The symptoms of abdominal pain in patients with intestinal obstruction are mainly related to the severity of the disease. In the case of simple intestinal obstruction it can be treated by removing the cause, gastrointestinal decompression, fasting, and nutritional support. As the pressure in the abdominal cavity decreases, it is possible to obtain relief of symptoms. For paralytic intestinal obstruction caused by hypokalemia, electrolyte balance can be maintained, potassium supplementation can be handled in time, and the symptoms are likely to disappear after potassium ions are restored. However, for strangulated intestinal obstruction, the condition is more critical, at this time, the abdominal pain is persistent severe pain, intolerable, and even intestinal necrosis, intestinal perforation and other possibilities, at this time, the only way to achieve the purpose of symptomatic relief is to be treated by surgery.
