Antral Gastritis: Causes, Best Treatments, and Symptoms Explained
Antral gastritis is a condition marked by inflammation in the antrum, the lower part of the stomach. This area plays a vital role in regulating stomach acid production and digestion. When irritated, the stomach lining can become red, swollen, or eroded, causing discomfort and leading to more serious issues if untreated.
While it can be mild and manageable, persistent inflammation increases the risk of ulcers and, in rare cases, developing gastric cancer. Recognising the symptoms and causes early helps in prompt diagnosis and treatment. With the right care, antral gastritis can be managed effectively to prevent further complications.
What Is Antral Gastritis?
Antral gastritis refers to inflammation or irritation of the stomach’s antral region. The antrum helps control stomach acid release into the intestines. When inflamed, this part of the stomach lining may develop swelling, redness, or even erosion.
It can be classified as acute or chronic and may progress into erosive antral gastritis, where the inner stomach lining starts wearing away.The condition may be mild or severe, depending on its cause and duration.
Mild antral gastritis often causes subtle symptoms but may still require treatment, as it can worsen if left untreated . Left untreated, it can worsen, leading to ulcers, bleeding, or long-term damage to the stomach wall.
Common Causes of Antral Gastritis
Antral gastritis can develop due to various irritants and bacterial infections that inflame or damage the stomach lining. From infections to lifestyle habits, identifying the root cause is essential for appropriate antral gastritis treatment. Below are some of the primary causes.
1. Helicobacter pylori (H. pylori) Infection
One of the most common causes is H. pylori infection. This bacterium lives in the stomach lining and can weaken the protective mucus layer. Over time, it increases stomach acid contact with the tissue, causing inflammation.
Chronic H. pylori infection may lead to mild antral gastritis, erosive antral gastritis, or peptic ulcers. H. pylori is contagious and is often contracted in childhood.
If untreated, it increases the risk of stomach ulcers and, in some cases, gastric cancer. Blood tests or breath tests are used to detect this infection, which can be treated with antibiotics and acid-reducing medications.
2. Long-Term Use of NSAIDs
Regular use of nonsteroidal anti-inflammatory drugs like aspirin, ibuprofen, or naproxen can damage the stomach lining. These medications reduce the production of protective prostaglandins, which help shield the stomach from corrosive stomach acid.
Without this protection, the risk of developing erosive gastritis or gastrointestinal bleeding increases. People taking NSAIDs for chronic pain, arthritis, or cardiovascular conditions may unknowingly irritate their stomach lining over time.
Antral gastritis caused by NSAIDs often requires reducing or stopping the medication, switching to alternatives, or adding medications to protect the stomach, such as proton pump inhibitors.
3. Autoimmune Diseases
Autoimmune gastritis occurs when the immune system mistakenly attacks healthy stomach lining cells. This response causes chronic inflammation and can affect stomach acid production. While autoimmune gastritis more often impacts the body of the stomach, it may also involve the antrum.
People with autoimmune disorders like Type 1 diabetes, Hashimoto’s thyroiditis, or Addison’s disease may be at increased risk. Over time, this damage can interfere with digestion and nutrient absorption, especially vitamin B12.
Diagnosis often requires blood tests to check for specific antibodies and vitamin deficiencies. Early detection helps in managing symptoms and preventing complications.
4. Alcohol and Smoking
Alcohol can irritate the stomach mucosa directly, especially when consumed in excess. It increases stomach acid production, damages the inner stomach lining, and weakens its defenses. Smoking compounds the issue by reducing blood flow to the stomach lining, impairing healing, and encouraging H. pylori growth.
Together, these habits significantly raise the risk of both acute gastritis and chronic inflammation. Regular alcohol intake and smoking not only irritate the stomach but also delay recovery during treatment.
Reducing or eliminating these habits and maintaining a healthy diet is key to managing antral gastritis and reducing long-term risk factors like peptic ulcers and stomach cancer.
