Recognizable Symptoms Of Lupus
Problems Breathing

If you are suddenly experiencing problems breathing, this may be a sign of lupus. Lupus affects the pulmonary system by causing inflammation of the lungs and blood vessels, which can restrict oxygen flow to the rest of the body. Breathing difficulty may be one reason for unexplained fatigue. You may also notice it feels harder to breathe due to the increased pressure on the diaphragm. Some people with lupus experience pleuritic chest pain when they try to breathe. Lupus can also shrink the lungs over time.
