Hepatitis A/B/C

Hepatitis A/B/C Explained

Hepatitis A is usually a short-term infection spread through contaminated food or water. Hepatitis B and C are most often spread through blood or body fluids (such as needles, sexual contact, or from mother to baby) and can become chronic, leading to scarring of the liver (cirrhosis), liver failure, or liver cancer over time if untreated. Many people with chronic hepatitis B or C have few or no symptoms for years, which is why screening and follow-up are so important.

Symptoms

Many people have no symptoms, especially with chronic hepatitis B or C. When symptoms do occur, they can resemble a “flu-like” illness with fatigue, nausea, and jaundice.

Symptoms include:
Tiredness or weakness
Poor appetite, nausea, or vomiting
Abdominal discomfort (especially in the upper right side)
Dark urine and pale or clay-colored stools
Yellowing of the skin or eyes (jaundice)

When to call

Call the office if you have been exposed to someone with hepatitis, have abnormal liver tests, or develop symptoms such as jaundice, dark urine, or persistent fatigue. Also call if you have known hepatitis and notice a change in your usual symptoms.

Seek emergency care for severe abdominal pain, confusion, heavy bleeding, very deep jaundice, or if you feel extremely unwell with symptoms such as shortness of breath, chest pain, or signs of shock.

Evaluation & Tests
Management & Treatment

Diagnosis is made with blood tests that look for specific viral markers and liver enzyme levels. Additional tests may include imaging or, in some cases, a liver biopsy or noninvasive fibrosis assessment to determine the amount of liver damage.

History of risk factors (travel, food exposure, tattoos, transfusions, needles, sexual exposures, birth country or family history)
Blood tests to detect hepatitis A/B/C antibodies and antigens and measure viral load
Liver function tests (AST, ALT, bilirubin, INR)
Assessment of liver scarring with noninvasive tests or liver biopsy when needed
Screening for related conditions (HIV and other infections) in chronic viral hepatitis

Hepatitis A usually resolves on its own with supportive care. Chronic hepatitis B and C are managed with antiviral medications that can suppress or eliminate the virus and reduce the risk of cirrhosis and liver cancer. Vaccines are available for hepatitis A and B, but not for hepatitis C.

Supportive care and rest for hepatitis A; avoid alcohol and certain medications
Antiviral therapy for chronic hepatitis B and C when indicated
Regular monitoring of liver tests, viral levels, and liver cancer surveillance in chronic infections
Vaccination for hepatitis A and B when appropriate
Lifestyle steps to protect the liver (no alcohol misuse, manage weight, avoid unnecessary medications/supplements)
