Gastrointestinal flu with high fever requires a diet primarily consisting of soft, easy-to-digest foods. It is also necessary to consume more vegetables and fruits to supplement dietary fiber. Avoid cold, raw, and spicy, irritating foods. It is important to promptly use medications for treatment, such as those that clear heat and dampness, promote qi and release the exterior, dissipate heat and soothe the liver, suppress gastric acid secretion, and protect the gastric mucosa and intestines. For diarrhea, symptomatic antidiarrheal treatment should be used, and keep the abdomen warm. Rest more during this period and avoid excessive fatigue. (Please use medication under the guidance of a physician)
