What is Antral Gastritis and Why Gut Experts Treat it Differently
Antral gastritis refers to a common medical condition where the inner stomach lining of the stomach’s antral region becomes red and swollen. It is a relatively common stomach condition affecting people of different ages. At SRM Global Hospitals, we focus on identifying the root causes of antral gastritis to provide the most effective antral gastritis treatment.
What is the Stomach Antral Region?
The stomach’s antral region, often called the gastric antrum, is the lower, funnel-shaped part of your stomach, which connects the central part of the stomach (the body) to the small intestine.
While the upper parts of the stomach store food, the stomach’s antral region acts as a heavy-duty mixer. The antral region has thick muscular walls that perform a process called peristalsis (muscles contract rhythmically to grind food into a semi-liquid paste). The food paste is necessary for the digestion process to work correctly in the small intestine.
Why is Antral Gastritis Common?
The antrum often gets accumulated by food and bacteria like H. pylori, as it is a meeting point for the stomach and small intestine. The C-shape of the stomach with favoured gravity makes this region a frequent target for bacterial infection.
Bile reflux from the small intestine also reaches the antrum first, exposing the stomach lining to irritants like H. pylori bacteria and digestive juices. Frequent contact with these irritants makes the stomach lining in the antrum prone to chronic inflammation and gastritis.
Untreated antral gastritis can result in complications such as anaemia from bleeding ulcers. Chronic inflammation may increase the risk of stomach cancer.
Potential Complications of Antral Gastritis
If left untreated, chronic inflammation can lead to:
- Stomach ulcers or stomach lining erosion
- Gastrointestinal bleeding
- Pernicious anaemia from impaired vitamin B12 absorption
- Gastric cancer
Recent data shows that over 70% of new stomach cancer cases occur in the Asia Pacific region, with the antrum being the most common site.
Risk Factors for Complications:
- Untreated bacterial infections
- Chronic alcohol consumption
- Severe bile reflux
- Autoimmune disorders
Antral Gastritis Symptoms
Antral gastritis effects can range from mild to severe, which depends on the cause and duration. In mild cases, symptoms may be limited to occasional bloating, burping, or a slight burning sensation in the upper stomach. However, when the condition becomes severe or prolonged, patients may experience intense upper abdominal pain, persistent nausea, vomiting, loss of appetite, and even dark or tarry stools.
| Symptom / Feeling | What Happens in the Stomach | Why It Matters / When to Seek Help |
|---|---|---|
| Burning or munching sensation | Upper stomach feels like burning or munching, worse on an empty stomach | Persistent or worsening pain could signal ulcer formation or severe inflammation |
| Upper abdominal pain & discomfort | General digestive discomfort, heaviness, or pressure | May indicate worsening inflammation |
| Bloating & early fullness | The stomach feels full and distended after small meals due to delayed gastric emptying. | Severe bloating can affect appetite and nutrition |
| Nausea & occasional vomiting | Vomiting may be mild or severe; in extreme cases, vomit may contain blood or resemble coffee grounds. | Immediate medical attention is needed if vomiting blood occurs |
| Acid reflux / sour taste | Stomach acid flows back into the oesophagus, causing burning in the chest or mouth. | Frequent reflux can irritate the oesophagus and worsen gastritis |
| Loss of appetite | Constant discomfort reduces the desire to eat, possibly leading to weight loss. | Persistent appetite loss may cause malnutrition |
| Frequent burping | Excess gas and irregular digestion due to an inflamed stomach lining | Could indicate worsening gastritis or other digestive issues |
| Dark or tarry stools | May indicate gastrointestinal bleeding | Requires immediate medical care to prevent anaemia |
| Anaemia due to bleeding ulcers | Chronic inflammation or bleeding ulcers reduce red blood cell levels | Can cause fatigue, weakness, and pale skin |
| Vitamin B12 deficiency / Pernicious anaemia | Autoimmune gastritis impairs B12 absorption, affecting red blood cell production. | Vitamin B12 supplementation or injections may be needed to prevent severe deficiency. |
| Dietary triggers | Spicy, acidic, high-fat foods and alcohol can worsen symptoms | Avoiding triggers supports healing and reduces discomfort |
Causes of Antral Gastritis
| Cause / Trigger | How It Affects the Stomach | Risk Factors |
|---|---|---|
