Question: What are the symptoms of Autoimmune atrophic gastritis ?
Answer: What are the signs and symptoms of autoimmune atrophic gastritis? In some cases, autoimmune atrophic gastritis does not cause any obvious signs and symptoms. However, some people may experience nausea, vomiting, a feeling of fullness in the upper abdomen after eating, or abdominal pain. It is often associated with impaired absorption of vitamin B12 and possibly other vitamin deficiencies (such as folate and iron). People with vitamin B12 deficiency are at risk for pernicious anemia, a condition in which the body does not have enough healthy red blood cells. Autoimmune atrophic gastritis is considered a "precancerous" condition and it may be responsible for the development of gastric adenocarcinoma or carcinoids.
