Autoimmune diseases are chronic conditions, i.e. they are present throughout an individual's life, although the reason for their occurrence is unknown.
However, autoimmune diseases are related to genetic predisposition and environmental factors. Thus, some of the risk factors for this type of pathology are tobacco consumption, sun exposure, virus infections, stressful situations, etc. However, the presence of these factors is not an indication that an autoimmune disease will develop.
In addition, some of these factors can also affect the evolution of the disease causing a greater tendency to suffer an outbreak.
