What is Gastritis?

Gastritis is an inflammation of the stomach lining that can be acute or chronic. Acute gastritis starts suddenly and is usually short-lived, while chronic gastritis can develop slowly and last for a long time. Historically, the term gastritis was first used in the 19th century, when doctors began to understand the inflammatory processes of the stomach. Gastritis is significant because it can lead to complications such as stomach ulcers and bleeding if not properly treated. Today, gastritis is a common condition that affects many people around the world. It can reduce quality of life by causing pain and discomfort, and it can also be a sign of more serious gastrointestinal problems. Modern medicine has significantly developed diagnostic and treatment methods, making it possible to effectively manage gastritis and prevent complications.

Causes of gastritis

Gastritis can be caused by various factors that affect the stomach lining. Understanding these causes is important for effective treatment and prevention.

Most common causes

• Helicobacter pylori infection: This bacterium is the most common cause of gastritis, responsible for most cases of chronic gastritis. It secretes urease, which neutralizes stomach acid and allows the bacterium to survive in the acidic environment of the stomach, causing inflammation. H. pylori infection is common and is considered one of the main risk factors for gastrointestinal diseases. Studies show that this bacterium can cause a variety of stomach pathologies, from mild mucosal inflammation to severe ulcers and stomach cancer. Eradication of H. pylori is therefore an essential goal of treatment, which can significantly reduce the risk of associated complications.
• Alcohol consumption: Excessive alcohol consumption can irritate and damage the lining of the stomach, causing gastritis.Alcohol can cause direct damage to the stomach lining, increase acid production and promote inflammation. Therefore, it is recommended that patients with gastritis limit alcohol consumption or completely avoid it in order to prevent exacerbation of symptoms.
• Autoimmune gastritis: In this case, the body's immune system attacks the stomach cells, causing inflammation.Autoimmune gastritis is a less common but important type of gastritis that can be associated with other autoimmune disorders such as pernicious anemia. In this case, the immune system mistakenly attacks the parietal cells of the stomach, which produce the acid and intrinsic factor necessary for the absorption of vitamin B12. This can lead to vitamin B12 deficiency and symptoms such as fatigue, anemia and neurological disorders.
• Stress factors: Physical stress, such as surgery, burns or severe illness, can contribute to the development of gastritis.Stress-induced gastritis, also known as stress ulcers, often occurs during times of intense physiological stress, which can cause decreased blood flow to the gastric mucosa and increased acid secretion. In such cases, prophylactic treatment with antacids may be necessary to prevent severe mucosal damage.

Infection with Helicobacter pylori

Helicobacter pylori is a spiral-shaped, gram-negative bacterium that colonizes the gastric mucosa and causes inflammation. The infection is usually acquired in childhood and can last for years if left untreated. H. pylori causes gastritis by releasing enzymes and toxins that damage the stomach lining and stimulate the immune system's response. The presence of this bacterium is also associated with the development of gastric ulcers and gastric cancer, making its eradication an essential goal of treatment.

The prevalence of H. pylori infection is high, especially in developing countries. Transmission occurs mainly through the oral-oral and fecal-oral routes, indicating the importance of hygiene and sanitation in prevention. Thorough hand washing and avoiding contaminated food and water are important preventive measures.

Lifestyle factors

Lifestyle factors such as alcohol consumption, smoking and stress greatly affect the development of gastritis. Alcohol irritates and damages the stomach lining, while smoking reduces the protective capacity of the stomach lining and increases the secretion of stomach acid. Stress can contribute to the development of gastritis by changing the balance of gastric acid secretion and gastric mucus production. Changing your lifestyle can be an effective way to reduce the symptoms of gastritis and prevent it from developing.

Symptoms of gastritis

Symptoms of gastritis depend on whether the condition is acute or chronic and can vary greatly between patients.

Symptoms of acute gastritis

Acute gastritis causes sudden symptoms that can be quite severe. Typical symptoms include:

• Pain or discomfort in the upper abdomen
• Nausea and/or vomiting
• A feeling of fullness after eating

Symptoms of chronic gastritis

Chronic gastritis develops more slowly, and symptoms may be milder but last longer. These include:

• Abdominal discomfort or pain that may worsen after eating
• Constant nausea
• Loss of appetite
• Relapse symptoms

Chronic gastritis can often be asymptomatic, especially in the early stages, which makes early diagnosis difficult without medical examination. In some cases, chronic gastritis can cause progressive mucosal atrophy and metaplasia, which increases the risk of gastric cancer. Therefore, it is important to have regular medical examinations, especially for patients with risk factors.

