Lupus is a chronic autoimmune disease in which the immune system attacks healthy cells and tissues, leading to inflammation and damage in various parts of the body. Symptoms of lupus can vary widely and may include joint pain, skin rashes, fatigue, and organ damage. Treatment typically involves a combination of medication, lifestyle changes, and regular monitoring by healthcare providers. Researchers are actively studying the underlying causes of lupus, as well as developing new treatments and improving the quality of life for those living with the disease.
