The causes of intestinal nodules are as follows: 1, usually due to the frequent consumption of acid, spicy, greasy, easy to fire and other irritating foods, resulting in frequent abnormal stimulation of the intestinal mucosa, resulting in nodular hyperplasia; 2, it is possible that food often stimulates the intestinal mucosa, resulting in chronic inflammation of the intestine, long-term inflammatory stimulation is also likely to lead to nodular hyperplasia; 3, some patients often have constipation, which may also lead to intestinal nodules; 4, some intestinal multiple nodules are due to physical problems or family inheritance. To diagnose intestinal nodules, a colonoscopy must be done to determine if they are small nodules, they can be given directly for removal, and if they are large nodules, they must be treated surgically.
