Are weight loss injections safe?

Weight loss injections are medications designed to help people lose weight. They work by mimicking hormones in your body that regulate hunger and blood sugar levels, making you feel fuller for longer and reducing cravings. Common injections include:

• Wegovy (semaglutide)
• Saxenda (liraglutide)
• Ozempic (semaglutide, may be used off-label for weight loss)
• Mounjaro (tirzepatide, a newer option targeting two key hormones for weight loss)

These are usually prescribed for people with a BMI of 30 or higher or those with a BMI of 27+ with weight-related health conditions like diabetes or high blood pressure.

Clinical studies show that weight loss injections can help people lose 10-26% of their body weight over several months. Benefits include:

• Lower risk of type 2 diabetes
• Improved heart health
• Boosted confidence as weight loss progresses
• Better overall quality of life

Like any medication, weight loss injections come with risks. Common side effects include:

• Nausea
• Diarrhoea
• Constipation
• Vomiting
• Headache
• Upset stomach
• Feeling weak or tired
• Injection site reactions

Serious but rare side effects include:

• Thyroid tumors, including cancer
• Pancreatitis
• Gallbladder problems
• Kidney injury
• Serious allergic reactions

Always consult your healthcare provider before starting any treatment to understand the risks and benefits based on your personal health.

Weight loss injections don’t just change your body – they can affect your mind too. Many people feel more confident and motivated as they see results, but some may experience:

• Anxiety about side effects or dependency
• Pressure to maintain weight loss
• Stigma from others who may not understand the treatment

It’s important to approach weight loss as a journey, not a quick fix, and seek support if you feel overwhelmed.

Weight loss injections aren’t suitable for everyone. They shouldn’t be used if you:

• Are pregnant or breastfeeding
• Have a history of thyroid cancer, gastroparesis or pancreatitis
• Have severe kidney or liver disease

Your healthcare provider will assess your medical history and current health to determine if these injections are right for you. Medicspot always requires access to your NHS medical record in order to make a safe and informed prescribing decision.

To get the most out of weight loss injections:

• Follow your clinician’s instructions
• Pair injections with a balanced diet, regular exercise, and good sleep.
• Schedule follow-ups with your healthcare provider to monitor progress and side effects.

• What if you experience side effects? Contact your healthcare provider to discuss whether adjustments or stopping the medication is necessary. They may ask you to reduce the dose for a few weeks.
• What if the injections stop working? Weight loss may plateau. Focus on maintaining healthy habits and consult your clinician for next steps. You may benefit from referral to a dietitian. 
• What if you want to stop taking the injections? Discuss with your healthcare provider how to safely stop, and avoid regaining all the weight you lost.

According to the NHS and NICE guidelines, weight loss injections like Mounjaro, Wegovy, and Saxenda are considered safe and effective for people who meet the criteria. They’ve undergone rigorous clinical trials to ensure their safety and effectiveness.

One common concern is regaining weight after stopping injections. Studies show that most people may regain some weight, but this can be managed by continuing healthy habits like eating well, staying active, and focusing on long-term goals.

🚨 Seek urgent medical help if you experience:

• Severe abdominal or back pain 
• Difficulty breathing or severe swelling (possible allergic reaction)
• Persistent vomiting or dehydration
• Any lumps in your neck, problems with swallowing or breathing or a hoarse voice.

Are weight loss injections safe in the long term?

Weight loss injections like Mounjaro, Wegovy, and Saxenda have undergone rigorous clinical trials to prove their safety and effectiveness. Long-term studies show that they can significantly improve metabolic health and reduce obesity-related risks. However, long-term use may carry a very rare risk of thyroid tumors or gallbladder issues, which your clinician will monitor. It’s crucial to have regular check-ups to ensure safety over time.

Can I take weight loss injections without a prescription?

No, these medications require a prescription. Weight loss injections like Mounjaro and Wegovy are not over-the-counter products and must be prescribed by a licensed healthcare provider. This ensures that the treatment is appropriate for you and minimises risks.

Can I use weight loss injections if I have diabetes?

Yes, some weight loss injections like Ozempic and Mounjaro are specifically designed to help manage type 2 diabetes while promoting weight loss. These medications improve blood sugar control and reduce the risk of cardiovascular disease. Your clinician will help you determine which option is best based on your specific needs.

Can I use weight loss injections alongside other weight loss medications?

It’s not recommended to use multiple weight loss medications simultaneously due to the increased risk of side effects.

Do weight loss injections suppress my appetite completely?

No, they won’t eliminate your appetite entirely, but they help you feel fuller for longer and reduce cravings. This makes it easier to control portion sizes and make healthier food choices without feeling deprived.

Can I use weight loss injections while pregnant or breastfeeding?

No, weight loss injections are not recommended during pregnancy or breastfeeding. If you’re planning to become pregnant, inform your healthcare provider before starting these treatments.

How are weight loss injections administered?

Weight loss injections are self-administered using a pen-like device. You inject the medication subcutaneously (just under the skin), usually in the abdomen, thigh, or upper arm. Your healthcare provider will show you how to do this safely.

Weight loss injections can be a safe and effective tool when used under medical supervision. However, they’re not for everyone. Talk to your healthcare provider to determine the best approach for your weight loss journey.