Diagnostic methods

Diagnosing gastritis is based on a combination of clinical examination and laboratory tests. An accurate diagnosis is important for developing an effective treatment plan.

Endoscopy

Endoscopy is the main method for direct visualization of the gastric mucosa. During the procedure, a flexible tube with a camera is inserted through the patient's mouth, which allows the doctor to view the inside of the stomach. Endoscopy can reveal mucosal inflammation, ulcers and other structural changes. In addition, a biopsy is performed to check for the possible presence of H. pylori and to assess the degree of inflammation.

Endoscopy is particularly useful in differentiating gastritis from other types of gastric pathology, such as peptic ulcers or malignancies. Removal of the biopsy allows for histological analysis, which can help determine the type and severity of inflammation, as well as identify any precancerous changes.

Blood and stool tests

Blood tests can reveal anemia, which can be caused by prolonged bleeding from gastritis. Specific blood tests can also detect H. pylori antibodies, although this method is not as accurate as other tests. Stool tests can detect H. pylori antigens and signs of gastrointestinal bleeding. Both tests are non-invasive and can be useful for the initial diagnosis of gastritis and for evaluating the effectiveness of treatment.

The fecal antigen test is particularly useful in evaluating the effectiveness of H. pylori eradication therapy because it can accurately determine the presence or absence of infection after treatment. A blood test can also detect vitamin B12 deficiency, especially in patients with autoimmune gastritis, which may indicate the need for B12 supplementation.

Urease test

The urease test is another method to detect the presence of H. pylori. This includes analyzing the patient's breath after using the urea solution. If the bacterium is present, it breaks down the urea, releasing carbon dioxide, which is measured in the exhaled breath.

This test is simple, rapid, and noninvasive, making it a popular choice for H. pylori diagnosis and subsequent treatment evaluation. The urease test is also highly specific and sensitive, making it a reliable method for detecting infection.

Treatment options

Treatment for gastritis aims to reduce inflammation of the stomach lining, eradicate infection such as H. pylori, and relieve symptoms.

Lifestyle changes

Lifestyle adjustments are essential for both treatment and prevention. Recommendations include:

• Diet correction: avoiding spicy, fatty and very acidic foods that can irritate the stomach. Food choices can significantly affect gastritis symptoms. It is recommended to choose easily digestible, less irritating foods, such as cooked vegetables, lean meat and whole grain products. Frequent, small portions can reduce the burden on the stomach and help control symptoms.
• Quitting alcohol and smoking: ending these habits can reduce the symptoms of gastritis and prevent it from getting worse. Quitting alcohol and smoking not only helps reduce gastritis symptoms, but also improves overall health by reducing the risk of other gastrointestinal and cardiovascular diseases.
• Stress reduction: Relaxation and stress management techniques such as meditation and yoga can help reduce symptoms. Managing stress is important in the treatment of gastritis, as stress can exacerbate symptoms and cause relapses. Integrating psychological support and relaxation techniques into daily life can improve a patient's overall well-being.

These changes can significantly improve the patient's quality of life and reduce the risk of recurrence of gastritis. Lifestyle adjustments should be made individually in consultation with a healthcare professional.

Nutritional supplements and alternative therapy

Some patients use nutritional supplements, such as probiotics, to balance the gut microflora and relieve symptoms. Although the evidence for the effectiveness of these methods is limited, they may provide relief for some patients.

Prevention

Preventive measures can significantly reduce the risk of developing gastritis. Recommendations include:

• Wash your hands regularly to prevent the spread of H. pylori infection.
• Avoid excessive alcohol consumption and smoking.
• Maintain a balanced diet and a healthy lifestyle that includes stress-reducing activities.

Prevention not only helps prevent the development of gastritis, but also reduces the risk of complications and promotes overall stomach health. A healthy lifestyle that includes a balanced diet, regular exercise, and adequate sleep can improve immune function and reduce the risk of gastrointestinal disease.
