Viral Hepatitis
  • Viral hepatitis is an infection which is caused
    by a virus that mainly affects the liver. The
    liver is inflamed, becomes tender and gets
    swollen. The infection can destroy some parts of
    the liver.There are three basic types of viral
    hepatitis Hepatitis A Hepatitis B and Hepatitis
    C. These types of hepatitis depend on the type of
    virus that is responsible for the infection.A
    fourth virus that is known as the delta hepatitis
    virus causes hepatitis only in a person who is
    already infected with Hepatitis B. Other viruses
    attached with hepatitis include Hepatitis E and
    G.

How does viral hepatitis occur?
  • The viruses that cause hepatitis can be spread
    by
  • contamination from bowel movements
  • blood
  • inadequately cooked shellfish taken from polluted
    waters
  • sexual contact
  • contaminated needles
  • saliva
  • nasal mucus
  • Breast milk
  • Some types of viral hepatitis can be carried by
    carriers who show no symptoms. These people are
    called asymptomatic carriers.

How is viral hepatitis diagnosed?
  • Your doctor will review your symptoms and
    examine you. The doctor will press your abdomen
    to see if the liver is bigger in size or not. The
    doctor can perform some of the following lab
    tests
  • analysis of a urine sample
  • analysis of a stool sample
  • Blood tests, including tests to determine what
    type of hepatitis you have.

5
What are the symptoms of viral hepatitis?
  • Symptoms of viral hepatitis may not show until 2
    weeks to 6 months after a person is infected with
    the virus, or there may never be any obvious
    symptoms.When symptoms first occur, they can be
    the following typical symptoms of infection
  • loss of appetite
  • fever
  • general aches
  • fatigue

  • Other possible early symptoms are
  • itching hives
  • painful joints
  • loss of taste for cigarettes in smokers
  • After several days other symptoms may follow
  • nausea and vomiting
  • bad breath, bitter taste in the mouth
  • darkened urine
  • yellowish skin and eyes (jaundice)
  • pain below the ribs on the right side, especially
    when pressure is applied
  • Bowel movements that are whitish or light yellow
    and may be looser than normal

How is viral hepatitis treated?
  • Antibiotics are not useful in treating
    hepatitis. The usual treatment is bed rest, a
    balanced diet, and total abstinence from
    alcohol.Hospitalization is required only in
    more serious cases (for instance, if you become
    severely dehydrated). You should avoid taking
    certain drugs that are metabolized in the liver.
    Ask your doctor which drugs these are.
