Acute Gastritis: Causes, Symptoms & Treatment

What is Acute Gastritis?

Acute gastritis is nothing but an inflammation or swelling occurring in the stomach lining. Of course, it is caused by several reasons and lifestyle changes. It can cause severe and nagging pain, and it feels uncomfortable sometimes. But don’t worry; the pain is temporary and usually occurs for only a few hours. 

Those who have acute gastritis may experience inflammation or swelling. It may happen as quickly as possible, and harrowing moments are caused. The condition may occur due to bacteria, foods, or medications. 

Acute Gastritis vs Chronic Gastritis

Gastritis is the inflammation of the stomach lining. Acute gastritis means it happens suddenly. It is severe and lasts a short time. Chronic gastritis, as the name suggests, is long-lasting. It develops slowly over time and inflammation increases the longer it is left untreated. Those with chronic gastritis may also have more sensitive triggers and experience flare-ups.

Can Stress Cause Acute Gastritis?

When the body is under intense physical or emotional stress, it triggers changes in the stomach acid levels and reduces blood flow to the stomach lining. This weakens the lining’s natural defenses and makes it more prone to irritation. Stress-related acute gastritis is especially common after major surgery, serious illness, or severe injury. Even long-term emotional stress from work or personal life can play a role. Managing stress through regular exercise, proper sleep, and relaxation techniques can go a long way in keeping your stomach healthy.
