Fat Loss Injections – Do They Work and Why Safety Testing Matters
Thinking about fat loss injections like Mounjaro? Marylebone Diagnostic Centre, 73 Baker Street, provides essential blood testing, safety monitoring, and support for weight management.
Weight loss can be one of the toughest health journeys. While diet and exercise remain the foundations, some patients are turning to fat loss injections, particularly medications like Mounjaro.
At Marylebone Diagnostic Centre (MDC), 73 Baker Street, London, we do not prescribe these medications directly, but we support clients who are considering or using weight loss treatments. Our role is to ensure you stay safe through comprehensive blood tests, safety monitoring, and wider health services.
What are fat loss injections?
The most common type used for weight management today is:
- GLP-1 receptor agonists such as Mounjaro (tirzepatide) and Ozempic (semaglutide) – originally designed for type 2 diabetes, now widely prescribed for weight loss.
Other options exist, such as vitamin or lipotropic injections, but evidence for their effectiveness is far weaker.
Do they really work?
Clinical studies show GLP-1 medicines like Mounjaro can help patients lose 10–20% of body weight when combined with healthy eating and exercise.
However:
- Results vary from person to person.
- Lifestyle changes remain essential for long-term success.
- Treatment must be monitored for safety.
Why safety testing matters
Fat loss injections can place pressure on the liver, kidneys, and pancreas. Monitoring these systems is essential to reduce risks.
At MDC, we recommend testing before and during treatment, including:
- Liver function tests (LFTs) – check for enzyme changes or damage.
- Kidney function tests (U&E, creatinine, eGFR) – assess filtration.
- HbA1c & glucose – monitor blood sugar.
- Thyroid function tests (TSH, T3, T4) – evaluate hormone balance.
- Full Body MOT – a complete health overview.
