As many of you are probably well aware, proper dosages of medications usually need to be scaled to one's body weight. A child needs to take much less of a medication than a full-grown adult; an elderly adult also often needs to take less than a younger adult due to decreased muscle/body mass. Likewise, a very fat person will need a higher dose than a skinny person, or else the med will be too diluted in that greater body mass to produce the required effect. Contrariwise, when you lose enough weight, you eventually need to get your prescriptions scaled down, or else you'll be taking way too much for your new body mass.
Now at this point I've lost around 97 pounds, which represents almost 1/3 of my original starting weight. I've been on a bunch of long-term prescriptions for some years now, including blood pressure meds (Maxzide and lisinopril), and figured I probably needed to get those scripts readjusted at some point, but somehow never quite got around to it. My excuse, and it's not such a flimsy one, is that it's a royal pain in the ass trying to get in to see my primary care physician--half the time when I call up, I get told she is booked up solid for the next couple of months, they aren't even taking appointments further out, and to call back in a month when they start taking appointments again. And then I'd call back in a month or so, and discover once again she was all booked up and they weren't taking any more appointments ...
Well, apparently all of this came to a head (so to speak!) last night.
We've been having unseasonably hot Santa Ana weather around here, so my home office has been a little sweat box. Still, I'd been soldiering on with my work, and had even snuck down to the exercise room when things cooled off after sunset for some stationary bike time. And I guess I wasn't drinking quite enough water, and then innocently compounded the mess by eating a bowl of low fat but extremely salty popcorn ... So in hindsight it was not so surprising that, around 10pm, I was sitting at my desk typing at the computer, and suddenly start to feel extremely woozy.
I was fading in and out, and had gotten as far as vaguely thinking "Gee, maybe I should go lie down..." when Mama Nature took matters into her own hands. I came to on the floor, next to my desk, with no memory of having fallen--just a head fulla fuzzy, and a lovely gash in the skin between my nose and upper lip. I still have no idea what the hell I caught my lip on--I'm thinking one of the corners of my desk, though there's no tell-tale blood spatters. In fact, thank goddess, the wound didn't bleed all that much at all. Didn't hurt anywhere near as badly as I would have expected either. But still--ow. And it was deep enough to definitely need stitches, and probably a tetanus shot too.
My roommate, bless his heart, was very oblidging about whisking me away to the emergency room of my HMO's hospital (which is fortunately less than 1/2 mile away). The ER folks of course got all concerned about why this lady fainted dead away out of the blue, as that could potentially be due to any number of things, some of them quite dire. But as they start running tests, they determined that my EKG and blood sugar and reflexes and such were totally textbook perfect, but that I was indeed severely dehydrated. And most entertaining of all was my blood pressure reading.
Time was when I'd regularly get systolic readings (the first number of a typical BP reading) up around 134, 140, and even higher. Meds would bring it down to 120-ish over 80-ish, which is considered normal. But last night, the ER folks were getting readings on me as low as 97/67. Yeowch! No wonder I fainted!
In fact, what I had experienced was a classic episode of syncope (the medical term for fainting) as is often seen with hypotension due to dehydration, such as can be brought on by the diruetic in Maxcide and by ACE inhibitors such as lisinopril, especially if there's also insufficient fluid intake. In other words, between the apparent excessive dose of BP meds due to decreased body mass, the hot weather, the not drinking enough fluids, and that damn salty popcorn, I guess I produced the perfect storm of syncopes.
So they dripped a couple bags worth of saline into my veins (it's amazing how much I perked up within a few minutes of them starting the IV), sutured up that lovely gash in my lip, and gave me a tetanus shot. They also got me an emergency appointment with another doctor in the same clinic as my primary care physician to adjust my meds--apparently even they couldn't get a toehold in my regular doc's appointment calendar, even for an urgent issue. They also instructed me in the meantime to not drive (yikes!--yep, definitely grateful this didn't happen while I was behind the wheel!).
While I'm waiting for my meds to be redone I'm also supposed to take my blood pressure daily with my home BP unit (which of course I had not done in weeks), and if it's well underl 120/80 again to just skip my hypertension meds for that day. I took it this morning and it was around 107/mumble, so no Maxzide or lisinopril for me today.
So how's that for a fun evening of excitement? (Insert glyph of sarcasm here.)
But seriously, I really am glad I had this incident in the relative safety of my own home as opposed to out in public--especially out in traffic! Obviously, I wish that somebody had warned me about the hazards of letting this meds-readjustment thing go unaddressed for so long--alas, the person overseeing my HMO's weight loss group, while a trained weight loss counselor, is not a physician. But still, I think there should be some sort of warning about this kind of thing somewhere.
Which is another reason why I'm blogging about it so extensively here. On a certain level, losing enough weight to mess with one's meds is the kind of problem you don't mind having--after all, it means you're actually getting somewhere with the weight loss. But when one's goal is healthy weight loss, it's still a problem one wants to avoid. I'm still annoyed at myself about the gash--even though the doc took great care stitching it up, I'll probably wind up with a little scar--but I'm glad that's the worst I got off with.
P.S. I'm now wondering why this problem didn't surface when I was in the hospital for the full hysterectomy this past August, or during any of the followup visits. After all, they took my blood pressure about a bazillion times throughout that. But I make a point of seeing what reading they get when they do my BP, and right now I'm not recalling any excessively low readings. I'm also wondering if the surgically-induced menopause from the removal of my ovaries might also have added to my little hypotension mess in some way. Who knows?!? It's a puzzlement to moi!
