Hiccups come from contractions of your diaphragm. Everyone gets hiccups. They can come after a large meal, an alcoholic beverage, or even excitement that is sudden. Sometimes, but rarely, hiccups can be a sign of a medical condition that may require your attention. The only sign on a hiccup is the sound. Some people may notice a tightening feeling in their chest, throat, or even abdomen. If you are someone that has had hiccups for at least 48 hours and they are stopping you from eating, sleeping, or even breathing, you may need to consult your doctor. This could mean something more serious than just the hiccups.
There are certain factors that may put you at an even higher risk of getting the hiccups. These factors include your sex, mental or emotional issues, and surgery. Some people actual get the hiccups after they have come out of some type of anesthesia from the abdominal organs. Your doctor will first check things such as your reflexes, muscle strength, muscle tone, sight and sense of touch, coordination, and balance. Doctors will then run tests on you if they think you have a medical condition. They will run tests to check for infection, diabetes, and kidney disease. They may also do some imaging tests as well as endoscopic tests. Hiccups usually go away on their own unless you have some type of medical condition that is causing them. You can then take medications such as Chlorpromazine, Metoclopramide, and Baclofen, to treat long term hiccups. A doctor can suggest an injection of anesthetic to block your phrenic nerve which will then stop the hiccups. This is only if the doctor feels that none of the other treatments are working out for you. You will need to talk to your doctor to properly decide treatments.From the Web
