How to Raise Neutrophils

Last Updated: December 21, 2024 Fact Checked

Neutrophils are a type of white blood cell that helps your body fight infection. You may develop low levels of neutrophils, a condition called neutropenia, if you have cancer or are undergoing treatment for cancer, such as chemotherapy. You can also develop neutropenia due to a poor diet, a blood-related disease, or a bone marrow infection. To raise neutrophils in your body, you can adjust your diet and use medical treatments to address the issue. You should also take steps to stay healthy and avoid germs or bacteria, as you will be more susceptible to catching an infection or illness when your neutrophil levels are low.^{[1]

Foods like salmon, mackerel, and flax oil are all high in omega-3 fatty acids. Fatty acids increase your levels of neutrophils and phagocytes, which are white blood cells that consume bad bacteria in your body. Add these foods to your diet and cook with flax oil, or have ¹⁄₂ teaspoon (2.5 mL) of flax oil once a day.^{[9]

Use prescription nutritional supplements after talking to your doctor. If your diet is poor or you have a poor appetite, you may want to take a multivitamin or supplements to help your body in making white blood cells. However, always talk to your doctor or healthcare provider before taking any vitamins or supplements. They may recommend a prescription drink to augment your diet.^{[14]

1
Ask your doctor for a prescription for neutrophil-boosting medication. Medications like Neupogen can help to raise your neutrophil levels, especially if you are undergoing treatment for cancer. Your doctor can give you this medication with an injection or through an IV. You may receive it daily if your neutrophil levels are very low and you are undergoing chemotherapy.^{[17]

- You may experience side effects like nausea, fever, bone pain, and back pain while on this medication.
Neutropenia can be caused by other conditions like a bacterial infection or a virus. Your doctor may treat these issues by hospitalizing you and giving you antibiotics to treat the underlying infection. Once the infection clears up, your neutrophil levels should return to normal.^{[18]

Get a bone marrow transplant if your condition becomes severe. If your low neutrophil levels are due to a disease like leukemia or aplastic anemia, your doctor may suggest a bone marrow transplant. The transplant is done by removing diseased bone marrow and replacing it with healthy bone marrow from a donor. You will be under general anesthesia during the procedure.^{[19]

1
Wash your hands regularly with warm water and antibacterial soap. Proper hand washing can go a long way to prevent exposure to infections and germs, especially if your immune system and neutrophil levels are low. Scrub your hands with soap and water for 15-30 seconds. Then, rinse them well under warm, running water and dry your hands well with a paper towel.
- Make sure you wash your hands before eating, drinking, or taking medicine, and after using the bathroom. Wash your hands before touching food or any parts of your body, especially your eyes, nose, and mouth.
- Always wash your hands after touching pets or animals.

Wear a face mask to prevent exposure to germs and bacteria. Protect your mouth and nose by wearing a face mask when you go outside or to public places, especially anywhere with large crowds. You can also wear a face mask at home if you live with others or your living space is dusty, moldy, or dirty.^{[20]
