Unwinding with a couple of drinks sounds like a great idea, especially after a long, tiresome week. Unfortunately, for some, the aftermath may not be as pleasant as the night before. A common but rarely-discussed occurrence that may follow alcohol consumption is diarrhea. You are not alone if you are constantly forced to sprint to the bathroom upon waking up after a night of heavy drinking.
At Nirvana Recovery, we recognize how various drugs affect the body. For example, alcohol can trigger a stomach upset or diarrhea after interfering with the digestive system. While its effects on the stomach are mostly temporary, prolonged experiences usually indicate a deeper issue, such as an underlying health concern.
In this blog, one of our treatment professionals discusses the relationship between alcohol and diarrhea, the symptoms to watch out for, preventive strategies, and effective remedies. Contact us for professional intervention and support for alcohol-related issues.
Why Does Alcohol Cause Diarrhea?
To fully explain the relationship between alcohol and diarrhea, we will focus on two key gut functions: digestion and intestinal absorption. Read below to discover how alcohol affects digestion and intestinal absorption, and the types of alcohol likely to cause diarrhea.
Effects of Alcohol on Digestion
Alcohol irritates the gut by interfering with its natural rhythm and function. To be more specific, it increases gut motility, making food and liquids move faster through the intestines. The rapid movement makes the intestines absorb water and nutrients faster, leading to looser and more frequent stools.
Alcoholic beverages also disrupt the delicate balance of healthy gut bacteria (gut microbiota) that helps in digestion and nutrient absorption. This disruption can trigger gut irritation, inflammation, and bowel irregularities like diarrhea.
Lastly, consuming large quantities of alcohol can affect the stomach lining, leading to gastritis. Resultant effects include increased nausea, cramping, and bowel issues.
Alcohol's Impact on Intestinal Absorption
Besides digestion, alcohol can impair intestinal absorption in the following ways:
It can limit the small intestine’s ability to absorb water and nutrients.
It can inhibit the production of digestive enzymes while damaging the intestinal lining. As a result, the body may struggle to absorb the much-needed fluids and electrolytes.
Frequent or chronic alcohol consumption can trigger malabsorption syndromes, further leading to chronic gastrointestinal issues. Individuals affected by these symptoms usually struggle to absorb crucial nutrients like folate, Vitamin B12, and Iron.
Types of Alcohol Most Likely to Cause Diarrhea
Alcoholic beverages affect the gut differently due to their composition: some are more likely to cause diarrhea. Below are the most common types:
Beer: Beer has high concentrations of gluten and fermentable carbs, which can easily irritate the gut. It mainly triggers diarrhea among consumers with gluten sensitivities or Irritable Bowel Symptoms (IBS).
Wine: Most wines have sulphites and residual sugars, which can easily upset the digestive system.
Spirit combos: While spirits like vodka and gin have lower carb concentrations, they can easily irritate the gut lining, especially when consumed in combination with fruit juices or sugary sodas.
Before you start drinking, remember that your consumption method, the type of drink, and its composition will determine the aftermath.
Common Symptoms Accompanying Alcohol-Induced Diarrhea
Alcohol-induced diarrhea manifests in several ways. While most symptoms are short-lived, some may recur. Read on to discover common, immediate, and additional symptoms as well as signs of a bigger issue.
Immediate Symptoms
Alcohol can trigger diarrhea within a few hours of drinking or the next morning. Watch out for the following symptoms:
Loose/watery stool
An urgent need to defecate
Cramping in the abdomen
Bloating/excessive gas
The symptoms above signify how the body responds to alcohol-induced intestinal irritation or rapid digestion.
Additional Digestive Symptoms
Besides the symptoms above, you may also witness the following:
Nausea or vomiting
Pain or a burning sensation in the stomach
Mild dehydration
Fatigue (due to excessive fluid loss)
Diarrhea may also cause severe fluid loss, leading to dizziness, a dry mouth, and reduced urine output.
When Symptoms Might Signal a Bigger Issue
If symptoms persist for 2 days (or more) or frequently occur despite changing your drinking habits, you probably have an underlying issue. Common gastrointestinal conditions associated with alcohol include the following:
Alcohol intolerance/allergy.
Irritable Bowel Syndrome (IBS)
Alcohol intolerance/energy.
Inflammatory bowel disease.
Seek professional intervention if your digestive problems recur after consuming alcohol.
