Gastritis presents with various symptoms, the most common of which is pain in the upper middle part of the abdomen. In some cases, this pain may be felt in the upper left area of the stomach. In severe cases, the discomfort can radiate to the back, making it difficult to pinpoint the source.

In addition to abdominal pain, those with gastritis may experience the following symptoms:

1. Bloating. The stomach may feel swollen or tight due to gas or inflammation.
2. Vomiting blood. This symptom, also called hematemesis, can indicate severe damage to the stomach lining.
3. Dark or bloody stools. Known as melena, this may suggest internal bleeding in the stomach or upper intestines.
4. Yellow or green substances in vomit. This coloration is often due to bile, which can be present in vomiting caused by stomach irritation.
5. Fever. In some cases, fever may accompany gastritis, especially if an infection is present.
6. Dizziness and fainting. Blood loss and dehydration from gastritis can lead to weakness, dizziness, or fainting episodes.
7. Rapid heartbeat. This may occur as the body attempts to compensate for blood loss or dehydration.
8. Excessive sweating. Profuse sweating can also accompany intense pain or shock from severe symptoms.
9. Shortness of breath. When internal bleeding or severe anemia occurs, breathing may become labored.

It’s important to note that not all cases of gastritis exhibit noticeable symptoms. In many cases, the condition can be silent or only mildly symptomatic, which is why routine checkups can be beneficial in detecting and managing gastritis early on.

Types of Gastritis

There are different types of gastritis, each with distinct causes. The main types are as follows:

1. Type A gastritis. This form is caused by an autoimmune condition where the body attacks the cells in the stomach lining. This immune system dysfunction can increase the risk of developing stomach cancer, anemia, or vitamin B12 deficiency. Often referred to as autoimmune gastritis, this type disrupts the stomach’s ability to produce certain essential nutrients, potentially leading to chronic health issues.
2. Type B gastritis. This is the most common type of gastritis and is caused by the bacterium Helicobacter pylori (H. pylori). H. pylori infection can lead to inflammation, stomach and duodenal ulcers, and even stomach cancer if left untreated. This bacteria is typically acquired in childhood and may remain dormant for years, causing symptoms later in life.
3. Type C gastritis. Known as chemical or reactive gastritis, this type is caused by prolonged exposure to irritants that damage the stomach lining, such as nonsteroidal anti-inflammatory drugs (NSAIDs), bile reflux, and excessive alcohol consumption. Type C gastritis can result in stomach bleeding and compromise the stomach lining’s protective barrier, leading to chronic inflammation.

Additional forms of gastritis include hypertrophic gastritis, caused by a deficiency in protein, leading to thickened stomach folds, and eosinophilic gastritis, which may be associated with allergic conditions like eczema or asthma. These forms are rarer and may involve additional immune or nutritional factors.

Understanding these types of gastritis and their causes can aid in choosing effective treatments and preventive measures, as each type requires a different approach to management.

Diagnostic Procedures for Gastritis

Diagnosing gastritis involves identifying the underlying causes of stomach inflammation and assessing the extent of damage to the stomach lining. Here are some common diagnostic procedures used to diagnose gastritis:

1. Medical history and physical examination
   

   The initial diagnostic step includes reviewing the patient’s medical history and symptoms. Doctors may ask about diet, medication use (particularly NSAIDs), alcohol consumption, stress levels, and any recent illnesses. A physical exam is performed to identify signs of pain, tenderness, or other symptoms indicative of gastritis.

2. Endoscopy
   

   An upper endoscopy is often the most direct way to diagnose gastritis. In this procedure, a thin, flexible tube with a camera is inserted through the mouth to visualize the esophagus, stomach, and duodenum. The doctor can observe any inflammation, redness, or damage to the stomach lining. Small tissue samples (biopsies) may also be taken for further testing, especially to check for H. pylori infection.

3. Stool test
   

   A stool test may be conducted to detect the presence of blood in the stool, which can indicate internal bleeding caused by gastritis. This test can also identify H. pylori antigens, suggesting a bacterial infection linked to gastritis.

