What is Hiccups?
Hiccups are involuntary contractions of the diaphragm, causing the characteristic sound as air is suddenly drawn in. They're usually harmless and triggered by things like eating too quickly, carbonated drinks, alcohol, or sudden temperature changes, typically resolving on their own within a few minutes.
While most hiccup episodes are brief and not a cause for concern, persistent hiccups lasting more than 48 hours are less common and worth medical assessment, as they can occasionally indicate an underlying condition.
02 · Understand
Clinical context
Most home remedies work by interrupting the diaphragm's rhythm
Many traditional hiccup remedies — like holding your breath or drinking water quickly — work by disrupting the nerve signal causing the diaphragm spasm, which is why a range of different techniques can each be effective for different people.
