Question: What are the symptoms of gastritis and gastropathy?
Answer: The majority of people with gastritis or gastropathy don’t have any symptoms.

In some cases, gastritis and gastropathy cause symptoms of indigestion, also called dyspepsia. Symptoms may include

pain or discomfort in the upperabdomen
nauseaorvomiting
feeling full too soon during a meal
feeling too full after a meal
loss of appetite
weight loss

If gastritis or gastropathy leads to erosions or ulcers, the stomach lining may bleed. If you have symptoms of bleeding in your stomach, seek medical help right away. Symptoms of bleeding in your stomach may include

black or tarrystoolor red or maroon blood mixed with your stool
cramps, discomfort, or pain in your abdomen
feeling tired, short of breath, or light-headed
red blood invomitor vomit that looks like coffee grounds

If you have mild bleeding in your stomach, you may have a small amount of blood in your stool and not notice it. This is called occult bleeding.
Question: What causes gastritis and gastropathy?
Answer: Different types of gastritis and gastropathy have different causes.

Common causes of gastritis and gastropathy

Helicobacter pylori (H. pylori) gastritis. Infection with H. pylori bacteria causes H. pylori gastritis. Researchers are still studying how people become infected. H. pylori bacteria may spread from person to person through contact with an infected person’s vomit, stool, or saliva. Food or water contaminated with an infected person’s vomit, stool, or saliva may also spread the bacteria from person to person.

Reactive gastropathy. Reactive gastropathy is caused by long-term contact with substances that irritate the stomach lining, most often nonsteroidal anti-inflammatory drugs (NSAIDs), alcohol, and bile reflux, which is backward flow of bile from the small intestine to the stomach. Surgery that removes part of the stomach—such as some types of weight-loss surgery, also called metabolic and bariatric surgery—is the most common cause of bile reflux.

Autoimmune gastritis. In autoimmune gastritis, the immune system attacks healthy cells in the stomach lining.

Acute erosive gastropathy. Serious health problems—such as severe injuries or burns, critical illness, or sepsis—can reduce the blood flow to the stomach lining, causing a form of acute erosive gastropathy called stress gastritis.

Contact with substances that irritate the stomach lining—including NSAIDs, alcohol, and cocaine—can also cause acute erosive gastropathy.

Other causes of gastritis and gastropathy

Less common causes of gastritis and gastropathy include

celiac disease
chemotherapyandradiation therapy
diseases that cause inflammation in the digestive tract, such asCrohn's diseaseandsarcoidosis
food allergies
infections withviruses,parasites,fungi, and bacteria other thanH. pylori, typically in people with weakened immune systems
