One new disorder that is very likely a result of GMO foods is called systemic inflammatory response syndrome or SIRS for short. Is it ironic that the medical term SIRS was coined at the same time that GMO foods were being introduced into the food market in the United States? You decide. Medscape and Wikipedia state that SIRS was identified in 1992 as an inflammatory state affecting the whole body, a response of the immune system to an infectious or noninfectious insult.
