Short spoken segment from a YouTube video by Robert Whitfield MD (May 25, 2025) explaining that an urgent need to urinate shortly after drinking coffee—despite a not-full bladder and producing only a small volume—may indicate exposure to mold mycotoxins (or oxalates) in the coffee; the speaker links this to toxin-induced renal/bladder irritation and dehydration as a protective response.
So understanding that this toxin is there. And here's how you can tell aside from the I drank coffee and I felt jittery and cranky sometimes right away, if you have a mast cell response, sometimes an hour later if it's a mycotoxin response. If you drink a cup of coffee and soon after you have to go pee and your bladder's not full, you very likely got mold toxin in your coffee. Because it is so toxic to the kidney and bladder, the body will dehydrate you. It'll pull water out of the blood to dilute the toxin, and it'll give you an urgent signal to pee. And then you go to pee and there's just a half a cup comes out. That's weird. When I really have to pee, I should be having, you know, two or three cups of urine. So why, why did you get that signal? It's your body protecting you, and it's a clear sign that something was toxic or irritating. And it's going to be either oxalate or it's going to be mycotoxin.
