Hi, your ulcerative colitis
has nothing to do with dvt. DVT is due to vascular pathology due to clotting prolem and hence your doctor has put you on anticoagulant
. This medicine needs to be taken for a longer lenth of time but results are good. Foods containing fat and or oils need to be minimized. Cardiac problem , if any, needs to be diagnosed early so that breathing problem can be taken care. Talk to your Physician and ask him any further investigations are required to evaluate cause of dvt.
