3A01.3: Vitamin B12 deficiency anaemia due to intrinsic factor deficiency

ICD-11 code 3A01.3 refers to Vitamin B12 deficiency anaemia due to intrinsic factor deficiency. This specific code identifies a form of anemia that results from the body’s inability to absorb Vitamin B12 properly. Intrinsic factor is a protein produced in the stomach that is necessary for the absorption of Vitamin B12. When intrinsic factor is deficient, the body is unable to effectively utilize Vitamin B12, leading to anemia.

Vitamin B12 deficiency anemia due to intrinsic factor deficiency can have serious health implications if left untreated. Symptoms of this condition may include fatigue, weakness, pale skin, and shortness of breath. In severe cases, neurological symptoms such as numbness or tingling in the hands and feet, difficulty walking, and cognitive impairment may also occur.

Diagnosis of Vitamin B12 deficiency anemia due to intrinsic factor deficiency typically involves blood tests to measure Vitamin B12 levels and assess for the presence of intrinsic factor antibodies. Treatment for this condition usually involves regular injections of Vitamin B12 to bypass the absorption issues caused by intrinsic factor deficiency. It is important for individuals with this form of anemia to work closely with a healthcare provider to monitor their condition and ensure proper management.

In severe cases, individuals may develop neurological symptoms such as numbness or tingling in the hands and feet, muscle weakness, and difficulty walking.

Mental symptoms may also manifest in those suffering from Vitamin B12 deficiency anaemia due to intrinsic factor deficiency. These symptoms can include memory loss, confusion, and cognitive difficulties. Some patients may also experience mood changes, such as depression or irritability. Additionally, individuals with this condition may have trouble concentrating and may exhibit behavioral changes.

Gastrointestinal symptoms are another hallmark of 3A01.3. These symptoms can include loss of appetite, weight loss, and diarrhea. Patients may also experience a sore tongue, mouth ulcers, or a reduced sense of taste. Some individuals may have an enlarged liver or spleen, as well as gastrointestinal disturbances such as constipation or gas. Overall, the symptoms of Vitamin B12 deficiency anaemia due to intrinsic factor deficiency can vary in severity and can significantly impact an individual’s quality of life.

🩺  Diagnosis

Diagnosis of 3A01.3, Vitamin B12 deficiency anemia due to intrinsic factor deficiency, often begins with a physical examination and review of medical history. Symptoms such as fatigue, weakness, pale skin, and shortness of breath may prompt further investigation.

Laboratory tests are essential in diagnosing Vitamin B12 deficiency anemia. A complete blood count (CBC) can reveal low levels of red blood cells and hemoglobin, while a peripheral blood smear may show enlarged red blood cells. Serum Vitamin B12 levels can also be measured to confirm a deficiency.

In addition to laboratory tests, doctors may perform other diagnostic procedures to determine the cause of the deficiency. A Schilling test, which measures how well the body absorbs Vitamin B12, can help identify intrinsic factor deficiency. Gastrointestinal evaluations may also be recommended to assess the health of the digestive system.

💊  Treatment & Recovery

Treatment for Vitamin B12 deficiency anaemia due to intrinsic factor deficiency typically involves vitamin B12 supplementation. This can be administered orally, subcutaneously, or intramuscularly, depending on the severity of the deficiency and the individual’s ability to absorb the vitamin. In some cases, high-dose injections may be necessary to replenish the body’s stores of vitamin B12 quickly.

Recovery from Vitamin B12 deficiency anaemia due to intrinsic factor deficiency depends on the individual’s response to treatment and the extent of the deficiency. Regular monitoring of vitamin B12 levels through blood tests is crucial to ensure that levels are adequately maintained. It is important for individuals with this condition to adhere to their treatment plan and follow up with their healthcare provider regularly to prevent relapse.

In some cases, individuals with severe Vitamin B12 deficiency anaemia due to intrinsic factor deficiency may require additional support such as dietary counseling or nutritional supplementation. Maintaining a diet rich in vitamin B12 sources, such as meat, fish, dairy products, and fortified cereals, can help prevent future deficiencies. Some individuals may also benefit from working with a dietitian to create a personalized nutrition plan to support their recovery and overall health.

