Intestinal spasm and functional abdominal pain are not the same thing, intestinal spasm can cause functional abdominal pain, but in addition to this, phytoneurological dysfunction can also cause functional abdominal pain. 1. Intestinal spasm: when the smooth muscle of the intestinal wall produces paroxysmal strong contraction due to dietary impurity, cold stimulation and other reasons, it can lead to acute abdominal pain. However, when examined, there is usually no organic lesion in the abdomen. This belongs to functional abdominal pain. 2. Phytoneurological dysfunction: If the phytoneurological dysfunction is caused by prolonged staying up late, excessive stress or tension, it will cause abnormal function of the internal organs in the abdominal cavity, such as abnormal contraction of the gallbladder, uterine spasms and so on, which will lead to functional abdominal pain in the abdomen. Functional abdominal pain is usually not accompanied by substantial lesions. Although functional abdominal pain is usually not accompanied by organic changes, but it will also bring pain to the patient, it is recommended that the patient should go to the hospital in time for treatment.
