Gastritis is a condition where the lining of the stomach becomes inflamed or irritated. It can develop suddenly (acute gastritis) or persist over time (chronic gastritis). Many people experience gastritis at some point in their lives, but when left untreated, it can lead to serious complications like ulcers or stomach bleeding.
Common symptoms of gastritis include stomach pain, bloating, nausea, vomiting, and indigestion. The condition can be caused by infections, excessive alcohol consumption, prolonged use of painkillers, or stress. Understanding the causes, symptoms, and treatment options can help in managing and preventing gastritis effectively.

What Is Gastritis?
Gastritis refers to inflammation of the stomach lining due to damage from stomach acids, infections, or irritants. The stomach lining produces mucus to protect itself from acidic digestive juices. When this protective barrier is weakened, the acid can irritate the stomach walls, leading to gastritis.
The condition may be mild or severe, and symptoms can vary from person to person. In some cases, gastritis may go unnoticed, while in others, it can cause significant discomfort and complications.

Signs and Symptoms of Gastritis
Symptoms of gastritis can be mild or severe, depending on the cause and severity of inflammation. Some people may not experience symptoms at all.
Common Symptoms of Gastritis:
- Burning or gnawing pain in the stomach (especially between meals or at night).
- Indigestion (dyspepsia) – bloating, burping, or feeling too full after eating.
- Nausea and vomiting – in some cases, vomiting blood (hematemesis) may occur.
- Loss of appetite and unintentional weight loss.
- Black or tarry stools – a sign of stomach bleeding.
- Acid reflux or heartburn (burning sensation in the chest).
If gastritis is severe or untreated, it can lead to stomach ulcers, which may cause more intense pain and bleeding.

What Causes Gastritis?
Gastritis can have several causes, ranging from infections to lifestyle factors. The most common causes include:
Helicobacter Pylori (H. Pylori) Infection
A common bacterial infection that weakens the stomach lining, allowing acid to cause irritation and ulcers. It spreads through contaminated food, water, or close contact.
Excessive Use of NSAIDs (Painkillers)
Frequent use of NSAIDs can damage the stomach lining, increasing the risk of gastritis.
Alcohol Consumption
Heavy alcohol intake irritates the stomach lining and increases acid production, leading to inflammation.
Stress and Anxiety
Severe stress, trauma, or surgery can trigger gastritis by boosting stomach acid production.
Autoimmune Gastritis
The immune system mistakenly attacks the stomach lining, causing chronic inflammation. It is linked to pernicious anemia and vitamin B12 deficiency.
Other Causes
- Bile reflux (bile flowing back into the stomach from the liver).
- Smoking, which increases stomach acid and slows healing.
- Certain infections (viral, fungal, or parasitic infections).

Types of Gastritis
Gastritis can be classified into different types based on its cause and duration.
- Acute Gastritis – This type occurs suddenly due to factors like NSAIDs, alcohol, or infections. Symptoms are intense but short-lived and usually improve with proper treatment.
- Chronic Gastritis – Long-term inflammation of the stomach lining, often caused by H. pylori infection, autoimmune disorders, or irritants like smoking and alcohol. If untreated, it can lead to ulcers and increase the risk of stomach cancer.
- Erosive Gastritis – A severe form where the stomach lining wears away, leading to ulcers and bleeding. It is commonly associated with prolonged NSAID use, alcohol abuse, or extreme stress.
- Non-Erosive Gastritis – This type involves inflammation without significant damage to the stomach lining. It is often linked to H. pylori infection or autoimmune diseases and may not cause noticeable symptoms initially.
- Autoimmune Gastritis – The immune system mistakenly attacks stomach cells, causing chronic inflammation and vitamin B12 deficiency. This condition can lead to anemia and long-term digestive issues if not managed properly.
How Is Gastritis Diagnosed?
Doctors diagnose gastritis through a combination of tests and evaluations. They begin with a medical history and physical exam, discussing symptoms, diet, and medication use. If needed, an endoscopy is performed, where a thin tube with a camera is inserted into the stomach to check for inflammation or ulcers. To detect H. pylori infection, doctors may recommend a breath, stool, or blood test. A stool test can also be used to check for hidden blood, which may indicate stomach bleeding. In some cases, a biopsy is taken from the stomach lining and examined under a microscope to confirm the diagnosis.
Treatment for Gastritis
Treatment depends on the underlying cause but usually includes medications and lifestyle changes.
Medications for Gastritis help reduce stomach acid, relieve pain, and protect the stomach lining. Some drugs neutralize acid, while others lower its production or aid in healing stomach inflammation.
Dietary and Lifestyle Changes can prevent flare-ups. Eating small, frequent meals and avoiding spicy, fried, and acidic foods reduces irritation. Limiting alcohol, caffeine, and smoking helps protect the stomach lining, while stress management promotes healing.
Home Remedies for Gastritis Relief include ginger tea to reduce inflammation, aloe vera juice to soothe the stomach, and probiotics to support digestion. Turmeric milk also helps with its anti-inflammatory properties.
Complications of Untreated Gastritis include stomach ulcers, internal bleeding, anemia, and vitamin deficiencies. Long-term cases may increase the risk of stomach cancer, making early treatment essential.
Conclusion
Gastritis is a common digestive condition that causes stomach pain, discomfort, and potential health risks if untreated. It can result from H. pylori infection, excessive NSAID use, alcohol, stress, or autoimmune disorders. Managing gastritis involves identifying and avoiding triggers, taking medications to reduce acid or treat infections, and maintaining a healthy diet and lifestyle. If you experience persistent stomach pain, nausea, vomiting, or black stools, consult a doctor for proper diagnosis and treatment. Early management can prevent complications and support a healthy digestive system.
