I was diagnosed with Factor V Leiden after experiencing bilateral PE's in February 2004. Since then, I have gained A LOT of weight. Not that I needed to but dang. I am at my highest ever & nothing I do will make it go down. I am almost 80 pounds heavier than I was in 2004. Something is not right. I suffer from depression (have for more than 15 years). My medication doesn't seem to have the same effect. My joints are killing me so it's hard to exercise. A side note, shortly after being hospitalized for the PE's for a week, I noticed my hair thinning. Doctor told me it was because of the "shock" to my system due to having the PE's. I will have to be on Warfarin for the rest of my life. I turn 45 in November. Ugh. Has anybody had the same problem with weight gain? Is there anything to do about it? I feel I am at the end of my rope & slowing losing my grip.
