I am 46 years old diagnosed 6 years ago with autoimmune pernicious anemia by virtue of symptoms, low serum B12 (was 85) plus anti-intrinsic factor antibody being positive. I am negative for H Pylori.
I had my first endoscopy last week and the gastroenterologist told me my stomach had no evidence at all of any stomach atrophy which greatly surprised him as typically a person with my profile has atrophy.
He wants to do further tests looking at my blood fasting gastrin levels, and for anti-parietal cell antibodies and perhaps another endoscopy looking at acid stomach secretions. This is due to an increased risk of carcinoids if there is no stomach acid or I have achlorohydria.
Has anyone had an endoscopy with similar results? What does this all mean? Thought the stomach atrophy is the cause of low B12? I am very confused.
