Weight loss injections have become so popular that they are now mentioned by Hollywood celebrities and dubbed “skinny jabs”.
With all this attention, you might be wondering just what these injections are and how they work. To help you with this, we’ve outlined the biological mechanisms behind the injections and what you should consider before getting them.
What Are Weight Loss Injections?
Weight loss injections are a category of prescription drugs that belong to a class of drugs known as glucagon-like peptide-1 (GLP-1) receptor agonists.
An example is liraglutide a once-daily injection that is taken subcutaneously (under the skin). It works by mimicking the effects of GLP-1, a hormone that regulates appetite and metabolism.
Another example is semaglutide a once-weekly GLP-1 receptor agonist injection taken subcutaneously. It is important to note that other than weight loss, liraglutide and semaglutide may also be used in the treatment of diabetes for some people.
How Do Weight Loss Injections Work?
When you’re eating,The GLP-1 hormone helps to signal your brain when the stomach is full. GLP-1 hormones also help to slow down the speed at which the food moves through your stomach, which makes you feel full for longer. This action makes you eat less, potentially leading to weight loss.
Now, GLP-1-based weight loss injections are helpers that increase the levels of this messenger (GLP-1) in your body, making it easier for your brain to know when you’re full. This leads to a reduction in hunger and increased feelings of fullness, so you eat less, and over time, this can result in weight loss.
In terms of how GLP-1-based weight loss injections work, they are taken subcutaneously (under the skin) and work by mimicking the effects of GLP-1 in the body. GLP-1 is a hormone naturally produced in the small intestine and regulates appetite and metabolism.
When you eat a meal, GLP-1 is released into the bloodstream and signals to the brain that you’re full, reducing hunger and promoting feelings of fullness. GLP-1 also slows down the rate at which food moves through the stomach, which helps you feel full for longer.
By increasing the levels of GLP-1 in the body, GLP-1-based weight loss injections help to reduce hunger and increase feelings of fullness, leading to decreased food intake and weight loss. It’s important to note that these medications are not a permanent solution for weight loss and need to be taken regularly to maintain their effects.
Additionally, they should be used in combination with a reduced-calorie diet and increased physical activity to achieve and maintain weight loss.
These injections are not a silver bullet for weight loss and require a healthy diet and physical activity. They may also come with mild but manageable side effects such as nausea or headache , so it’s always best to consult an experienced doctor before using them.
How Long Do Weight Loss Injections Last?
The duration of the effects of weight loss injections vary depending on the specific medication and the individual’s response to it.
For example, liraglutide is a once-daily injection taken subcutaneously (under the skin). The effects of a single dose of liraglutide can last for up to 13 hours. Semaglutide is a once-weekly GLP-1 receptor agonist injection taken subcutaneously, too. The effects of a single dosecan last for up to 7 days
It is also dependent on the dosage prescribed by your doctor. Typically the dosage will start small and gradually be increased as the body get used to the medication.
