Children and adults are prone to gastrointestinal spasms, and triggers include cold, inflammation, or gastrointestinal dysfunction. The less developed central nervous function and immature intestinal function in children can lead to gastrointestinal cramps in childhood. Some children are allergic to milk, combined with respiratory infections, cold stomach and overeating, large amounts of cold food or excessive sugar intake can lead to intestinal gas accumulation, indigestion, parasites, toxin stimulation and thus cause intestinal spasms in young children, when children are prone to colic. The child is prone to crying and restlessness, accompanied by vomiting, tumbling and flushed cheeks. Due to abdominal distension and tension, the child’s legs are shown to be stretched upward. The triggering factors of adult intestinal spasm, including overeating, spicy and irritating food, indigestion or abdominal cold can trigger intestinal spasm in adults, which is easily manifested as colic, a paroxysmal abdominal pain caused by strong contraction of the smooth muscle of the intestine. By drinking more hot water to keep the abdomen warm, hot water bags can relieve symptoms.
