Do blood thinners cause weight gain?

My father started blood thinners after a heart issue, and he's gained quite a bit of weight since then. He's very concerned about it. Can blood thinners cause weight gain?

Well, unless you are eating the blood thinners with a side of butter chicken, they don't directly cause weight gain! But seriously, these medicines don't have calories, so any weight change is probably just water retention or a change in your activity level. Don't stress too much about it.

Hello beta. It is quite common to feel a bit heavier or bloated when starting blood thinners, but it is rarely actual fat gain. Keep a daily log of your weight and show it to your doctor. Make sure you drink enough water and avoid processed foods to keep the bloating down.

I just finished my six-month course of blood thinners after a DVT diagnosis. I also felt like I was putting on weight, but my doctor told me it was mostly bloating and lack of movement because I was resting so much. Once I started walking again, the weight went back to normal.

Please be very careful if you are noticing sudden weight gain while on blood thinners. In my case, sudden weight gain was actually fluid accumulation due to heart strain, which became a big complication. You must see your doctor immediately to rule out any serious fluid retention issues.

Medically, blood thinners don't cause direct fat gain. If you're busy and finding it hard to stay active post-prescription, that lifestyle change is likely the cause. Don't waste time worrying; just ask your doctor for a quick diet adjustment chart during your next routine checkup.

Since blood thinners don't directly cause weight gain, focus on your diet. Sometimes, being on these medicines makes us eat more comfort foods due to stress. Stick to a clean, fiber-rich vegetarian diet with plenty of green vegetables, but check with your doctor first as some greens can interfere with certain thinners.
