You're not doing your hypochondria any favors by looking all of the various increased risk factors of having uc. We're all born with increased risk factors based on our gender, ethnic heritage, family's genetics (health history of close relatives), where we live, how active we are, and our weight, and diet, and so many other things. I'd try not to worry.
"The cumulative chance of developing DVT over a lifetime ranges from 2 percent to 5 percent for the general population. While certain conditions can provoke DVT (such as cancer, surgery, and being confined to bed), this condition may also occur spontaneously. Approximately 20 to 40 percent of people who develop spontaneous DVT have an inherited or acquired predisposition to thrombosis or thrombophilia"

This risk is higher during disease flares, both for inpatients and outpatients. However, during hospitalisation, multiple prothrombotic risk factors other than active disease act synergistically, multiplying the absolute risk of VTE. "
