血糖浓度是调节胰素分泌的最重要因素。在持续高血糖刺激下,胰岛素的分泌可分为以下四个阶段:第一阶段:血糖升高后,胰凫素分泌量立即增加,5min内可增加10倍,所释放的激素主要来源于胰岛B细胞内贮藏的激素。第二阶段:5~15min内,胰岛素的分泌量逐渐下降。第三阶段:15min后,胰岛素的分泌量再次增多,在2~3h达到高峰,并持续较长的时间,分泌速率也远大于第一阶段。这主要是胰凫素基因大量表达的结果。第四阶段:倘若高血糖持续一周左右,胰凫素的分泌量还会进一步增加,这是由于长时间的高血糖刺激胰岛B细胞增殖所致。请根据以上资料回答下列相关问题:

若某人患有自身免疫病,产生的抗体破坏了靶细胞表面的胰岛素受体,则与正常人相比,病人的胰岛素分泌量将()。
