Diverticulitis and Alcohol Use: All You Need to Know
Listen to this article

Alcohol is often a part of social settings, but chronic or heavy drinking is known to cause damage and health problems [1]. But is alcohol bad for diverticulitis? Does it worsen the condition? Here’s what you need to know. 

Can Alcohol Cause Diverticulitis?

Alcohol use is known to increase the risk for diverticular disease and negatively impacts colon health [2-5].

There are three forms of diverticular disease [2]:

  • Diverticulosis: Part of the colon bulges outward and creates a pouch.
  • Diverticulitis: The pouches become inflamed and infected.
  • Diverticular bleeding: The pouches burst and bleed.

The condition is common — over half of people in the United States over age 60 will develop it [2]. The exact cause of diverticular disease is unknown, but experts think it’s likely a combination of genetics, low-fiber diet, lack of exercise, obesity, and excessive alcohol use [3].

Heavy drinking and chronic alcohol use are significant risk factors. Alcohol drinkers are twice as likely to develop diverticulosis than nondrinkers, and those who drink 30 grams of alcohol per day, or two drinks per day, have an increased risk [4, 5].

How Does Alcohol Affect Diverticulitis?

The link between diverticulosis and alcohol and diverticulitis and alcohol isn’t clear, but health experts suggest it’s related to slow motility in the lower colon. [6] Alcohol interferes with the muscles in the colon and may weaken and slow muscle contractions [7]. 

With fewer and weaker contractions, overall bowel movement slows, and stool becomes compacted, increasing pressure [7]. Higher pressure causes weak areas to bulge outward, and the compacted stool may cause diarrhea [7].

The slower movement may also cause stool or bacteria to get stuck in one of the pouches, leading to inflammation and, eventually, infection. The result is diverticulitis [2].

Does Alcohol Make Diverticulitis Worse?

Alcohol increases your risk for diverticulosis and may increase pressure in your colon. However, does alcohol aggravate diverticulitis or trigger symptoms? It may. 

Alcohol damages your stomach and gut lining, causing irritation and inflammation [7]. You might experience symptoms similar to a diverticulitis infection after drinking too much alcohol, such as [8, 9]:

  • Pain
  • Nausea
  • Vomiting
  • Bloating
  • Gas
  • Loss of appetite

If you’re experiencing a diverticulitis flare-up, drinking alcohol may aggravate your symptoms [10]. So, should you or can you drink alcohol with diverticulitis? It’s best to avoid it during a flare-up and reduce your overall intake. 

Other Implications

Alcohol may cause other health conditions, such as colorectal cancer. According to studies, moderate to heavy drinking causes a 1.5-fold increased risk of cancer in the colon and rectum compared to no alcohol use [11] .

In addition, diverticulitis infections may increase your risk of cancer. A study found that patients with diverticular disease had a 33% higher risk of overall cancer and an increased risk for colon cancer [12]. However, diverticulitis and colon cancer have similar symptoms, so it’s possible to misdiagnose or mistake one for the other [13].

Scientific studies show that diverticulitis infections may increase your risk of colorectal cancer [12].

Colonox FIT is an at-home stool test kit that detects hidden blood in stool with clinical precision. Hidden blood in stool may be a sign of several GI disorders, including diverticulitis and colorectal cancer. USPTF recommends annual screening of adults between 45-75 years with a FIT test.

Diagnox and GI Screening

Regular gastrointestinal screening may help you monitor your gut health and identify possible early symptoms of diverticulitis or colorectal cancer. The Colonox FIT by Diagnox is a medical-grade stool test that detects hidden blood in your stool, helping you track signs of GI disorders from the comfort of your home for earlier follow-up with your doctor.
