Learn about gastritis

Gastritis is a condition that leads to stomach lining inflammation, causing stomach pain, bloating, and nausea. It has a variety of causes and can come on suddenly (acute) or gradually (chronic). Fortunately, medications and lifestyle changes can reduce stomach acid and ease uncomfortable symptoms.

There are 7 types of gastritis:

Acute gastritis: Acute gastritis can include serious complications, such as hemorrhages. The most common cause of acute gastritis is the overuse of nonsteroidal anti-inflammatory drugs (NSAIDs).
Chronic gastritis: Chronic gastritis includes long-term or repeated inflammation of the stomach lining. It can lead to upper abdominal pain, bloating, and loss of appetite.
Atrophic gastritis: Atrophic gastritis, known as type A or B gastritis, is a type of chronic gastritis. Chronic atrophic gastritis interferes with stomach functioning, killing the cells needed to properly digest food.
Antral gastritis: Antral gastritis affects the lower portion of the stomach. It can be caused by a virus, bacterial infection, stomach injury, or certain medications, with the most common symptom being indigestion.
Autoimmune gastritis: Autoimmune atrophic gastritis is a chronic inflammatory disease. The body's immune system mistakes stomach cells as harmful, disrupting the production of gastric acid.
Erosive gastritis: Erosive gastritis causes ulcers and bleeding in the protective lining of the stomach. While it's typically acute, it can also be chronic. Some patients show little to no symptoms, while others experience severe abdominal pain.
Alcoholic gastritis: Alcoholic gastritis is caused by the consumption of excessive alcohol. Alcohol limits the stomach's ability to produce acids, which leads to inflammation.

Gastritis causes

Gastritis occurs when something damages or weakens the stomach lining. There are a number of possible causes of gastritis, including:

Alcohol abuse

Chronic excessive alcohol use can irritate and erode the protective lining of the stomach.

Autoimmune disorders

In some people, the body's immune system attacks healthy cells in the stomach lining, causing gastritis.

Bacterial infection

Helicobacter pylori bacteria are the main cause of chronic gastritis and peptic ulcer disease (stomach ulcers). H. pylori infection damages the stomach lining.

Bile reflux

The liver produces bile to digest fatty foods. Bile reflux occurs when bile flows back into the stomach instead of progressing through the small intestine.

Medications

The overuse of nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or aspirin, or other anti-inflammatories like corticosteroids can weaken the stomach lining.

Physical stress

A sudden illness or injury can cause gastritis. Sometimes, gastritis develops after physical injuries that don't affect the stomach.

Gastritis symptoms

Many people with gastritis do not experience symptoms, and those with symptoms often mistake them for indigestion. Some common symptoms of gastritis include:

Loss of appetite
Nausea, vomiting, or bloating
Feeling extra full after a meal
Stomach ulcers
Diarrhea
Upper abdominal pain and cramps
Blood in your stool
Fever

Because gastritis weakens the stomach lining, it can lead to bleeding. If you notice any signs of bleeding, including vomiting blood, black stools, or blood in your tool, seek medical attention immediately by calling 911

How to diagnose & treat gastritis

How to diagnose gastritis

Sometimes, usually when gastritis is mild, symptoms and history may be enough for your doctor to form a probable diagnosis that can be treated based on suspicion that gastritis is the cause. Most often, however, a combination of laboratory testing, imaging, physical exam, and viewing the stomach with a camera (endoscopy) may be necessary to form a proper diagnosis. Plushcare doctors will help guide patients to appropriate in-person and specialist care if any of those are needed. Doctors who specialize in the stomach and digestive tract are called gastroenterologists. The treatment of gastritis will depend on the underlying cause. If your healthcare provider does not find an underlying cause, they may recommend treatments to reduce symptoms.

How to treat gastritis

After gastritis is diagnosed, it is important to limit your consumption of irritating substances, such as spicy foods, alcohol, and NSAIDs. If you have an upset stomach, book an appointment with a doctor to discuss your treatment options.

