Reasons for Vomiting and Fever

• At one time or another, everyone has experienced
  a fever or has vomited. These two occurrences are
  not pleasant, but they do serve their purpose.
  Even though they make you feel miserable, this is
  actually your bodys way of keeping you healthy
  and safe.

VOMIT What is Vomit?

• You have many names for vomit, such as throw-up,
  barf, upchuck, hurl, or puke. The actual term for
  vomit is emesis, which is a Greek word for to
  vomit.
• Whatever you call it, its all the same thing
  vomit is soggy, half-digested food along with
  stomach mucus, saliva, stomach acids, and other
  chemicals that quickly exit up your throat and
  out of you mouth.

Why Do We Vomit?

• There are several reasons why we vomit. Food
  poisoning, illness, feeling nervous or scared,
  eating too much, pregnancy, and motion sickness
  are some reasons.
• For whatever reason you vomit, whenever something
  is upsetting your stomach, warning signals are
  sent to your brain to an area called the emetic
  center. This center tells your body to quickly
  get rid of whatever is upsetting you, and this is
  done by vomiting.

How Does Vomit Happen?

• Your digestive system carries food down your
  throat, into your stomach, and through your
  intestines which leads to the rectum.
• If you have a virus or other germs in your body,
  if you feel dizzy or nervous, or if you are
  pregnant or overeat, the muscles in your stomach
  push food up back to your mouth. Vomit is
  forcefully exerted out of your mouth so your body
  can feel better.

After We Vomit

• Even though vomiting can feel pretty disgusting
  and smell really gross, you will feel a lot
  better after you vomit.
• Remember, whatever made you feel bad is now gone,
  so its back to normal for your system.

FEVER What is Fever?

• The definition for fever is when the body
  temperature rises. To truly understand what a
  fever is, you first need to understand what the
  hypothalamus is.
• The hypothalamus is in the center of the brain
  and acts as the bodys thermostat. The
  hypothalamus tries to keep your body at its
  average temperature of 98.6F.
• Anytime that temperature rises, a fever will
  occur.

7
Why Do We Get Fever?

• A persons temperature might rise for many
  reasons.
• Fever occurs when the bodys immune response is
  triggered by pyrogens (fever-producing
  substances).
• Pyrogens usually come from a source outside the
  body such as viruses, bacteria, fungi, drugs, and
  toxins.
• Examples of pyrogens are colds, the flu,
  tonsillitis, ear infections, bronchitis, and
  tetanus.

How Does a Fever Happen?

• When the body senses fever-producing substances
  (pyrogens), the hypothalamus then raises the body
  temperature.
• Your body rises in temperature to make the
  conditions hotter. Shivering may occur, which
  will help increase the heat in your body.
• Most pyrogens cannot handle the temperatures that
  a fever brings, so the pyrogens will greatly
  weaken or be destroyed.
• Temperatures up to 100.8F are considered
  low-grade, a temperature between 101F - 102F is
  considered a mild fever, and a fever between
  102F - 103F is considered a moderate fever, and
  anything above 104F is considered a high fever.
  High fever, for a prolonged time, can damage the
  body.

After a Fever

• Once the fever-producing substance (pyrogen)
  disappears, the hypothalamus will set the body
  temperature back to normal.
• At this time, you might start to feel warm and
  you may sweat.
• Dont worry, these are signs that youre getting
  back to your old self.

OVERVIEW

• Even though you might feel lousy when you vomit
  or have a fever, your body is actually trying to
  help you get better.
• Different reasons like food poisoning, to
  overeating, or pyrogens such as the cold and the
  flu, are stimuli.
• Stimuli are things that cause an organism to
  perform an activity or start a reaction. The
  reactions are what occur in response to the
  stimuli like vomiting or having a fever.
