Gastritis is an inflammation of the stomach lining. When it develops suddenly, it is acute gastritis. It can occur for many reasons, including bacterial infections and autoimmune diseases.
Acute gastritis can cause abdominal pain, vomiting, and weight loss. In more serious cases, it
This article provides a detailed overview of acute gastritis.
However, this condition can sometimes cause:
- upper abdominal pain or discomfort
- feeling full too quickly, during or after a meal
- appetite loss
- weight loss
Sometimes, gastritis can lead to erosion and ulcers, causing the stomach to bleed. This is serious and may cause:
- black or tarry stool
- red or maroon blood mixed in the stool
- abdominal cramps, discomfort, or pain
- shortness of breath
- red blood in vomit
- vomit that has the appearance of ground coffee
Anyone with symptoms of stomach bleeding should seek medical assistance immediately.
There are many possible causes of gastritis. A 2023 paper lists these as follows:
- stomach infections
- use of nonsteroidal anti-inflammatory drugs (NSAIDs)
- alcohol consumption
- excessive stomach acid production
- autoimmune conditions affecting the stomach
The most common causes of gastritis are alcohol consumption, use of NSAIDs, and infections from the Helicobacter pylori bacteria.
There are several risk factors for acute gastritis. These are things that indicate an increased risk of acute gastritis, although they might not actually cause this condition.
According to a 2023 review, gastritis from an autoimmune disease is
Scientists also believe that previous stomach surgery is a gastritis risk factor.
There are several principal tests for diagnosing acute gastritis. The National Health Service (NHS) in the United Kingdom lists these as follows:
- a breath test, which can detect H. pylori in the breath of individuals after consuming a special drink
- laboratory tests on a sample of stool
- laboratory tests on a blood sample
These tests help to determine the underlying cause of gastritis. Having this information is necessary for effective treatment.
- For infectious gastritis: Antibiotics to treat the underlying infection.
- For gastritis that arises from excess stomach acid: Medication to manage stomach acid such as antacids, proton pump inhibitors, and alginates.
- For gastritis due to alcohol: Stopping alcohol consumption.
- For gastritis that arises from NSAIDs: Stopping the use of NSAIDs and taking different medications.
If these treatments do not work, an individual may need further testing.
The outlook for people with gastritis can depend on its underlying cause.
According to a 2019 study, the same is true of autoimmune gastritis. However, individuals with autoimmune gastritis also tend to receive an earlier gastric cancer diagnosis. This can improve the efficacy of gastric cancer treatment.
Gastritis is an inflammation of the stomach lining, which is acute when occurring suddenly.
Most people with gastritis do not experience symptoms. However, some people may have indigestion-like symptoms. These include upper abdominal pain, vomiting, and weight loss.
Gastritis can also lead to erosion and ulcers, resulting in gastric bleeding. This can lead to bloody stool, bloody vomit, and shortness of breath. It requires immediate medical attention.
The principal tests for diagnosing acute gastritis include a breath test to detect H. pylori. They also include laboratory tests on stool and blood samples.
This allows for effective treatment, which may involve antibiotics, not drinking alcohol, or changes in medication.
