What the research says, what to expect – and what alternatives exist

Injectable medications like Ozempic, Wegovy, and Mounjaro are gaining attention as modern tools for weight loss. Social media is filled with before-and-after photos, success stories, and promises of rapid results – creating the impression that injections may finally be the answer to excess weight.

But is it really that simple?
In this article, we explore how these medications work, what results you can expect, who they’re suitable for – and what scientifically proven alternatives are available for those seeking long-term change.

How Do Weight Loss Injections Work?

Ozempic, Wegovy and Mounjaro all belong to a class of medications known as GLP-1 receptor agonists. They mimic a hormone that helps regulate appetite and blood sugar levels, making you feel fuller and reducing your food intake.

• Ozempic was originally developed to treat type 2 diabetes. Weight loss is a secondary effect, with most users losing around 6–7% of their body weight.
  
  
• Wegovy, which uses the same active ingredient, is licensed specifically for weight management, often leading to an average 15% weight loss.
  
  
• Mounjaro (tirzepatide) is a newer dual-action medication. Clinical trials have shown patients losing 20% or more of their body weight – the most significant results to date.
  
  

Impressive? Yes. But it’s important to look beyond the headlines.

Effectiveness: What the Data Shows

Results often appear within 2–3 months. However, to achieve the full effect, long-term use is required – usually six months or more. And after stopping treatment, many people experience weight regain.

Side Effects: What You Should Be Aware Of

Weight loss injections can trigger a range of side effects, particularly during the initial stages of treatment:

• Nausea and vomiting
• Abdominal pain, constipation, or diarrhoea
• Fatigue, dizziness, and headaches
• Changes in taste or reduced appetite
• Digestive issues or bloating
  
  

For some, these symptoms fade over time. For others, they become a reason to discontinue treatment altogether.

Also important to note:

• These medications are not safe during pregnancy or breastfeeding.
• They must be used with caution if you’re taking other medications, especially for diabetes or digestive disorders.
• Some users report increased anxiety or emotional shifts related to eating behaviour.
  
  

Is There an Alternative? When Injections Might Not Be Enough

Yes, injections can help reduce weight – especially in the short term. But they don’t correct the underlying causes of weight gain, such as hormonal imbalances, metabolic disorders, or emotional eating habits.

If you’ve tried diets, medications or exercise only to regain weight later, it may be time to consider a comprehensive medical solution.

A Medically Proven Approach: Bariatric Surgery for Sustainable Results

Bariatric surgery is not a cosmetic procedure – it’s a scientifically validated treatment for obesity and related health issues. In countries like the UK, Germany, and the USA, it is considered the gold standard for long-term weight loss.

At AIWA Clinic, we’ve been performing bariatric surgery since 2005, with a focus on safety, innovation, and long-term outcomes.

What we offer:

• Modern, minimally invasive techniques with rapid recovery
• Significantly reduced complication risks, thanks to laparoscopic (keyhole) surgery
• Up to 70–80% excess weight loss – with long-lasting results
• Personalised medical support before and after the procedure

The Bottom Line

Injectable medications like Ozempic and Wegovy can offer real weight loss benefits, especially at the start of your journey. But they’re not a permanent solution – and they come with limitations that are worth considering.

If you’re looking for sustainable weight management, improved health, and support at every stage, bariatric surgery remains one of the most effective options available today.
