SLE Problems

Over time SLE can lead to:

  • Kidney disease—Long term swelling can harm structures in the kidney. This keeps them from working the right way.
  • Heart disorders—Swelling can affect tissue of the blood vessels, heart, and heart valves. This can lead to heart problems, such as high blood pressure , heart failure , heart attack , or stroke .
  • Breathing problems—Chronic swelling can harm and scar the tissue of the lungs or the lining around them. This makes it hard to get oxygen into the blood. It can cause chest pain or a hard time breathing.
  • Brain disorders—Swelling of nerves can lead to headaches , mood problems, cognitive impairment , psychosis , and seizures .
  • Blood disorders—Swelling can also lead to damage of blood cells and anemia (low red blood cells), thrombocytopenia , leukopenia, or an greater risk of blood clots (which can lead to heart attack or stroke).

SLE may also cause problems during pregnancy. There may be a flare-up of symptoms, kidney problems, or a type of high blood pressure called pre-eclampsia . There is also a greater risk of premature birth , stillbirth , miscarriage , or growth problems with the baby in the womb.
