Important differences Between Acute Gastritis and Chronic Gastritis

Acute Gastritis

Acute gastritis is a condition characterized by the sudden inflammation of the stomach lining. It can be caused by various factors, including bacterial or viral infections, certain medications, excessive alcohol consumption, stress, or consuming irritating substances. The inflammation leads to irritation and damage to the stomach lining, resulting in symptoms such as abdominal pain, nausea, vomiting, bloating, and loss of appetite.

One of the common causes of acute gastritis is an infection with the bacterium Helicobacter pylori (H. pylori). This bacterium can live in the stomach and cause inflammation, leading to gastritis. Other infections, such as viral infections, can also trigger acute gastritis. In addition, certain medications like nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin can irritate the stomach lining and contribute to the development of gastritis.

Excessive alcohol consumption is another significant factor that can lead to acute gastritis. Alcohol can irritate and damage the stomach lining, causing inflammation. Stress and emotional factors can also play a role in the development of gastritis, as they can increase stomach acid production and affect the protective mechanisms of the stomach lining.

The symptoms of acute gastritis can vary from mild to severe. Individuals may experience abdominal pain or discomfort, which can range from a dull ache to a sharp, burning sensation. Nausea, vomiting, and bloating are also common, and some individuals may have a loss of appetite or a feeling of fullness after eating small amounts of food. In severe cases, there may be blood in the vomit or stools.

Diagnosis of acute gastritis involves a medical history evaluation, physical examination, and possibly diagnostic tests. Endoscopy, a procedure in which a thin, flexible tube with a camera is inserted into the stomach, may be performed to visualize the stomach lining and assess any signs of inflammation or damage. Biopsy samples may be taken during endoscopy to test for H. pylori infection or other underlying causes.

Treatment of acute gastritis aims to relieve symptoms and promote healing of the stomach lining. This typically involves lifestyle modifications such as avoiding irritating foods, reducing or eliminating alcohol consumption, managing stress, and taking over-the-counter antacids or acid reducers to reduce stomach acid production. If H. pylori infection is present, antibiotics may be prescribed to eradicate the infection.

In most cases, acute gastritis resolves within a few days to weeks with appropriate treatment and lifestyle modifications. However, it is important to seek medical attention if symptoms persist, worsen, or if there are signs of complications such as severe bleeding or persistent vomiting.

Chronic Gastritis

Chronic gastritis is a long-term inflammation of the stomach lining that can persist for months or even years. Unlike acute gastritis, which develops suddenly, chronic gastritis tends to develop gradually over time. It is often caused by the same factors as acute gastritis, including H. pylori infection, long-term use of NSAIDs, excessive alcohol consumption, or autoimmune disorders.

One of the primary causes of chronic gastritis is H. pylori infection. This bacterium can colonize the stomach lining and lead to chronic inflammation. If left untreated, H. pylori infection can cause ongoing damage to the stomach lining, resulting in chronic gastritis. Long-term use of NSAIDs, such as aspirin or ibuprofen, can also contribute to the development of chronic gastritis by irritating the stomach lining.

Excessive alcohol consumption can be another major factor in the development of chronic gastritis. Alcohol irritates and damages the stomach lining, leading to inflammation. Autoimmune disorders, such as autoimmune gastritis, occur when the immune system mistakenly attacks the cells of the stomach lining, causing chronic inflammation.

The symptoms of chronic gastritis may vary from person to person. Some individuals may experience no noticeable symptoms, while others may have recurring or persistent symptoms. Common symptoms include a dull or burning pain in the upper abdomen, bloating, nausea, vomiting, and a feeling of fullness after eating small amounts of food. In severe cases, there may be blood in the vomit or stools.

Diagnosing chronic gastritis involves a combination of medical history evaluation, physical examination, and diagnostic tests. Endoscopy may be performed to visualize the stomach lining and assess the extent of inflammation and damage. Biopsy samples may be taken during endoscopy to test for H. pylori infection or to evaluate the presence of autoimmune disorders.

Treatment of chronic gastritis aims to manage symptoms, reduce inflammation, and prevent complications. Lifestyle modifications, such as avoiding trigger foods, reducing alcohol consumption, and managing stress, are important. In cases of H. pylori infection, a combination of antibiotics and acid reducers may be prescribed to eradicate the infection. In autoimmune gastritis, medications to suppress the immune system may be used.

Managing chronic gastritis requires long-term care and monitoring. Regular follow-up with a healthcare professional is important to assess the effectiveness of treatment, manage symptoms, and monitor for any complications or changes in the condition.
