Abdominal cramps may be caused by intestinal spasm, intestinal obstruction, kidney stones and so on. 1. Intestinal spasm: due to cold stomach, eating too cold food, etc., cold stimulation can easily lead to intestinal spasm, which will lead to abdominal cramps. 2. Intestinal obstruction: the intestines have the function of transportation, which can make the food go downward and eventually form feces to be discharged out of the body. If the intestines form obstruction in the process of discharging, the food or feces can’t go through, and the intestines will be frequently and violently peristaltic, which will lead to abdominal colic, accompanied by nausea and vomiting phenomenon. 3. Kidney stones: If you suffer from kidney stones, colic may occur when the stones are migrating, and the pain may radiate to the lower abdomen, perineum, inner thighs and other parts of the body, resulting in abdominal colic. If colic occurs, it is recommended to consult a doctor for examination, according to the specific situation, follow the doctor’s advice, and actively cooperate with the treatment, so as to avoid aggravation of the condition and delay of treatment.
