Pernicious Anemia: Causes, Symptoms, and Treatment

Hello 1-GSM Visitors, have you ever heard of pernicious anemia? It is a type of anemia that occurs when your body lacks vitamin B12. This vitamin is essential for the production of healthy red blood cells. Without it, your body cannot produce enough red blood cells, leading to anemia. In this article, we will discuss the causes, symptoms, and treatment options for pernicious anemia.

Pernicious Anemia

Causes of Pernicious Anemia

Pernicious anemia is caused by a lack of vitamin B12 in the body. The body needs vitamin B12 to make red blood cells. The body cannot produce vitamin B12 on its own. It must be obtained from food or supplements. Pernicious anemia occurs when the body cannot absorb vitamin B12 from the food you eat. This can happen for several reasons.

One of the most common causes of pernicious anemia is an autoimmune condition. Autoimmune conditions occur when the immune system attacks healthy cells in the body. In the case of pernicious anemia, the immune system attacks the cells in the stomach that produce a protein called intrinsic factor. Intrinsic factor is needed for the body to absorb vitamin B12. When these cells are attacked, the body cannot absorb vitamin B12 from the food you eat.

Other causes of pernicious anemia include surgery that removes part of the stomach or small intestine, certain medications, and a diet that is low in vitamin B12.

Symptoms of Pernicious Anemia

The symptoms of pernicious anemia can vary from person to person. Some people may have no symptoms at all, while others may experience severe symptoms. The most common symptoms of pernicious anemia include:

  • Fatigue
  • Weakness
  • Dizziness
  • Shortness of breath
  • Pale skin
  • Heart palpitations
  • Numbness or tingling in the hands and feet
  • Muscle weakness
  • Loss of appetite
  • Weight loss

If left untreated, pernicious anemia can cause serious complications, such as nerve damage, heart disease, and even death.

Treatment of Pernicious Anemia

The treatment for pernicious anemia involves replacing the missing vitamin B12 in the body. This can be done through injections or supplements. Injections of vitamin B12 are usually given once a month. Supplements can be taken in pill form or as a nasal spray.

If the underlying cause of pernicious anemia is an autoimmune condition, treatment may involve medications that suppress the immune system.

It is important to start treatment as soon as possible to prevent complications from occurring. With proper treatment, most people with pernicious anemia can make a full recovery.


Pernicious anemia is a serious condition that can have serious consequences if left untreated. If you are experiencing any of the symptoms of pernicious anemia, it is important to talk to your doctor. Your doctor can perform tests to determine if you have pernicious anemia and develop a treatment plan that is right for you.

Remember, the key to managing pernicious anemia is early detection and treatment. With the right treatment, you can live a healthy and active life.
