Gastritis is a common medical condition characterised by the inflammation of the stomach lining. The stomach produces acid to help digest food and has a protective mucus barrier to prevent this acid from damaging the stomach wall. When this barrier becomes weakened or damaged, the stomach lining can become inflamed, leading to various digestive symptoms. Gastritis can occur suddenly as an acute episode or develop slowly over time as a chronic condition. In the United Kingdom, it is a frequently managed gastric issue that can often be resolved with appropriate lifestyle adjustments and medical treatment once the underlying cause is identified by a healthcare professional.

Gastritis is the inflammation of the protective lining of the stomach
The condition occurs when the mucosal barrier that protects the stomach wall is compromised, allowing digestive juices to damage and inflame the tissue. Gastritis is a common condition where the stomach lining becomes inflamed often resulting from an infection or the regular use of certain pain relief medications. This inflammation can lead to a variety of uncomfortable sensations in the upper abdomen. While many cases are mild and resolve quickly with treatment, persistent inflammation requires clinical investigation to prevent potential complications such as stomach ulcers or nutritional Lack.
Identifying common symptoms and sensations
The symptoms of gastritis can vary between individuals, but most people experience a dull ache or burning sensation in the upper part of the tummy. Heartburn and acid reflux are common symptoms of gastritis alongside a feeling of fullness after eating only a small amount. Other frequent signs include persistent indigestion, feeling sick or being sick, and a loss of appetite. In some cases, the inflammation can be asymptomatic, meaning a person may not realise they have the condition until it is identified during a routine medical examination for other digestive issues.
Primary causes: bacteria, medications, and lifestyle
The most frequent cause of chronic gastritis is an infection with Helicobacter pylori (H. pylori) bacteria, which colonise the stomach lining and weaken its protective barrier. Another major cause is the long-term or frequent use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or aspirin, which can irritate the stomach wall. According to the National Institute for Health and Care Excellence, clinicians should assess for H. pylori infection in patients with persistent gastric symptoms as part of a standard diagnostic pathway. Lifestyle factors, including excessive alcohol consumption and high levels of physiological stress, can also contribute to the erosion of the stomach lining and subsequent inflammation.
Diagnostic pathways and medical treatments
To confirm a diagnosis of gastritis, UK doctors may use various tests, including a breath or stool test to check for H. pylori or a blood test to screen for anaemia. In some persistent cases, a gastroscopy may be performed, where a thin, flexible camera is used to look directly at the stomach lining. Treatment for gastritis usually involves taking antacids and other medicines to reduce stomach acid, which allows the inflammation to heal. Common medications include proton pump inhibitors (PPIs) and H2 blockers. If an H. pylori infection is found, a course of antibiotics will be prescribed alongside acid suppressants to clear the bacteria and prevent the condition from returning.
Conclusion
Gastritis is a manageable condition involving the inflammation of the stomach lining, often caused by bacterial infection or specific medications. While it can cause significant discomfort and indigestion, most cases respond well to acid-suppressing treatments and lifestyle changes. Identifying the specific cause is essential for ensuring the correct treatment plan is followed to promote full healing of the stomach wall. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Is gastritis the same as an ulcer?
No, gastritis is general inflammation of the lining, whereas an ulcer is a specific open sore that has formed on the stomach wall.
Can stress cause gastritis?
While emotional stress is not the primary cause, severe physiological stress from major illness or injury can lead to acute gastric inflammation.
How long does it take for gastritis to heal?
With proper treatment and by avoiding triggers, acute gastritis often improves within a few days or weeks.
Can I drink alcohol if I have gastritis?
Alcohol can further irritate the stomach lining, so it is generally advised to avoid or significantly reduce intake during recovery.
Are there specific foods I should avoid?
Many people find that spicy, acidic, or very fatty foods worsen their symptoms, though individual triggers can vary.
Is gastritis contagious?
The inflammation itself is not contagious, but the H. pylori bacteria that often cause it can be passed between people through close contact.
Can gastritis cause weight loss?
Yes, persistent nausea and a loss of appetite can lead to unintentional weight loss if the condition is not managed.
