So, does eggnog cause diarrhea? For many people, yes—especially if you’re lactose-sensitive, sugar-addled, or spice-happy. But it’s not a guarantee. You can enjoy this creamy, joyous beverage without it turning into a 911 call. The key is knowing your gut and respecting its limits.
If you do end up on the porcelain throne after a night of nog, remember: you’re not alone. Millions of people share this seasonal bond. Just blame it on the nutmeg. And maybe invest in some good toilet paper. Happy holidays, and may your bowels be ever in your favor.
