Hiccups, commonly known as hiccups, usually do not cause heart discomfort, and may be related to diaphragmatic spasm, pericarditis, gastritis, etc. 1. Diaphragmatic spasm: This condition usually lasts for a relatively short time, and is commonly seen in some people after a meal, after drinking alcohol, or after being stimulated by certain stimuli, which causes diaphragmatic spasm and thus the appearance of hiccups. 2. Pericarditis: Inflammation of the pericardium due to viral or bacterial infection of the pericardium can cause pericardial inflammation, which may irritate the phrenic nerve and lead to hiccups. 3. Gastritis: Due to insufficient gastric motility or overburdening of the stomach after eating, gastric peristalsis is slow, and gastrointestinal gases accumulate, which may irritate the diaphragm and lead to hiccups. If you are experiencing hiccups with other discomforts, it is recommended that you consult a doctor for further examination, to identify the cause and to provide targeted treatment or therapy with the help of your doctor.
