Pain around the navel is usually seen in diseases within the small intestine and may be caused by the following: 1. Enteritis: usually caused by bacterial or viral infections, but can also be caused by certain drugs. The typical manifestation is pain around the navel, which can also be accompanied by symptoms of bloating, nausea, vomiting, and even diarrhea. For patients who are usually in good health, mild acute enteritis does not have a significant impact on life and health status. However, for the elderly, young, sick and disabled, acute enteritis can usually cause severe dehydration, even shock and other life-threatening symptoms; 2. intestinal obstruction: i.e., the passage of the contents of the intestine is blocked, and patients usually experience paroxysmal peribulbar colic, usually accompanied by nausea, vomiting, abdominal distension, and even anal defecation and exhaustion stop; 3. mesenteric lymphadenitis: mostly seen in adolescents and children, usually before the appearance of peribulbar pain A week or so before the appearance of peribulbar pain, there may be a history of upper respiratory tract infection and respiratory manifestations such as fever and enlarged tonsils, but if it is between two abdominal pains, there may be no abdominal symptoms; 4. Intestinal tuberculosis: intermittent episodes of abdominal pain accompanied by abdominal rumbling, i.e., stomach grumbling, may also occur, but such manifestations are not specific for intestinal tuberculosis. Patients with intestinal tuberculosis are mostly accompanied by symptoms of tuberculosis toxicity. If there is irregular low fever, night sweats or family history of tuberculosis, the presence of intestinal tuberculosis may be considered; 5. Functional gastrointestinal disease: If relevant examinations are performed, peribulbar pain caused by functional diseases may be considered if organic diseases are excluded.
