Severe Low Neutrophils (Severe Neutropenia)

Severe neutropenia is defined as an absolute neutrophil count (ANC) below 500 cells per microliter of blood. Neutrophils are a type of white blood cell that serve as the body’s first line of defense against bacterial and fungal infections. When neutrophil levels drop this low, the risk of serious, potentially life‑threatening infections rises dramatically, often necessitating urgent medical care Wikipedia.

Patients with severe neutropenia may experience frequent fevers, mouth sores, or signs of infection without the usual inflammatory response (redness, swelling) because neutrophils are critical for initiating these immune reactions Wikipedia. Understanding and managing underlying causes—such as bone marrow disorders, chemotherapy, autoimmune destruction, or nutrient deficiencies—is essential to tailor effective treatment strategies.

Neutrophils are a type of white blood cell that help the body fight infections, especially those caused by bacteria and fungi. They are part of the immune system and act as the body’s first responders. When an infection occurs, neutrophils rush to the site to kill and digest harmful germs.

Neutropenia is a condition where a person has fewer neutrophils than normal. A normal neutrophil count is usually between 1500 and 8000 cells per microliter of blood. If the count drops below 1500, it’s called neutropenia. The condition becomes severe when neutrophils fall below 500 cells per microliter.

Severe neutropenia means the neutrophil count is dangerously low—under 500 cells per microliter. At this level, the immune system is seriously weakened, and the body is highly vulnerable to infections, which can become life-threatening very quickly. Even common bacteria or minor injuries can lead to serious health problems.

Types of Neutropenia

1. Congenital Neutropenia
   This type is inherited and present from birth. A person is born with a genetic issue that limits or blocks neutrophil production.

2. Cyclic Neutropenia
   This rare form causes neutrophil levels to rise and fall in a cycle, usually every 21 days. Symptoms appear when neutrophils are low.

3. Autoimmune Neutropenia
   The immune system mistakenly attacks and destroys neutrophils. It can occur in children or adults.

4. Drug-Induced Neutropenia
   Certain medications can damage the bone marrow or suppress neutrophil production, leading to low counts.

5. Post-infectious Neutropenia
