On Saturday, I increased my dose of Imodium to 1 and a half caplets per day, (a half with each meal). Prior to that, I had not been taking any with breakfast. This is a low dose, but the label says to never take it more than three times in 24 hours, without consulting with a doctor, so the frequency may be more important than the dose, for all I know.
Anyway, yesterday, starting about an hour or so after breakfast, I noticed that I was dizzy, and the effect seemed worse, whenever I stood up, (as if I had postural hypotension), but when I checked my BP, it was elevated a little, rather than low. This morning the dizziness seems to be just about gone.
Dizziness is listed on the label, as a possible side effect of Imodium. I wonder, though, if what I experienced was dehydration. An ileostomy greatly raises one's risk of dehydration. Also, the label on Imodium points out that one should drink additional water, while using Imodium, (which seems counterintuitive, since Imodium allows the small intestine to absorb more water from the fecal stream, but I wasn't aware of that, and maybe it's good advice that I shouldn't have overlooked). Maybe Imodium makes the kidneys more active, because I notice that when I'm taking it, my bladder is always yelling "uncle" every few hours. Without it, I can easily last all night, but when I'm taking Imodium, that time gets cut to about 3 hours, tops.
Maybe, because of the cold weather all weekend, I reduced my water intake, and didn't even notice. Anyway, my question is, has anyone else noticed a greater risk of dehydration symptoms while using Imodium? And, has anyone else noticed that their kidneys seem to be much more active while you are using Imodium, (or is it just me, and there's something wrong with my renal system)? Finally, does this mean that I should be drinking Gatorade, or something similar, to replenish my electrolytes, rather than just plain water?
To complicate the issue, though, here's another possibility: According to expert advice, (found on the web, but not mentioned by any of my doctors), immediately following a colectomy, (complete removal of the colon), electrolytes, (especially sodium), are eliminated at an accelerated rate. Increased electrolyte intake, (primarily salt), is recommended, to counteract that trend. Supposedly, after enough time passes, that accelerated loss will be reduced, as the small intestine begins to adjust, and it "learns" to take over some of the functions that were previously handled by the colon, (mostly, increased fluid absorption). As part of the adjustment, it will "relearn" how to absorb more sodium, and other electrolytes, so that they are not lost in the fecal stream.
Here's why I mentioned that last paragraph: Following my surgery, I developed a habit of eating Lay's Kettle Cooked potato chips, as part of an evening snack, (in place of supper, I would usually nuke some leftover grilled jalapeño pork sausage, and eat it with those chips). Those chips are very salty, which I figured would fit right in with the need for additional sodium, while my small intestine was "going to training school". Well, I noticed that my blood pressure was trending slightly higher, after a while, (not a lot, but enough to approach the "High BP" range). I determined that my BP is fairly sensitive to salt intake, so I stopped eating those chips, a few days before this dizzy event showed up. Hmmmmm.
So maybe I just need to go back to eating those chips for a while, but eat less of them. That's probably not any more unhealthy than drinking Gatorade. Or am I wrong?
It's never easy, is it? Every action has a consequence, and we always seem to be in the position of having to choose the lesser of two evils.
Any thoughts on what you would do, if you were in my shoes, would be appreciated.
Thanks,
Tex
