Sunlight, stress, pregnancy and certain medications can cause lupus to flare up, explains About.com. Flare-ups are, for the most part, unpredictable and can occur at any time.
An individual who has lupus needs to avoid stressful situations and should practice relaxation techniques to reduce the possibility of lupus rash flare-ups, About.com says. While lupus rash is one symptom of the disease, other symptoms include weakness, fatigue, body aches, abdominal pain, nausea and vomiting. An individual can also experience weight loss, hair loss, blood in the urine, shortness of breath and fever.
The best treatments for lupus include a healthy lifestyle and plenty of rest, advises About.com. Those with this disease should eat healthy foods and get plenty of exercise. Because sunlight can trigger flare-ups, an individual who has lupus needs to avoid staying out in the sun. Although flare-ups do occur, an individual should always see a doctor.
Lupus is an immune system disorder in which the body attacks itself, treating the healthy tissues like a foreign infection, WebMD explains. One of the first signs is joint pain. The lupus or butterfly rash appears on the face, turning the skin flaky and scaly. The rash also appears on the neck and arms in a purplish color.
