Why do you keep hiccupping?

Hiccups are mostly caused by indigestion or diaphragmatic spasm. Due to digestive disorders, excessive gas is produced in the stomach, causing hiccups symptoms. It may also be caused by diaphragm spasm caused by cold food stimulation. Persistent hiccups also require gastroscopy to rule out gastritis, digestive tract tumors, peptic ulcers and other gastrointestinal diseases. In addition, if you are in a state of mental stress for a long time, it will affect the digestion of food on the one hand, and cause the diaphragm to show spasmodic contraction on the other hand, causing long-term hiccups. A few nervous system diseases, such as cerebral hemorrhage, cerebral infarction, encephalitis and other damage to the diaphragmatic nerve reflex cause hiccups.
