**8. Venous thromboembolism in CD**

Hypercoagulability with elevated homocysteine level and low vitamin-K-dependent anti-coagulant proteins (protein C & S) are relatively common in CD patients. Due to these factors, i.e. increased homocysteine level and decreased protein C &S, along with autoimmunity of CD, there might be increased susceptibility to venous thromboembolism. Although not commonly observed in CD patients [73].