4. Blood tests
   

   Blood tests help detect signs of infection, anemia, or inflammation, all of which may be associated with gastritis. A complete blood count (CBC) can check for anemia due to bleeding, while other blood tests may measure vitamin levels, especially if autoimmune gastritis or vitamin B-12 deficiency is suspected.

5. Urea breath test
   

   A urea breath test is a non-invasive test used to detect H. pylori infection, one of the main causes of gastritis. The patient ingests a urea solution, and if H. pylori is present, it will break down the urea, releasing carbon dioxide, which can then be measured in the breath sample.

6. Imaging tests
   

   In some cases, imaging tests like X-rays or CT scans may be ordered to rule out other digestive issues that could cause similar symptoms, such as ulcers or structural abnormalities. These tests are often done with a contrast material (like barium) to improve visibility in the digestive tract.

7. Biopsy analysis
   

   If a biopsy is taken during endoscopy, it can be analyzed to check for H. pylori bacteria, cancer cells, or other abnormalities in the stomach lining. This detailed examination helps confirm the presence of infection or chronic inflammation.

8. Tests for autoimmune markers
   

   If autoimmune gastritis is suspected, blood tests may be done to detect antibodies against intrinsic factor or stomach cells, which can indicate an autoimmune response damaging the stomach lining.

These diagnostic procedures help doctors accurately determine the cause and severity of gastritis, allowing for an effective treatment plan. Early and precise diagnosis is essential for managing symptoms and preventing potential complications.

Complications of Untreated Gastritis

If gastritis is left untreated, especially if chronic or severe, it can lead to several serious health complications. Timely diagnosis and treatment are essential to avoid these potential outcomes. Here are some complications associated with untreated gastritis:

1. Stomach ulcers
   

   Persistent inflammation weakens the stomach lining, which can lead to the formation of open sores, or ulcers. These ulcers may cause significant pain and are vulnerable to bleeding. Ulcers resulting from untreated gastritis can also become infected, leading to further complications.

2. Gastrointestinal bleeding
   

   Chronic gastritis can cause the stomach lining to erode and bleed, which may lead to noticeable symptoms like vomiting blood or passing dark, tarry stools. Prolonged bleeding can cause anemia and may require medical intervention to stop the bleeding and prevent further blood loss.

3. Increased risk of stomach cancer
   

   Long-term gastritis, particularly from Helicobacter pylori infection or autoimmune gastritis, is associated with an increased risk of developing gastric (stomach) cancer. Chronic inflammation changes the stomach lining over time, creating an environment where cancer cells can more easily develop.

4. Vitamin B-12 deficiency and anemia
   

   Autoimmune gastritis or chronic gastritis can interfere with the stomach’s ability to absorb essential nutrients, particularly vitamin B-12. This deficiency can lead to pernicious anemia, a condition where the body lacks sufficient healthy red blood cells, causing fatigue, weakness, and neurological symptoms if left untreated.

5. Perforation of the stomach lining
   

   Severe ulcers or erosion from prolonged gastritis can lead to perforation, where a hole forms in the stomach wall. This is a medical emergency, as it allows stomach contents to leak into the abdominal cavity, potentially causing a life-threatening infection known as peritonitis.

6. Increased risk of other digestive disorders
   

   Untreated gastritis may predispose individuals to other gastrointestinal disorders, such as peptic ulcer disease and gastroesophageal reflux disease (GERD). These conditions can cause additional digestive complications and discomfort, impacting the quality of life.

7. Reduced quality of life
   

   Chronic, untreated gastritis can lead to constant pain, nausea, and discomfort, impacting a person’s ability to eat, sleep, and enjoy daily activities. Over time, this can lead to weight loss, malnutrition, and mental health issues due to ongoing discomfort.

Untreated gastritis has the potential to cause both immediate and long-term health complications. Seeking medical advice and appropriate treatment can help manage symptoms, heal the stomach lining, and reduce the risk of these serious health issues.

