The causes of abdominal cramps include emotional excitement, abdominal cold, improper diet, gastrointestinal ulcers, intestinal inflammation, etc. There are more than five causes, and it is recommended to go to the hospital to find out the cause. 1. Emotional excitement can lead to sympathetic nerve excitation, causing smooth muscle contraction of the gastrointestinal tract, which is manifested as abdominal cramps. 2. A cold abdomen will stimulate the smooth muscle of the gastrointestinal tract to contract, resulting in abdominal cramps. 3. Improper diet, such as spicy and irritating food, drinking alcohol, etc., can also stimulate the mucous membrane of the gastrointestinal tract to spasm. 4. When the gastrointestinal tract is ulcerated, the damaged gastrointestinal tract mucosa stimulates the smooth muscle and causes abdominal cramps. 5. Inflammation of the intestinal tract continues to stimulate the mucosa can also cause strong contraction of smooth muscle, resulting in abdominal cramps. Therefore, when abdominal cramps occur, it is recommended to go to the hospital in a timely manner to clarify the cause of the disease and standardize the treatment of the cause under the guidance of the doctor.
