Pernicious anemia is an autoimmune disease that primarily affects the absorption of vitamin B12 in the stomach. While pernicious anemia itself is not directly associated with other autoimmune diseases, individuals with autoimmune conditions may have an increased risk of developing multiple autoimmune diseases simultaneously.
Some autoimmune diseases that individuals with pernicious anemia might be at a higher risk of developing as part of APS or due to shared autoimmune mechanisms include:
Autoimmune Thyroid Diseases:
These include conditions like Hashimoto's thyroiditis and Graves' disease.
Type 1 Diabetes:
An autoimmune form of diabetes.
Addison's Disease:
An autoimmune condition affecting the adrenal glands.
Vitiligo:
An autoimmune disorder causing depigmentation of the skin.
Celiac Disease:
An autoimmune disorder triggered by the ingestion of gluten.
Rheumatoid Arthritis:
An autoimmune disease that primarily affects the joints.