Causes of Gastritis

Gastritis is directly caused by factors that inflame or damage the stomach lining, leading to irritation and reduced protection against stomach acid. These are the primary direct causes:

1. Helicobacter pylori (H. pylori) infection. This bacterium directly infects and inflames the stomach lining. H. pylori infection disrupts the stomach’s protective layer, increasing vulnerability to stomach acid, which can lead to chronic gastritis and raise the risk of ulcers and, over time, stomach cancer.
2. Bile reflux. This condition occurs when bile—a digestive fluid produced by the liver—flows backward from the bile ducts into the stomach. Bile is highly irritating to the stomach lining, and its presence in the stomach can directly inflame and damage the protective mucosal layer, leading to gastritis.
3. Excessive alcohol consumption. Alcohol is a corrosive substance that can directly erode the stomach’s mucosal lining, making it weaker and more susceptible to acid damage. Over time, this erosion can lead to persistent inflammation of the stomach lining, resulting in gastritis.
4. Frequent use of NSAIDs and certain medications. Nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen and aspirin can interfere with the stomach’s natural defense mechanisms by reducing protective mucus production. This allows stomach acid to come into contact with the stomach lining, leading to irritation and inflammation.
5. Persistent vomiting. Repeated vomiting brings stomach acid into constant contact with the stomach lining, which weakens and inflames it. This direct exposure to acid can cause acute gastritis and, if ongoing, lead to chronic inflammation.
6. Infections beyond H. pylori. Certain other bacteria and viruses, such as Salmonella or Cytomegalovirus (CMV), can infect the stomach lining directly, causing inflammation and, in some cases, severe gastritis.

Addressing these direct causes is crucial for managing gastritis effectively and preventing complications like ulcers, chronic inflammation, or, in severe cases, stomach cancer.

Prevention of Gastritis

Gastritis is relatively easy to prevent by avoiding common triggers that irritate the stomach lining. Key irritants to avoid include aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs), excessive alcohol, coffee, and smoking. It is also best to steer clear of carbonated beverages, such as soft drinks, and drinks high in citric acid, which can contribute to stomach acidity and irritation.

Here are additional steps that can help effectively prevent gastritis:

1. Eat smaller, more frequent meals. Consuming small meals more frequently rather than large meals at once can reduce stress on the stomach, helping prevent acid buildup and irritation.
2. Engage in regular exercise. Physical activity supports digestive health and helps reduce the likelihood of digestive issues, including gastritis.
3. Maintain a healthy weight. Keeping a balanced weight can lower the risk of acid reflux, which can contribute to gastritis if left unchecked.
4. Manage stress effectively. Stress has been linked to increased stomach acid production, which can aggravate or trigger gastritis. Techniques like mindfulness, relaxation exercises, and adequate sleep can help keep stress in check.

By adopting these lifestyle habits, one can significantly lower the risk of gastritis and maintain overall digestive health.

Risk Factors for Gastritis

Anyone can develop gastritis, especially under the following conditions:

1. Age. Older adults are at a higher risk of gastritis because the stomach lining tends to thin with age, making it more susceptible to irritation. Additionally, older adults are more exposed to H. pylori infections and autoimmune conditions that can lead to gastritis.
2. Excessive alcohol consumption. Drinking large amounts of alcohol weakens the stomach lining, making it more vulnerable to damage from stomach acid. Excessive alcohol consumption increases the likelihood of gastritis and other acid-related stomach conditions.
3. High levels of stress. Acute stress has been shown to trigger gastritis. This is because the body releases higher levels of gastric acid during times of stress, which can irritate the stomach lining and lead to inflammation.
4. Frequent or regular use of painkillers. Common pain relievers, such as ibuprofen, aspirin, and naproxen, can lead to recurrent gastritis if used continuously. These medications reduce the stomach’s protective lining, making it more susceptible to inflammation and irritation.
5. Susceptibility to bacterial infection. Helicobacter pylori infection is common worldwide, but not everyone with this bacterium develops gastritis. People who are more susceptible to H. pylori infections—often due to genetic factors—are at higher risk of gastritis and may have a family history of the condition.
6. Autoimmune gastritis. In this condition, the body’s immune system mistakenly attacks the cells in the stomach lining. Autoimmune gastritis often occurs alongside vitamin B-12 deficiency, as this deficiency can further weaken the stomach lining.

Additionally, individuals with HIV/AIDS, parasitic infections, or inflammatory conditions such as Crohn’s disease are also at increased risk for developing gastritis. Understanding these risk factors can help identify those who may benefit from preventative measures or early medical attention to manage symptoms.
