What Is Sideroblastic Anemia? Blood Disorder Explained
Written by Medicover Team and Medically Reviewed by Dr Lavanya Garapati , Hematologists
Sideroblastic anemia, also known as a mitochondrial disorder of red blood cells, is a rare condition where the bone marrow produces abnormal red cells called ringed sideroblasts.
These cells fail to carry oxygen effectively due to defective hemoglobin production.
What are the Sideroblastic Anemia Symptoms and Warning Signs?
The symptoms may differ depending on the severity of the condition, the age of the patient, and the underlying cause. Some people may have mild symptoms at first, while others may experience more noticeable health problems.
Common Symptoms of Sideroblastic Anemia
- Constant tiredness or fatigue
- Feeling weak or low on energy
- Pale or yellowish skin
- Shortness of breath, even with mild activity
- Fast or irregular heartbeat
These signs often appear gradually. Many patients may dismiss them as general tiredness, but over time, they can worsen and affect daily activities.
Severe Symptoms of Sideroblastic Anemia
In more serious cases, additional symptoms may develop:
- Enlarged spleen (felt as fullness or pain in the upper left abdomen)
- Heart rhythm problems
- Poor growth (especially in children)
- Numbness or tingling (due to low vitamin B6)
If you or a loved one experiences prolonged fatigue, pale skin, or shortness of breath without a known cause, consult a hematologist promptly.
What are the Different Types of Sideroblastic Anemia?
Sideroblastic anemia is classified into two major types: congenital (inherited) and acquired (developed later in life). Each type has different causes and may require different treatments.
Congenital Sideroblastic Anemia (CSA)
This type is genetic and usually appears early in life.
- X-linked: Caused by changes in the ALAS2 gene
- Autosomal recessive: Linked to defects in the SLC25A38 gene
Children with congenital sideroblastic anemia may require long-term care and regular monitoring of growth and development.
Acquired Sideroblastic Anemia
This type develops due to other conditions or exposures.
- Primary: Often linked to myelodysplastic syndromes (MDS)
- Secondary: Caused by alcohol, certain medicines, or vitamin/mineral deficiencies
Treatment for acquired types usually focuses on managing the underlying cause and improving red blood cell health.
What are the Common Causes and Risk Factors of Sideroblastic Anemia?
Understanding what leads to sideroblastic anemia can help with early management and prevention.
This condition happens when the bone marrow produces abnormal red blood cells that cannot use iron properly, leading to anemia.
Sideroblastic Anemia Causes
Sideroblastic anemia can be inherited (genetic) or acquired later in life. Here are the main causes:
- Genetic Mutations: Changes in genes like ALAS2, SLC25A38, and ABCB7 are linked to inherited forms of the disease. These mutations affect how the body produces hemoglobin.
- Long-Term Alcohol Use: Excessive alcohol interferes with bone marrow function and vitamin B6 metabolism, both of which are important for red blood cell production.
- Certain Medications: Drugs such as isoniazid (used for tuberculosis) and chloramphenicol (an antibiotic) can damage the bone marrow and lead to anemia.
- Vitamin and Mineral Deficiencies: Low levels of vitamin B6 or copper can impair red blood cell formation.
- Bone Marrow Disorders: Conditions like myelodysplastic syndromes (MDS) can affect how red blood cells mature, leading to sideroblastic anemia.
Sideroblastic Anemia Risk Factors
Some people are more likely to develop this condition due to the following risk factors:
- Family History of Blood Disorders: Inherited gene mutations can increase the risk of developing this type of anemia.
- Heavy Alcohol Consumption: Regular alcohol use over time affects nutrient absorption and bone marrow health.
- Long-Term Use of Certain Medications: Prolonged use of drugs that affect bone marrow or vitamin levels can raise the risk.
- Poor Nutrition: Diets low in essential nutrients, particularly vitamin B6 and copper, can increase susceptibility.
- Exposure to Toxins: Being exposed to substances like lead can interfere with how the body uses iron.
Health Tip: If you have a family history of blood disorders or face nutritional challenges, regular health checkups and a balanced diet can help reduce your risk.

Get Second OpinionHow is Sideroblastic Anemia Diagnosed?
Early diagnosis is important for managing sideroblastic anemia and preventing complications. Doctors rely on a combination of blood tests and bone marrow evaluation to identify the condition.
Diagnostic Tests for Sideroblastic Anemia
- Peripheral Blood Smear: Examines red blood cells for size, shape, and colour changes.
