Weight-loss injections such as Ozempic and Mounjaro have become increasingly popular across the UK, with many patients turning to them for effective, medically supported weight loss. While these treatments can deliver significant results, recent high-profile cases have highlighted that they are not without risks.
One of the most widely reported UK examples is Gemma Collins, who has spoken openly about her experience after using weight-loss injections.
Health Complications Raise Concerns
Gemma Collins, well known for her appearances on The Only Way Is Essex and her continued presence in UK media, revealed that she experienced serious health complications while using “slimming jabs”.
She reported developing gallstones and pancreatitis, both of which are recognised medical risks associated with rapid weight loss and, in some cases, GLP-1 based medications.
Following these complications, Collins confirmed that she had to stop treatment.
Understanding the Risks
While many patients tolerate weight-loss injections well, Gemma Collins’ experience highlights the importance of understanding potential side effects and risks.
Known risks can include:
- Nausea and gastrointestinal symptoms
- Gallstones, particularly with rapid weight loss
- Inflammation of the pancreas (pancreatitis) in rare cases
It is important to note that these complications are not common, but they are clinically recognised and require careful monitoring.
Why Experiences Can Differ Between Patients
Weight-loss injections work by altering appetite, satiety and metabolic signalling. However, each patient responds differently depending on factors such as:
- Underlying health conditions
- Rate of weight loss
- Dosage and escalation
- Diet and nutritional intake
In some cases, rapid weight loss itself, rather than the medication alone, can increase the risk of complications such as gallstones.
A Reminder That Treatment Must Be Medically Led
Gemma Collins’ experience reinforces an important principle in obesity care:
Weight-loss injections should always be part of a structured, medically supervised treatment plan.
Without appropriate assessment and follow-up, patients may:
- Lose weight too quickly
- Develop avoidable side effects
- Stop treatment abruptly without a long-term plan
What Happens After Stopping Treatment?
For patients who stop weight-loss injections due to side effects or other concerns, the next steps are critical.
This may include:
- Reassessing treatment options
- Slowing the rate of weight loss
- Exploring alternative medications
- Considering surgical options where appropriate
Obesity is a chronic condition, and treatment often requires adjustment over time rather than a single fixed solution.
