What's with the hiccups?

Hiccups are caused by spasm of the diaphragm, inflammation or stimulation of other organs around the diaphragm. Patients with gastrointestinal diseases, such as gastritis and flatulence, show hiccups. This is due to excessive gas in the stomach, resulting in retrograde. Drugs that promote gastrointestinal motility can be used to promote digestion and reduce gas accumulation. Therefore, proper walking after meals can promote gastrointestinal digestion.
