Wegovy vs Mounjaro: Which Weight Loss Injection Is Right for You?

If you're exploring weight loss injections in the UK, you've likely come across Wegovy and Mounjaro. But which one is better for you?

Let’s compare how they work, what results you can expect, and who they’re best suited for.

GLP-1 vs Dual-Agonist Injections

• Wegovy contains semaglutide, a GLP-1 agonist that slows digestion and reduces hunger.
• Mounjaro contains tirzepatide, which targets both GLP-1 and GIP receptors for an even stronger appetite-suppressing effect.

How Much Weight Will You Lose?

Clinical studies show:

• Wegovy users lose up to 15% of body weight on average.
• Mounjaro users may lose up to 20% of body weight.

Of course, results vary based on adherence, dose, and lifestyle habits.

What About Side Effects?

Both Wegovy and Mounjaro are generally well tolerated, but some users do experience mild side effects — especially during the first few weeks as your body adjusts.

Here’s what to expect:

• Nausea:
  This is the most commonly reported side effect with both medications. It typically eases after a few doses, especially when starting on the lowest dose.
• Constipation:
  Mild constipation can occur with either injection. Staying hydrated and eating fibre-rich foods can help.
• Fatigue:
  Some people feel tired, particularly early on. This tends to fade as your body adapts.
• Injection Site Irritation:
  Redness or soreness at the injection site is minimal and usually goes away quickly.

Mounjaro may cause slightly more side effects compared to Wegovy due to its dual action on both GLP-1 and GIP receptors, but these effects are still manageable for most users.

Wegovy or Mounjaro: Which One Suits You?

• Choose Wegovy if you want proven results with fewer variables.
