Can Alcohol Cause Diarrhea? Yes, if alcohol is drunk in high quantity within a short time frame. Alcohol speeds up movement in the intestines, which causes the contents to move past too soon, so insufficient water is absorbed.
In addition, alcohol can irritate the lining of the gut and compromise the seal between the cells that line the intestine. Increased sensitivity of this seal will cause the body to release more water into the stool, which contributes to diarrhea.
According to Dr. Kash Gupta, one should focus on the pattern and not take every symptom for granted. There could be different triggers depending on the kind of alcoholic beverage drunk. Fizzy alcohol is likely to cause bloating, whereas sugar added in drinks leads to loose stools.
People with irritable bowel syndrome or a sensitive gut are more prone to react.
Drinking plenty of fluids after alcohol consumption is essential, especially in case of diarrhea. However, repetitive diarrhea should not be considered normal.
If you experience the symptoms repeatedly after drinking alcohol, they persist for more than two or three days, occur together with severe abdominal pain, bloody stools, dizziness or absence of urine, visit a doctor.
