Immune system diseases occur when the body’s immune system doesn’t work properly. There are many different types of immune system diseases, and they can range from mild to severe. Some common immune system diseases include allergies, autoimmune disorders, and cancer.
Immune system disorders
Immune system disorders can be broadly classified into two types: autoimmune diseases and immunodeficiency diseases. Autoimmune diseases occur when the body’s immune system attacks healthy cells, tissues, and organs. Immunodeficiency diseases occur when the body’s immune system is not able to properly fight off infection.
Types of Immune system disorders:
Low eosinophils: Low eosinophils levels in the blood can indicate an allergy or an autoimmune disease. A person’s immune system may not be functioning properly if they have an autoimmune disease. Autoimmune diseases can be difficult to diagnose because the symptoms can mimic other conditions.
Kawasaki syndrome: Kawasaki syndrome is an immune system disease that primarily affects young children. It is characterized by fever, rash, and swollen lymph nodes. In severe cases, it can lead to an inflammation of the heart and other organs. Treatment typically involves hospitalization and intravenous immunoglobulin.
Anginas: Anginas are caused by plaque in the arteries, which can restrict blood flow to the heart. This can cause chest pain, shortness of breath, and other symptoms. Treatment for anginas typically includes lifestyle changes, such as quitting smoking and eating a healthy diet, as well as medication to improve blood flow.
Leukocytosis: Leukocytosis is a medical condition characterized by an increase in the number of white blood cells in the blood. It is a sign of infection or inflammation.
Thyroiditis: Thyroiditis is an autoimmune disease that attacks the thyroid gland. The thyroid gland is a small, butterfly-shaped gland in the front of the neck. It makes thyroid hormone, which is important for metabolism, growth, and development.
High lymphocyte: A high level of lymphocytes is a feature of many autoimmune diseases, including lupus, rheumatoid arthritis, and type 1 diabetes. High lymphocyte counts also occur in some cancers.
Cytomegalovirus: Cytomegalovirus is a common immune system disease. It is caused by a virus that attacks the immune system. The virus is usually spread through contact with body fluids, such as blood or saliva.
Lumps under the armpit: Lumps under the armpit, also called lymph nodes, can be a sign of immune system diseases. If you have a lump or swelling in your lymph nodes, see your doctor.
Low defenses: Low defenses against infection can cause a person to get sick more often. A weakened immune system may also have more serious or life-threatening diseases, such as cancer, diabetes, heart disease, and HIV/AIDS.
