What causes an edema?

ANSWER

Things like a twisted ankle, a bee sting, or a skin infection will cause edema. In some cases, like an infection, this may be helpful. More fluid from your blood vessels puts more infection-fighting white blood cells in the swollen area. Edema can also come from other conditions or from when the balance of substances in your blood is off. Other causes include:

  • Low albumin
  • Allergic reactions
  • Obstruction of flow
  • A critical illness
  • Heart disease
  • Liver disease
  • Kidney disease
  • Pregnancy
  • Cerebral edema
  • Medications
