Atrophic gastritis is a condition that affects nearly 8% of the population.It is a form of chronicgastritisthat changes the cells in the stomach lining, wherestomach acidis made. It can cause several symptoms, such as stomach pain and tiredness, but it may also present without any symptoms.

Definition of Atrophic Gastritis

Gastritis is the inflammation of the stomach lining. Atrophic gastritis is a form of chronic gastritis that also has the following features:

Location

Atrophic gastritis affects the lining of the stomach, medically known as the gastric mucosa. This layer of the stomach contains the cells that makestomach acidand protects the stomach against irritation.

Bacterial Infection vs. Autoimmune

There are two common causes of atrophic gastritis: abacterial infectionand anautoimmuneresponse.

H. pyloriis spread through contact with infected saliva, stool, or vomit. It can also be spread through contaminated water and food.

Autoimmune atrophic gastritis occurs when the body attacks the healthy cells in the stomach lining. This leads to decreased stomach acid production and the loss of intrinsic factor, a protein that helps the body absorb vitamin B12.

Those with autoimmune atrophic gastritis can have significant vitamin B12 deficiency anemia, which is called pernicious anemia.

Acute vs. Chronic vs. Atrophic Gastritis

Gastritisis the inflammation of the stomach lining.

Atrophic gastritisis when chronic gastritis also involves cell changes in the stomach lining causing atrophy and a decrease in stomach acid production.

How Does Stomach Inflammation Happen?

Stomach inflammation refers to the swelling and irritation of the lining of the stomach. It can happen from anH. pyloriinfection, autoimmune response,bile reflux, or lifestyle factors. Lifestyle factors can include:

Your Guide to Living With Gastritis

Risk Factors

One of the main risk factors for atrophic gastritis is anH. pyloriinfection. According to the Centers for Disease Control and Prevention (CDC), certain populations have a higher likelihood of acquiringH. pylori. These populations include:

Autoimmune atrophic gastritis was formerly thought to be a disease mainly affecting older women of northern European ancestry. However, it has been found in people of all ages, ethnicities, and genders.

Prevention

There is no perfect way to prevent gastritis. However, there are ways to reduce your risk of developing the condition, including:

People with atrophic gastritis may not have symptoms until late into their disease. This makes it difficult to diagnose and treat promptly.

Autoimmune atrophic gastritis symptoms are generally a result of thevitamin B12 deficiencycalledpernicious anemia. These symptoms can include:

Diagnostic Testing

Blood tests may be used to look at gastric function, but the gold standard diagnostic test is an upper endoscopy, also known as anesophagogastroduodenoscopy(EGD).

An EGD is a small scope inserted into the mouth, advanced through theesophagus, and passed into the stomach. With a small camera on the end, it can take images of the stomach and also remove tissue for biopsies. An EGD can confirm the gastritis diagnosis.

If a healthcare provider suspects anH. pyloriinfection, they may order a blood, stool, or breath test to diagnose the infection.

Atrophic gastritis treatment is focused on managing the underlying cause of the condition.

Since the majority of people with atrophic gastritis have anH. pyloriinfection, it is important to treat and eliminate that bacterium.H. pyloritreatment involves taking aproton pump inhibitor (PPI)and two antibiotics for the prescribed length of time.

If the patient has vitamin B12 deficiency,supplements, or intravenous (IV) infusions may be used to restore their levels.

An affected gastric mucosa can return to normal in some people who successfully have theirH. pyloriinfection treated.

Atrophic gastritis is considered a precursor to stomach cancer. However, most people who have atrophic gastritis will not get stomach cancer.

A 2017 study showed less than 2% of people with atrophic gastritis gotstomach cancer.

While there is a link between atrophic gastritis and cancer, it is not guaranteed. It’s important to look at other risk factors, likealcohol consumptionand age, which may play a factor in the development of stomach cancer.

Management After Initial Treatment

Immediate management of atrophic gastritis involvesantibiotics(as appropriate) and PPI medications. The American Gastroenterological Association (AGA) recommends a routineEGDto look for stomach cancer and other stomach changes. The AGA recommends performing an EGD every three years in people with advanced atrophic gastritis.

Frequently Asked QuestionsOne of the causes of atrophic gastritis is anH. pyloriinfection. AfterH. pyloriis treated, it may be possible to be reinfected with the bacteria.Atrophic gastritis is always a precancerous condition. However, less than 2% of people with atrophic gastritis will develop cancer.There is no natural way to treat atrophic gastritis, but there are lifestyle changes that can help. Removing irritants from the diet can reduce stomach irritation. Avoiding smoking, stress, and NSAIDs can also help relieve symptoms.
