This could be due to alcohol’s effects on the stomach lining. “What alcohol does really well is it breaks down protein, and your whole [gastrointestinal] lining is made of protein,”Akhil Anand, MD, a psychiatrist specializing in addiction at Cleveland Clinic, told Verywell.
Constipation
The reason that alcohol can causeconstipationis that it can cause dehydration, De Latour explained. “We see that in people who might be really dehydrated as a result of drinking too much because [alcohol] is also a diuretic, so people pee a lot when drinking alcohol,” she said.
Alcohol can also cause you to poop more or less frequently, and it can change theconsistency of your stool. “Alcohol can shake up the frequency of your bowel movements, making you urgently need to poop or disrupting your regular bowel consistency and patterns,” Sethi said.

What to Do If You’re Constipated During Dry January
If you start feeling constipated during Dry January, you may need to examine any dietary changes you’ve recently made. Abstaining from alcohol shouldn’t cause constipation, De Latour explained.
“If you stop drinking, you shouldn’t see a worsening of [constipation] symptoms, per se, because alcohol shouldn’t be the thing that’s helping you poop,” De Latour said.
If you’re experiencing constipation during Dry January, you should make sure you’re drinking enough water and eating ahigh-fiber diet, she said. Foods high in dietary fiber include fruits, vegetables, and grains.
Ultimately, though, pausing or quitting alcohol will only help your bowels (and the rest of your body), De Latour explained.
It’s important to remember that certain changes to your bathroom routine should prompt an immediate healthcare visit—regardless of whether or not those changes are related to alcohol consumption—De Latour said: “You should seek medical attention for any red flags when it comes to stool.”
These include:
Information on how often you’ve been going to the bathroom and how hard or soft your stool has been is helpful for your healthcare provider.
To assess the consistency of your stool, De Latour recommended consulting theBristol Stool Chart, a tool healthcare providers use to determine whether their patients are pooping normally. “The gold standard is for your stool to be very soft, for it to be a three to four on the Bristol Stool Chart,” she explained.
