What are hiccups?
Hiccups are sudden and sometimes painful contractions of the
diaphragm. The diaphragm is a thin layer of muscle that
separates the chest from the abdomen (belly). When we
breathe, the diaphragm muscle moves up and down as we take
air in and push it out. When you hiccup there is a loud
sound in the throat as air is suddenly sucked in.
How do they occur?
Most of the time one or a few hiccups happen because the
diaphragm muscle is irritated, often by something as simple
as a very cold, very fast, or very big drink. Eating too
fast or too much, eating hot and spicy foods or liquids,
drinking carbonated or alcoholic beverages, sudden
excitement, or a sudden change in temperature may trigger
hiccups.
Sometimes the hiccups don't stop and they last for hours.
In these cases it is necessary to look for the cause and
there are many possibilities. The most common causes are
related to problems with a nerve or a chemical imbalance in
the blood. These problems may overstimulate the diaphragm.
This causes the diaphragm muscle to contract too often and
too vigorously.
Examples of the wide variety of things that can cause
prolonged hiccups are: a foreign body in the ear touching
the eardrum, kidney failure, pneumonia, and abdominal
surgery.
How are they diagnosed?
Everyone has hiccups from time to time. Usually they need
no diagnosis or treatment. But when hiccups last several
hours, you should tell your health care provider. If you
also have chest pain or abdominal pain that continues
between the hiccups, you need to call your health care
provider or 911 right away.
Your provider will ask about your medical history and your
medicines. You will have a thorough exam of your nervous
system. You may have blood and urine tests to look for a
chemical imbalance or kidney problems.
How are they treated?
The treatment depends on the cause. If there is a specific
cause, such as a kidney problem or pneumonia, treating the
medical problem may cure the hiccups.
Sometimes gently pulling on the tongue will stop the
hiccups. This affects the nerves that control the
diaphragm.
Medicines, such as seizure medicines or sedative, are also
sometimes used to try to give relief.
Sometimes babies get hiccups while feeding. Change the
baby's position and try burping the baby. If the hiccups
don't go away after a few minutes, give the baby some water.
Wait until the hiccups are gone before feeding again.
How long will the effects last?
Most of the time, hiccups are harmless. Hiccups usually
start suddenly and stop after a few seconds or minutes.
Prolonged attacks are more serious. Call your health care
provider if hiccups last longer than 48 hours or if you have
frequent, repeated attacks.
How should I take care of myself?
If you are being treated for hiccups that have lasted
several hours or longer, follow your health care provider's
directions for stopping the hiccups.
How can I prevent hiccups?
If you tend to have hiccups often, try to avoid the things
that may cause them, such as
overeating, eating or drinking too fast, or drinking
alcohol. You may be able to figure out what causes your
hiccups and avoid that activity.
And if you are unable to prevent the hiccups, pulling on
your tongue really is an effective way of stopping them.
