GLP weight loss injections

If you are someone who is seeking help to lose weight, you may have researched injectable weight loss treatments, or GLP-1 agonists. These drugs are designed to boost weight loss alongside a healthy diet and regular exercise program. Everyone has different needs when it comes to losing weight and the important thing is finding the right treatment for you.

What is true for everyone however, is that losing excess weight can reduce health risks such as diabetes, risk of stroke, risk of cardiovascular disease and risk of some cancers, so it’s an important and wise decision to make, for a longer, healthier and more active life.

How do glucagon-like peptide 1 (GLP-1 agonists) injections work?

When injected either by a special self-administering device, GLP-1 agonists mimic a natural hormone within your body. GLP-1 is responsible for stimulating insulin production and reducing the levels of blood sugar. The drug binds to GLP-1 receptors and releases insulin, thus regulating your blood glucose. This can also affect the hunger and craving centres within your brain, making you feel satiated and less hungry for the wrong types of foods.

Popular weight loss drugs include tircapatide, semaglutide and liraglutide.

Frequently Asked Questions

Am I suitable for GLP-1 weight loss injections?


If you are struggling to lose weight and are already on a healthy diet and exercise regime, weight loss injections may be suitable for you. However, before considering starting on a weight loss program with GLP-1 weight loss injections it’s important to consult with a medical professional, so you can discuss your weight loss issues, have a general health check and understand what is involved in the process.

You may be eligible for prescription of weight loss injections if:

• You have a BMI over 30
• You have a BMI over 27 and have weight-related health concerns, such as diabetes, high blood pressure, raised cholesterol or heart disease.

GLP-1 weight loss injections are not suitable if:

• You are pregnant or breastfeeding
• You have type 1 diabetes
• You have a personal or family history of thyroid cancers or specific genetic conditions
• You have severe liver or kidney problems
• You have an allergy to any of the ingredients in the medication

You will need to speak with your medical practitioner before starting any weight loss treatment if you have a history of:

• Serious digestive issues
• Kidney problems
• Pancreatitis
• Diabetic retinopathy

How do I take GLP-1 weight loss medication?

You can self-inject weight loss medications just under the skin using a special injection pen. Injections can be placed in your upper arm, abdomen or in your thigh. Semaglutide is taken once a week, whereas liraglutide is taken daily.

Do I need to change my diet when I am taking GLP-1 weight loss medication?


Weight loss injections are designed to be taken as part of a healthy weight loss plan and not as a stand-alone treatment. To ensure success in losing weight it is vital to make the necessary lifestyle changes required, such as eating a calorie and portion controlled diet and maintaining a regular exercise regime.

What are the benefits of GLP-1 weight loss injection treatments?


GLP-1 weight loss injections offer a significant improvement in the chances of you losing weight compared to some other commercial weight loss plans. However, consistency is key with weight loss injectables and sticking to the correct dosage as well as a healthy lifestyle will help you achieve your goals.

GLP-1 weight loss injections mimic the hormones that signal to your brain that you are full. Therefore, they can help curb hunger and slow the rate at which your stomach empties after having a meal. This can help reduce cravings and help you to feel more satisfied.

GLP-1 weight loss injections can help to lower your blood pressure, lower cholesterol levels and improve cardiovascular health, thus reducing the risk of heart and kidney diseases.

You may also find that weight loss injections are more convenient to take than weight loss pills, as they are administered either once daily or once weekly. This can be easier than having to take pills, which need to be consumed prior to each meal.

How safe are GLP-1 weight loss injectables?


Semaglutide, tirzpatide and liraglutide are all approved for use in the UK. However, it’s vital that you seek medical advice and management and that your treatment plan is prescribed and monitored by a licenced clinician. Your medical practitioner can also monitor and keep an eye on any side effects as well as your overall health.

Are there any side effects?


Like all medications, weight loss injections can cause some side effects, as your body adjusts. These include the following symptoms:

  • Nausea, vomiting, diarrhoea and constipation: gastrointestinal symptoms are common (approx 1 in 10 patients), usually in the first 10 days following initial dose or dose increase, and are often nothing to be concerned about.
  • Stomach problems such as heartburn or abdominal pain.
  • Headaches
  • Irritation or redness around the injection sites.

Your practitioner will explain side effects and what to look out for during consultation. We also have a dedicated support team to address any concerns if symptoms are persistent or serious.

The best way to avoid GLP-1 side effects is to start with a low dose of the medication and only increase when your body is fully adjusted.

Drinking plenty of water and staying hydrated will help to ease any gastrointestinal side effects. Electrolyte drinks or supplements are good when suffering with diarrhoea. Ginger or mint teas are great for soothing nausea.

Eat food slowly, in smaller, more frequent meals, and stop when satisfied. A balanced diet full of fibrous fruit and veg can help if you are constipated. If alcohol, fatty foods or spicy foods irritate your stomach, this could be exasperated whilst you’re taking medication.
