Medical Support Matters
An estimated 1.6 million people in the UK used injectable weight-loss medication last year, yet a large number - perhaps as many as half stopped - within the first year. The most common reasons? Side effects, poor monitoring, and a lack of medical support.
At the Fleet Street Clinic, we believe that the right medical partnership makes all the difference. With careful assessment, close monitoring, and personalised guidance, we can help you:
- Avoid the cost and disappointment of failed treatment
- Protect your health and wellbeing
- Achieve the best possible results
We provide a premium, medically supervised service for patients using weight loss injections such as Semaglutide or Tirzepatide. Our approach is personalised and supportive, ensuring your treatment is safe, effective, and tailored to your individual needs.
You will receive:
- One-to-one clinical support
- Clear instruction and demonstration of injection technique
- Ongoing monitoring, including blood tests where appropriate
- Regular reviews to guide dose adjustments safely
- Advice about healthy lifestyle changes
Our goal is safe, sustainable weight loss with consistent medical oversight.
What Results Can You Expect?
When combined with dietary changes and increased physical activity, patients typically lose 10–15% of their starting body weight over the course of treatment. Results vary between individuals and depend on factors such as:
- Adherence to the treatment plan
- Lifestyle changes
- Individual response to medication
Some patients may achieve greater weight loss with continued engagement and support.
How the Medication Works
Your medication mimics naturally occurring hormones in the body that help regulate appetite and metabolism. These effects include:
• Reducing appetite and food cravings
• Helping control blood sugar levels
• Slowing digestion so you feel fuller for longer
• Improving insulin sensitivity
• Supporting healthier fat storage
Together, these effects make it easier to maintain a calorie-controlled diet.
Possible Side Effects
Side effects are most common when starting treatment or increasing the dose and usually improve over time.
Common side effects include:
- Nausea, vomiting, or diarrhoea
- Abdominal discomfort
- Constipation
- Headache (reported more frequently with Semaglutide)
- Fatigue
- People with diabetes may experience low blood sugar (hypoglycaemia), particularly if taking other glucose-lowering medications
With good medical support, it is often possible to mitigate these effects without undoing hard-won progress in losing weight.
