Which are the causes of Gastritis?

Causes of Gastritis

Gastritis is a condition characterized by inflammation of the stomach lining. It can be acute, with sudden onset and short duration, or chronic, lasting for a longer period of time. Gastritis can be caused by various factors, including:

Infection:

Helicobacter pylori (H. pylori) infection: This bacterium is one of the most common causes of gastritis. It is estimated that over half of the world's population is infected with H. pylori. The bacteria can weaken the protective lining of the stomach, leading to inflammation and gastritis. H. pylori is usually contracted through contaminated food or water, and it can also be transmitted from person to person.

Regular use of certain medications:

Nonsteroidal anti-inflammatory drugs (NSAIDs): Commonly used pain relievers like aspirin, ibuprofen, and naproxen can irritate the stomach lining and cause gastritis. Prolonged or excessive use of these medications can increase the risk of developing gastritis.

Corticosteroids: These medications, often prescribed for various inflammatory conditions, can also contribute to the development of gastritis when used for an extended period.

Excessive alcohol consumption:

Alcohol: Heavy and prolonged alcohol consumption can irritate and erode the stomach lining, leading to gastritis. Alcohol can also increase the production of stomach acid, further exacerbating the condition.

Stress and autoimmune disorders:

Stress: Prolonged stress can weaken the immune system and disrupt the normal functioning of the digestive system, making the stomach more susceptible to inflammation and gastritis.

Autoimmune disorders: In some cases, the immune system mistakenly attacks the cells of the stomach lining, leading to chronic gastritis. Conditions such as autoimmune gastritis and pernicious anemia fall into this category.

Other causes:

Bile reflux: When bile, a digestive fluid produced by the liver, flows back into the stomach, it can cause irritation and inflammation of the stomach lining, resulting in gastritis.

Smoking: Smoking weakens the stomach's protective lining and impairs its ability to heal, making it more susceptible to gastritis.

Age: The risk of developing gastritis increases with age, as the stomach lining naturally thins and becomes more vulnerable to inflammation.

Other medical conditions: Certain medical conditions, such as Crohn's disease, HIV/AIDS, and kidney failure, can increase the risk of gastritis.

It is important to note that the causes of gastritis can vary from person to person, and sometimes multiple factors may contribute to its development. If you experience symptoms of gastritis, such as abdominal pain, nausea, vomiting, or indigestion, it is advisable to consult a healthcare professional for an accurate diagnosis and appropriate treatment.
