Vertical strips of hard things in the abdomen are usually feces, but we can not rule out the possibility of suffering from intestinal obstruction and intestinal tumors. 1. Feces: for people with constipation who have less abdominal fat, if you find a vertical strip of hard things in the abdomen, it is usually feces in the colon, and some people will also have abdominal pain and other symptoms. 2. Intestinal obstruction: Intestinal obstruction is mainly caused by intestinal adhesions, tumors, intestinal inflammation, etc. Patients will have abdominal pain, constipation, vomiting and other symptoms, and they can feel the hard vertical stripes in the abdomen. 3. Intestinal tumors: vertical hard things may also be intestinal tumors, which are benign and malignant tumors occurring in the small intestine and large intestine. If the tumor volume is small, generally will not appear clinical manifestations, if the tumor volume is large, not only will appear compression symptoms, the patient will also feel the vertical strip of hard things in the abdomen. If you find a hard vertical strip in your abdomen, you should go to the hospital for examination after excluding constipation, and follow the doctor’s instructions for treatment after a clear diagnosis.
