Multiple chemical sensitivities (MCS) is a chronic condition of irritation and inflammation of sensory organs, gastrointestinal distress, fatigue, and compromised neurological function, including learning and memory deficits, unpleasant smells, tingling of nerves, and sensory discomfort. Victims report these symptoms after exposure to unfamiliar chemicals. Some studies have linked MCS to immune system dysregulation. MCS is believed to be a disease that spreads between various target organs, and is caused by sensitization to chemicals with very different structures. MCS is often attributed to free radical production and stress, which indirectly cause spreading because of damage to the immune system.
多重化学物质敏感症（MCS）是一种慢性病，表现为感觉器官的刺激与炎症、胃肠道不适、疲劳以及神经功能受损，包括学习和记忆缺陷、嗅觉不适、神经刺痛和感觉不适。受害者在接触不熟悉的化学物质后会出现这些症状。一些研究已将多重化学物质敏感症与免疫系统失调联系起来。人们认为多重化学物质敏感症是一种在各个靶器官之间传播的疾病，由对结构差异很大的化学物质产生致敏作用所致。多重化学物质敏感症常归因于自由基生成和压力，它们因损害免疫系统而间接导致症状蔓延。
