Immune System Basics

What Is the Immune System?

The immune system is the body’s defense system against infections and harmful substances. It works to identify and eliminate bacteria, viruses, and other threats.

How the Immune System Works

The immune system uses a network of cells and proteins to:

  • Recognize harmful invaders
  • Respond to infections
  • Protect the body from illness

This process helps maintain overall health.

When the Immune System Overreacts

In some cases, the immune system reacts too strongly to harmless substances, leading to allergies. This can cause symptoms such as sneezing, itching, or inflammation.

When the Immune System Is Weakened

A weakened immune system may lead to:

  • Frequent infections
  • Severe or unusual infections
  • Slower recovery from illness

This may require medical evaluation.

Maintaining Immune Health

Supporting immune health includes:

  • Following medical advice for chronic conditions
  • Staying up to date with vaccinations
  • Maintaining a healthy lifestyle
  • Seeking care when symptoms are persistent or unusual
