Small bowel spasms have symptoms such as abdominal pain, abdominal distension, nausea and vomiting. 1. Abdominal pain: manifested as paroxysmal, intermittent colic, with the periumbilical area obvious. When the pain attacks, there may be painful expression, pale face, cold hands and feet, etc., because it is difficult to bear the pain often into a curled-up shape. 2. Abdominal distension: it may occur before or after abdominal pain, and it is mostly caused by abnormal intestinal peristalsis due to intestinal spasm. 3. Nausea and vomiting: the attack of intestinal spasm can lead to transient intestinal obstruction, which induces nausea, vomiting, and stopping anal defecation and other symptoms. The symptoms usually disappear after the resumption of gas or defecation. For the diagnosis of small bowel spasms, it is easy to miss or misdiagnose the disease simply by relying on the symptoms. It is recommended to consult a doctor in time to clarify the diagnosis by combining blood tests and abdominal radiographs with the diagnosis of small bowel spasm.
