Immunological diseases

The immune system is a defense and adaptation system of our body in relation to the external environment. It allows us to distinguish what we accept and what we do not from everything around us—foods, germs, chemical substances, our own aged or damaged cells, etc.—in order to preserve good health. All disorders caused by either an excess or a deficiency of this function are included within these diseases.

It has two fundamental components: innate immunity, which depends on the genes of our species and does not need to be trained to function, and acquired immunity, which depends on the learning process of our body through contact with infections, foods, or chemical substances. Both work together in close collaboration and in a delicate balance.

Fibromyalgia

Fibromyalgia is a condition that is part of the so-called central sensitization syndromes. There is a hyperexcitation of the central nervous system with a lowered pain threshold, which causes pain to appear earlier and become more intense, longer-lasting, and more widespread.

Generalized pain is often accompanied by other symptoms, such as fatigue or sleep disturbances. It is diagnosed based on criteria that rely on symptoms and physical examination. There is no specific medical test.

Sjögren's Syndrome

Sjögren's Syndrome is a chronic, systemic autoimmune disease, the cause of which is unknown. Its main symptoms are a dry mouth (xerostomia) and dry eyes (xerophthalmia). In this disease, the cells making up our defence system (immune system) attack parts of the body itself, such as the glands that keep the eyes and mouth moist, and glands in other parts of the body, altering their function. Symptoms in other organs, such as the lungs, joints or nervous system, may also occur.
