Both gastrointestinal accumulation and gastrointestinal retention are the accumulation of food in the stomach and intestines, which cannot be excreted smoothly, but the causes of gastrointestinal accumulation and gastrointestinal retention are different, and their treatments are different. 1. Different causes: Gastrointestinal accumulation is mainly due to indigestion, overeating, gastroenteritis, intestinal dysfunction, resulting in intestinal peristalsis and obstruction of gastrointestinal content excretion, which leads to gastrointestinal accumulation. And gastrointestinal retention is mainly due to intestinal tumors, intestinal obstruction, intestinal strangulation, etc., which cause gastrointestinal retention by obstructing the intestinal tract and leading to intestinal emptying obstruction. 2. Different treatment modes: gastrointestinal retention is mainly treated by taking gastric stimulants or drugs that regulate intestinal flora to promote intestinal peristalsis and improve gastrointestinal retention. However, gastrointestinal retention is mainly treated by surgery to solve the obstruction and blockage of the intestinal tract and change the gastrointestinal retention.
