Pernicious anemia is a type of autoimmune condition. It leads to a lack of Vitamin B12 in the body. Because the small intestine can’t absorb enough Vitamin B12, red blood cells decrease.
This leads to symptoms like tiredness, weakness, and pale skin. In severe cases, problems with walking, nerve pain, and memory can happen.
An autoimmune issue stops the stomach from making intrinsic factor. This substance is necessary for absorbing Vitamin B12. Pernicious anemia is not common but affects 1.9% of people over 60.
The main treatment is with Vitamin B12 shots. People might need these regularly or take pills. It’s important to see a doctor for the right diagnosis and care.
Key Takeaways:
- Pernicious anemia is an autoimmune condition resulting in Vitamin B12 deficiency.
- Symptoms of pernicious anemia include fatigue, weakness, neurological issues, and pale skin.
- It is caused by an autoimmune process affecting the production of intrinsic factor.
- Treatment involves Vitamin B12 injections to restore levels and continued supplementation.
- Consulting with a healthcare professional is essential for proper diagnosis and management.
Causes and Risk Factors of Pernicious Anemia
Pernicious anemia is when the body can’t take in enough Vitamin B12. It’s caused by inflammation in the stomach. This inflammation stops the body from absorbing Vitamin B12 in the small intestine. The disease also stops the stomach from making intrinsic factor, which is a must for taking in Vitamin B12 from food.
Genes also affect whether someone gets pernicious anemia. People with certain genes are at higher risk. This condition often comes along with other diseases like type 1 diabetes, Addison’s, and Grave’s diseases.
Some things make it more likely to get pernicious anemia. If it runs in your family, you might have a higher chance of getting it. People from Northern European or Scandinavian backgrounds are also more at risk.
Autoimmune problems raise the risk of pernicious anemia too. Diseases like type 1 diabetes or Addison’s can make it more likely to happen. Also, surgeries on the stomach that change how it works can lead to Vitamin B12 problems.
Pernicious anemia affects more elderly people than others. People over 60 have a greater risk. The link might be due to the digestive system changing with age. This makes it harder for the body to absorb Vitamin B12.

Diagnosing and Treating Pernicious Anemia
To diagnose pernicious anemia, several tests are needed. These tests are important in finding out the condition. They include:
- Complete Blood Count (CBC) – This test checks for anemia. It looks at the number of red blood cells, white blood cells, and platelets. Low red blood cell count may show anemia.
- Vitamin B12 Level Test – This measures how much Vitamin B12 is in your blood. It helps detect if there’s a deficiency. Pernicious anemia often leads to low Vitamin B12 levels.
- Intrinsic Factor and Parietal Cell Antibodies – Testing these antibodies can tell if pernicious anemia is causing the Vitamin B12 problem. If these antibodies are present, it means an immune response affects the stomach’s cells.
After a diagnosis, treating pernicious anemia means dealing with the Vitamin B12 issue. Treatments include:
- Vitamin B12 Injections – Doctors often give Vitamin B12 shots. These can be daily or weekly until B12 levels get better.
Then, they might be less often. Some might need these shots for life if their body doesn’t absorb B12 well. - Oral Supplementation – For mild cases or those who like pills, there are oral B12 supplements. These pills fill up B12 levels and keep them right.
Not treating pernicious anemia can cause problems. These include:
- Gastric Cancer – Lack of Vitamin B12 for a long time could raise your chance of getting stomach cancer.
- Peripheral Nerve Damage – It can hurt the nerves in your arms and legs. This causes tingling, numbness, and weakness in muscles.
- Digestive Tract Problems – You might have stomach issues like diarrhea, constipation, or not wanting to eat.
- Memory Issues – It could make you forget things or have trouble focusing.
- Heart Problems – Without enough Vitamin B12, your heart might not work as well. This can lead to heart diseases.
It’s key to treat pernicious anemia to avoid these issues. Long-term care and keeping an eye on Vitamin B12 levels are important. Visiting your doctor regularly is a must. This is how you keep pernicious anemia in check and adjust your treatment as needed.
Conclusion
Pernicious anemia is a rare disease related to not having enough Vitamin B12. It leads to issues like tiredness, weak muscles, and problems with the nervous system. People with this condition often have pale skin.
Getting diagnosed early and starting treatment is very important. Usually, the treatment includes Vitamin B12 shots. Sometimes, people also need to take more Vitamin B12 by mouth.
New treatments, like using stem cells, are also under study. This method might be a good way to help the body make more red blood cells. But, we need to learn more about how well it works and its benefits.
By managing pernicious anemia well, people can live healthier lives. Staying under a doctor’s care is key for anyone with this condition.
