Fermanagh Weight Loss Clinic
If you have been considering medical weight loss in Northern Ireland and are trying to decide between Mounjaro and Wegovy, you are not alone. These are two of the most talked-about prescription weight loss treatments available today, and both have strong clinical evidence behind them. At Fermanagh Clinics, we help patients across Fermanagh, Tyrone, and the wider Northern Ireland area understand their options and choose the treatment that is right for them. Book an appointment or contact us to speak with our team today.
Mounjaro (tirzepatide) targets two hormonal pathways (GIP and GLP-1), making it a dual-action treatment with strong clinical results for weight loss. Wegovy (semaglutide) targets one pathway (GLP-1) and is a well-established, widely used treatment with excellent trial data. Both are once-weekly injections. The best choice depends on your health history, weight loss goals, and individual circumstances. Our clinical team at Fermanagh Clinics will help you decide.
What Are Mounjaro And Wegovy?
Both Mounjaro and Wegovy belong to a class of medicines originally developed to help manage blood sugar in people with type 2 diabetes. Researchers found that both caused significant weight loss in clinical trials, which led to their development and approval as dedicated weight loss treatments.
Here is a brief overview of each:
- Mounjaro contains tirzepatide and works on both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 (glucagon-like peptide-1) receptors. This dual mechanism is what sets it apart.
- Wegovy contains semaglutide and targets GLP-1 receptors only. It has been available longer and has a well-established track record in weight management.
Both are administered as a once-weekly subcutaneous injection using a pre-filled pen. Both are prescription-only and require clinical assessment before use.
How Do They Work?
Understanding how these treatments work can help you make an informed decision.
Mounjaro activates both GIP and GLP-1 receptors in the body. This dual action:
- Reduces appetite and food intake
- Slows gastric emptying, helping you feel fuller for longer
- Improves insulin sensitivity and blood sugar regulation
- May enhance the body’s ability to burn fat
Wegovy activates GLP-1 receptors specifically. This:
- Suppresses appetite by acting on hunger signals in the brain
- Slows gastric emptying to promote feelings of fullness
- Supports blood sugar control
- Reduces overall calorie intake over time

Clinical Evidence: What Do The Trials Show?
Both treatments have been studied extensively in large-scale clinical trials, and both produced impressive results. Here is a summary of what the evidence suggests:
Mounjaro (SURMOUNT trials):
- Participants lost an average of around 15 to 20% of body weight at the highest doses
- Results were consistently stronger than those seen with GLP-1-only treatments in comparative studies
- The dual mechanism appears to offer additional benefits for metabolic health
Wegovy (STEP trials):
- Participants lost an average of approximately 15% of body weight at the 2.4mg dose
- Significant improvements in cardiovascular risk markers were recorded
- A dedicated cardiovascular outcomes trial (SELECT) showed a reduction in serious cardiac events
Both treatments outperform older weight loss medications by a considerable margin, and both are significantly more effective than lifestyle changes alone for most people when used as part of a clinically supervised programme.
Who Might Be Better Suited To Each Treatment?
There is no single answer that applies to everyone. During your consultation at Fermanagh Clinics, we take a thorough look at your health history and goals before making any recommendation. That said, here are some general considerations:
Mounjaro may be particularly suitable if you:
- Have a higher starting weight and are looking for maximum results
- Have type 2 diabetes or are at risk of developing it
- Have not responded well to GLP-1 treatments in the past
- Want the treatment with the strongest current evidence for total weight loss
Wegovy may be particularly suitable if you:
- Have cardiovascular risk factors, as Wegovy has specific evidence in this area
- Prefer a treatment with a longer established track record
- Have previously used semaglutide and responded well to it
- Are at an earlier stage of a weight management journey
Combining Lifestyle Changes With Weight Loss Treatment
Prescription weight loss treatments such as Mounjaro and Wegovy can produce significant results on their own, but the evidence consistently shows that combining medication with positive lifestyle changes leads to better outcomes and makes those results far more likely to last. At Fermanagh Clinics, we always encourage patients to view their treatment as one part of a broader commitment to their health.
