Newborn hiccups are called neonatal hiccups in medicine, which are mostly caused by physiological factors, but may also be caused by meningitis, epilepsy and other diseases. 1. Physiological factors: Due to the imperfect neural development of newborns, their nerve reflexes are not yet coordinated, and they are prone to diaphragmatic spasms. In addition, the temperature of food, eating too fast, cold air inhalation, and changes in temperature can also induce neonatal hiccups. 2. Pathological factors: such as meningitis, epilepsy, intracranial congenital tumors, intracranial hemorrhage, diaphragmatic disease, etc., the patient is more often accompanied by other discomforts, such as meningitis, the child can also appear vomiting, lethargy, irritability, irritability, depression, fever and other discomforts. If a newborn baby has hiccups that do not go away or are accompanied by other discomforts, it is important to consult a doctor to find out the cause of the hiccups, and then follow the doctor’s instructions for appropriate treatment if necessary.