- Bone Marrow Biopsy: Confirms the presence of ringed sideroblasts (iron-loaded cells).
- Genetic Testing: Checks for gene changes like ALAS2 mutations.
- Complete Blood Count (CBC): Measures red blood cell levels and hemoglobin.
- Iron Studies: Tests iron, ferritin, and total iron-binding capacity (TIBC).
These tests help doctors determine the type and cause of sideroblastic anemia and plan the most effective treatment.
What are the Treatment Options for Sideroblastic Anemia?
Treatment depends on whether the condition is congenital (inherited) or acquired (developed later in life). A personalised treatment plan is important to manage symptoms, support red blood cell production, and control iron levels.
Treatment for Congenital Sideroblastic Anemia
This type is caused by genetic mutations and often appears in infancy or early childhood. The main focus is to support healthy red blood cells and manage iron overload.
Common Treatments
Vitamin B6 (Pyridoxine):
Some inherited forms respond well to high doses of vitamin B6. This vitamin helps the body make red blood cells. Regular follow-ups are needed to check effectiveness and avoid side effects.
Iron Chelation Therapy:
Due to repeated blood transfusions, excess iron can build up in the body. Chelation therapy helps remove extra iron and protects organs like the heart and liver.
Blood Transfusions:
In severe cases, transfusions are needed to boost hemoglobin and reduce fatigue and breathlessness.
Stem Cell Transplant (in select cases):
For some children or young adults with severe symptoms, a bone marrow transplant may offer a long-term cure. This depends on the patient's health and the availability of a suitable donor.
Treatment for Acquired Sideroblastic Anemia
This form appears later in life and may be caused by certain medications, alcohol use, nutrient deficiencies, or conditions like myelodysplastic syndromes (MDS).
Key treatments include
Stopping Harmful Medications:
Some medicines can affect bone marrow function. With your doctor's guidance, changing or stopping these medications can help improve red blood cell production.
Avoiding Alcohol:
Chronic alcohol use can damage the bone marrow. Stopping alcohol with medical or counselling support can lead to better blood cell counts.
Copper Supplements:
A lack of copper in the body can lead to anemia. Supplements help restore copper levels and improve red cell production if a deficiency is found.
Erythropoiesis-Stimulating Agents (ESAs):
These medicines boost red blood cell production in the bone marrow. They are often used for people with MDS-related sideroblastic anemia.
Iron Chelation Therapy:
Like in congenital cases, iron levels may need to be managed if there is iron overload from transfusions or poor red cell recycling.
Treating Underlying MDS:
If MDS is the cause, treatment may include supportive care, medicines, or a bone marrow transplant, depending on the patient's age and overall health.
Recovery Time
Most patients improve within a few weeks to months. Regular follow-ups help track progress and adjust treatment if needed.

What is the Recovery Process After Sideroblastic Anemia Treatment?
Recovery from sideroblastic anemia depends on the type of anemia, how early it is diagnosed, and how well the body responds to treatment. While some people recover quickly, others may need long-term care and support. The goal of recovery is to manage symptoms, improve quality of life, and prevent complications.
What to Expect During Recovery
- Regular checkups: To monitor hemoglobin and iron levels
- Nutritional support: Focus on getting enough vitamin B6 and copper
- Lifestyle changes: Avoid alcohol and toxins
- Long-term care: Some may need transfusions or iron-reducing treatment
What Precautions Can Help Prevent Sideroblastic Anemia?
While not all cases of sideroblastic anemia can be prevented, especially genetic one,s some lifestyle habits and early health monitoring can lower your risk of developing it.
Sideroblastic Anemia Prevention Tips
- Eat a healthy diet rich in vitamin B6 and copper
- Don't take medications long-term without your doctor's advice
- Avoid heavy alcohol use
- Get regular health checkups if you're at risk
These small steps can make a big difference in keeping your blood healthy and reducing the chances of anemia.
Possible Complications If Untreated
Without proper diagnosis and treatment, sideroblastic anemia can lead to serious health problems. The body may continue to produce faulty red blood cells, and excess iron can build up over time.
- Iron overload in the body
- Damage to organs like the liver and heart
- Higher risk of leukemia (in MDS-related cases)
- Severe tiredness and lower quality of life
Recognizing the symptoms early and getting appropriate treatment can help avoid these complications and support a healthier future.
