Babies often have poor appetite after fever due to disease factors or impaired spleen and stomach functions, which can be adjusted in the following ways: First, the diet should be light and easy to digest, mainly drinking porridge, eating rice flour and other easily digestible food, avoiding greasy and stimulating food to increase the burden on the gastrointestinal tract, which is not conducive to the recovery of appetite. Second, you can take oral medication to help digestion to adjust appetite, such as spleen-awakening and stomach-opening granules, oral liquid for stomach and appetite or large hawthorn granules. Third, the baby is prone to micronutrient deficiency in the late stage of the disease, which may also lead to poor appetite. Oral zinc gluconate oral solution can be given for 10-15 days or about 1 month to supplement zinc elements, which is beneficial to the recovery of appetite. Parents can adjust the baby’s appetite by using acupressure points in Chinese medicine, which is beneficial to the recovery of appetite.
