Exploring weight loss injections: Are they right for you?

Weight loss can be challenging for many individuals, particularly when diet and exercise alone do not yield the desired results. In recent years, weight loss injections have emerged as an option for those seeking additional support in managing their weight. But what are these injections, and how do they work? We speak to a leading GP who addresses common questions and provide key insights into this medical approach.

What are weight loss injections?

Weight loss injections typically involve medications designed to help individuals manage their weight by influencing appetite or metabolism. One commonly prescribed class of medications is GLP-1 receptor agonists, such as liraglutide (Saxenda) or semaglutide (Wegovy). These medications mimic a hormone called GLP-1, which helps regulate appetite and blood sugar levels. Essentially, they work by making you feel full sooner and reducing hunger, which can lead to lower calorie intake over time.

It’s important to note that weight loss injections are not a "magic fix." They are part of a broader treatment plan that includes a healthy diet and regular physical activity.

Who might benefit from weight loss injections?

Weight loss injections are typically prescribed for individuals with a body mass index (BMI) of 30 or higher, which falls into the category of obesity, or for those with a BMI of 27 or higher if they have weight-related health conditions such as type 2 diabetes or high blood pressure.

Medical professionals carefully evaluate whether these treatments are suitable based on an individual’s medical history, current medications, and lifestyle. Weight loss injections are generally recommended when other methods, such as dietary changes and exercise, have not been sufficiently effective.

Are weight loss injections safe?

Safety is a top priority, and weight loss injections are rigorously tested in clinical trials before approval. Like any medication, they may have side effects. Common side effects include nausea, diarrhoea, or constipation, which often improve as your body adjusts. Rare but serious risks, such as pancreatitis (inflammation of the pancreas), have been reported, so ongoing medical supervision is essential.

Your healthcare provider will discuss the risks and benefits of these medications in detail, ensuring that the potential advantages outweigh any concerns for your specific situation.

How are these injections administered?

Weight loss injections are usually self-administered under the guidance of a doctor. Patients are taught how to inject the medication, often into the abdomen, thigh, or upper arm, using a prefilled pen. The injections are typically given daily or weekly, depending on the specific medication prescribed.

Regular follow-up appointments are crucial to monitor progress, adjust dosages, and address any side effects. Weight loss with these injections tends to be gradual, with many patients seeing the most significant results after several months of consistent use.

Could weight loss injections be right for you?

If you’ve struggled with weight loss despite your best efforts, weight loss injections might offer a valuable tool to support your journey. Consult your doctor to explore whether this treatment aligns with your goals and overall health.
