The term “Gastritis” refers to a collection of diseases that all have one thing in common: inflammation of the stomach lining. Infection with the same bacteria that causes most stomach ulcers is the most common cause of gastritis.

Gastritis can strike quickly (acute) or gradually (chronic) (chronic). Gastritis can cause ulcers and raise the risk of stomach cancer in some people. Gastritis, on the other hand, is usually not severe and responds to therapy rapidly.

Gastritis is now classified based on its duration (acute vs chronic), histological characteristics, anatomic distribution, and underlying pathogenic processes. If untreated, acute gastritis will progress to chronic gastritis. The most prevalent cause of gastritis is Helicobacter pylori (H. pylori).

Gastritis was detected in 60 to 70% of H. pylori-negative patients with functional dyspepsia or non-erosive gastroesophageal reflux. The a etiology, epidemiology, pathophysiology, histology, assessment, differential diagnosis, and treatment of gastritis are covered in this exercise.


  • Determine the cause of gastritis.
  • Describe how to diagnose gastritis using clinical methods.
  • Examine contemporary gastritis therapy and management options.
  • Emphasize the significance of professional team teamwork and communication in improving the delivery of treatment for patients with gastritis, resulting in positive patient outcomes.

What is the Definition of Gastritis?

Gastritis is a frequent disease in which the stomach lining becomes irritated. It can be bothersome, and it should be addressed to prevent the problem from becoming chronic (long term).

If your gastritis is moderate, simple lifestyle modifications and over-the-counter medication may be all you need to manage it.

However, if it is severe, chronic, or not properly managed, it might lead to other issues.

Gastritis is a category of illnesses that affect the stomach lining, causing inflammation. Acute gastritis develops quickly and often responds to treatment, but chronic gastritis takes time to develop.

A bacteria called H. pylori is most commonly responsible for stomach lining irritation. From moderate gastritis to severe gastritis, there’s a wide range of symptoms. The severity of the disease may not necessarily be linked to the symptoms.

Acute Gastritis: What Is It?

Acute gastritis is a disease in which the gastric mucosa, or stomach lining, becomes irritated abruptly.

A gastroenterologist’s endoscopy indicates a reddish lining in the specimens, as well as a significant number of acute inflammatory cells (mainly white blood cells, called leucocytes).

Acute erosions (“erosive gastritis”), small, shallow breaches in the surface lining, and even microscopic bleeding patches are possible.

What is the Definition of Chronic Gastritis?

Chronic gastritis is a long-term condition characterised by low-grade inflammation and damage to the stomach lining. The mucosa of the stomach thins as normal cells in the mucosa die.

Lymphocytes are among the inflammatory cells, suggesting that an immune response has occurred.

This is quite prevalent, particularly in developing nations. Because mucosal changes have been present for a long period, they can progress to a stage known as metaplasia, which is linked to a slightly increased risk of gastric cancer..

What is the Prevalence of Gastritis?

Acute (sudden) gastritis affects around 8 individuals out of every 1,000. Gastritis that lasts a long time is less prevalent. It affects around 2 people out of every 10,000.


Gastritis can be brought on by the following factors:

  • Consumption of hot meals
  • Long-term usage of nonsteroidal anti-inflammatory medications (NSAIDs) (NSAIDs)
  • Bacterial infection, such as Helicobacter pylori (H. pylori)
  • a major operation
  • Burns or traumatic injuries
  • Infection that is severe
  • Physiologically extreme stress
  • Megaloblastic (pernicious) anaemia and autoimmune illnesses, for example.

It can be caused by a variety of dietary and lifestyle factors, including:

  • Consumption of hot meals
  • Smoking
  • Excessive anxiety
  • Prolonged use of aspirin and other over-the-counter pain relievers and fever reducers.

Gastritis can be caused by a variety of health problems, including:

  • Bacterial and viral infections are the most common types of infections.
  • A major operation
  • Burns or traumatic injuries

Gastritis can be caused by a variety of illnesses. These are some of them:

  • Autoimmune diseases are a kind of autoimmune disease. When your immune system mistakenly assaults your body’s healthy cells.
  • Reflux of bile on a regular basis. When bile, a digestive fluid, backs up into your stomach and food tract, it causes indigestion (esophagus).
  • Anemia caused by pernicious anaemia. When your stomach is unable to absorb vitamin B12, you get anaemia.


What kinds of gastritis are there? There are two kinds of gastroenteritis:

  1. Erosive gastritis
  2. Non – Erosive

Erosive (reactive) Gastritis is characterised by inflammation as well as erosion (wearing away) of the stomach lining. Reactive gastritis is another term for this disease. Smoking, NSAIDs, corticosteroids, viral or bacterial infections, and stress from diseases or traumas are some of the causes.

Non-Erosive: Stomach lining inflammation without erosion or compromise.


The following tests are used to diagnose gastritis:


A thin, flexible tube is inserted down the oesophagus and into the stomach. The endoscope has a tiny camera attached to it that allows the doctor to examine the stomach lining. This might suggest gastritis if the mucosa of the stomach is reddish. For confirmation, a biopsy is required.


during an endoscopy, tiny tissue samples are extracted and analysed in the lab. The pathologist will search for inflammatory cells and damage to the epithelium, among other things.


Gastritis can be treated in a variety of 4 ways, including:

1. Identifying the cause

Determining the source of the problem – once the source has been determined, actions may be taken to avoid exposure. If aqua vitae bottle is causing inflammation, for example, you can abstain or limit the quantity of aqua vitae bottle you consume. Anti-inflammatory medications used to treat other problems may need to be discontinued or replaced with something else.

2. Medication

pills are available to help lower the amount of acid in the stomach fluids. Depending on your condition, you may need to take these drugs for a few weeks or months.

3. Dietary Modifications

Changes of Dietary, such as reducing or eliminating aqua vitae bottle and caffeine, both of which irritate the stomach lining.

4. There Is No Therapy

gastritis is frequently discovered by accident during an endoscopy. There is typically no need to treat the gastritis if Helicobacter pylori is not present and no additional abnormalities on biopsy are visible.
