Glucagon-like peptide-1 receptor agonists (GLP-1RAs) have transformed the management of type 2 diabetes (T2D) and obesity. These agents provide robust cardiovascular and renal benefits, making them a cornerstone of modern metabolic therapy. However, clinicians must maintain a high level of vigilance regarding GLP-1 receptor agonists safety to ensure optimal patient outcomes. While most patients tolerate these medications well, a specific pattern of adverse events requires proactive monitoring and evidence-based mitigation strategies.
Early clinical concerns regarding acute pancreatitis and pancreatic cancer have largely subsided. Long-term cardiovascular outcomes trials (CVOTs) have effectively dispelled these risks. Nevertheless, the relationship between these medications and thyroid cancer remains a topic of active investigation. Recent data from 2025 suggest an increased rate of thyroid cancer diagnoses during the first year of treatment. Consequently, experts suggest this may reflect detection bias from increased screening rather than a direct causal link. Clinicians should still exercise caution in patients with a history of medullary thyroid carcinoma.
Rapid reductions in blood glucose levels can sometimes trigger sight-threatening eye complications. This phenomenon typically occurs in patients with pre-existing diabetic retinopathy who experience swift glycemic improvement. Therefore, ophthalmologists recommend baseline retinal screening before initiating GLP-1RA therapy. Furthermore, regular monitoring during the first 12 to 18 months of treatment helps detect early worsening of retinopathy. Emerging data also highlight rare signals of non-arteritic anterior ischemic optic neuropathy (NAION), particularly with semaglutide use.
The slowing of gastric emptying is a primary mechanism for both weight loss and the most common side effects of GLP-1RAs. This physiological change increases the risk of retained gastric contents, which poses a significant threat of pulmonary aspiration during general anesthesia or upper gastrointestinal endoscopy. New multi-society clinical guidance released in 2024 emphasizes individualized assessment. Specifically, patients with active gastrointestinal symptoms like nausea or vomiting should follow a liquid-only diet for 24 hours before elective surgery. Moreover, anesthesiologists should consider point-of-care ultrasound to evaluate gastric volume in high-risk individuals.
Gastrointestinal distress remains the leading cause of treatment discontinuation. Clinicians can mitigate these effects by utilizing slow dose titration and educating patients on symptom management. Although these risks are elevated in those with long-standing T2D, standardized quantitative assessment of symptoms in clinical practice will facilitate a better definition of the benefit-risk relationship for each patient.
Recent large-scale analyses show a spike in diagnoses during the first year of use. Most experts believe this is due to hypervigilance and increased use of thyroid ultrasound rather than the drug causing new tumors.
Current 2024 guidelines suggest that most patients can continue their medication. However, those at high risk for aspiration or those experiencing gastrointestinal side effects should switch to a liquid diet 24 hours before the procedure.
Rapidly lowering high blood sugar can temporarily worsen diabetic retinopathy. A baseline exam ensures that any existing retinal disease is managed before the metabolic shifts occur.

An 11-year Swedish registry study of 618 uterine sarcoma patients found that minimally invasive surgery yielded survival comparable to open surgery in early stages. However, adjuvant chemotherapy conferred no survival benefit in localized or advanced disease, highlighting stage and histology as key outcomes.
