What's with the hiccups after coughing?

Hiccup generally refers to hiccup, hiccup after cough is mainly caused by diaphragm spasm.

The sensory fibers of phrenic nerve are distributed in pericardium, pleura and other parts of human body, and can sense external stimulation. Usually, patients with severe cough can repeatedly relax and contract their lungs, which may stimulate the sensory fibers of phrenic nerve located in pleura, resulting in current signals generated by motor fibers. When diaphragm receives current signals, it can stimulate diaphragm to rise repeatedly and cause frequent hiccups.

At this time, patients can relax diaphragm by holding breath, drinking hot water, etc., and massage and hot compress chest and abdomen appropriately.
