What is Hepatitis B?

21:54 - 4 May , 2021


It is an infectious disease of the liver caused by the hepatitis B virus, which is transmitted through contact with blood and other body fluids of an infected person. 

Hepatitis B infection can be:

  • Acute: lasts less than six months, since with a strong immune system, the virus is eliminated. 
  • Chronic: it can last for years or a lifetime, depending on the strength of the immune system to eradicate the virus.

We are all at risk of contracting it, but the incidence is higher in:

  • Babies of mothers with hepatitis B.
  • Those who share needles, syringes, and other types of drug delivery devices.
  • Patients with diabetes, hepatitis C, or AIDS.
  • Patients receiving hemodialysis treatment.
  • People who have sex with multiple partners.
  • People who have lived with an infected person or traveled to countries with a high incidence of hepatitis B.
  • Health sector workers exposed to blood contact.

Signs and symptoms Hepatitis B

Hepatitis B symptoms can be mild or severe. It usually appears one to four months after infection and symptoms may not be reflected, but the most common are:

  • Diarrhea.
  • Pain in the abdomen and joints.
  • Tiredness and weakness.
  • High fever.
  • Light-colored stools.
  • Jaundice.
  • Nausea and vomiting.
  • Dark colored urine.
  • Lack of appetite.

In the case of chronic hepatitis B, symptoms can appear years after infection. Therefore, it is important to get regular check-ups, especially if you are at high risk of contracting it.

Diagnosis and treatment Hepatitis B

After analyzing your symptoms and medical history, your doctor will order blood tests and tests for viral hepatitis.

If you have acute hepatitis B, you may not need treatment. For a chronic infection that causes liver damage, you will likely require antiviral medications.

Potential risks:

Chronic hepatitis B can lead to complications, such as:

  • Cirrhosis.
  • Liver cancer. 
  • Liver failure.
  • Other conditions such as kidney disease. 


In addition to getting vaccinated against the hepatitis B virus, the best way to prevent it is:

  • Do not share needles or personal items like toothbrushes, razors, or scissors.
  • If you plan to have a tattoo or piercing, make sure the person doing it uses sterile tools.
  • Wear gloves if you are usually in contact with other people’s blood.
  • Use condoms during sex.