5. Bile Reflux
Bile reflux occurs when bile flows backward from the small intestine into the stomach. Unlike acid reflux, which involves the esophagus, bile reflux affects the stomach directly. Bile is a digestive fluid that, when mixed with stomach acid, can damage the antral mucosa.
This condition is often seen after gallbladder surgery or in people with poor gastrointestinal motility.Chronic exposure leads to inflammation, stomach lining erosion, and potentially erosive antral gastritis.
Symptoms mimic acid reflux but do not respond well to acid-reducing drugs alone. Management may include dietary changes, bile acid binders, or surgical procedures if severe.
Symptoms of Antral Gastritis
The symptoms of antral gastritis vary depending on its severity and duration. Some people may not notice any issues, while others may experience ongoing stomach discomfort. The inflammation caused by antral gastritis disrupts digestion and increases sensitivity to stomach acid.
Upper Abdomen Pain
A burning or gnawing sensation in the upper abdomen is common, especially after meals or on an empty stomach.
Bloating and Gas
Swelling or tightness in the stomach area often occurs due to excess stomach acid or food not digesting properly.
Nausea and Vomiting
Feeling nauseated is frequent. In severe cases, vomiting blood or material resembling coffee grounds may occur.
Loss of Appetite
Due to constant discomfort, many people eat less, which may lead to weight loss and fatigue.
Frequent Burping or Acid Reflux
Stomach acid flowing back into the esophagus can cause heartburn and persistent burping, especially after eating.
When to Seek Medical Help
Seek medical help if symptoms last longer than a week, worsen over time, or include vomiting blood, black stools, or unexplained weight loss. Persistent upper abdomen pain, loss of appetite, and signs of gastrointestinal bleeding require immediate attention.
Early diagnosis prevents serious complications like stomach ulcers or stomach cancer.People with autoimmune diseases, chronic NSAID use, or H. pylori infection should monitor symptoms closely.
Regular check-ups help manage antral gastritis and track response to treatment. Ignoring these signs may lead to long-term damage to the stomach wall.
How Antral Gastritis Is Diagnosed
Doctors use several methods to diagnose antral gastritis and determine the cause.
| Diagnostic Test | Description |
|---|---|
| Endoscopy | A thin tube with a camera examines the stomach lining for inflammation. |
| Biopsy | A small tissue sample is taken during endoscopy to check for H. pylori. |
| Blood Tests | These check for anemia, H. pylori antibodies, or vitamin B12 deficiency. |
| Urea Breath Test | Detects H. pylori infection through breath analysis after drinking a liquid. |
| Stool Antigen Test | Identifies H. pylori proteins in stool samples. |
Early diagnosis helps in creating a tailored treatment plan and reducing antral gastritis symptoms.
Best Treatments for Antral Gastritis
Treatment for antral gastritis depends on its cause and severity, often aiming to reduce stomach acid production . The goal is to reduce inflammation, alleviate symptoms, and prevent further damage to the stomach lining.
Proton Pump Inhibitors (PPIs):
These reduce stomach acid production, easing irritation and allowing the stomach lining to heal.
Antibiotics for H. pylori:
A course of antibiotics is prescribed if Helicobacter pylori infection is detected.
Antacids:
Used to neutralise stomach acid and provide quick relief from burning sensations.
Stopping NSAIDs:
Patients are advised to discontinue or replace NSAIDs with less harmful alternatives.
Dietary Changes:
Avoiding acidic foods, spicy meals, and alcohol helps reduce antral gastritis symptoms and promote healing while preventing flare-ups.
Preventing Flare-ups and Managing Long-Term Gastritis
Preventing gastritis recurrence involves consistent care and healthy choices. People with a history of antral gastritis should focus on protecting the stomach lining and avoiding known irritants.
Tips to prevent and manage long-term gastritis:
- Eat small, frequent meals
- Avoid NSAIDs or use them under medical advice
- Limit spicy, acidic, and fried foods
- Quit smoking and alcohol
- Manage stress levels
- Take prescribed medications regularly
- Follow up with regular health check-ups
These habits reduce antral gastritis symptoms and promote long-term healing.
