What Is Lupus?

Systemic Lupus Erythematosus, also called Lupus, is an autoimmune condition where the body starts attacking its own cells. It can involve multiple systems like the skin, kidney, joints, etc.

What Can Trigger It?

Some people are genetically susceptible to Lupus, and the symptoms can be triggered by a number of infections, some drugs, and at times, even sunlight

When Symptoms Come and Go

Its signs and symptoms can be transient, in the form of flares. Rashes and joint pain are the most common symptoms, whereas brain and kidney related problems are the most serious

The Classic Rash

The affected person may become  highly sensitive to light, and a butterfly-shaped rash (called the malar rash)  may be seen on the skin

Other Skin and Nail Clues

Oral ulcers, thinning of hair/hair loss, and splinter haemorrhages are also seen in people with this autoimmune disease, along with thrombotic manifestations

Blood Cell Reductions

Reduced blood haemoglobin levels  lead to anaemia in patients, and other necessary blood cells like white blood cells and platelets may also be reduced

When the Brain Is Involved

Neurological manifestations of SLE include delirium, psychosis, and even seizures. Some may experience mood disorders and headaches as well

Impact on the Heart

The heart is also affected, and  there can be inflammation of the  cardiac wall, disease of the arteries  that provide blood supply to the heart, and also pulmonary hypertension

Digestive System Symptoms

Non-specific gastrointestinal symptoms like nausea, abdominal pain, diarrhoea and, in severe cases, perforation, are also observed in those with SLE

Diagnosis and Prevention

SLE autoantibodies are necessary for diagnosis, like anti-nuclear antibodies and anti-double-stranded DNA antibodies. Avoid triggers like ultraviolet light and smoking
