Immune disease is a general term used to describe a variety of diseases and disorders that affect the immune system. The immune system is a complex network of cells and organs that work together to protect the body from foreign invaders, such as bacteria, viruses, and other potentially harmful substances. When the immune system is weakened or not functioning properly, it can lead to an immune disease.
Types of Immune Diseases
There are a variety of different types of immune diseases, including autoimmune diseases, immunodeficiency diseases, and allergic diseases.
Autoimmune diseases are conditions in which the body’s immune system mistakenly attacks healthy cells, tissues, and organs. Examples of autoimmune diseases include lupus, rheumatoid arthritis, type 1 diabetes, and multiple sclerosis.
Immunodeficiency diseases occur when the immune system is weakened or not functioning properly. People with immunodeficiency are more likely to develop infections and illnesses. Examples of immunodeficiency diseases include HIV/AIDS, severe combined immunodeficiency syndrome (SCID), and primary immunodeficiency diseases.
Allergic diseases occur when the immune system overreacts to a harmless substance, such as pollen, dust, or certain foods. Examples of allergic diseases include asthma, hay fever, eczema, and food allergies.
Treatment of Immune Diseases
The treatment of immune diseases depends on the type and severity of the condition. Treatment may involve medication, lifestyle changes, and/or surgery. In some cases, a bone marrow or stem cell transplant may be necessary.