Here are some of the most effective lifestyle changes to build alongside your treatment:
Nutrition
- Focus on whole, minimally processed foods such as vegetables, lean proteins, wholegrains, and healthy fats
- Eat slowly and pay attention to hunger and fullness cues, both treatments reduce appetite, so tuning into these signals becomes easier over time
- Keep protein intake consistent at each meal to help preserve muscle mass as you lose weight
- Limit high-fat and high-sugar foods, particularly in the early weeks of treatment when your digestive system is adjusting
- Stay well hydrated throughout the day. Aim for at least 6 to 8 glasses of water daily
Physical Activity
- You do not need to commit to an intense exercise programme from the start. Even 20 to 30 minutes of walking each day makes a meaningful difference
- Build activity gradually and choose something you genuinely enjoy, whether that is swimming, cycling, or a group fitness class
- Include some resistance or strength-based exercise where possible. This helps protect and build muscle while you are losing fat
- Try to reduce prolonged sitting by taking short movement breaks throughout the day
Sleep And Stress
- Poor sleep is closely linked to increased hunger hormones and weight gain. Aim for 7 to 9 hours of quality sleep each night
- Chronic stress can trigger emotional eating and disrupt the hormones that regulate appetite. Finding ways to manage stress, whether through exercise, mindfulness, or social connection, supports your weight loss journey
Building Sustainable Habits
One of the most important things to remember is that lasting weight management is not about short-term restriction. The goal is to build habits that feel manageable and sustainable in the long run. Treatment with Mounjaro or Wegovy can make this process significantly easier by reducing hunger and cravings, giving you the space to focus on building those habits without feeling constantly overwhelmed by appetite.
The table below outlines how lifestyle factors can complement your treatment:
| Lifestyle Factor | Why It Matters | Simple Starting Point |
|---|---|---|
| Balanced nutrition | Supports fat loss while preserving energy and muscle | Add a portion of protein to every meal |
| Regular movement | Burns calories, improves mood, and supports long-term weight maintenance | A 20-minute walk each day |
| Strength training | Helps maintain muscle mass during weight loss | Two bodyweight sessions per week |
| Quality sleep | Regulates hunger hormones and supports recovery | Set a consistent bedtime and wind-down routine |
| Stress management | Reduces emotional eating and supports hormonal balance | 10 minutes of fresh air or mindfulness daily |
| Hydration | Supports digestion and helps manage side effects | Keep a water bottle with you throughout the day |
Our team at Fermanagh Clinics is here to support you not just with your prescription, but with the broader picture of your health. If you would like guidance on nutrition, activity, or any aspect of your weight loss journey, please do not hesitate to get in touch.
Frequently Asked Questions
Yes, switching is possible and is something we can discuss during a follow-up consultation. If you are not achieving the results you hoped for on your current treatment, or if side effects are an ongoing issue, a switch may be appropriate. Our team will review your progress and guide you on the best next step.
Both Mounjaro and Wegovy are generally indicated for adults with a BMI of 30 or above, or a BMI of 27 or above where a weight-related health condition such as high blood pressure or type 2 diabetes is present. During your consultation, we will assess whether either treatment is clinically appropriate for you.
Weight loss treatments are most effective when used as part of a longer-term plan. Many patients use these treatments for a year or more. Stopping treatment can lead to some weight returning, which is why we always discuss long-term management strategies alongside the prescription itself.
There is no strict diet required, but both treatments work best alongside a balanced, calorie-aware diet. We recommend focusing on whole foods, adequate protein, and avoiding very high-fat meals, particularly during the early weeks when your body is adjusting to the medication. Our team can provide further dietary guidance during your consultations.
We are based at 24 Church Street, Irvinestown, Fermanagh, BT94 1EH, and we welcome patients from across Northern Ireland. No GP referral is needed. You can book directly with us online or by phone, and we will carry out a full clinical assessment as part of your first appointment.
Some patients notice changes in appetite and weight within the first few weeks on either treatment. Clinical trials suggest Mounjaro tends to produce slightly faster and greater weight loss overall, but individual responses vary considerably. Consistency with treatment, diet, and activity levels is the most important factor for most patients.
