病因病机：
主要病因是冲任不固，经血失于制约而致血量多。
常见的分型有气虚、血热和血瘀。
①气虚 素体虚弱，或饮食失节，劳倦过度，大病久病，损伤脾气，中气不足，冲任不固，血失统摄，遂致经行量多。
②血热 素体阳盛，或恣食辛燥，感受热邪，七情过极，郁而化热，热扰冲任，迫血妄行，遂致经行量多。
③血瘀 素性抑郁，或忿怒过度。气滞而致血瘀，或经期产后余血未尽，感受外邪，或不禁房事，瘀血内停，瘀阻冲任，血不归经，遂致经行量多。
血崩亦称崩中、暴崩，指妇女不在经期而突然阴道大量出血的急性病证。本病病因颇多，有因劳伤过度，气虚下陷，统摄无权所致；有因暴怒伤肝，肝不藏血，经血妄行而发为血崩；亦可素体热盛，复感热邪或恣食辛燥之品，积热化火，热迫血行而发病；另有经期产后，余血未尽，或因外感，夹内伤，瘀血内阻。恶血不去，新血不得归经，造成崩中。现代医学中的功能性子宫出血之重症者。
可分为下列三型：
1.气虚，暴崩下血，色淡质薄，面色晄白或虚浮，困倦乏力，动则气短，脉细弱或芤。舌体胖嫩有齿印，苔薄润或腻。
2.血热，突然血出如崩，血色深红，头晕面赤，烦躁口渴，脉滑数或弦数，苔黄。
3.血瘀，血出淋漓不断，猝然其势若崩，夹有瘀块，血色紫暗，小腹疼痛拒按，脉沉涩或沉紧，舌质暗红，舌尖边时见瘀点。
