Hiccups in infants may be caused by improper feeding, indigestion or congenital heart disease, which can be treated by general therapy, medication and surgery. 1. Improper feeding: Newborn babies can cause hiccups if they are fed in an improper position or eat too fast or too quickly; parents can change the feeding position and burp after feeding to relieve the symptoms of hiccups, which can effectively relieve the symptoms of hiccups. 2. Indigestion: Indigestion can also cause hiccups in infants. Parents can massage the baby’s abdomen to promote gastrointestinal peristalsis and speed up digestion. When the symptoms are serious, the infant can be treated with probiotics under the guidance of the doctor. 3. congenital heart disease: congenital heart disease can lead to diaphragm compression, which causes non-stop hiccups, when the symptoms are serious, can be treated by surgical or interventional procedures to relieve the symptoms. There may be other reasons for the hiccups, so it is recommended to go to the hospital in time to improve the examination to clarify the cause of hiccups, and then give targeted treatment or therapy.
