Hiccups can have various causes, ranging in severity from 'life-threatening' to 'generally fatal'. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose hiccups, we could:
|Chronic Renal Insufficiency||90%||Confirm|
|Cardiac Ischemia||2%||Ruled out|
How often do you have hiccups?
Possible responses:→ Rarely / 'average' / Don't know
→ Regular minor episodes lasting several minutes
→ Regular major episodes lasting an hour or more
→ Current problem that won't stop
Hiccups usually last for only a few minutes, but can persist for days – or even months in rare cases. Although usually benign, they can sometimes be an indicator of underlying metabolic or infectious processes, including heart disease.
Persistent hiccups are a possible sign of kidney failure.
