Gastritis is made up of two words- gastro, meaning stomach, and itis, which means inflammation. In this condition, the protective lining of the stomach becomes inflamed. This condition can be acute and occur suddenly in severe form. In chronic form, gastritis can exist for years if not treated. Erosive gastritis is less common but serious and can lead to bleeding and ulcers. The formation of ulcers and cancer of the stomach can occur if this condition is not treated on time. It is important to know the causes of gastritis to understand the condition better.


How is Gastritis Caused?

Gastritis can occur if the protective lining of the stomach becomes weak or damaged. It can be categorized as erosive or non-erosive. In erosive gastritis, erosion of the stomach lining and the formation of ulcers occur, while in non-erosive gastritis, irritation or reddening of the stomach lining occurs. Given below are the main causes of gastritis as well as the causative factors that increase the risk of gastritis.

  • Infection with Helicobacter pylori (H. Pylori): H. pylori bacteria is the causative agent for infectious gastritis. This bacteria grows in the mucous lining of the stomach and causes inflammation. H. pylori infection can spread through food, water, and contact with infected people.
  • Excessive alcohol consumption: Chronic consumption of alcohol can irritate and inflame the stomach lining. Alcohol consumption can also increase the secretion of stomach acid, which can further harm the stomach lining.
  • Use of pain relievers like non-steroid anti-inflammatory drugs (NSAIDs): NSAIDs can increase the permeability of the gastric membranes, neutrophil infiltration, and production of oxygen-free radicals, which can increase the risk of gastritis.
  • Autoimmune disorders: Chronic inflammation can also result from autoimmune disease, where immune cells start attacking their own cells.
  • Stress: Acute gastritis can result from major surgical procedures, injury, severe infections, or burns.
  • Ageing: In older adults, the stomach lining becomes thin, which increases the risk of gastritis. Apart from a thinner lining, the chances of H. pylori infection and autoimmune disorders are high in older adults.
  • Cancer treatment: chemotherapy or radiotherapy to treat cancer can also make the stomach lining thinner and more vulnerable to ulcers.
  • Other causes of gastritis include viral infections, fungal infections, tobacco use, digestive disorders like Crohn’s disease, bile reflux, and reduced blood supply.

Gastritis is a serious health condition that needs medical intervention. Infection, excessive consumption of alcohol, stress, autoimmune diseases, cancer therapy, and the use of NSAIDs are some of the causative factors for gastritis. Autoimmune disorders, stress, ageing, cancer treatments, and various infections can also weaken the stomach lining. Awareness of the causes of gastritis is essential for prevention and timely treatment to avoid complications like ulcers and cancer. Also, ensure that you have a health insurance plan in place to safeguard yourself against any financial stress.