| Helicobacter pylori infection | Bacteria colonise the stomach lining, causing chronic inflammation | In India, ~54% of people with digestive issues are affected (2024–2025 research). A major contributor to ulcer and gastritis progression. |
| Bile reflux | Digestive fluid from the liver flows back into the stomach, irritating the lining and triggering inflammation. | Can worsen existing gastritis and increase risk of ulcers; often linked to gallbladder surgery or motility issues. |
| Medicines / Pain killers – Nonsteroidal Anti-Inflammatory Drugs (NSAIDs) | Long-term use can erode the protective stomach lining, making it more susceptible to acid damage. | Includes pain relievers like ibuprofen or aspirin; risk increases with prolonged or high-dose use. |
| Alcohol consumption | Chronic intake irritates and inflames the stomach wall, weakening protective mucosa. | Heavy drinking delays healing, increases acid production, and can aggravate bleeding ulcers. |
| Autoimmune disorders | The immune system attacks healthy stomach cells, reducing acid regulation and impairing vitamin B12 absorption. | It can lead to pernicious anaemia and chronic inflammation over time. |
| Dietary & lifestyle factors | Spicy foods, acidic foods, high-fat meals, smoking, and alcohol irritate the stomach lining and increase acid production. | Trigger foods can worsen burning, bloating, and nausea; smoking slows healing; frequent consumption of alcohol may increase ulcer risk and prolong symptom duration. |
How We Diagnose Antral Gastritis
Diagnosing antral gastritis involves identifying the cause, severity, and potential complications along with an advanced treatment plan of SRM Global Hospital.
- Blood Tests: They detect the presence of H. pylori infection and check for nutritional deficiencies, such as low vitamin B12, which can result from autoimmune gastritis or chronic inflammation. Blood tests also evaluate for anaemia caused by bleeding ulcers.
- Breath or Stool Tests: They are non-invasive diagnoses specifically designed to detect H. pylori infection, the most common cause of antral gastritis.
- Upper Endoscopy: Considered the higher standard for minimally invasive diagnosis, endoscopy involves inserting a small camera through the mouth to examine the stomach lining directly. It allows doctors to visually assess the extent of inflammation, redness, or ulceration.
- According to the ICMR medical guidelines, simply seeing redness in the stomach lining is not enough for a definitive diagnosis. Pathologists often take a biopsy (small tissue sample) during endoscopy to examine it under a microscope to detect:
- Early signs of gastric cancer
- Gastrointestinal bleeding or erosions
- Chronic inflammation that may require long-term management
Antral Gastritis Treatment and Management
Medications
| Treatment | Purpose | Benefits |

FAQs on Antral Gastritis
1. What is antral gastritis, and how does it differ between the acute and chronic types?
Antral gastritis is the inflammation in the lower part of the stomach (antrum), caused by viruses or bacteria, triggers such as excessive alcohol consumption, or bile reflux. The acute type develops suddenly, while the chronic type progresses slowly over time.
2. What are the common symptoms of antral gastritis that people usually feel?
People often feel discomfort after food intake. The antral gastritis has the typical symptoms as burning or aching sensation in the upper abdomen, bloating, nausea, loss of appetite, frequent burping, and acid reflux caused by corrosive stomach acid.
3. How is antral gastritis diagnosed through endoscopy?
Endoscopy is a minimally invasive procedure that allows doctors to examine the stomach mucosa directly for inflammation. Accurate diagnosis helps determine whether mild antral gastritis or advanced disease is present, guides the treatment of antral gastritis safely and prevents serious complications like peptic ulcers.
4. How is antral gastritis treated, and can symptoms be reduced?
Antral gastritis treated effectively depends on the underlying cause. Antibiotics are prescribed for H. pylori infection. Medicines for antral gastritis neutralise stomach acid and help reduce irritation of the stomach lining. Low-acid fruits like bananas, apples, and pears support digestion. Stress management techniques, including relaxation exercises, help manage symptoms and alleviate discomfort.
5. When should symptoms of antral gastritis be taken seriously?
If symptoms last longer than a week, worsen over time immediate medical attention. The warning signs, like blood vomiting, black stools, sudden weight loss, or signs of vitamin B12 deficiencies, may indicate internal bleeding or other serious complications.
