我的肚子有时候会发出奇怪的声音

Hiccups happen when your diaphragm — the muscle below your lungs — contracts suddenly.
This quick jerk pulls air into your throat and slams your vocal cords shut with a 'hic' sound.
Eating too fast, drinking fizzy drinks, or feeling nervous can all trigger hiccups.
Most hiccups last only a few minutes and go away without any treatment needed.
Holding your breath or sipping cold water may help calm the diaphragm again.
Babies hiccup often because their nervous systems are still learning to control breathing.
Doctors rarely worry about short hiccups, but long ones might need gentle tests.
You can talk, walk, or laugh while hiccuping — it won’t hurt your body or voice.
Some people try sugar on the tongue or gentle neck pressure to stop stubborn hiccups.
Even astronauts get hiccups in space — gravity isn’t the main cause of this funny reflex.
