Pernicious anemia involves autoimmune inflammation in the stomach and the inability to absorb vitamin B12 in the small intestine. While vitamin B12 deficiency anemia may be caused by a lack of vitamin B12 in the diet, pernicious anemia is caused by an inability to absorb vitamin B12.
Severe or long-lasting pernicious anemia can damage the heart, brain, and other organs in the body. Pernicious anemia also can cause other problems, such as nerve damage, neurological problems (such as memory loss), and digestive tract problems.
Anemia is a condition in which the body does not have enough healthy red blood cells. Red blood cells provide oxygen to body tissues. There are many types of anemia. Pernicious anemia is a decrease in red blood cells that occurs when the intestines cannot properly absorb vitamin B12.
Currently, early recognition and treatment of pernicious anemia provide a normal, and usually uncomplicated, lifespan. Delayed treatment permits progression of the anemia and neurologic complications. If patients are not treated early in the disease, neurological complications can become permanent.
Individuals with pernicious anemia were also at significantly increased risk of developing myeloma (OR: 1.55), acute myeloid leukemia (OR: 1.68) and myelodysplastic syndromes (OR: 2.87).
The Social Security Administration (SSA) has a listing specifically for pernicious anemia. In order to qualify under this listing, you must show that you have: Been diagnosed with pernicious anemia. Been impaired in at least two of your extremities because of the condition.
Pernicious anemia is a chronic disease that progresses slowly and steadily. In the past, before much was known about the disease and there was no treatment, it would eventually cause death after many years of suffering.
You cannot give blood if you have Pernicious Anaemia. You cannot give blood if you are taking prescribed iron tablets or if you have been advised to take iron tablets to prevent anaemia.
As pernicious anemia is an autoimmune condition, people may need life-long treatment to control symptoms. Doctors can treat the vitamin B-12 deficiency. However, there is not yet a cure for the immune system reaction that causes this deficiency to occur.
A lack of vitamin B12 can cause neurological problems, which affect your nervous system, such as:

Not getting enough vitamin B12 to the point of a deficiency can cause a variety of serious symptoms including depression, joint pain, and fatigue. Sometimes these effects can be debilitating to the point where you might think you're dying or seriously ill.
Frequent bouts about dizziness and vertigo can indicate B12 deficiency. You may experience a feeling of wobbles when you get up too fast from a sitting position. You may also feel dizzy when you walk up or downstairs, it could also be dangerous.
Disturbed or blurred vision can also occur as a result of a Vitamin B12 deficiency. This happens when the deficiency causes damage to the optic nerve that leads to your eyes. The nervous signal that travels from the eye to the brain is disturbed due to this damage, leading to impaired vision.
Discussion. We found that a higher intake of vitamin B12 was associated with lower systolic and diastolic blood pressure and a higher intake of folic acid was associated with lower systolic blood pressure in children.
Despite the numerous processes in which vitamin B12 is involved, there's little evidence to suggest that it has any influence on weight gain or loss.
Notify the clinic if you experience a rash, severe swelling, dizziness, breathing trouble, congestion, tightness in the chest, pain in the groin or lower legs, swelling of the hands and feet, unusual weakness/fatigue, or chest pain after the injection.
When vitamin B12 levels are low, your hair follicles may not be able to grow new hair as efficiently, resulting in hair loss. A vitamin B12 deficiency can also cause symptoms of anemia, which is associated with low iron levels, hair thinning, and hair loss.
