I was diagnosed with Factor V Leiden after suffering from bilateral PEs in February 2004. I am on Warfarin for the rest of my life (I turn 45 in November). Since starting the Warfarin I have gained about 70 pounds. Nothing I do seem to work. I have tried eating better. I would love to exercise but my knees are shot. Probably from lugging around all this extra weight. Has anybody else had this problem? From what I have read online, doctor will say the drug doesn't cause weight gain but come on. Can anything be done short of stopping the medication? I am too afraid to do that. It sucks that there is not an alternative rx that would work. I suffer from depression too (have for almost 15 years). As my weight has climbed, my meds for depression don't work as well. I am at the end of my rope & slowing losing my grip.
