If you’ve frequently got a case of the hiccups, try slowing down when you eat and drink, suggests Dr. Plasker. Doing either too quickly causes your stomach to swell; this irritates your diaphragm, which contracts and causes hiccups. You may also get hiccups in emotional situations or if your body experiences a sudden temperature change. In both of these cases, the hiccups are a result of a glitch in your nerve pathways, which is why a sudden scare—which might shake up and reset your nerves—can sometimes end an episode.
