What is Gastritis?

Definition of Gastritis

Gastritis refers to the inflammation of the lining of the stomach. This condition can occur suddenly, known as acute gastritis, or it can be a long-lasting condition, referred to as chronic gastritis. The inflammation in the stomach lining can cause a range of symptoms and can be caused by various factors, such as bacterial infections, chronic use of nonsteroidal anti-inflammatory drugs (NSAIDs), excessive alcohol consumption, stress, and autoimmune disorders.

Types of Gastritis

There are different types of gastritis, each having its own underlying causes and characteristics. Some common types of gastritis include:

  1. Acute Gastritis: This type of gastritis occurs suddenly and is usually caused by factors like bacterial infections, excessive alcohol consumption, or NSAID use. It often resolves on its own with appropriate treatment and lifestyle changes.

  2. Chronic Gastritis: Chronic gastritis is a long-lasting inflammation of the stomach lining. It can result from ongoing irritants like Helicobacter pylori (H. pylori) infection, autoimmune disorders, or certain medications. Chronic gastritis may require more specialized treatment to manage symptoms and prevent further complications.

  3. Erosive Gastritis: Erosive gastritis is characterized by the erosion or damage to the stomach lining. It can be caused by long-term NSAID usage, excessive alcohol consumption, or certain diseases like Crohn’s disease.

  4. Atrophic Gastritis: Atrophic gastritis occurs when the stomach lining starts to thin and lose its normal function. It is often associated with chronic infection by H. pylori or autoimmune disorders.

Understanding the types of gastritis can help determine the most appropriate treatment approach and management strategies. It is essential to consult a healthcare professional for an accurate diagnosis and personalized treatment plan.

Causes of Gastritis

Gastritis can be caused by various factors, ranging from infections to lifestyle choices. Identifying the underlying cause is crucial for effective treatment and prevention of gastritis. Here are some common causes:

Bacterial Infections

One of the leading causes of gastritis is an infection with the bacteria Helicobacter pylori (H. pylori). This bacterium affects the stomach lining and can lead to chronic inflammation. H. pylori is commonly acquired during childhood and can persist for years if left untreated. Poor hygiene, contaminated food or water, and close contact with infected individuals can contribute to its spread.

Chronic Use of NSAIDs

Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen, and naproxen, are commonly used to manage pain and reduce inflammation. However, long-term or excessive use of these medications can damage the lining of the stomach and trigger gastritis.

Excessive Alcohol Consumption

Excessive alcohol consumption can irritate the stomach lining and lead to gastritis. Alcohol increases the production of stomach acid, which can cause inflammation and damage to the stomach lining over time. It is essential to moderate alcohol intake to prevent gastritis and other related health issues.

Stress and Anxiety

Stress and anxiety, while not direct causes of gastritis, can contribute to its development and exacerbation of symptoms. Prolonged or chronic stress can lead to changes in stomach acid production, blood flow to the stomach, and the overall function of the digestive system. These changes can increase the risk of developing gastritis or worsen existing symptoms.

Autoimmune Disorders

In some cases, gastritis may be caused by autoimmune disorders, where the immune system mistakenly attacks the cells of the stomach lining. Conditions like autoimmune gastritis or pernicious anemia can lead to chronic inflammation and damage to the stomach lining. These conditions often require specialized treatment and ongoing management.

Understanding the causes of gastritis can help individuals make necessary lifestyle changes and seek appropriate medical interventions to prevent or manage this condition effectively.

Understanding Gastritis: Causes, Symptoms, and Treatment

Symptoms of Gastritis

Gastritis can present with a variety of symptoms, which can vary in severity and duration. It is important to recognize these symptoms and seek medical attention for proper diagnosis and treatment. Here are some common symptoms of gastritis:

Abdominal Pain

Abdominal pain or discomfort is one of the most common symptoms of gastritis. It is usually described as a burning or gnawing sensation in the upper abdomen. The pain may be worse after eating or while on an empty stomach.

Nausea and Vomiting

Gastritis can cause feelings of nausea and may lead to vomiting in some cases. The severity of these symptoms can vary, and they may be triggered by certain foods or medications.


Indigestion, also known as dyspepsia, is another common symptom of gastritis. It may manifest as a feeling of fullness, bloating, or discomfort in the upper abdomen after eating. Indigestion may also be accompanied by burping or gas.

Loss of Appetite

Gastritis can result in a decreased appetite, leading to a reduced desire to eat. This can be due to the discomfort and pain associated with gastritis or as a result of the inflammation affecting the normal functioning of the stomach.

Bloating and Gas

Excess gas and bloating can occur with gastritis, leading to discomfort and a feeling of fullness. This can be caused by the accumulation of gas in the stomach or changes in the digestive process due to inflammation.

Burning Sensation in the Stomach

Many individuals with gastritis experience a burning sensation in the stomach, also known as heartburn. This sensation can be felt in the upper abdomen and may worsen after eating certain foods or lying down.

These symptoms can vary in intensity and may come and go. Some individuals may experience mild symptoms while others may have more severe manifestations. It is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment.

Diagnosing Gastritis

Diagnosing gastritis involves a comprehensive evaluation of medical history, physical examination, and various diagnostic tests. This process helps healthcare professionals determine the underlying cause and severity of gastritis, enabling them to develop an effective treatment plan. Here are some common diagnostic methods for gastritis:

Medical History Evaluation

A detailed medical history assessment is crucial for diagnosing gastritis. The healthcare provider will inquire about symptoms, medical conditions, medications, and dietary habits. They may also ask about the presence of risk factors, such as a history of H. pylori infection or autoimmune disorders.

Physical Examination

During a physical examination, the healthcare provider may palpate the abdomen to check for tenderness or swelling. They may also assess for signs of anemia or other complications associated with gastritis.

Blood Tests

Blood tests can help determine the presence of H. pylori infection, assess the levels of stomach acid, and detect signs of anemia or other underlying conditions. These tests may include a complete blood count (CBC), testing for H. pylori antibodies, and measurement of certain proteins and enzymes.

Stool Tests

Stool tests may be conducted to detect the presence of H. pylori antigens or signs of gastrointestinal bleeding. These tests can provide valuable information about the underlying cause of gastritis.

Upper Endoscopy

Upper endoscopy, also known as esophagogastroduodenoscopy (EGD), is a procedure that allows direct visualization of the stomach and upper digestive tract. During this procedure, a thin, flexible tube with a camera at the end is inserted through the mouth and into the esophagus, stomach, and small intestine. This allows the healthcare provider to examine the stomach lining and take biopsies if necessary.


If abnormalities or suspicious areas are detected during an upper endoscopy, the healthcare provider may perform a biopsy. This involves taking small tissue samples from the stomach lining for further examination under a microscope. Biopsies help confirm the diagnosis, identify the type of gastritis, and rule out other conditions.

These diagnostic methods help healthcare professionals determine the cause and severity of gastritis, enabling them to develop an individualized treatment plan. It is essential to seek medical evaluation if experiencing symptoms of gastritis or if there is a concern about potential underlying causes.
