Evolution has made an amazing gift for women - a strong immune system so that they can continue childbirth.But why, then, in 80% of cases, autoimmune diseases affect women, mainly at a young age? Rheumatoid arthritis, systemic lupus erythematosus, systemic scleroderma, Sjögren's syndrome, and many others. This is definitely a challenge for science! Carlo Selmi, an immunologist, applying a gender approach to the treatment of his patients and research, explains in detail how the female immune system differs from the male one, as well as what conclusions should be drawn from this to make the treatment of diseases much more effective. In addition, the author dwells in detail on such important topics for health as nutrition, physical education, vitamins and medicines.
