Acute Gastritis: Understanding the Root Causes & Lifestyle Changes

acute gastritisGastritis is a common medical condition that affects the lining of the stomach. When this condition develops suddenly and lasts for a short period, it is referred to as acute gastritis.

In contrast, chronic gastritis is a long-term condition that persists over a more extended period.
Acute gastritis can cause discomfort and may lead to more severe complications if left untreated.


Understanding the root causes and making necessary lifestyle changes can help manage and prevent this condition effectively.

What Are the Causes of Acute Gastritis?

Acute gastritis can be triggered by various factors, including:

  • Helicobacter pylori infection: One of the most common causes of acute gastritis is the presence of the bacterium Helicobacter pylori in the stomach. This bacterium can lead to inflammation of the stomach lining, resulting in gastritis.
  • NSAIDs: Frequent or prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin or ibuprofen, can cause irritation to the stomach lining, resulting in the development of acute gastritis. It is important to be mindful of the potential gastric effects associated with the extended usage of NSAIDs.
  • Excessive alcohol consumption: Alcohol can irritate the stomach lining, causing inflammation and gastritis.
  • Stress: High levels of stress can trigger gastritis or exacerbate existing symptoms.
  • Autoimmune disorders: In some cases, the body’s immune system can mistakenly attack the stomach lining, leading to acute gastritis.

What Are the Symptoms of Acute Gastritis?

Acute gastritis can present various symptoms, which may include:

  • Stomach pain and discomfort: The most common symptom of acute gastritis is a burning or gnawing pain in the upper abdomen. This pain may be mild to severe and can worsen after eating.
  • Nausea or vomiting: Gastritis can induce nausea and, in certain instances, result in vomiting. These unpleasant symptoms of gastric inflammation can manifest as feelings of queasiness and may lead to the expulsion of stomach contents.
  • Indigestion: Individuals with acute gastritis may experience bloating, belching, and a feeling of fullness in the stomach.
  • Loss of appetite: Gastritis can lead to a reduced desire to eat due to the discomfort it causes.
  • Black or tarry stools: In some cases, acute gastritis can lead to bleeding in the stomach, resulting in dark or tarry stools.

Diagnosing Acute Gastritis

To diagnose acute gastritis, a healthcare provider may perform the following:

  • Medical history and physical examination: The doctor will inquire about the patient’s symptoms and medical history and conduct a physical examination.
  • Endoscopy: An endoscopy is a procedure in which a thin, flexible tube with a camera is inserted into the stomach to examine the lining and identify signs of inflammation.
  • 3Biopsy: During endoscopy, the doctor may take a small tissue sample (biopsy) from the stomach lining for further examination.

Potential Complications of Untreated Acute Gastritis

If left untreated, acute gastritis can lead to more severe complications, including:

  • Peptic ulcers: The inflammation caused by gastritis can result in the development of open sores in the stomach lining.
  • Gastrointestinal bleeding: Severe gastritis can lead to bleeding in the stomach, which can be life-threatening if not addressed promptly.
  • Anemia: Chronic bleeding from gastritis can lead to a decrease in red blood cells, causing anemia.
  • Gastric cancer: Although rare, chronic untreated gastritis can increase the risk of developing stomach cancer.

Treatment of Acute Gastritis

The treatment of acute gastritis typically involves the following:

  • Medications: Proton pump inhibitors (PPIs) and antacids can help reduce stomach acid and alleviate symptoms.
  • Antibiotics: If Helicobacter pylori infection is present, a course of antibiotics may be prescribed to eliminate the bacterium.
  • Avoiding irritants: Individuals with acute gastritis should avoid NSAIDs, alcohol, and other substances that can irritate the stomach lining.

Lifestyle Modifications for Acute Gastritis


In addition to medical treatment, lifestyle changes can play a crucial role in managing acute gastritis. Some helpful modifications include:

Dietary Recommendations:

  • Foods to avoid: Spicy, fatty, and acidic foods can worsen gastritis symptoms and should be avoided. Carbonated beverages, caffeine, and chocolate should also be limited.
  • Foods that may help soothe the stomach: Consuming a bland diet that includes bananas, applesauce, plain rice, and boiled potatoes can help alleviate stomach discomfort.

Managing Stress and Anxiety:

  • Stress management techniques, such as deep breathing exercises, meditation, and yoga, can help reduce stress levels and prevent gastritis flare-ups.

Avoiding Alcohol and Tobacco:

  • Eliminating or reducing alcohol consumption and quitting smoking can significantly improve gastritis symptoms and promote stomach healing.

Importance of Adequate Hydration:

  • Drinking enough water is essential for maintaining stomach health and preventing dehydration, especially if vomiting occurs.


Acute gastritis can be a painful and discomforting condition, but it can be managed effectively with appropriate medical treatment and lifestyle changes.

By understanding the root causes of acute gastritis and making the necessary adjustments in diet and daily habits, individuals can minimize symptoms, prevent complications, and maintain a healthy stomach. If you experience persistent stomach pain or other symptoms of gastritis, seeking medical attention for proper diagnosis and treatment is crucial.
