Weight Loss Support
At onlinemeds, we understand that losing weight is not just about appearance but about improving your overall health, confidence, and quality of life. Many people struggle to achieve sustainable results through diet and exercise alone, and medical support can often make the difference. That is why we offer a safe and convenient online service providing access to clinically proven weight loss injections and tablets.
Our expert team assesses each patient individually to ensure the right medication is prescribed and that weight loss treatment is supported with guidance on diet, exercise, and lifestyle changes for long-term success.
What Are Weight Loss Injections and Tablets?
Weight loss medications can support people who have struggled to lose weight through lifestyle changes alone. They work by altering the way the body regulates appetite, food absorption, and blood sugar levels. The most effective treatments currently available include:
Mounjaro (tirzepatide) – a dual-action injectable that targets both GLP-1 (glucagon-like peptide-1) and GIP (glucose-dependent insulinotropic polypeptide) receptors.
Wegovy (semaglutide) – a GLP-1 receptor agonist that helps regulate appetite and calorie intake.
Orlistat – an oral medication that prevents the body from absorbing some of the fat from the food you eat, available as prescription-strength Xenical (120 mg) or the over-the-counter brand Alli (60 mg).
What are the Benefits?
Mounjaro
Mounjaro works on two key hormone pathways, GLP-1 and GIP, which together help control appetite, slow digestion, and regulate insulin. This dual mechanism helps people feel fuller for longer, reduces cravings, and improves blood sugar control. Many patients find it particularly effective for managing both weight and type 2 diabetes.
Wegovy
Wegovy helps control appetite by mimicking the natural GLP-1 hormone released after eating. It slows stomach emptying and sends signals to the brain to reduce hunger. Patients typically experience a steady and manageable weight loss, alongside improvements in metabolic health.
Orlistat
Unlike injections, Orlistat works in the digestive system. It blocks the absorption of up to one-third of dietary fat, which is then excreted naturally. This helps lower calorie intake without directly affecting appetite. Orlistat is most effective when combined with a reduced-fat diet and regular exercise.
How Much Weight Can They Help You Lose?
Results differ from person to person, depending on lifestyle, diet, activity levels, and how well the body responds to treatment. However, clinical studies have shown that prescription weight loss medications can produce meaningful and lasting results when combined with consistent lifestyle changes.
Mounjaro (tirzepatide):
Research shows that Mounjaro can lead to an average 15% to 22.5% reduction in total body weight over a 72-week period. Many participants also experience improvements in blood sugar control and waist circumference. Its dual-action mechanism, targeting both GLP-1 and GIP receptors, helps reduce appetite, improve insulin sensitivity, and support long-term fat loss.
Wegovy (semaglutide):
Clinical trials, such as the STEP studies, found that Wegovy users typically lose 12% to 15% of their body weight within about 68 to 72 weeks. The medication works by reducing hunger and slowing digestion, leading to a lower calorie intake and a steady, sustainable rate of weight loss.
Orlistat:
For those who prefer an oral option, Orlistat offers moderate but reliable results. When taken alongside a reduced-fat, calorie-controlled diet, patients often achieve 5% to 10% body weight loss within six to twelve months. It works by blocking the absorption of some dietary fat, effectively lowering overall calorie intake.
While individual results vary, the greatest success comes from combining medication with positive lifestyle habits such as regular exercise, balanced nutrition, and professional guidance. These treatments act as supportive tools—helping patients gain control over their weight and maintain healthier habits for the long term.
Who is Eligible for Weight Loss Medication?
Weight loss medication may be suitable if you have:
A Body Mass Index (BMI) of 30 or higher, or
A BMI of 27 or higher with a weight-related condition such as:
- Type 2 diabetes
- High blood pressure (hypertension)
- Heart or blood vessel disease
- Obstructive sleep apnoea (confirmed by a sleep study)
- High cholesterol or abnormal blood fats (dyslipidaemia)
Why Might I Not Be Eligible?
You may not be eligible for weight loss medication if:
- Your BMI is below the minimum threshold, or if excess weight is due to high muscle mass rather than fat.
- You are under 18.
- You are pregnant or breastfeeding.
- You take non-compatible medications or have certain medical conditions, including pancreatitis, severe kidney or liver disease, or a personal or family history of thyroid cancer.
All patients are assessed on an individual basis to ensure safety and suitability before treatment begins.
How to Take Weight Loss Injections and Tablets
Mounjaro and Wegovy are administered once a week via a simple injection under the skin (subcutaneous). The injection site should be rotated each time to reduce irritation. Injections should be stored in a refrigerator and used at the same time each week for consistency.
Orlistat is taken as a capsule up to three times a day with meals containing fat. It should be swallowed with water before, during, or up to an hour after eating.
What are Common Side Effects?
Most side effects are mild and improve with time. They can include:
- Nausea, queasiness, or reduced appetite
- Diarrhoea, constipation, or bloating
- Fatigue or mild dizziness
- Headache
- Indigestion or heartburn
- Redness or tenderness at the injection site (Mounjaro and Wegovy)
- Oily stools or flatulence (Orlistat)
Rare side effects include allergic reactions, severe abdominal pain, or pancreatitis. Always seek medical advice if symptoms persist or worsen.

How Long Can I Be on Weight Loss Medication?
The length of time you can safely remain on weight loss medication depends on several factors, including your initial weight, the specific medicine prescribed, and how well your body responds.
Clinical trials, including those published in the New England Journal of Medicine, show that many people use treatments like Mounjaro and Wegovy for up to 72 weeks (around 16 months) with medical supervision. Some continue beyond this period when their prescriber considers it safe and effective for maintaining progress.
Your prescriber will review your progress regularly to ensure the treatment continues to work for you. They will look at your weight stability, any side effects, and updates to your medical history before deciding whether to adjust or stop your medication.
The ultimate goal is not only to help you lose weight but also to support sustainable habits that allow you to maintain your results long term, even after treatment has finished.
Tips to Help You Lose Weight While on Medication
Weight loss medication is most effective when paired with consistent lifestyle improvements. These changes enhance the medication’s effects and help you maintain results once treatment ends.
Exercise
Physical activity is key to healthy and lasting weight loss. Start with manageable goals, such as daily walks, light stretching, or home workouts. Gradually increase your intensity and try to incorporate a mix of cardio, strength training, and flexibility exercises. Activities such as swimming, yoga, and group fitness classes can also make exercise enjoyable and sustainable. Aim for at least 150 minutes of moderate activity per week.
Diet
A nutritious and balanced diet is essential for supporting your progress. Focus on lean protein, whole grains, fruits, vegetables, and healthy fats. Avoid skipping meals or following extreme diets that can lead to fatigue or nutrient deficiencies. Portion control and mindful eating are simple but powerful habits that encourage steady weight loss. If needed, consider speaking to a nutritionist for tailored advice or use a food-tracking app to monitor intake.
Lifestyle
Good health is about more than just food and exercise. Staying hydrated, sleeping well, and managing stress all influence how your body responds to treatment. Try to drink at least 1.5 to 2 litres of water a day, establish a regular sleep routine, and take time to relax through activities like reading, meditation, or walking outdoors. Avoid smoking or excessive alcohol consumption, as both can slow your progress.
Mindset
Approach your journey with patience and a positive outlook. Weight loss takes time, and small, consistent improvements lead to lasting change. If you view your medication as a tool rather than a quick fix, you’ll be more motivated to make healthier choices. Investing in your physical and mental wellbeing adds long-term value to your treatment and increases your likelihood of keeping the weight off.
