In medicine ischemia also spelled as ischaemia or ischæmia (/ɪˈskiːmɪə/) is a restriction in blood supply to tissues causing a shortage of oxygen and glucose needed for cellular metabolism (to keep tissue alive). Ischemia is generally caused by problems with blood vessels with resultant damage to or dysfunction of tissue. It also means local anemia in a given part of a body sometimes resulting from congestion (such as vasoconstriction thrombosis or embolism).
