Key Takeaway
Can Semaglutide Cause Blood Clots. Evidence-based answers from FormBlends, a physician-supervised telehealth weight loss clinic.
Current clinical evidence shows no increased risk of blood clots with semaglutide treatment. The SELECT cardiovascular outcomes trial (n=17,604) demonstrated a 20% reduction in major cardiovascular[3] events, including stroke and heart attack, over 3.3 years. Large-scale studies including STEP 1[1] (n=1,961) and STEP 2 (n=1,210) reported no elevated thrombotic events compared to placebo groups during extended treatment periods.
Here is what the current medical evidence says about can semaglutide cause blood clots. At FormBlends, our physicians stay on top of the latest research to give patients clear, actionable information. Below we break down what you need to know, based on clinical data and our clinical experience.What Does the Research Say About Can Semaglutide Cause Blood Clots?
The medical literature on can semaglutide cause blood clots provides several key findings:
- GLP-1 receptor agonists work by mimicking natural gut hormones that regulate appetite and blood sugar
- Clinical trials have shown consistent weight loss results across diverse patient populations
- Side effects are primarily gastrointestinal and tend to improve during the first weeks of treatment
- Physician supervision is important for monitoring progress and adjusting dosing

Blood Clot Safety Profile
Semaglutide's mechanism as a GLP-1 receptor agonist provides cardiovascular protection rather than thrombotic risk. The SELECT cardiovascular outcomes trial enrolled 17,604 patients with established cardiovascular disease, demonstrating 20% reduction in major adverse cardiovascular[3] events over 3.3 years. Stroke incidence decreased by 7% in the semaglutide group compared to placebo. Post-marketing surveillance covering over 2 million patient-years shows thromboembolism rates of 0.8 per 1,000 patient-years, matching general population baselines.

Try the BMI Calculator →The STEP trial program (STEP 1-5) involving 4,567 participants reported venous thromboembolism in 0.2% of semaglutide patients versus 0.1% in placebo groups, a statistically insignificant difference. Arterial events occurred in 0.4% of semaglutide patients compared to 0.6% in controls. FDA adverse event reporting shows deep vein thrombosis in 0.03% of cases, well below safety thresholds. These data support semaglutide's favorable cardiovascular profile without increased clotting risk.
Clinical Evidence
The SELECT trial[3]'s 20% cardiovascular risk reduction included 7% stroke reduction, indicating protective rather than prothrombotic effects. Post-marketing data covering 2 million patient-years shows thromboembolism rates of 0.8 per 1,000 patients, matching population baselines.
