Chronic inflammation is often called
the "silent killer."
Temporary (or acute) inflammation is a necessary function of good health. You cut your finger, for example, and your immune system goes into action rushing white blood cells to the area to protect the finger from foreign invaders. The inflammation protects and helps nourish the injured finger back to health.
Chronic (long-term) inflammation, however, is another matter. Chronic inflammation is harmful to the body and may contribute to many diseases. There can be very few, if any, symptoms of chronic inflammation; hence the name the "silent killer."
Chronic inflammation smolders like an inactive volcano, then one day erupts with symptoms, but often it is too late, resulting in a heart attack, cancer, diabetes, Alzheimer's, or other diseases.
There can be many things that trigger chronic inflammation, one major culprit is excess body fat.
