key differences between the medications are:
- Wegovy is prescribed at higher doses than Ozempic
- Wegovy is licensed for weight loss treatment in Canada, while Ozempic is primarily licensed to treat diabetes (although it has been prescribed off-label for weight loss treatment)
Although too few studies have been conducted comparing the weight loss medications directly and as such, their safety is generally understood to be about the same, given they feature the same active ingredient [2].
Losing weight with Ozempic
While Ozempic is known to help people lose weight, its efficacy is also dependent on making holistic lifestyle changes that include eating a balanced diet and moving your body more.
Cutting out fatty foods and generally reducing your food intake as you increase your physical activity is vital, as is getting good quality sleep and reducing your stress levels, which should all be incorporated into your treatment plan.

How much weight can you lose in 3 months with Ozempic?
Like with every new medication, Ozempic can take time to work, and how much weight you lose will be dependent on a multitude of factors, including your background, your lifestyle and your day-to-day habits.
A 2022 study did find that people who were overweight or obese lost an average of 5.9% of their overall body weight using Ozempic over 3 months [4], with other studies finding Ozempic also improved cardiovascular outcomes, making it an exciting course of treatment for many.
