Andrea asked the Naked Scientists:
   
Why do fizzy drinks give me the hiccups? - even if I don't use a straw and let the drink go practically flat I still get the hiccups.

What do you think?

Hiccups are a diaphragmatic spasm; some component of the respiratory control centre in the brainstem initates the strange pattern of nerve activity that triggers this. I think it can also be caused by raised CO2. Moreoever, when this neurological circuitry is damaged by things like strokes, trauma, tumours or some drugs, hiccupping can be a consequence.

I wouldn't for one minute suggest that you have any of the above, but it's possible that some part of your pharynx or airway is more sensitive to CO2 and this could be confusing the wiring in the brainstem. This is just speculation, however. I've not heard from anyone else who complains of cola-induced hiccups!

I get curry induced hiccups, or, I should really say I used to in the UK. I haven't been served any curry dishes in the US that are hot enough to trigger the effect.
