Does atrophic gastritis cause iron deficiency?
Core tip: Chronic atrophic autoimmune gastritis is an autoimmune disease characterized by progressive parietal cells destruction leading to hypochlorhydria and intrinsic factor deficiency. These alterations may result in vitamin B12 deficiency and iron malabsorption.
How does gastric atrophy cause anemia?
As a result, the stomach’s secretion of essential substances such as hydrochloric acid, pepsin, and intrinsic factor is impaired, leading to digestive problems. The most common are vitamin B12 deficiency which results in a megaloblastic anemia and malabsorption of iron, leading to iron deficiency anaemia.
How does H pylori cause iron deficiency?
H. pylori infection is associated with anemia by impairing iron absorption as a result of chronic gastritis which causes gastric hypochlorhydria, leading to impair reduction of the dietary iron from the ferric to ferrous form [13, 14].
What is atrophic gastric mucosa?
Gastric mucosal atrophy is defined as the loss of appropriate glands, which occurs when glands damaged by inflammation are replaced either by connective tissue (scarring) or by glandular structures inappropriate for location (metaplasia).
Is atrophic gastritis and autoimmune disease?
Autoimmune atrophic gastritis is considered an autoimmune disorder. In people who are affected by this condition, the immune system mistakenly attacks the healthy cells of the stomach lining.
How does gastritis affect iron absorption?
Autoimmune gastritis is a chronic inflammatory disease with destruction of parietal cells of the corpus and fundus of the stomach. The known consequence is vitamin B12 deficiency and, consequently, pernicious anemia.
Does gastritis prevent iron absorption?
Autoimmune atrophic gastritis Iron absorption is severely impaired in achylia gastrica43 as normal gastric secretion and acidity are essential for solubilizing and reducing dietary iron.
Is atrophic gastritis the same as autoimmune gastritis?
pylori-related gastritis will develop atrophic gastritis. Otherwise, atrophic gastritis can be an inherited or genetic condition, which is called autoimmune atrophic gastritis. Here, the immune system attacks the healthy cells in the stomach lining.
What parasite causes iron deficiency?
SUMMARY. The main parasites causing blood loss in man and leading to direct iron-deficiency anemia are the common worm infections. These include hookworm infection (Necator americanus and Ancylostoma duodenale); whipworm infection (Trichuris trichiura); and schistosomiasis (Schistosoma mansoni, S. haematobium, and S.
Does H. pylori affect iron levels?
Helicobacter pylori (H. pylori) infection impairs iron uptake (6) and a number of studies have found an association between H. pylori infection and low serum ferritin levels or iron deficiency (7–10).
Can Vitamin B12 deficiency cause gastritis?
Atrophic gastritis was more common in individuals with B12 deficiency, while superficial gastritis was the most common finding in controls. The incidence of intestinal metaplasia (in the antrum) was similar in the individuals with or without B12 deficiency.
Which effect of atrophic gastritis can result in vitamin B12 deficiency?
Autoimmune chronic atrophic gastritis is a rare etiology of vitamin B12 deficiency, which results in a destruction of the parietal cells, leading to a reduction in intrinsic factor, which is essential to the absorption of vitamin B12.
How to treat anemia due to iron deficiency?
Treatment Planning for Dental procedures in Anemic Patients: From Dental point of view only the symptoms can be controlled like using antiseptic gels for the ulcers and mouth washes but for the signs and symptoms to completely subside the cause of the Iron deficiency should be fixed by taking help of a physician.
Are there oral signs and symptoms of iron deficiency?
Oral Signs and Symptoms of Anemia due to Iron Deficiency. Anemia caused due to Iron Deficiency which is caused due to blood loss has many Oral signs and symptoms and it is important to a dentist to identify these and act accordingly. Iron deficiency Anemia is the most common type of anemia which affects approximately 30% of the world’s population.
How is low gastric acid related to Iron malabsorption?
The possible role of achlorhydria in the development of iron malabsorption has been suggested in different hypo/ achlorhydria models.16 Low gastric acid secretion results from parietal cell loss. This low gastric acid production leads to decreased food iron solubilization and decreased iron absorption.
How does atrophic gastritis lead to nutritional deficiencies?
Atrophic gastritis, regardless of its cause, leads to nutritional deficiencies through parietal cell atrophy and the resulting achlorhydria. Vitamin B12 deficiency is well described, but often diagnosed late.