Gastritis medication

Depending on the cause of your gastritis, your health care provider may recommend the following medications:

Antibiotics

Antibiotics can help treat bacterial infections, including Pylori infections. Depending on the infection, you may need to take more than one type of antibiotic.

Antacids

Calcium carbonate medications help reduce stomach acid exposure and relieve inflammation.

Antihistamine H2 Blockers

H2 blockers, such as Pepcid (famotidine), help reduce acid production by limiting the function of H2 antihistamine receptors in the stomach which, in part, are responsible for stomach acidity.

Proton pump inhibitors (PPIs)

Proton pump inhibitors, such as Omeprazole (Prilosec), Lansoprazole (Prevacid), Rabeprazole (Aciphex), and Pantoprazole (Protonix), can help reduce the amount of acid your stomach produces.

Nexium (Esomeprazole) Protonix (Pantoprazole)

How to prevent gastritis

H. pylori bacteria are easily transmitted, but it is possible to reduce your risk of infection by practicing good hygiene.

In addition, you can take steps to minimize indigestion. Some effective preventive measures include:

Avoiding fatty, fried, spicy, or acidic foods
Reducing your caffeine consumption
Eating smaller meals throughout the day
Finding healthy ways to cope with stress
Not taking NSAIDs including Motrin or Advil (ibuprofen), Aleve (naproxen), or Aspirin
Lowering your alcohol consumption
Not lying down for 2–3 hours after eating

Related conditions to gastritis

Abdominal pain and discomfort

There are several potential causes of abdominal pain and discomfort, including gastritis. In most cases, abdominal pain related to gastritis includes a gnawing or burning pain (indigestion) in the middle-upper abdomen.

Stomach flu

Viral gastroenteritis (stomach flu) involves diarrhea, generalized abdominal cramps, nausea, vomiting, and fever.

Stomach ulcers

An ulcer is a patch of inflamed stomach lining. Ulcers cause more localized and severe pain, along with an increased risk of stomach cancer, bleeding, and perforation.

Diarrhea

Gastritis typically involves nausea and vomiting, while the stomach flu often leads to diarrhea.

Crohn's disease

Crohn's disease is a type of inflammatory bowel disease (IBD) that leads to inflammation of the lower digestive tract, sometimes leading to bloody diarrhea and lower abdominal cramps.

Gastritis treatment FAQs

What is the best treatment for gastritis?

The best treatment will depend on the underlying cause of your gastritis. In most cases, treatment for gastritis includes a combination of lifestyle changes, antibiotics to fight H. Pylori infection, and proton pump inhibitors to reduce stomach acid production.

What is the best medicine for gastritis?

For immediate relief from gastritis, antacids can help neutralize stomach acid.

If your gastritis is caused by an infection, your health care provider may prescribe antibiotics to fight Pylori bacteria. In addition, your doctor may recommend proton pump inhibitors to reduce stomach acid.

How long does gastritis take to heal?

Acute gastritis can last anywhere from 2 to 10 days. Meanwhile, chronic (long-term) gastritis can last for weeks or months depending on the underlying cause.

What triggers gastritis?

Gastritis is commonly caused by H. pylori infection. It can also be triggered by excessive alcohol use, physical stress, the overuse of NSAIDs, and the consumption of irritating foods.

Can gastritis go away on its own?

Yes, gastritis can go away on its own, and many people recover from gastritis without medical intervention. However, medication can help speed up the healing process.

What are the possible complications of gastritis?

Without proper treatment, gastritis can lead to serious health conditions, including acute blood loss anemia, infectious complications like peritonitis and sepsis, stomach cancer, and even death. It is crucial to call 911 and seek medical attention immediately if you have any severe symptoms.

Can gastritis be prevented?

It's possible to reduce your risk of H. Pylori infection by practicing good hygiene, including hand washing. In addition, healthy lifestyle changes, such as reducing stress, reducing alcohol consumption and avoiding irritating foods, can lower your risk of gastritis.
