Among the series of complications that occur in acute enteritis, the most common is water and electrolyte disorders. The increase in the number of diarrhea that occurs in acute enteritis leads to a large amount of water loss, which, in turn, leads to electrolyte imbalance, causing hyponatremia and hypokalemia, resulting in hypokalemia and hyponatremia. Repeated hypokalemia and hyponatremia can easily lead to hypokalemic intestinal paralysis, hypotonic encephalopathy, and in some severe cases can lead to coma. Therefore, acute enteritis with electrolyte disorders and water loss requires active rehydration, vitamin and trace element supplementation and other symptomatic treatments. Secondly, if acute enteritis repeatedly irritates the intestinal mucosa, it can cause congestion and edema of the intestinal mucosa, and blood in the stool can occur. Most of the blood in the stool is fresh blood stool, the amount is relatively small, some can appear wash water-like blood stool, most of the results of intestinal inflammation caused by mucosal rupture.
