近年来，电子烟市场如雨后春笋般涌现，成为许多人改善吸烟习惯或戒烟的选择，随着PG（乙酰联环戊烷）烟弹的普及，越来越多的人开始出现PG过敏反应，PG过敏不仅是一种简单的皮肤刺激，更可能引发严重的呼吸道和肺部问题，什么是PG过敏？为什么电子烟会成为过敏的诱因？PG过敏对健康到底有多大的危害？这些问题值得我们深入探讨。

PG过敏的机制：PG如何刺激人体？

PG过敏是一种化学过敏反应，主要由对PG及其代谢产物的过敏引起，PG是一种高度合成的化学物质，广泛存在于含尼古丁的烟弹中，PG的主要成分包括二甲基丙烯酰胺（DMAC）、乙酰胆碱利钠（AT1R）、乙酰胆碱利卡因（AT2R）等，这些化学物质在人体内代谢后,会刺激呼吸道中的过敏反应。

1. DMAC的刺激作用
   DMAC是一种高度水溶性的化学物质，能够通过呼吸道黏膜渗透进入体内，DMAC刺激呼吸道中的肥大细胞、嗜碱性粒细胞等免疫细胞,导致过敏反应。

2. AT1R和AT2R的代谢产物
   PG在人体内代谢后会产生AT1R和AT2R代谢物，这些代谢物可以直接刺激呼吸道中的过敏细胞，导致炎症反应和气道 narrow down。

3. 呼吸道黏膜的直接刺激
   PG不仅通过代谢物刺激呼吸道黏膜，还可能直接通过其化学结构刺激黏膜细胞,导致细胞死亡和上皮层损伤。

PG过敏的临床表现：症状是如何出现的？

PG过敏的症状通常在接触PG烟弹后逐渐出现，程度因人而异,以下是常见的PG过敏症状：

1. 轻度过敏反应
