ComplicationsBy Mayo Clinic staff
For most people, symptoms improve within a month, leaving no lasting problems. Recurrences are fairly common, however.
Complications associated with Henoch-Schonlein purpura include:
- Kidney damage. The most serious complication of Henoch-Schonlein purpura is kidney damage. Occasionally the damage is severe enough that dialysis or a kidney transplant may be needed.
- Bowel obstruction. In rare cases, Henoch-Schonlein purpura can cause intussusception — a condition in which a section of the bowel folds into itself like a telescope, which prevents matter from moving through the bowel.
