Shall we get started?

why does alcohol give you diarrhea

From nights out with friends to celebrating special occasions, alcohol is a common feature in our social lives. However, for some individuals, the aftermath of consuming alcoholic beverages can lead to an unwelcome surprise: diarrhea. This unpleasant digestive issue can ruin an otherwise enjoyable evening, leaving many people puzzled and seeking answers. In my own experience, I have encountered moments where alcohol triggered unexpected bouts of diarrhea, and it made me curious to understand the reasons behind it. So, let’s explore the possible causes together, helping you gain a deeper understanding of why alcohol can give you diarrhea.

What are the Causes of Diarrhea After Drinking Alcohol?

There are several potential causes for experiencing diarrhea after consuming alcoholic beverages. Let’s take a closer look at two of the most common reasons:

Alcohol-Induced Inflammation of the Gastrointestinal Tract

One possible cause of alcohol-related diarrhea is the inflammation it can trigger in the gastrointestinal (GI) tract. When we drink alcohol, especially in excessive amounts, it can irritate and inflame the delicate lining of our intestines. This inflammation can lead to a disruption in normal bowel movements, resulting in diarrhea. The exact mechanisms responsible for alcohol-induced GI inflammation are complex and still being studied, but it is believed that alcohol can increase the production of certain chemicals and stimulate the immune system in the gut, leading to digestive distress.

Alcohol Intolerance and Sensitivities

Another reason for experiencing diarrhea after drinking alcohol is alcohol intolerance or sensitivity. Some individuals have difficulty metabolizing alcohol or may have specific sensitivities to certain components found in alcoholic beverages. For example, some people lack the necessary enzymes to break down alcohol efficiently, which can lead to digestive issues, including diarrhea. Additionally, certain ingredients commonly found in alcoholic drinks, such as grains, yeast, or sulfites, can trigger sensitivities or allergies in susceptible individuals.

It’s important to note that the causes of alcohol-induced diarrhea can vary from person to person, and individual responses to alcohol differ. Factors such as genetics, overall health, and pre-existing gastrointestinal conditions may influence an individual’s susceptibility to experiencing diarrhea after alcohol consumption.

What to Eat and Drink

If you frequently experience diarrhea after drinking alcohol, making mindful choices in your diet can help minimize the occurrence of this unpleasant symptom. Here are some recommendations:

Increase Fiber-Rich Foods

Incorporating more fiber-rich foods into your diet can help regulate bowel movements and promote healthy digestion. Opt for whole grains, fruits, vegetables, and legumes. These food groups are excellent sources of dietary fiber that can help alleviate diarrhea caused by alcohol.

Hydrate, Hydrate, Hydrate!

Staying well-hydrated is crucial to prevent dehydration caused by diarrhea. Diarrhea often leads to significant fluid loss, so it’s essential to replenish your body by drinking plenty of water and consuming electrolyte-rich fluids like coconut water or sports drinks.

How Can You Avoid Diarrhea After Drinking Alcohol?

What to Avoid

If you’re prone to alcohol-induced diarrhea, there are certain things you should avoid to minimize the chances of experiencing digestive distress. Here are a few key tips:

Limit Alcohol Consumption

The most obvious step to avoid alcohol-induced diarrhea is to reduce or eliminate your alcohol consumption. This may involve cutting back on the amount of alcohol you drink or even abstaining from it entirely. By doing so, you give your body a chance to heal and minimize stress on your digestive system.

Steer Clear of Trigger Foods and Beverages

Everyone’s digestive system reacts differently to specific foods and drinks. Pay attention to your body’s responses and identify any trigger foods or beverages that seem to worsen your symptoms. Common triggers can include spicy foods, fatty foods, processed foods, and carbonated beverages. By avoiding these triggers, you can reduce the likelihood of diarrhea after drinking alcohol.

Avoid Mixing Different Types of Alcohol

Drinking a variety of alcoholic beverages in a short period can increase the risk of diarrhea. Our bodies may struggle to process and metabolize different types of alcohol simultaneously, leading to digestive disturbances. Stick to one type of alcohol or limit your consumption of various drinks to minimize GI distress.

Over-the-Counter Remedies for Alcohol-Induced Diarrhea

If you find yourself dealing with alcohol-induced diarrhea, a few over-the-counter remedies may offer relief. However, it’s essential to consult with a healthcare professional before trying any new medications or treatments. Here are some commonly recommended options:

Antidiarrheal Medications

Over-the-counter antidiarrheal medications, such as loperamide (Imodium), can help alleviate the uncomfortable symptoms of diarrhea. These medications work by slowing down bowel movements and providing temporary relief. However, it’s crucial to use them as directed and not rely on them as a long-term solution.


Probiotics are beneficial bacteria that can help restore a healthy balance in your gut flora. Consider taking probiotic supplements or consuming probiotic-rich foods like yogurt, kefir, or sauerkraut. These can help support your digestive system and potentially reduce diarrhea symptoms.

Avoid Trigger Foods and Beverages

In addition to identifying and avoiding trigger foods and beverages, it’s important to be mindful of your overall diet. Opt for easy-to-digest, bland foods when experiencing diarrhea. Examples include toast, rice, crackers, and boiled potatoes. These foods are gentle on your digestive system and can help ease symptoms.

When Should You See Your Doctor?

Most cases of alcohol-induced diarrhea can be managed with the aforementioned home remedies. However, there are situations where it’s crucial to seek medical advice. Reach out to your doctor if:

  • The diarrhea persists for more than a couple of days
  • You experience severe abdominal pain or cramping
  • You notice blood in your stool
  • You feel persistently nauseous or vomit
  • You have a pre-existing gastrointestinal condition, such as IBS or IBD

Remember, your doctor is the best person to evaluate your specific situation and provide appropriate guidance and treatment.
