What is Lupus?

Systemic Lupus Erythematosus

Quick Answer

Lupus is a chronic autoimmune disease where the body's immune system mistakenly attacks healthy tissues. This can lead to inflammation and damage in various parts of the body, including the skin, joints, and organs.

Overview

Lupus is a complex disease that affects many parts of the body. It occurs when the immune system, which usually protects us from infections, becomes overactive and starts attacking healthy tissues. This can cause symptoms like joint pain, skin rashes, and fatigue, making daily activities challenging for those affected. The exact cause of lupus is not fully understood, but it is believed to involve a combination of genetic, environmental, and hormonal factors. For instance, some people may develop lupus after exposure to certain medications or infections. A common example is a butterfly-shaped rash that appears on the face, which is a hallmark sign of the disease and can be triggered by sunlight. Understanding lupus is important because it can lead to serious health complications if left untreated. It can affect organs such as the kidneys, heart, and lungs, and may require long-term management. Awareness and early diagnosis can help improve the quality of life for those living with lupus.
