coumadin

I've read that Coumadin does not cause weight gain but that changing your diet to eating less veggies with vitamin k may cause weight gain if your calorie goal increases.

I don't have any personal experience with being on it myself. - but many patients I work with are on it.

I don't think it has any direct correlation to weight loss or weight gain.
Coumadin (or Warfarin) is not something you would be put on willy nilly though - if you have a cardiac condition or a blood disorder or have had a DVT - then your first priority is avoiding a clot and/or controlling your cardiac rhythm. Much more important than a theoretical and minimal effect on weight.

There is no need to avoid foods high in Vitamin K - mainly leafy green vegetables like broccoli, asparagus, lettuce.
your INR (blood test that measures your clotting time) will be regularly checked and your dose adjusted to your individual requirements, including your individual dietary intake.
It doesn't matter whether you eat lots of leafy greens or not - ideally be boring and don't vary your intake significantly though as this will cause your INR to be less stable - ie eat more or less same amount of them each week - don't go on a leafy green blitz one week and eat none the next.

The other thing to remember is that many medications interfere with effect of Coumadin - obviously any other long term regular medications you are on will also be factored in to your individual dose - no problems there.
But be aware that some OTC medications can also do this particularly Fish Oil supplements and St Johns Wort and any multi vitamins containing Vit K.
You need to let your Dr know if you start or stop taking any OTC medications or supplements.

Some antibiotics interfere with it as well - but if your Doctor puts you on antibiotics, they will usually keep a closer eye on your INR.
If you get put on antibiotics by anybody other than your regular GP, make sure you let them know you are on Coumadin.

I have been on it for over a year, and have to be on anticoagulants for my whole life. It is very sensitive to changes in your diet, activity and other medications, which is why you need to have regular blood tests to check that your blood is clotting at the right rate.

You can eat things with vitamin K in them, but only if you are consistent about it and eat the same amount every day. It's the changes that will make a difference - if you rarely eat leafy veg, for example, and then eat 2 kilos of it one day, that would affect the way the coumadin works. But if you have the same amount every day, your dose will naturally be adjusted to take account of this through your regular INR tests.

I have been extremely fatigued since being on it - my doctor says he doesn't think it can possibly be the coumadin, but I have read a lot of reviews, comments etc from a lot of different people on different forums saying that it has made them very tired. This could cause weight gain if it prevents you from exercising. I've just yesterday switched to one of the new blood thinners, Xarelto, to see if that helps with the fatigue, so if you get similar problems or feel it is not making you feel well, then there are other options.

The most important thing is that you stay safe, and the coumadin will help with that. Good luck with everything!

I was on it for 6 months and it didn't seem to affect my weight loss any. *shrug*

I am a lifer. It does limit the foods I can eat, which can be a pain, but I do eat quite a bit of kale, just not as many veggies as I would like. Then you can not have protein bars or protein powder either, as most have soy in them. You have to watch like flax seed, chia seed. I find anything that is considered extremely healthy and a superfood, has some sort of effect on inr whether up or down. Tumeric is supposed to prevent cancer or something - can't have that.

The coumadin clinic will advise you. It is better than being on those other blood thinners though. If you get a bleed on them - there is no antidote. I don't mean the heparin shots I mean all those new drugs they advertise on tv commercials.
