A butterfly rash is a rash that takes the shape of a butterfly. Known more formally as a ‘malar rash’, a butterfly rash is most commonly associated with the autoimmune disease lupus, though it can also be present in other conditions and particularly other autoimmune conditions.

What Is Lupus?
Lupus is an autoimmune condition meaning that it is caused by the body’s own immune system. In lupus the immune system begins to attack the cells of the body and this results in a range of other systems. Being able to tell the symptoms is a good way to identify whether lupus might in fact be the cause of a rash.

Unfortunately lupus is a very difficult condition to diagnose and this is because it belongs to the group of diseases unofficially known as ‘the great imitators’. These are the diseases that it has been noted mimic other conditions in their symptoms and vary greatly making it very easy for misdiagnosis. This means that many people go untreated with lupus for years.
However other signs of lupus to look out for include:
-- Swelling and arthritis in the joints
-- General lethargy and low energy
-- Poor circulation and cold extremities
-- Lack of appetite
-- Photosensitivity

Lifestyle
Sun exposure can trigger or worsen malar rashes, so you should always wear a hat with a wide brim and sunscreen with at least SPF 55 when in the sun. Fatigue is another common symptom of lupus and can contribute to other symptoms. If you get enough rest, you are likely to have fewer flare-ups and recover from them faster than lupus patients who need more sleep. Regular exercise and a healthful diet of whole grains, fruits, vegetables and lean protein can also help you manage your symptoms.
