GLP-1 Drug Use Can Increase the Risk of Deep Vein Thrombosis (DVT) and Pulmonary Embolisms (PE)
Introduction
There is some evidence to suggest a direct causal relationship between GLP-1 (glucagon-like peptide-1) drugs and an increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE). GLP-1 receptor agonists are a class of medications commonly used to treat type 2 diabetes and now weight loss. These drugs, including exenatide, liraglutide, dulaglutide, tirzepatide (Mounjaro & Zepbound) and semaglutide (Ozempic, & Wegovy), work by mimicking the action of GLP-1, a hormone that regulates blood sugar levels.
Understanding Deep Vein Thrombosis (DVT) and Pulmonary Embolisms (PE)
Deep vein thrombosis (DVT) and pulmonary embolism (PE) are both manifestations of venous thromboembolism (VTE). DVT occurs when a blood clot forms in a deep vein, usually in the legs. If a portion of the clot breaks off and travels to the lungs, it can result in a pulmonary embolism, a potentially life-threatening condition.
Risk Factors for DVT and PE
Several risk factors contribute to the development of DVT and PE. These include:
Immobility
Prolonged periods of immobility, such as during long flights or bed rest after surgery, can increase the risk of clot formation.
Surgery and Trauma
Surgeries, especially those involving the lower extremities, and traumatic injuries can elevate the risk of clot formation.
Cancer
Cancer and certain cancer treatments can increase the likelihood of blood clotting.
Genetic Factors
Inherited conditions that affect blood clotting can predispose individuals to VTE.
Obesity
Excess body weight is associated with an increased risk of clot formation.
Hormonal Factors
Hormonal changes, such as those related to pregnancy or the use of hormonal contraceptives, can contribute to clotting.

GLP-1 Drugs and Cardiovascular Safety
Cardiovascular safety has been a focus in the development and evaluation of GLP-1 drugs. The cardiovascular safety of these medications has been examined in large-scale clinical trials, with a primary focus on major adverse cardiovascular events (MACE), including myocardial infarction, stroke, and cardiovascular death.
As of my last knowledge update, the results of major clinical trials, such as the LEADER (Liraglutide Effect and Action in Diabetes: Evaluation of Cardiovascular Outcome Results) trial for liraglutide, have generally demonstrated cardiovascular safety. These trials provided evidence that GLP-1 receptor agonists do not increase the risk of major cardiovascular events and, in some cases, may even confer cardiovascular benefits.
Limited Evidence Regarding DVT and PE
While the cardiovascular safety of GLP-1 drugs has been studied extensively, there is limited and studies regarding their association with an increased risk of DVT and PE.
Observational Studies
Some observational studies have explored potential links between GLP-1 drugs and thrombotic events. However, these studies often have limitations, and their findings are not consistent.
Meta-Analyses
Meta-analyses have attempted to pool data from multiple studies to assess overall trends. However, the results of these analyses have been mixed, and the overall evidence remains inconclusive.
Potential Mechanisms and Considerations
While direct evidence linking GLP-1 drugs to DVT and PE is limited, it is essential to consider potential mechanisms and patient-specific factors:
1. Cardiovascular Effects of GLP-1 Receptors:GLP-1 receptors are found not only in pancreatic cells but also in various tissues, including the cardiovascular system. The activation of these receptors can influence cardiovascular function.
2. Individual Patient Characteristics: The overall risk of DVT and PE is influenced by a combination of factors, including age, gender, comorbidities, and lifestyle. Individual patient characteristics play a crucial role in determining the risk of thrombotic events.
3. Underlying Diabetes and Cardiovascular Risks: Individuals with diabetes are already at an increased risk of cardiovascular complications, including atherosclerosis and venous thromboembolism. The underlying condition and its associated risks contribute significantly to the overall cardiovascular profile of patients.
Patient-Centric Approach and Risk-Benefit Assessment
The decision to prescribe GLP-1 drugs, like any medication, involves a comprehensive risk-benefit assessment. Healthcare providers consider the potential benefits of improved glycemic control, cardiovascular outcomes, and weight management against the potential risks associated with the medication.
For individuals with diabetes and their healthcare providers, open communication is crucial. Patients should inform their healthcare providers about their medical history, including any history of clotting disorders or risk factors for DVT and PE. Providers, in turn, can tailor treatment plans based on individual patient characteristics and the available evidence.