🌎  Prevalence & Risk

In the United States, Vitamin B12 deficiency anaemia due to intrinsic factor deficiency, classified as 3A01.3, is considered relatively rare. However, it is estimated that approximately 1.5-2% of adults over the age of 50 may be affected by this condition. This prevalence is higher among certain populations, such as individuals with gastrointestinal disorders that affect absorption of vitamin B12.

In Europe, the prevalence of 3A01.3 is slightly higher compared to the United States. Studies have shown that up to 3% of adults over the age of 60 may have intrinsic factor deficiency leading to vitamin B12 deficiency anaemia. This may be attributed to differences in dietary habits, genetic factors, and overall population demographics across European countries.

In Asia, the prevalence of Vitamin B12 deficiency anaemia due to intrinsic factor deficiency is not well studied. However, it is generally believed that the condition may be underdiagnosed in Asian populations due to differences in healthcare systems, access to medical care, and awareness of the condition among healthcare providers. Further research is needed to determine the true prevalence of 3A01.3 in Asian countries.

In Australia, similar to Europe, the prevalence of 3A01.3 is slightly higher compared to the United States. While specific data on the prevalence of intrinsic factor deficiency leading to vitamin B12 deficiency anaemia is limited, it is estimated that around 3-4% of older adults in Australia may be affected by this condition. This highlights the importance of considering intrinsic factor deficiency as a potential cause of vitamin B12 deficiency anaemia in clinical practice across different regions.

😷  Prevention

Prevention of 3A01.3 (Vitamin B12 deficiency anaemia due to intrinsic factor deficiency) can be achieved through a combination of dietary changes and medical interventions. One of the most effective ways to prevent this type of anemia is to ensure an adequate intake of vitamin B12 through a balanced diet that includes foods high in this nutrient such as meat, fish, eggs, and dairy products. Consuming fortified foods or taking vitamin B12 supplements can also help prevent deficiency in individuals who are at risk.

Another important aspect of preventing 3A01.3 is to address any underlying medical conditions that may be affecting the absorption of vitamin B12 in the body. Disorders such as pernicious anemia, atrophic gastritis, or conditions affecting the ileum can interfere with the absorption of vitamin B12 and lead to deficiency. Managing these conditions through proper medical treatment and monitoring can help prevent the development of intrinsic factor deficiency anemia.

Regular monitoring of vitamin B12 levels through blood tests can also aid in the prevention of 3A01.3. Individuals at risk of developing this type of anemia, such as older adults, individuals with gastrointestinal disorders, or strict vegetarians, should work with their healthcare provider to monitor their vitamin B12 levels and adjust their diet or supplementation as needed. Early detection and intervention can help prevent the progression of intrinsic factor deficiency anemia and its associated complications.

Another disease similar to 3A01.3 is pernicious anemia (ICD-10 code D51). Pernicious anemia is a type of megaloblastic anemia caused by a deficiency of intrinsic factor, leading to impaired absorption of vitamin B12. This disease can result in symptoms such as fatigue, weakness, pale skin, and neurological problems.

Additionally, subacute combined degeneration of spinal cord (ICD-10 code G32) shares similarities with 3A01.3. This condition is characterized by degeneration of the spinal cord due to a lack of vitamin B12, often caused by an intrinsic factor deficiency. Patients with subacute combined degeneration of the spinal cord may experience symptoms such as numbness, tingling, difficulty walking, and muscle weakness.

Furthermore, post-gastrectomy vitamin B12 deficiency (ICD-10 code E89.2) is another relevant disease to mention in relation to 3A01.3. This condition occurs in patients who have undergone gastric surgery, leading to a decreased production of intrinsic factor necessary for vitamin B12 absorption. Patients with post-gastrectomy vitamin B12 deficiency may develop symptoms similar to those of intrinsic factor deficiency anemia, including anemia, fatigue, and neurological problems.
