Long-Term Effects of Alcohol on the Intestines

What Is the Digestive System?

The digestive system, also known as the gastrointestinal or GI tract, takes in foods and beverages and helps the body break them down. It comprises the following organs:

  • Mouth
  • Esophagus
  • Stomach
  • Small intestine
  • Large intestine (colon)
  • Rectum
  • Anus

These organs also interact with the pancreas, gallbladder, and liver to process solids and liquids. They help the body retain helpful substances that may assist with growth and tissue repair while moving waste out of the body.

What Are the Long-Term Effects of Alcohol on the Digestive System?

The long-term effects of alcohol on the stomach, intestines, esophagus, and other organs may be devastating. Starting at the top of the GI tract, here is a summary of the disastrous effects alcohol has on the entire digestive system.

Gastroesophageal Reflux Disease

Gastroesophageal reflux disease, commonly referred to as GERD, is a common disorder characterized by gastric acid flowing back into the esophagus. It causes a burning sensation in the chest, upper abdominal or chest pain, and difficulty swallowing. Though it may have many causes, alcohol consumption significantly increases the risk, especially long-term heavy drinking.

Alcoholic Gastritis

Alcoholic gastritis is a condition that occurs when beer, wine, or liquor erodes and irritates the stomach lining. In many instances, stronger beverages with higher alcohol by volume (ABV), such as vodka, whiskey, and gin, are most likely to cause gastritis. Common symptoms include fatigue, upper abdominal pain, bloating, and loss of appetite. 


Peptic ulcers are sores that form on the stomach lining and the small intestine’s upper part. When alcohol makes contact with digestive organs, it may cause them to become irritated and inflamed. As a result, ulcer-causing bacteria and chemicals in medications, such as NSAIDs, may have a greater chance of causing sores to develop. Symptoms include burning, nausea, and a feeling of fullness in the stomach.


Alcohol is a corrosive substance that can deteriorate the esophagus, stomach, intestines lining, mouth, and throat. Consequently, cancer-causing toxins may more easily infiltrate the lining of these organs. Additionally, it contains carcinogens, which can cause certain cancers. Those who regularly consume large volumes of beer, wine, or liquor may be more susceptible to developing oral, esophageal, stomach, and colorectal cancer.
