Neutropenia – Definition, Symptoms, Causes & Treatment

Neutropenia occurs when a person has low levels of neutrophils. Neutrophils are a type of white blood cell. All white blood cells help the body fight infection.

Neutropenia – Definition, Symptoms, Causes & Treatment 

Neutropenia Definition:-

Neutropenia can be caused by diseases that damage the bone marrow, any infection, or medication. There may not be visible symptoms than an increased vulnerability to infection or a weak immune system.


Management of the condition involves treating the underlying cause, as well as medication that increases neutrophil counts. Avoiding anyone who is ill and practicing good hygiene can help reduce the risk of infection.


Neutrophils, produced in the bone marrow, fight infection by destroying harmful bacteria and fungi (yeast) attacking the body. 


It is not a disease, but a condition in which the body lacks neutrophils, occurring

  • Sharp, meaning it came on suddenly.

  • Chronic, which means that it is long.

  • Cyclic, which means that it comes and goes.

Identification of a professional neutrophilia:-

Neutrophils are the primary white blood cells that respond to a bacterial infection, so the most common cause of neutrophilia is a bacterial infection. Also-


  • Neutrophilia is an increase in circulating neutrophils above that expected in a healthy person of the same age, sex, race, and physical condition.

  • It represents an increase in the number of neutrophils above 7.5 x 109 / l and is one of the most frequently observed changes in FBC.

Let’s know the symptoms of neutropenia:-

Symptoms of neutropenia can range from mild to severe. The lower the level of neutrophils, the more intense the symptoms will be.

Typical symptoms include:

  • High fever

  • Pneumonia

  • Sinus infection

  • Otitis media, or an ear infection

  • Gingivitis

  • Omphalitis, or navel infection

Types of chronic illness:-

Neutropenic fever-

A single oral temperature is higher than 38.3 (C (101) F) or 38.0 (C (100.4 JO F), which lasts more than 1 hour in a patient with neutropenia.


On initial evaluation, for the risk of complications from a severe infection, each patient should be medically evaluated.


An appropriate risk assessment can determine the type of empirical therapy, duration of antibiotic treatment, and inconsistent versus inconsistent management.

Febrile neutropenia- 

The development of fever accompanied by other signs of infection is due to an abnormally low number of neutrophil granulocytes in the blood.


The term neutropenic sepsis is also applied, although used for patients who are sick. Bacteria in the bloodstream are present in about 20% of all patients with this condition.

  • Febrile neutropenia can create any other type of neutropenias.

  • It is most commonly recognized as a complication of chemotherapy when it is myelosuppressive. 

  • It suppresses the bone marrow by forming blood cells.

Cyclic neutropenia-

It is a rare blood disorder, characterized by recurrent episodes due to low levels of white blood cells (neutrophils) in the body. Neutrophils help to destroy bacteria entering the body and fight infection from the surroundings.

Symptoms associated with cyclic neutropenia:-

  • Fever, a general feeling of ill health and lesions of the mucous membrane of the mouth.

  • In most cases, individuals with low levels of neutropenia are unusually susceptible to recurrent infections.

Autoimmune neutropenia-

There is a form of neutropenia that is most common in infants and young children. Where the body recognizes neutrophils as enemies and produces antibodies to destroy them.


  • Primary autoimmune neutropenia, another name for autoimmune neutropenia, is an autoimmune disease first reported in 1975 that occurs primarily in childhood.

  • In immune system neutropenia, indescribable morphology produces antibodies coordinated against neutrophilic protein antigens in white platelets, known as granulocytic neutrophils, granulocytes, neutrophils, segments, polyunsaturated neutrophils, or polis.

  • These antibodies, IgG antibodies, destroy granulocytic neutrophils. As a result, granulocyte neutrophil white blood cell levels are lower in patients with autoimmune neutropenia, leading to a condition of neutropenia.

Neutropenic sepsis-

It occurs when a patient with a low level of neutrophils gets an infection that they cannot fight and becomes septic.


Nonavailability in receiving immediate medical treatment can cause death. Signs of the disease may not be visible, so patients with chemotherapy or other immunosuppressant therapy need to notice the following symptoms:

  • Generally unwell

  • flu-like symptoms

  • fever

  • Shiver

  • To sweat

  • Sore throat

  • Diarrhea.


Medical feasibility of neutropenia:-


Neutropenic fever icd 10 code> D50-D89 Diseases of the blood and blood-forming organs and some disorders associated with the immune system> D70-D77 Blood and other disorders of blood-forming organs> D70-neutropenia: 2020 PCD-10-CM Diagnosis Code Is D70.9.


  • D70.9 is a billable code used to specify the medical diagnosis of neutropenia. It is valid for the year 2020 to present transactions covered by HIPAA. 

  • Neutropenia ICD 10 code is utilized to depict conditions like, obtained eosinopenia, gained neutropenia, agranulocytosis, agranulocytosis, AIDS-related agranulocytosis, amiable granulocytopenia in adolescence, and so forth.


Diagnostic information that confirms the problem-

  • Reduction in the number of neutrophils found in the bloodstream.

  • Reduction in the neutrophilic leukocytes.

Guidelines for DIY neutropenic precautions at home:-

If you have mild neutropenia, you can stay at home until your neutrophil levels return to normal. However, to protect yourself from germs here is what you can do at home

  • Washing hands – Before using the washroom or after eating something, cleaning your hands more often. 

  • Yes! Clean body – Daily bathing, be sure to clean sweaty areas such as your feet and waist.

  • Dental care – Practice good oral care by brushing your teeth before eating and bed. Using a soft toothbrush and brush gently is suggested.

  • No injury – Do your best to avoid cuts and scratches. Do not use sharp objects, and be sure to wear gloves when cleaning.

  • Give you specific foods – When you are neutropenic, you cannot eat foods that may contain bacteria, such as crippled fruits or rare-cooked meats. Employees may put you on a neutropenic diet.

  • Avoid anal therapy procedures – The rectal area is sensitive, so the staff will not give you a suppository or enema.

  • Do not use tampons – Since they pose a risk for toxic shock syndrome and infection, it is best to use a pad.

Neutropenic diet for patients should and should not be given:-

Food options to choose-

The foods you are allowed to eat on a neutropenic diet include  

  • Vegetables – All cooked or frozen vegetables.

  • Fruit – All canned and frozen fruits and fruits.

  • Juice – Thick-skinned fruits such as bananas, oranges, and grapes were washed and peeled well.

  • Protein – Fully cooked meats and canned meats. Alternatives to hard-cook or boiled eggs and pasteurized eggs.

The vital neutropenic diet includes changes to prevent the intake of harmful bacteria with foods and beverages. This diet is specifically for people with neutropenia but is also an implemented diet for people with cancer and a weakened immune system.


Wrapping up:-


To mention our focus on neutropenia, it can last for months or years. Running for less than three months is called acute, but for a long period, it is called chronic.


In a study conducted in Denmark, more than 370,000 people revealed the presence of neutropenia. Low neutrophil levels can cause dangerous infections.


These infections can be fatal when they are left untreated, so it is best to consult a doctor for a proper diagnosis. For more information, stay connected with the team OnlyHealthCare for more health-related feed.
