I’ve just had a repeat blood test as the previous one showed low potassium levels. They aren’t seriously low, just under the lowest acceptable level, and I’m still on my medication but it’s likely to be an immunosuppressant I take for an autoimmune condition that’s the culprit.
My question is really about the mechanism. Is it the immunosuppressant that affects absorption of potassium-rich foods? Presumably regardless of how rich the diet is in potassium (mine is actually good for potassium, probably richer than most U.K. diets)? I’m not too bothered but I’m curious about how it occurs and so far googling hasn’t produced the answer.
