Bowel spasm generally refers to intestinal spasms, the cause of which is still unclear and may be related to factors such as improper diet and accumulation of gas in the gastrointestinal tract. Intestinal spasm is caused by paroxysmal strong contraction of the smooth muscle of the intestinal wall. The cause of the disease is still unclear, but it may be related to the patient’s improper diet, such as the intake of allergies, spicy and irritating foods. Some patients with intestinal cramps are due to gas accumulation in the gastrointestinal tract, intestinal dynamics disorders, gastrointestinal hormone abnormalities and other factors. For infants and young children with intestinal spasms, it should also be considered that the immaturity of the nervous system and the high sensitivity to external stimuli have a certain relationship. In addition to the above causes, intussusception, intestinal duplication malformation, intestinal malrotation, etc. can cause secondary intestinal spasm, and attention should be paid to differentiate. It is recommended that people diagnosed with intestinal spasms actively cooperate with doctors for treatment, so as to relieve the discomfort caused by the disease and improve the quality of life.
