Inflammation is the reaction of the stereotypical immune system to external (infection, trauma, burn, allergy, etc.) or internal (cancer cells) aggression.

Inflammation is a set of reactions generated by the body in response to an attack. This can be external like an injury, infection, trauma, or internal like those observed in autoimmune pathologies.

Inflammatory reactions are triggered in order to defend the body against aggression. When they are visible, they are classically manifested by 4 clinical signs: redness, pain, swelling and increased local heat. It may be a cutaneous or subcutaneous inflammation (abscess, erysipelas, shock). When the inflammation is internal, these signs exist but are not visible. Only pain is felt, often increased in intensity during the night.

In some cases, the inflammation may persist until it becomes chronic. The immune system is then overwhelmed. It is no longer beneficial at all and needs to be diagnosed and treated. This is the case with chronic inflammatory diseases, such as rheumatoid arthritis or Crohn's disease.

A recent, particularly landmark study now provides us with the strongest evidence to date showing that inflammation plays an important role in heart disease and that a large number of newly identified genetic risk factors are involved in this process. Alzheimer's disease, characterized by destruction of neurons, is also thought to be inflammatory in origin

Everyone knows that aging is not a disease in itself, but it inevitably brings its share of chronic conditions. These all have the same root, subchronic inflammation.

Chronic inflammation is a response to many changes in the modern environment and behavior, it is favored by sedentary lifestyle, poor food hygiene (junk food), pollution, alterations in the human microbiota) and an important factor in development diseases of civilization such as insulin resistance, obesity, cardiovascular disease, immune disease, and even mood and behavior disorders.

The inflammatory response is a complex phenomenon, which can sometimes be relieved by the use of anti-inflammatory molecules, and by an improved lifestyle.
