Symptoms of fever due to food accumulation usually include loss of appetite and fever, etc. The treatment usually includes oral solution for food accumulation and adjustment of diet structure. Usually, accumulation of food refers to a series of symptoms caused by the patient’s abnormal digestive function, resulting in food not being digested in time, including abdominal distension, abdominal pain and loss of appetite. The development of this disease may lead to prolonged fever in patients, which is usually characterized by low-grade fever. The main measure for treating food retention in general is to take medicines to strengthen the spleen and open the stomach (by strengthening the spleen to enhance appetite) to aid digestion under the guidance of a doctor, such as Huaji Oral Liquid. In terms of diet, patients should pay attention to adjusting the diet structure, eating more vitamin-rich vegetables, drinking more water and exercising more, etc. For patients with fever due to accumulation of food, it is recommended that treatment be carried out under the guidance of a doctor to avoid blind use of medication, which may cause adverse consequences.
