1. What Are GLP‑1 Receptor Agonists?
GLP‑1 (glucagon‑like peptide‑1) agonists such as semaglutide (Ozempic, Wegovy) and tirzepatide (Mounjaro) are injectable therapies originally developed to treat type 2 diabetes. By enhancing insulin secretion, reducing appetite, and slowing gastric emptying, they deliver powerful metabolic and weight-loss effects. Their use has rapidly expanded: an estimated 1.5 million people in the UK are using these medications.
2. Emerging Safety Concerns: Pancreatitis & Rare Fatalities
The MHRA’s Yellow Card scheme reports up to 574 suspected cases of pancreatitis linked to GLP‑1 drugs, with 10 fatalities—including five with tirzepatide and one with semaglutide.
Most cases are mild, but severe pancreatitis can be life-threatening, making early detection and monitoring essential. Symptoms typically include:
-
Severe abdominal and/or back pain
-
Nausea, vomiting, fever
-
Elevated pancreatic enzymes on blood tests
3. Conflicting Evidence: Clinical Data vs Real‑World Reports
Meta‑analyses of RCTs (e.g., 34,721-patient semaglutide trials) show no increased risk of acute pancreatitis (OR 0.7; 95 % CI 0.5–1.2) ().
Real-world data (e.g., TriNetX, US) also indicates no elevated pancreatitis risk in patients without comorbidities .
This suggests that while GLP‑1s remain safe for many, rare adverse outcomes—possibly due to genetic predisposition or concurrent conditions—may occur.
4. Genetic Factors & Yellow Card Biobank Study
The MHRA and Genomics England launched the Yellow Card Biobank, calling for individuals hospitalised with pancreatitis on GLP‑1s to submit saliva samples. Their aim is to identify genetic markers for susceptibility and develop safer prescribing strategies.
This reflects a move toward personalised medicine, potentially enabling preemptive identification of high-risk patients.
5. Benefits of GLP‑1 Therapy vs. Risks
Benefits:
-
15–20 % weight loss over 52 weeks
-
Improved glycaemic control and cardiovascular benefits
-
Potential renal, cognitive, and anti-inflammatory effects ()
Risks:
-
Common GI side effects (nausea, reflux, constipation)
-
Rare but serious: pancreatitis (≈1 %), gallbladder disease, thyroid issues, retinopathy, kidney injury
Balancing tremendous benefits against small but real risks underscores the need for tailored treatment and monitoring.

7. Patient Checklist Before Starting GLP‑1 Treatment
Ensure:
-
BMI ≥ 30 kg/m² (or ≥ 27 with comorbidity)
-
No history of pancreatitis or gallbladder disease
-
Face-to-face consultation with medical assessment
-
Baseline and ongoing blood testing is arranged
-
Full disclosure of costs, aftercare, and emergency access
-
Provider is GMC/NMC/GPhC registered with UK clinic premises
If any of the above aren’t in place, seek a regulated and accredited provider, like Haus of Ästhetik.
8. Take‑Home Message
