Understand the basics of Hepatitis B, screening guidelines, prevention, and why early awareness matters for your liver health.
Hepatitis B is an infection caused by the hepatitis B virus (HBV) that primarily affects the liver. While some people clear the infection on their own, others develop a long-term infection known as chronic hepatitis B.
Many people with hepatitis B have no symptoms, meaning a person can carry the infection without knowing it. Unmonitored chronic hepatitis B can gradually damage the liver and elevate the risk of liver cirrhosis and liver cancer. (World Health Organization)
Many individuals experience no symptoms, especially in the early stages. When symptoms do occur, they may include:
Because symptoms can be entirely absent, a blood test is the only reliable way to know whether you have hepatitis B. (World Health Organization)
Hepatitis B remains a significant global health challenge. WHO estimates that approximately 240 million people lived with chronic hepatitis B worldwide in 2024, with about 1.1 million associated deaths that year. (World Health Organization)
In Bangladesh, a 2022 systematic review and meta-analysis of studies published from 1995–2017 estimated the pooled prevalence of hepatitis B in the general population at approximately 4%. As this is based on older studies, it should not be interpreted as the exact current prevalence. (PubMed)
Hepatitis B screening is a blood test to determine whether you currently have the infection, had it in the past, or are protected against it. For adults being screened for the first time, the CDC recommends a triple-panel blood test:
| Test Panel | What it helps tell you |
|---|---|
| HBsAg | Whether there is a current hepatitis B infection |
| Anti-HBs | Whether you have protective immunity, usually from vaccination or previous infection |
| Total Anti-HBc | Whether you have been infected with hepatitis B at some point |
The three results together provide a comprehensive picture compared to a single test. (CDC) Why screening matters: You can feel completely healthy and still have hepatitis B. Early detection enables proper medical follow-up and prevents transmission. (CDC)
The CDC recommends that all adults aged 18 years and older be screened at least once. Pregnant women should also be tested to prevent mother-to-child transmission. Individuals with ongoing exposure risks may require periodic re-testing. (CDC)
Yes! Hepatitis B is entirely preventable with safe, effective vaccination available for infants, children, adolescents, and adults. Dosing schedules vary based on age, product, and medical background. (CDC)
Vaccination is vital because infections acquired during infancy or early childhood have a much higher likelihood of becoming chronic than adult-acquired infections. (World Health Organization)
Understanding MASLD, lifestyle modifications, physical activity guidelines, and nutritional principles for better liver wellness.
Fatty liver disease means that excess fat has built up in the liver. The condition is now commonly described as metabolic dysfunction-associated steatotic liver disease (MASLD) when it is associated with metabolic risk factors rather than heavy alcohol use.
Fatty liver can be mild and cause no symptoms, but in some people it can progress to liver inflammation, scarring (fibrosis), cirrhosis and other liver complications. Many people do not feel unwell, which is why appropriate medical evaluation and follow-up are important. (NIDDK)
Small changes made consistently can make a significant difference:
You do not need to start with intense exercise. Build up gradually:
Emphasize vegetables, whole fruits and whole grains while limiting simple sugars and processed foods. (NIDDK)
Vegetables, whole fruits, brown/red rice, oats, whole-wheat roti, fish, skinless chicken, eggs, dal, beans, lentils, unsalted nuts/seeds, low-fat/unsweetened dairy.
Soft drinks, sugary beverages, large quantities of fruit juice, sweets, desserts, cakes, pastries, deep-fried foods, highly processed items, saturated/trans fats, and excess refined carbs.
