Pernicious anemia is considered to be an autoimmune disease, in which the
body's own immune system mistakenly damages its own tissues. It is believed that
the decreased absorption of vitamin B-12 from the gastrointestinal tract in
pernicious anemia results from the presence of an autoantibody against intrinsic
factor (IF), a protein made in the stomach that is necessary for the absorption
of vitamin B-12. Normally, vitamin B-12 binds to intrinsic factor in the
stomach, and this facilitates its absorption by the small intestine further
along in the digestive process. Along with the autoimmune process that attacks
the IF protein and lowers IF levels in stomach secretions, another autoimmune
reaction against the stomach lining cells also occurs, resulting in a form of
inflammation known as chronic atrophic gastritis.
Is pernicious anemia the same as vitamin B-12 deficiency anemia?
Pernicious anemia is one form of vitamin B-12 deficiency that results from
the autoimmune process described above. However, other causes of vitamin B-12
deficiency can also produce the same signs and symptoms as pernicious anemia.
Other potential causes of vitamin B-12 deficiency include surgical removal of
the stomach or a portion of the stomach (total or partial gastrectomy), other
gastrointestinal diseases such as celiac disease or
Crohn's disease, infections
of the gastrointestinal tract, and poor nutrition.
Pernicious Anemia - Symptoms At Onset Of DiseaseQuestion: The symptoms of pernicious anemia can vary greatly from patient to patient. What were your symptoms at the onset of your disease?
Anemia is the condition of having less than the normal number of red blood cells or less than the normal quantity of hemoglobin in the blood. The oxygen-carrying capacity of the blood is, therefore, decreased.
Though the cause of stomach cancer is unknown, risk factors for stomach cancer include diet, H. pylori infection, smoking age, gastritis, stomach surgery, family history, and pernicious anemia. Symptoms include stomach discomfort, feeling full after a small meal, nausea and vomiting, and weight loss. Treatment depends upon staging and may involve surgery, radiation therapy, or chemotherapy.
Dementia is a significant loss of intellectual abilities such as memory capacity, severe enough to interfere with social or occupational functioning. There are different criteria classification schemes for dementias such as cortical, subcortical, progressive, primary, and secondary dementias. Other conditions and medication reactions can also cause dementia. Dementia is diagnosed based on a certain set of criteria. Treatment for dementia is generally focused on the symptoms of the disease.
Vitiligo is a condition in which the skin turns white due to the loss of pigment from the melanocytes, cells that produce the pigment melanin that gives the skin color.
Thrombocytopenia refers to a decreased number of platelets in the blood. There are many causes of thrombocytopenia such as decreased platelet production (viral infections for example rubella, mumps, chickenpox, hepatitis C, and HIV); increased platelet destruction or consumption (for example sulfonamide antibiotics, heparin, blood transfusions, and lupus); or increased splenic sequestration (enlarged spleen due to conditions for example liver disease, blood cancers, and more). Treatment of thrombocytopenia depends on the cause.
Gastritis is an inflammation of the stomach lining. Causes of gastritis include drinking too much alcohol, medications such as NSAIDs, ibuprofen, aspirin, H. pylori infection, severe infections, burns, anemia, and autoimmune disorders. Gastritis is diagnosed with endoscopy, blood tests, or stool tests. Treatment depends upon the cause of gastritis.
Birthmarks and other abnormal skin pigmentation is caused by the body's inability to produce enough melanin. Abnormal skin pigmentation can cause conditions such as vitiligo, pigmentation loss, melasma, albinism, port wine stains, macular stains and hemangioma.
Graves' disease is an autoimmune disease that affects the thyroid. Some of the symptoms of Graves' disease include hand tremors, rapid heartbeat, trouble sleeping, enlarged thyroid, thinning of the skin or fine brittle hair. Causes of Graves' disease are thought to be multifactorial such as genes, gender, stress, and infection. Treatment for Graves' disease is generally medication.
Iron is a mineral our bodies need. Iron deficiency is a condition resulting from not enough iron in the body. It is the most common nutritional deficiency and the leading cause in the US. Iron deficiency is caused due to increased iron deficiency from diseases, nutritional deficiency, or blood loss and the body's inability to intake or absorb iron. Children, teen girls, pregnant women, and babies are at most risk for developing iron deficiency. Symptoms of iron deficiency include feeling weak and tired, decreased work or school performance, slow social development, difficulty maintaining body temperature, decreased immune function, and an inflamed tongue. Blood tests can confirm an iron deficiency in an individual. Treatment depends on the cause of the deficiency. Proper diet that includes recommended daily allowances of iron may prevent some cases of iron deficiency.
Enjoying a healthy diet helps to prevent diseases. A good diet also helps to control celiac disease, diabetes, and high blood pressure and maintain health by preventing loss of bone mass, muscle strength, and vitamin deficiencies.
Stiff-Person syndrome is a neurological disorder associated with features of an autoimmune disease. Signs and symptoms of Stiff-Person syndrome include a heightened sensitivity to stimuli (noise, touch, emotional distress) and fluctuating muscle rigidity of the trunk and limbs. Conditions associated with Stiff-Person syndrome include thyroiditis, vitiligo, pernicious anemia, and diabetes. Treatment for Stiff-Person syndrome is generally medication to control symptoms.
