Semaglutide is a relatively new drug that has been shown to be just as effective at reducing body weight as certain weight loss surgeries. The drug’s effects were uncovered during a clinical trial led by Professor Rachel Batterham at University College London (UCL) to evaluate the efficacy of this drug in weight management.
The trial consisted of nearly 2000 people, across multiple countries. Each participant was either given a 2.4mg dose of semaglutide or a placebo on a weekly basis. They were also provided with counselling sessions from dietitians to help them stick to a reduced-calorie diet and exercise more.
The study reported an average weight loss of around 2.4 stone or 15.3kg was lost in the group of participants taking the drug, while those receiving the placebo (dummy drug) only lost an average of 0.4 stone or 2.6kg.
Moreover, within the group taking Semaglutide, 75% of those in the Semaglutide group lost over 10% of their body weight and more than 30% lost over 20% of their body weight. The findings indicate that this may indeed represent a major breakthrough in improving the health of those living with obesity.
Something you may be wondering is how this new drug may work to assist with weight management.
Semaglutide is something called a GLP-1 (or glucagon-like peptide-1) agonist.
This means that it binds to the GLP-1 receptor in the brain and increases its activity, which has a number of favourable downstream effects. For instance, when activated, this receptor can trigger an increase in hormones called ‘incretins’, which work to:
The first thing to be aware of is that you may know Semaglutide by its trade name – Ozempic.
With respect to dosage, the National Institute for Healthcare and Excellence (NICE) recommends 0.25mg once a week for 4 weeks. This can then be followed by 0.5mg once a week for at least 4 weeks and then increased to 1mg a week if necessary.
These recommendations may differ between individuals and between different administration methods. Speaking to your regular healthcare provider for further information is always best.
As with any medical therapy, there are some potential side effects that users can experience.
Side effects that are most common can include:
Other less common side effects that can be experienced may include pancreatitis and altered taste. If you begin to note symptoms of acute pancreatitis, such as severe abdominal pain, you should stop taking the medication.
If symptoms persist or become severe, it is crucial that you reach out to your healthcare provider for further assistance.
Different medications can also interact and impact each other’s function or endanger your health. If one medication may negatively impact another, this is referred to as a contraindication.
For instance, there have been reports of diabetic ketoacidosis in patients with type 2 diabetes when taking GLP-1 receptor agonists alongside insulin.
Hence, it is incredibly important that you seek further guidance on if Semaglutide is an appropriate and safe medication for you by speaking with your doctor.
You can find more information regarding the contraindications and adverse effects of Semaglutide via the NICE website, but this does not replace a conversation with your doctor.
There is also guidance that Semaglutide may not be appropriate for those who are pregnant, breastfeeding or have existing liver or kidney impairment.
One semaglutide pen contains 4 x once weekly doses of semaglutide and costs £73.25.
The social media platform TikTok has been at the centre of a number of controversies where semaglutide is marketed to people without type 2 diabetes or obesity as a quick-fix weight loss drug:
Semaglutide is a promising and safe medication that is accessible to certain patients through their doctor.
Due to the mechanism of action, this drug may elicit significant weight loss, though there are a number of side effects to be aware of.