Risk Factors That Increase Diarrhea After Drinking Alcohol
Alcohol-induced diarrhea does not discriminate. However, it is more common in people with pre-existing digestive conditions, poor dietary habits, and unhealthy alcohol consumption patterns. The factors below increase the risk of diarrhea after consuming alcohol:
Pre-existing Digestive Conditions
Individuals with the following conditions are more likely to suffer diarrhea after drinking:
Irritable Bowel Syndrome (IBS): People with IBS have a sensitive gut. Symptoms like cramping and loose stool usually worsen after drinking.
Lactose intolerance: Cream-based or dairy-based alcoholic products may trigger gas and diarrhea in lactose-intolerant individuals.
Celiac disease: Beers or liqueurs with gluten can trigger inflammation in individuals with celiac disease or gluten sensitivity.
Besides the above, individuals with Crohn’s disease or Ulcerative Colitis should exercise a level of care to avoid flare-ups or worsening symptoms. Remember, moderate alcohol consumption can still interfere with a sensitive gut.
Dietary Habits and Alcohol Consumption Patterns
Drinking patterns and dietary habits matter. Here is how the following consumption tendencies or patterns can predispose individuals to gastrointestinal issues like diarrhea:
Drinking while hungry: Taking alcohol on an empty stomach accelerates its absorption and may increase irritation.
Binge drinking: Non-stop alcohol consumption can lead to dehydration as it overwhelms the digestive system.
Mixing drinks: Combining different alcohol types in one sitting or pairing drinks with fatty, rich, or spicy foods may cause further stomach upsets.
Fix your dietary habits or avoid erratic alcohol consumption patterns to minimize your risk of experiencing diarrhea.
Effective Remedies to Manage Diarrhea After Alcohol
Although alcohol-related diarrhea is uncomfortable, it is highly manageable. Below are common effective diarrhea management remedies after a session of heavy drinking:
Hydration and Electrolyte Replacement
Alcohol consumption causes dehydration, which is further accelerated by fluid loss. Therefore, rehydration should be your first remedy. We recommend the following options:
Water: Take plain water to rehydrate effectively.
Coconut water: Coconut water has natural electrolytes. It is also easy on the stomach.
Electrolyte solutions: Try products like Pedialyte and Oral Rehydration Salts to replenish your body’s concentration of Sodium, Potassium, and other minerals.
Do not take caffeine or more alcohol, as both will make you more dehydrated.
Dietary Adjustments
Changing or adjusting your dietary habits for 24-48 hours can help you minimize alcohol-induced diarrhea. Instead of foods with excess dairy, spices, fats, or sugar alcohols, switch to a bland, low-fiber diet. The options below are highly recommended:
Clear broths: Clear, well-prepped broths are both soothing and hydrating.
BRAT: For easier digestion and stool firmness, consider toast, rice, bananas, and applesauce.
You can restore gut health by slowly reintroducing fiber-rich foods once symptoms reduce.
Over-the-Counter Treatments
Some medications and supplements may offer relief. However, always consider professional advice for the best results. Below are a few exceptional options:
Probiotics: Strains like Saccharomyces boulardii and Lactobacillus rhamnosus can help restore your gut’s microbiome balance.
Loperamide: Commonly referred to as Imodium, loperamide can minimize frequent bowel movements. However, you should limit its usage to two days (or less).
You can also try digestive enzymes (subject to professional advice) if you suspect food intolerance may have contributed to your predicament.
Preventing Alcohol-Induced Diarrhea: Tips and Strategies
Alcohol-related diarrhea is both treatable and preventable. You can avoid future episodes through moderation, drinking responsibly, preparing your digestive system, or choosing alcohol wisely. Here is a brief exploration of practical prevention tips and strategies:
Moderation and Responsible Drinking
Drinking moderately (1-2 drinks) can be an effective diarrhea prevention strategy. Responsible practices minimize the risk of both immediate and long-term gut damage. Remember to pace yourself and listen to your body as you consume alcohol.
Choosing Alcohol Wisely
Go for alcoholic drinks or combinations that are less likely to irritate your digestive system, such as the following:
Clear spirits, such as vodka and gin, are mixed with water or club soda
Dry wines. Avoid dessert liquors or sweet wines
Non-carbonated drinks
Drinks without artificial sweeteners or high-sugar mixers
Read ingredient labels if you have known intolerances.
Preparing Your Digestive System
You can avoid or prevent the symptoms we have discussed above by engaging in innovative pre-drinking practices. Therefore:
Eat a balanced meal before drinking: Remember to include lean proteins and complex carbs.
Take a probiotic: Daily probiotic consumption can help you maintain gut health.
Stay hydrated during your drinking session by alternating alcohol with plain water. You can also consider digestive enzyme supplements for sensitive guts.
