Is Diverticulitis and Acid Reflux Related? A Comprehensive Answer

Diverticulitis and acid reflux are two common digestive disorders that affect millions of people worldwide. But are they related? Can one cause the other? And how can you manage both conditions effectively? In this article, we will explore the possible links between diverticulitis and acid reflux, as well as the symptoms, causes, treatments and prevention strategies for both.

What is Diverticulitis?

Diverticulitis is a condition that occurs when small pouches (diverticula) in the colon wall become inflamed or infected. These pouches are usually harmless and do not cause any symptoms, but they can become problematic if they rupture or get blocked by fecal matter. This can lead to abdominal pain, fever, nausea, vomiting, constipation or diarrhea. According to Mayo Clinic, diverticulitis can also cause serious complications, such as abscesses, fistulas, bowel obstruction or perforation.

What is Acid Reflux?

Acid reflux, also known as gastroesophageal reflux disease (GERD), is a condition that occurs when stomach acid flows back up into the esophagus, the tube that connects the mouth to the stomach. This can cause a burning sensation in the chest, throat or mouth, as well as regurgitation, coughing, hoarseness, sore throat or difficulty swallowing. According to CGAA, acid reflux can also damage the lining of the esophagus and increase the risk of esophageal cancer.

Are Diverticulitis and Acid Reflux Related?

There is no clear evidence that diverticulitis causes acid reflux, or vice versa. However, some factors may increase the risk of developing both conditions, such as:

  • Aging. The incidence of diverticulitis and acid reflux increases with age, as the muscles and tissues of the digestive system become weaker and less elastic.
  • Obesity. Being overweight puts extra pressure on the abdomen, which can affect the function of the lower esophageal sphincter (LES), the valve that prevents stomach acid from escaping into the esophagus. It can also increase the inflammation and infection of the diverticula.
  • Smoking. Smoking cigarettes can irritate the lining of the esophagus and the colon, as well as weaken the LES and impair the healing of the diverticula.
  • Lack of exercise. Physical activity can improve the motility and tone of the digestive system, as well as reduce stress and inflammation, which can benefit both diverticulitis and acid reflux.
  • Diet. Eating a diet high in animal fat and low in fiber can contribute to both diverticulitis and acid reflux, as it can slow down the digestion and increase the production of stomach acid. On the other hand, eating a diet rich in fruits, vegetables, whole grains and lean proteins can provide fiber, antioxidants and anti-inflammatory compounds that can protect and heal the digestive system.

How to Treat Diverticulitis and Acid Reflux?

The treatment of diverticulitis and acid reflux depends on the severity and frequency of the symptoms, as well as the presence of any complications. Some of the common treatment options include:

  • Medications. Antibiotics can be prescribed to treat the infection and inflammation of the diverticula. Antacids, H2 blockers and proton pump inhibitors can be used to neutralize, reduce or block the production of stomach acid, respectively. Prokinetics can be used to improve the movement of the stomach and the esophagus. Painkillers, anti-inflammatory drugs and antispasmodics can be used to relieve the pain and cramps associated with both conditions.
  • Surgery. In some cases, surgery may be required to remove the diseased or perforated part of the colon (colectomy) or the esophagus (esophagectomy). Surgery can also be performed to repair the LES (fundoplication) or create a new valve between the stomach and the esophagus (LINX device).
  • Lifestyle changes. Making some changes in the diet and habits can help prevent or reduce the symptoms and complications of both diverticulitis and acid reflux. Some of the recommended changes include:
    • Eating smaller, more frequent meals and avoiding foods that trigger or worsen the symptoms, such as spicy, fatty, acidic, fried or carbonated foods, alcohol, caffeine, chocolate, mint, garlic, onion and tomato.
    • Drinking plenty of water and avoiding dehydration, which can worsen the constipation and the acid reflux.
    • Losing weight if overweight or obese, and maintaining a healthy body mass index (BMI).
    • Quitting smoking and avoiding exposure to secondhand smoke, which can irritate and damage the digestive system.
    • Exercising regularly and moderately, and avoiding strenuous or vigorous activities that can increase the abdominal pressure or the reflux.
    • Elevating the head of the bed by 6 to 8 inches, and sleeping on the left side, which can help gravity keep the stomach acid in the stomach and prevent it from flowing back into the esophagus.
    • Wearing loose-fitting clothes and avoiding belts, tight pants or anything that can constrict the abdomen and the stomach.
    • Managing stress and practicing relaxation techniques, such as deep breathing, meditation, yoga or massage, which can reduce the production of stomach acid and the inflammation of the diverticula.


Diverticulitis and acid reflux are two common digestive disorders that can cause significant discomfort and distress. While they are not directly related, they can share some risk factors and symptoms, and they can affect each other indirectly. Therefore, it is important to consult a doctor if you experience any signs or symptoms of either condition, and to follow the appropriate treatment and prevention strategies. By doing so, you can improve your digestive health and your quality of life.
