In some cases, your immune system makes the mistake of viewing a healthy body cell as a potential pathogen. The defense mechanism must destroy it to curb infection. Basically, your immune system is doing its regular job. The only difference is instead of protecting the healthy cells, it starts attacking them thinking they are microbial invasions.
The complete battalion of antibodies starts launching attacks on the healthy host. This flaw might look inconsequential at the surface. But deep down, it lays the foundation of autoimmunity. This misguided attack happens when the immune system fails to differentiate between “self” and “non-self” cells. Our immune system is largely dispersed throughout our body. As a result, autoimmunity has no specific location.
Such disorders, which occur because of auto-immunity, are Autoimmune Diseases. Autoimmune diseases could affect one or more than one site. Be it your central nervous system or your gastrointestinal tract. Be it your skin or the blood vessels circulating under it. Any part/s of your body can be targeted by autoimmunity.
