The stomach flu, or
gastroenteritis, is a viral infection that
attacks the stomach and small intestine and
generally lasts 1 to 3 days.
Caused by several
viruses such the adenoviruses, rotaviruses,
and the Norwalk virus, the stomach flu
settles in when we are in direct contact
with the virus.
Stomach flu treatment
is fairly straight forward and should be
followed quickly in an effort to avoid
dehydration.
Signs and symptoms of the stomach flu
include nausea, vomiting, diarrhea, stomach
cramps, loss of appetite, muscle aches, low
grade fever and chills.
If you realize that you have the stomach
flu then the first thing you must do is to
rest the stomach and intestines. How do you
do that? Well you stop eating solids and
start drinking only clear liquids. As you
improve you can begin to slowly add back in
solid foods by starting with soft and bland
foods since they are much easier for your GI
system to digest.
If you have been vomiting a lot, then it
is best to take in only small, frequent sips
of liquids. Vomiting may return if you drink
too much at one time.
It is important to take in fluids. Water
is ok if you haven't been vomiting for a
long time but if you have been throwing up
for some time then your body will need the
electrolytes you've lost replaced in order
to prevent complications. The depleted
electrolytes are easily replaced with sports
drinks such as Gatorade or Power Ade.
Some people find that weak tea and apple
juice are good choices that will stay down.
Again, remember to drink in small sips.
Chilling the liquids you plan to drink may
help you keep them down. Do not drink acidic
drinks such as orange juice or caffeinated
drinks like coffee. You may drink soft
drinks without caffeine such as 7-UP but
only after you have let them go flat and
they have lost all carbonation. Another big
thing to remember is absolutely no milk
until you no longer have diarrhea.
Once you have been free from vomiting for
several hours and you are managing to hold
down clear liquids then you can start to add
in soft and bland food. Soda crackers,
bananas, gelatin, plain noodles, toast, and
applesauce, and are good items to start off
with. Stay away from foods that are fatty,
spicy, acidic, or are high in fiber. You
should also stay away from dairy products.
It is ok to add them back into your diet
after 3 or 4 days have passed and you no
longer have any signs of the stomach flu.
Remember if you have been vomiting for
more than a day or have had diarrhea for
over 3 days, the check with your health care
provider. You may need further tests to rule
out dehydration or a more serious illness.
Dehydration is a potentially serious
complication of stomach flu and is a serious
problem for infants, children and seniors.
Dehydration occurs when your body has lost
too much fluid which occurs rather easily
with the diarrhea and vomiting of the
stomach flu. Severe dehydration requires
intervention and your healthcare provider
may order intravenous fluids in order to
replace the fluids you have lost.
The stomach flu is a serious illness and
should be monitored as such. It will
typically pass in just a few days but
without proper care and monitoring serious
complications can occur.
