Theory 78/Hiccups/Ratio lens
Susceptibility Is a Volume Ratio
The claim
Hiccup susceptibility is set by the ratio of stomach volume to lung capacity, which is why they follow large meals and carbonated drinks.
01Mechanism
A distended stomach irritates the diaphragm; the ratio determines how much mechanical trigger reaches the reflex.
02Prediction
Susceptibility should track the ratio.
03Refutation
Susceptibility tracking meal size would remove lung capacity.
