Could Your Fatigue Be Linked to Hepatitis B Immunity? Understanding Silent Symptoms

Could Your Fatigue Be Linked to Hepatitis B Immunity?

Many adults in the UK experience ongoing fatigue, aches, or bouts of low energy without an obvious cause. While stress and lifestyle factors top the list, did you know that your immunity status, particularly to Hepatitis B, could also play a role?

What are the symptoms of low Hepatitis B immunity?

Hepatitis B often gets overlooked because most people think of it as a purely liver-related issue. However, low immunity to Hepatitis B, especially for healthcare workers, frequent travellers, or those with certain medical histories, could mean you're at risk even if you don’t feel acutely ill.

• Unexplained tiredness
• Muscular aches
• General feeling of being run down

These symptoms can overlap with many health issues, which is why understanding your Hepatitis B immunity can be essential.

How does Hepatitis B immunity work?

Immunity to Hepatitis B is usually achieved through vaccination or after recovery from an infection. A blood test looks for specific antibodies called Hepatitis B surface antibody (IgG). If your levels are low, your body might not be fully protected against the virus. Learn more about Hepatitis B on the NHS website.

Should I get tested for Hepatitis B immunity?

Consider a test if you:

• Work in healthcare or social care
• Had vaccinations as a child, but not checked in adulthood
• Are planning to travel to countries with high Hepatitis B rates
• Live with or care for someone who has Hepatitis B

You don't need to feel unwell to benefit from knowing your immunity status. Testing empowers you to take control of your health.

Actionable next steps for everyone

• Review your vaccination history
• Maintain a healthy lifestyle to support your immune system
• If concerned, speak to your GP or a private healthcare provider
• For reassurance, consider a quick finger-prick blood test
