What causes a diver to get hiccups?

Question

I've gone diving for the past two weekends, and I keep getting hiccups that won't go away! Both times, I had to call my dive. They began when I surfaced. Am I doing something subconsciously that is causing this?

Answer 1

nether answer is correct i am a scuba instructor (PADI) it does have to do with presure, but it is the preasure change, you might be comming up to fast and the expanding air is streaching your diaphram a bit causing hiccups

it could also just be that you are swallowing air down wrong pipe

Answer 2

the lack of air in its lungs

Answer 3

you are prolly rising for the surface to quickly when you dive more then 10m down and come up you have to wait to surface for about 5mins at a depth of 6-5m, the pressure on your lungs causes the hiccups and CO2.

Answer 4

You are holding your breath instead of exhaling it under water.   Try exhaling just after you enter the water; you should not come to the surface and suddenly expel all of your air.  You need to let it out sooner!  You are sending your diaphragm into hiccups by holding the air in too long.
