Neutropenia
Urgent
Neutropenia is a condition in which the number of neutrophils, a type of white blood cell that helps fight infections, is lower than normal. It can be temporary or persistent and may occur as a result of infection, medicines, cancer treatment, immune disorders, nutritional problems, bone marrow conditions, or inherited factors. Mild neutropenia may cause no symptoms, while more severe neutropenia can increase the risk of serious bacterial or fungal infections.

When to Seek Medical Attention
Neutropenia requires medical assessment because a low neutrophil count can increase the risk of serious infection. Seek urgent medical attention for fever, chills, sore throat, new cough, painful urination, skin infection, or other signs of infection, particularly when neutrophil counts are very low. Emergency care is needed for severe infection, difficulty breathing, confusion, fainting, or rapidly worsening illness.

Overview
Neutropenia is a condition in which the number of neutrophils, a type of white blood cell that helps fight infections, is lower than normal. It can be temporary or persistent and may occur as a result of infection, medicines, cancer treatment, immune disorders, nutritional problems, bone marrow conditions, or inherited factors. Mild neutropenia may cause no symptoms, while more severe neutropenia can increase the risk of serious bacterial or fungal infections.

Fever
Poor Concentration
Causes 3
Neutropenia can develop when the bone marrow does not produce enough neutrophils, when neutrophils are destroyed or removed from the bloodstream too quickly, or when they are used up during severe infection. Medicines and cancer treatments can suppress bone marrow production. Viral and other infections, autoimmune disorders, nutritional deficiencies, bone marrow diseases, and inherited conditions can also cause neutropenia. In some people, no specific cause is found.

Chronic Disease
Infection
Risk Factors
Risk depends on the underlying cause. People receiving chemotherapy, radiation, or medicines that suppress bone marrow or immune function may be at increased risk. Certain infections, autoimmune diseases, nutritional deficiencies, blood or bone marrow disorders, and inherited conditions can also increase risk. Severe illness may cause neutrophils to be consumed faster than the body can replace them. Some individuals have persistent mild neutropenia without frequent infections.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is based on a complete blood count with a differential to determine the number and proportion of neutrophils and other blood cells. The healthcare professional may review medicines, recent infections, medical conditions, and family history to identify a possible cause. Depending on the findings, additional blood tests, antibody testing, nutritional studies, or a bone marrow examination may be needed. Repeated blood counts can help determine whether neutropenia is temporary or persistent.
Prevention
Key Prevention Tips
Neutropenia itself cannot always be prevented because many causes are unavoidable or related to underlying medical conditions
When a medicine or cancer treatment can lower neutrophil counts, healthcare professionals may monitor blood counts and adjust treatment when necessary
Treating infections and managing underlying conditions can reduce complications
People known to have significant neutropenia may receive individualized advice about infection prevention and should seek prompt medical attention for signs of infection
Prevention Guidance
Neutropenia itself cannot always be prevented because many causes are unavoidable or related to underlying medical conditions. When a medicine or cancer treatment can lower neutrophil counts, healthcare professionals may monitor blood counts and adjust treatment when necessary. Treating infections and managing underlying conditions can reduce complications. People known to have significant neutropenia may receive individualized advice about infection prevention and should seek prompt medical attention for signs of infection.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
