Autoimmune diseases –

Autoimmune diseases are a group of disorders in which the immune system mistakenly attacks and damages the body’s own tissues. The immune system is designed to defend the body against harmful substances like viruses, bacteria, and other pathogens. However, in autoimmune diseases, the immune system fails to recognize certain tissues as “self,” leading to an immune response against normal cells and tissues.

There are many different autoimmune diseases, and they can affect virtually any part of the body. Some common autoimmune diseases include:

1. Rheumatoid arthritis:

A chronic inflammatory disorder that primarily affects the joints, causing pain, swelling, and stiffness.

Rheumatoid arthritis (RA) is a chronic autoimmune disease that primarily affects the joints, leading to inflammation, pain, swelling, and eventual joint damage. Unlike osteoarthritis, which is a degenerative joint disease, rheumatoid arthritis involves the immune system attacking the synovium, the lining of the membranes that surround the joints.

Here are key details about rheumatoid arthritis:

 1. Symptoms:

   Joint pain and swelling: Typically affects small joints, like those in the hands and feet, but can involve larger joints as well.
