What are the causes of intestinal obstruction? Generally, in clinical practice, the causes and inducements of intestinal obstructions are mainly divided into the following aspects: Firstly, there are extraintestinal disorders, such as some space-occupying lesions in the abdominal cavity compressing the intestinal tube, causing narrowing of the intestinal lumen and thus obstruction. Additionally, there are diseases of the intestines themselves. Some severe intestinal diseases or tumorous conditions, or ischemic diseases of the intestines themselves, can all potentially lead to intestinal obstruction. If the symptoms of intestinal obstruction are typical, hospital treatment and possibly surgery may be necessary. Furthermore, some motility factors within the abdominal cavity can also cause intestinal obstruction, such as a reduction in the motility of the intestines or paralysis and expansion of the intestines due to electrolyte disturbances, leading to symptoms of intestinal obstruction.
