Neutropenia is a medical condition characterized by a low count of neutrophil white blood cells in the bloodstream. Neutrophils are an important type of white blood cell that help the body fight infections. When a person has neutropenia, they are more susceptible to infections, which can range from mild to severe and life-threatening.

Causes of neutropenia include:

1. Certain medications, such as chemotherapy drugs

2. Certain medical conditions, such as cancer, autoimmune disorders, and bone marrow disorders

3. Radiation therapy

4. Vitamin B12 or folate deficiency

5. Infections

Symptoms of neutropenia may include:

1. Fever

2. Chills

3. Sore throat

4. Mouth sores

5. Skin infections

6. Fatigue

Treatment for neutropenia depends on the underlying cause and may include antibiotics to treat infections, medication to increase the production of white blood cells, or changes to medications that may be causing the condition. In some cases, a bone marrow transplant may be recommended.

It is important to see a doctor if you experience symptoms of neutropenia, as prompt diagnosis and treatment can help prevent serious infections and improve overall health outcomes.
