Let’s get into it!
Ozempic, also known by the brand names Wegovy or Rybelsus, is a medication that was developed in 2012 by the pharmaceutical company Novo Nordisk. You may have also heard of another drug option called Saxenda, but the active ingredient in this is liraglutide, not semaglutide.
The active ingredient in Ozempic is semaglutide, which is in the glucagon-like peptide-1 (GLP-1) receptor agonist class. It is able to aid in the treatments of type-2 diabetes, chronic obesity, and other weight-related conditions.
Ozempic is used primarily for people with type-2 diabetes, but it has also been approved by Health Canada for the treatment of those with a body mass index (BMI) of 27 or higher. When used for weight management, it should be used alongside lifestyle changes, which include implementation of a healthy diet and regular exercise.
Additionally, Ozempic can provide a range of benefits, such as blood glucose control, increased insulin production, and improved cardiovascular health. The GLP-1 hormone is in charge of a whole range of functions within the body, such as increasing insulin production in the pancreas, controlling blood glucose levels in the liver, and aiding in satiety and appetite suppression in the brain, among many others.
By replicating the effects of this hormone, semaglutide is able to provide all of these benefits at an increased rate.
How Does Ozempic Work?
Semaglutide, the active ingredient and GLP-1 receptor agonist in Ozempic, is able to mimic the GLP-1 hormone. This is the hormone that is generally released in the gut after food has been consumed.
The GLP-1 hormone is in charge of a whole range of functions within the body, such as increasing insulin production in the pancreas, controlling blood glucose levels in the liver, and aiding in satiety and appetite suppression in the brain, among many others. By replicating the effects of this hormone, semaglutide is able to provide all of these benefits at an increased rate.
Ozempic is a medication that is used to treat chronic conditions, meaning it is suitable for long-term use and can be taken indefinitely. In fact, Ozempic needs to be taken consistently in order for it to work correctly.
Coming off this medication suddenly may result in spikes in blood sugar levels or weight gain, and should be done with caution.
That being said, Ozempic is still a relatively new medication and not all of the details on long-term efficacy and side effects are known for certain.
While most studies show that participants using Ozempic were able to use it effectively as a tool for weight management for at least two years, research and clinical trials beyond this are still being conducted.
If you have any concerns about your use of Ozempic, consult with your medical team for more advice and to discuss your suitability for the drug.
Ozempic is increasingly being used for weight management due to the range of effects that it has on the body.
Being a GLP-1 receptor agonist means that Ozempic is able to activate several pathways that assist greatly with weight management, especially when paired with exercise and a balanced diet.
Ozempic Delays Gastric Emptying
One of the effects that Ozempic can have on the body is a slight delay in gastric emptying. This is able to reduce the rate at which glucose appears in circulations and causes food to linger in your stomach for longer.
Delayed gastric emptying is often viewed negatively due to the fact that it can cause unintentional weight loss, but for those aiming to improve their weight management, this may be a great help in their journey.
Ozempic Reduces Hunger and Appetite
An extremely noticeable effect that Ozempic can have when it comes to weight loss is a reduction in hunger and appetite. It does this by targeting the hunger receptors in the brain and meaning that those taking the drug may feel more full after meals.
This is one of the roles of the GLP-1 hormone that Ozempic is able to mimic. By doing so, those taking the medication may notice that their appetite has decreased significantly, leading to a caloric deficit.
By reducing hunger, Ozempic can often lead to a change in diet and a decrease in emotional eating, snacking, and binge eating.
Ozempic Increases Satiety and Prevents Overeating
Overeating is another issue that contributes to weight gain that Ozempic is able to assist with. The medication is able to increase satiety, or the sensation of being satisfied, which can in turn prevent overeating. This can often enable patients to stick to diet plans without feeling hungry or deprived of food during the process, and can also eliminate subconscious snacking and overeating.
Understanding the Clinical Evidence
Research has been done in a variety of different areas regarding the way that Ozempic functions, such as the health risks, the benefits, and how effective this drug is in aiding different conditions.
Although no research from an extensive, long-term clinical study of Ozempic has been published yet, this drug is still being examined, and new information released.
That being said, the information we have from clinical trials that have already been conducted shed some light on how effective Ozempic can be.
Results of the SUSTAIN 6 Clinical Trial
The SUSTAIN 6 clinical trial of semaglutide, the active ingredient in Ozempic, was a trial that selected 3,297 type-2 diabetes patients to be put on a weekly injection that contained either semaglutide or a placebo.
What the results of this trial indicated is that semaglutide was successful in significantly reducing the risk of cardiovascular health problems.
Eventually, Ozempic was approved as a medication that is able to reduce cardiovascular related incidents in patients who suffer from type 2-diabetes and heart disease.
Studies Showing Long-term Effectiveness of Ozempic
Although the research of long-term clinical trials have not yet become publicly available due to the fact that Ozempic is still a relatively new medication, there are still some trials that span a significant length of time that suggest Ozempic is effective in the long-term.
The aforementioned SUSTAIN 6 trial spanned two years and displayed significant reduction in the risk of cardiovascular incidents in the long-term.
In another two year long trial, it was observed that Ozempic was able to result in significant weight loss in the long-term, with an average weight loss of >20% being observed at week 104 of the trial.
Both of these clinical trials indicate that Ozempic is able to remain effective during testing periods of at least two years, though it is likely that more extensive trials will become available in the future.
What Are the Side Effects and Contraindications?
Along with any medication comes some side effects and contraindications to watch out for, and Ozempic is no exception.
While the side effects that do come along with Ozempic are not known to be particularly harsh or long lasting, it is still important to be aware of them and consult your medical team if necessary.
It is also extremely important to be aware of the contraindications of Ozempic, as ignoring these guidelines could result in severe health complications.
