Immune disorders

Immune disorders occur when the body's immune system, which normally fights off infections, malfunctions—either attacking the body's own tissues (autoimmune diseases like rheumatoid arthritis) or failing to defend against harmful pathogens (immunodeficiency). These conditions can lead to chronic inflammation, tissue damage, recurrent infections, or overactive immune responses. Causes may include genetics, infections, or environmental factors. Treatment often involves managing symptoms, suppressing harmful immune activity, or boosting immune function, depending on the disorder. Proper diagnosis and medical care are essential to control symptoms and prevent complications.
