The most important facts at a glance
Chronic atrophic gastritis in dogs is a long-term inflammation of the gastric mucosa, which leads to its regression. This mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients. protects the stomach and produces important digestive substances. Causes of the inflammation can be infections, autoimmune reactions, or certain medications. A common cause is infectionAn infection is the colonization and multiplication of pathogens such as bacteria, viruses, fungi, or parasites in an organism, which often, but not always, leads to a disease. with Helicobacter bacteriaBacteria are microscopic, single-celled organisms that exist in almost every environment on Earth. Some types of bacteria are beneficial or even essential to life, while others can cause disease.. Parasites or autoimmune diseasesAutoimmune diseases are conditions in which the immune system mistakenly attacks the body's own cells or tissues as if they were foreign substances. Examples in dogs and cats include autoimmune hemolytic anemia and systemic lupus erythematosus., in which the immune systemThe immune system is the body's defense system against infectious agents such as bacteria, viruses, fungi, and parasites. It comprises a complex network of organs, cells, and molecules that work together to protect the body. attacks its own cells, can also play a role. Symptoms include Vomiting, AbdominalThe term "abdominal" refers to anything that concerns the belly or the abdomen. It is an adjectival expression used to describe the location, symptoms, or conditions that occur in the abdominal area. pain, loss of appetite, and Weight loss. The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. is made by a clinical examination, blood tests, imaging procedures such as ultrasoundUltrasound refers to sound waves that are above the hearing threshold of the human ear. In medicine, ultrasound is used for diagnostic imaging procedures to visualize internal organs, tissues, and blood flow., and an endoscopyEndoscopy is a diagnostic procedure that uses an endoscope (a thin, flexible tube with a light source and a camera at the end) to examine and visualize the inside of the body, often for diagnostic or therapeutic purposes., in which tissue samples are taken.
The treatment aims to reduce inflammatory conditions and alleviate symptoms. A dietary change to easily digestible food is recommended. Medications can reduce gastric acid production and protect the gastric mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients.. Antibiotics are used for bacterial infections, while immunosuppressants may be necessary for autoimmune causes. The prognosisThe prognosis is the prediction of the likely course and outcome of a disease based on the general state of health, the nature of the disease, and the response to treatment. It can provide information on how a disease is expected to develop. depends on the cause and severity, but with timely diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests.

A complete cure is not always possible, and lifelong treatment may be required.
Preventive measures are difficult, but a balanced diet and regular veterinary check-ups can help reduce the risk. Avoiding known triggers and monitoring risk factors, such as bacterial infections, are also important to minimize the occurrence of the disease.
Causes
The stomach of dogs is lined with a mucous membrane that forms a protective layer and is responsible for the production of gastric acid and digestive enzymesEnzymes are biological catalysts that accelerate specific chemical reactions in the body without being consumed. They play a crucial role in virtually all physiological processes.. This mucosaMucosa, also called mucous membrane, refers to the moist lining of body cavities that are connected to the outside world, such as the mouth, nose, lungs, and gastrointestinal tract. It serves to protect and facilitate the absorption of nutrients. consists of cells that are kept intact by constant cell renewal and a protective layer of mucus.
