How do Weight Loss Injections (Mounjaro and Wegovy) Work?

In recent years, weight loss injections have become one of the most effective and talked-about treatments for managing obesity and improving overall health. Among the most popular in the UK are Mounjaro and Wegovy - both available through iQ Doctor.

But how exactly do these injections work, and what makes them so effective? Let’s explore the science behind them, their benefits, and how they differ from traditional weight loss methods.

What Are Weight Loss Injections?

Weight loss injections like Mounjaro and Wegovy are prescription medications designed to help adults with obesity or weight-related health issues lose weight safely. They are typically used alongside a balanced diet and regular physical activity.

Unlike over-the-counter supplements, these injections target specific hormones in the body that regulate appetite, blood sugar levels, and metabolism.

How Do Weight Loss Injections Work?

Both Mounjaro and Wegovy belong to a class of medicines known as GLP-1 receptor agonists, which mimic the effects of a natural hormone called glucagon-like peptide-1 (GLP-1). This hormone is released in the gut after eating and helps control hunger and blood sugar levels.

Here’s how these injections work in the body:

• Reduce Appetite: They slow down digestion and signal to your brain that you feel full, helping to reduce calorie intake naturally.
• Regulate Blood Sugar Levels: They help the body release insulin more effectively, stabilising blood sugar and reducing cravings for sugary foods.
• Improve Metabolic Function: By mimicking natural hormones, they help the body use energy more efficiently and reduce fat storage.
• Sustain Long-Term Weight Loss: With consistent use and lifestyle changes, many users experience gradual, sustainable weight loss over several months.

Mounjaro vs Wegovy: What’s the Difference?

Mounjaro may offer additional benefits as it targets two hormones (GLP-1 and GIP), potentially leading to even greater appetite suppression and fat loss.

Are Weight Loss Injections Safe?

When prescribed and monitored by a qualified healthcare provider, Mounjaro and Wegovy are considered safe and effective. However, as with all medications, they can have side effects such as nausea, constipation, or mild stomach discomfort, especially during the first few weeks.

To ensure safety, always consult a registered healthcare professional - such as those at iQ Doctor - before starting treatment.
