Tequila makes you poop for the same reason most alcoholic drinks do: alcohol speeds up your digestive tract, pulls water into your intestines, and irritates the gut lining. But tequila often gets singled out because of how it’s consumed. Shots hit your stomach fast, margaritas load you up with sugar and citric acid, and a night of tequila drinking tends to involve higher quantities than a casual beer or glass of wine. The result is a perfect storm for your bowels.
How Alcohol Affects Your Gut
When alcohol reaches your digestive system, it changes how your intestinal muscles contract. Normally, your colon uses two types of movement: one that slows things down so water can be absorbed, and one that pushes waste toward the exit. Alcohol suppresses the slowing contractions while boosting the pushing ones. The net effect is that everything moves through faster than it should.
That speed matters because your large intestine’s main job is to pull water out of waste and compact it into solid stool. When contents rush through too quickly, your body doesn’t have enough time to absorb that water. You end up with loose, watery stools. Alcohol also irritates the lining of your stomach and intestines, which can trigger your gut to flush its contents as a protective response.
What Makes Tequila Worse Than Other Drinks
Tequila itself isn’t fundamentally different from other spirits in how it affects your intestines. The alcohol content is roughly the same as vodka, rum, or whiskey. What sets tequila apart is how people drink it.
Shots deliver a concentrated dose of alcohol to your stomach all at once, rather than the slower intake you get sipping a cocktail or nursing a beer. That sudden hit can irritate your stomach lining more aggressively and trigger faster gut contractions. If you’re doing multiple shots in a short window, the effect compounds.
Margaritas bring their own problems. The citrus juice (lime, lemon, or orange liqueur) is highly acidic and can irritate your stomach, especially when combined with alcohol. If your stomach struggles to rebalance its pH, that can signal your digestive system to flush everything through quickly. On top of that, many margaritas contain large amounts of sugar from sour mix, triple sec, or flavored syrups. Unabsorbed sugar pulls extra water into your intestines through a process called osmotic effect, making diarrhea even more likely. Bottled lime juice and low-quality sour mixes often contain added citric acid, malic acid, and preservatives that compound the irritation.
Lower-quality tequilas can also contain additives, added sugars, and caramel coloring that some people’s digestive systems react to. If you notice the problem is worse with certain brands, that may be why.
The Timeline
Most people notice the urge to go either later that night or the next morning. Your symptoms should clear up within about 24 hours, depending on how much you drank. If you had a particularly heavy night, loose stools may linger a bit longer as your gut lining recovers and your intestinal bacteria rebalance.
The morning-after effect is partly because your digestive system has been processing alcohol overnight while you slept. By the time you wake up, everything that was moving through at high speed has reached your colon, and your body is ready to get rid of it.
Why Some People Are More Affected
Individual sensitivity plays a big role. People with irritable bowel syndrome or other functional gut conditions tend to have stronger reactions to alcohol because their intestines are already prone to irregular contractions and inflammation. If you have a sensitivity to FODMAPs (a group of fermentable sugars found in many foods and drink mixers), the fructose and other sugars in margarita ingredients can trigger significant digestive distress on their own, even before the alcohol kicks in.
Your gut bacteria also factor in. Alcohol disrupts the balance of microbes in your intestines, and some people’s microbiomes recover from that disruption faster than others. If you’ve noticed tequila hits you harder than your friends, your particular mix of gut bacteria may be less resilient to alcohol’s effects.
How to Reduce the Effect
Eating before you drink is the single most effective thing you can do. Food in your stomach slows down alcohol absorption, giving your intestines more time to process everything at a normal pace. Meals with protein, fat, and complex carbohydrates work best because they take longer to digest and keep the alcohol from hitting your gut all at once.
Switching from shots to slower-sipped drinks helps for the same reason: a more gradual delivery of alcohol is easier on your digestive system. If you love margaritas, using fresh lime juice instead of bottled sour mix reduces the amount of added acid and sugar your gut has to deal with. Choosing a higher-quality 100% agave tequila also eliminates the extra additives found in cheaper “mixto” bottles.
Staying hydrated between drinks won’t prevent the gut motility changes, but it does help offset the dehydration that makes everything feel worse the next day. Plain, bland carbohydrate-rich foods like toast or crackers the morning after can help settle your stomach and give your digestive system something easy to work with while it recovers.
