Good morning (he says with most of the coffee now gone)
My wife frequently eats veggies high in vitamin K (e.g. spinach, kale, dandelion/chicory), sometimes in large quantities, sometimes cooked, other times raw.
sounds perfect
If she is not consistent with what she eats from week-to-week, all other things being equal and in her control, she often does experience fluctuations in her INR significant enough to warrant a temporary dosage change to her warfarin
.
Ok, so you're saying she is flatline without this? Like if she's superduper consistent she's like a line on the graph drawn with a ruler?
She takes warfarin with a target range of 2.5-3.5 and self-tests weekly.
target = 3.0 and glad to know she's testing weekly, ok here is my data for this year so far (not much left now so its a reasonable sample
so just look along the daily dose line and see when I've made corrections, under what circumstances and what amounts of variation in INR I have.
I work on averages, but am guided by my boundaries. I have an amount of experience target shooting (well and doing it out in the field too). What I learn from that (that I bring to my INR management) is that you keep aiming for the same point and just go and pick up the sheet after 5 shots and see where they grouped. You don't adjust your aim or tweak your scope on a few shots.
Next I examine where it is ... my goal with adjustment is to steer myself (in a boat that bobs up and down and the bow faces left or right with every wave) . If you haven't sailed then you'll think its still looking at pictures
the reality is that its far from such; the boat tips side to side with the gusts, the waves move your perspective when they go under at an angle and its easy to make the mistake of attempting to correct every little thing. We tell newbies "keep a steady hand on the tiller"
Look at the apparent 'hot mess' of my above data graph between week 7 and 18 ... but I did not adjust dose too much and indeed just kept a steady hand on the tiller.
Why? well because it was over 2.0 at all times (except where I missed a dose day or so before I tested) and anything like 3.5 is irrelevant to me (even though my RANGE is 2 ~ 3).
I steered down from week 18 dropping my dose to 6.5mg ... and the average line started to follow ... if you read through the graph (its not just a picture) you can see what I did and probably make sense of why. This is the WHY that guides me
using risk analysis based on study data.
Of course when this happens, her warfarin dosage is adjusted accordingly after she reports her INR to her Cardio's office.
all this used to stress me too ... I was so glad to be out of that circus and just looking after myself
When the nurses from the office calls when her INR is above or below her target range, the first thing they ask is, “Have you had any changes to you diet?”
this is the rub isn't it ... the idiots and ********* you have to deal with who think they know something but in reality are just tools at the desk gathering information for the actual manager.
I have never met a more trumped up bunch of dunning krugers than when I speak with receptionists at Clinics. I mean I get it, because its a dead boring repetitive job, and the actual medical professionals behind them just appreciate having consistent staff, so naturally the pick the stupid ones. Like famers breed sheep to be placid and docile.
This adds to my wife's anxiety even though we all know it just requires a dosage change.
so perhaps take that out of her equation and don't tell her. Just give her the pills. Manage that for her?
If you wish, reach out and lets see if we can't make a spreadsheet for you, work together and sort this mess out?
