Poop Black After Drinking Red Wine

If you are one of those who love taking red wine, this might be news, but is it excellent news?

According to studies, the alcohol from red wine can irritate the walls of your intestine, causing diarrhea and black stool. Why does this happen?

Let’s find out…

Can Red Wine Change My Poop Color?

Red wine has many effects on your body system, both short-term and long-term impact, particularly from its alcohol content.

Some of these effects are how it alters your digestion, unsettles your guts, and breaks down nutrients in the body.

In which, all of this collectively affects your bowel movement.

Red wine makes the immune system weak and causes inflammation.

This could later develop into or increase the symptoms associated with a condition called inflammatory bowel disease—a disease condition characterized by the inflammation of the gastrointestinal tract.

Individuals with a disease like IBS, Inflammatory bowel syndrome, are advised to lower their intake of red wine, alcohol, and other substances that could irritate the walls of the intestine.

The inflammation does not just occur alone; it comes with unpleasant symptoms, one of which is the change in your poop color.

The significant signs associated with this inflammation are abdominal pain, drastic weight loss, fatigue, persistent diarrhea, rectal bleeding, or bloody stool.

The effect of red wine worsens such symptoms in people suffering from the disease and can also be a secondary cause for the irritation of the digestive tract.

When you notice, your poop color deviates from the regular shade of brown to green, black, red, and even blue.

It is possible that the constant conceptions of red caused this wind. Substances we take in, including alcohol, can change stool color.

Black Poop From Red wine, What Does It Indicate?

Your poop color could show different things; as much as the foods you eat can determine your stool color, your stool color can also mean that there is a problem.

Odd poop color could show an adverse health condition, and most of these conditions are easily aggravated by alcohol consumption.

Internal bleeding is the primary causative factor that changes your poop color to black, appearing like used coffee grounds.

This can occur when your upper or lower digestive tract areas are irritated, causing blood to mix with your stool.

Some illnesses associated with black poop color include:

Cancer Of The Digestive System

Cancer of the digestive system is a condition that shows the growth of cancerous cells in the stomach’s lining.

It is usually accompanied by intense vomiting, bloody stool, fatigue, loss of appetite, and other related conditions, showing an inflamed gastrointestinal tract.

Colitis: Inflammation Of The Colon

Colitis is also an inflammation or irritation of the colon.

Common colitis symptoms also include abdominal pain, cramps, bloating, unexpected weight loss, blood in the stool, or dark poop.


This is an infection that also involves inflammation and pouches that form in the large intestine.

These pouches are typically not harmful; however, when they get inflamed, they become dangerous.

They can lead to bowel obstruction, diarrhea, constipation, bloody stool, and so many other GIT problems.

Constant alcohol consumption has been linked to the causes of this disease, and your red wine can be the reason for your black stool.

Although these conditions are a sign that there could be more health problems, alcohol is also known to be a secondary cause of most of these diseases.

An individual with any of these disease conditions is strongly advised against the intake of alcohol.

Chronic alcoholics are also advised to reduce alcohol intake because it could lead to such diseases.

Why Is My Poop Black After Drinking Alcohol?

Long-term alcohol abuse is one of the major factors that trigger irritation of the bowels.

Chronic alcohol consumption, especially over a long period, can lead to an imbalance in the guts.

This condition of imbalance is known as Dysbiosis. It messes up the balance of good and bad bacteria in the guts, stimulating the growth of more harmful bacteria that can further disrupt GIT health.

If this persists, the intestine walls get leaky and sometimes perforated, meaning toxins and bacteria will get into the bloodstream and other organs.

When this inflammation becomes consistent, you may experience chronic diarrhea and erratic bowel movement.

Without medical intervention, this inflammation destroys the cells lining the colon, causing more problems in the gastrointestinal tract.

Sores and ulcers may develop, causing dark poop or bloody diarrhea.

Although studies have consistently shown that the consumption of red wine is less associated with diseases like heart disease.

We still cannot overrule the fact that alcohol is one of its major components.

Typically, red wine would have 12-25% alcohol content, and if taken excessively, can cause as much damage as any other alcohol would.

We have done so much justice in explaining the correlation between your alcohol intake, inflammation, and bloody stool.

You should know how much effect alcohol can have on your digestive system. Black poop after red wine is not unusual, especially if you take so much of it.

The alcohol present in it gets to your bloodstream, causing inflammation and damages to the intestinal lining.

Alcohol affects the bowel movement, causes dehydration, worsens symptoms of inflammatory bowel syndrome, leading to internal bleeding.

This whole situation, if it is not treated, will lead to the excretion of black poop.

How To Stop Black Poop After A Red Wine

Asides from the changes in mood, dizziness, nausea, and headaches you get when you consume a lot of alcohol from your red wine, your poop color will also suffer some drastic changes.

Alcohol is a toxin, one that does a lot of damage to your intestinal health. However, there are ways you can reduce these effects or eliminate them.

These solutions range from medical interventions to lifestyle and dietary changes. Let us look at how these methods can help you stop black poop after your red wine intake.

Dietary modifications

What you eat and drink aside from taking red wine can also play an essential role in the health changes in your body.

Alcohol is a major cause of dehydration; whenever you take in alcohol, you can soften the effect of the alcohol by—drinking a lot of water m.

Staying hydrated can help you counteract the effect of dehydration that you will get from the alcohol.

Also, before you take in alcohol, health experts recommend you take in enough foods to reduce the irritation in the lining of your stomach.

Fruits like bananas, whole grains, rice, foods rich in protein, and enough water are highly recommended. Foods to avoid when you take in red wine include:

  • Spicy foods
  • Dairy products
  • Caffeinated beverages
  • Highly seasoned foods e.t.c

Lifestyle modifications

Drinking in moderation is an option for ways to soften the effect of alcohol on your body system.

The standard rate of red wine intake in adults is 5 ounces per day.

Anything exceeding that is excessive and would cause a lot of damage to your gastrointestinal tract. When you decide to take red wine, do so in moderation.

Avoid mixing your red wine with other substances like caffeine, artificial sugar, or substances that are not equally healthy.

Try not to drink on an empty stomach, stay hydrated and avoid drinks high in sugar.

Medical Intervention

Diseases like colitis, diverticulitis, cancer of the digestive system, and many other gastrointestinal disorders would require medical intervention.

If your bloody stool continues to occur even after trying some modifications listed above, seek medical care.

Some of these conditions can be treated with OTC medications, anti-inflammatory drugs, antibiotics, immune system suppressors, and many others.

Your physician will make necessary prescriptions, depending on the severity of your illness.

Some GIT diseases, however, cannot be treated without the aid of surgical intervention. Some treatment is considered when other methods prove futile.

If you notice extreme changes in your intestinal tract, reach out to your doctor or any trusted health care practitioner.

Bottom Line

With red wine or alcohol consumption, moderation is key. We have already discussed how much damage alcohol can do to your overall health.

Drink in moderation, stay hydrated always and try as much as you can to keep your digestive system free from toxic substances.

Last, if your bloody stool persists, do not treat it at home; take a trip down to the nearest hospital around you.

The professionals are ready to work out a permanent solution to your black poop.
