What will happen to a person whose white blood cells do not function as they should?

A person whose white blood cells do not function as they should has a weakened immune system. This means that they are more susceptible to infections and diseases, and they may have difficulty fighting off even minor illnesses. In some cases, a person with a weakened immune system may develop life-threatening infections.

There are a number of things that can cause white blood cells to not function properly, including:

* Certain medical conditions: Some medical conditions, such as cancer, HIV/AIDS, and diabetes, can damage white blood cells and make them less effective.

* Medications: Some medications, such as chemotherapy and corticosteroids, can also damage white blood cells.

* Radiation therapy: Radiation therapy can also damage white blood cells.

* Nutritional deficiencies: A deficiency of certain nutrients, such as vitamin C, vitamin B6, and folate, can also lead to a weakened immune system.

* Aging: As people age, their immune systems weaken naturally.

If you have a weakened immune system, there are a number of things you can do to reduce your risk of infection, including:

* Wash your hands frequently: This is one of the most important things you can do to prevent the spread of infection.

* Avoid contact with people who are sick: This is especially important if you have a weakened immune system.

* Get vaccinated: Vaccinations can help protect you from a number of serious infections.

* Eat a healthy diet: A healthy diet can help boost your immune system.

* Get enough sleep: Sleep is essential for a healthy immune system.

* Manage stress: Stress can weaken your immune system.

If you have a weakened immune system, it is important to talk to your doctor about ways to protect yourself from infection.
