The common reasons for hardness around the navel may be the following: First, the patient has a tumor lesion in the abdominal cavity, and as the tumor increases in size and presses on the intestinal canal, a hard mass can be felt around the navel during body check. At this time, it is necessary to improve abdominal CT examination as soon as possible to clarify the source of the tumor lesion, perform surgery to remove the tumor, release the local intestinal tube compression and improve the symptoms of hardness around the navel. Secondly, due to the weakening of gastrointestinal function, a large amount of stool can block the intestinal canal around the navel in elderly patients, resulting in the symptoms of local hardness. Oral lactulose, Benadryl tea can be given to promote the excretion of intestinal contents, if necessary, give low-pressure enema treatment. After the intestinal contents are completely excreted, the symptoms of hardness around the navel can be gradually relieved.
