Overall Venous Thromboembolism (VTE) risk is not significantly increased by GLP-1RA use, as the increase in DVT is offset by no change in Pulmonary Embolism (PE) risk.

Taking GLP-1 medications does not significantly increase your overall risk of blood clots (VTE) when looking at the big picture. While there is a small, non-significant upward trend, it is not statistically proven to be dangerous for the general population. The specific risk of DVT is only significant with very long-term use.
