Hepatitis B chronic living patient overview
Informed by recognized medical guidance
Overview
Chronic hepatitis B is a long-term infection of the liver caused by the hepatitis B virus. It means the virus stays in your body for more than six months and can cause liver damage over time.
Key facts
- It is a serious but manageable condition.
- Many people with chronic hepatitis B have no symptoms for years.
- Without treatment, it can lead to liver scarring (cirrhosis) or liver cancer.
Chronic hepatitis B is common worldwide, especially in parts of Asia, Africa, and Southern Europe. In the UK, it is less common but still affects thousands of people.
It can affect anyone, but it is more common in people born in areas where hepatitis B is widespread, people who have close contact with someone infected, and people who have unprotected sex or share needles.
Symptoms
- Sudden confusion or disorientation
- Vomiting blood or black tarry stools (signs of internal bleeding)
- Severe abdominal pain
- ⚠Jaundice that is getting worse
- ⚠Significant swelling in the abdomen or legs
- ⚠High fever with vomiting
Common symptoms
- Many people have no symptoms.
- Feeling very tired (fatigue)
- Mild fever
- Loss of appetite
- Nausea or vomiting
- Abdominal pain (especially in the upper right side)
- Jaundice (yellowing of the skin or eyes)
- Dark urine
Symptoms in children
- Children often have no symptoms, but may experience mild jaundice or fatigue.
Symptoms in older adults
- Older adults may have more noticeable symptoms such as severe tiredness, confusion, swelling in the legs or abdomen.
Causes
Main causes
- Infection with the hepatitis B virus, transmitted through contact with infected blood or body fluids (e.g., mother to baby during birth, unprotected sex, sharing needles)
Risk factors
- Born to a mother with hepatitis B
- Living in or traveling to areas where hepatitis B is common
- Unprotected sex with multiple partners
- Injecting drugs or sharing needles
- Sharing personal items like razors or toothbrushes with an infected person
- Working in healthcare with exposure to blood
When to see a doctor
See a doctor urgently if:
- If you have signs of liver failure such as confusion, vomiting blood, or black stools, call emergency services immediately.
Book a routine appointment if:
- If you know you have been exposed to hepatitis B
- If you have persistent symptoms like fatigue, jaundice, or abdominal discomfort
- For regular monitoring if you have chronic hepatitis B
Diagnosis
Chronic hepatitis B is diagnosed through blood tests that detect the virus or antibodies. Your doctor may also order imaging tests to check your liver.
Tests that may be done
- Blood tests (such as HBsAg and HBV DNA to measure virus levels)
- Liver function tests
- Ultrasound of the liver
- Liver biopsy (tissue sample) in some cases
What to expect at your appointment
Your doctor will review your medical history and perform a physical exam. You will have blood tests to assess the virus and liver health. You may need regular follow-up appointments every 6 to 12 months.
Treatment
Treatment aims to control the virus and prevent liver damage. Not everyone needs medication; your doctor will decide based on your virus levels and liver health. If treatment is needed, antiviral medicines are taken daily for many years.
Self-care at home
- Get plenty of rest
- Avoid alcohol completely (or as advised by your doctor)
- Avoid recreational drugs
- Eat a balanced, healthy diet
- Get vaccinated for hepatitis A if you are not immune
Medical treatments
Antiviral medications are used to suppress the virus. These are taken as tablets daily. The choice of medication depends on your individual situation. Your doctor will monitor you regularly to check if treatment is working. Never stop medication without consulting your doctor.
When is surgery considered?
Surgery is not typically used for hepatitis B itself. In cases of severe liver damage or liver cancer, a liver transplant may be considered.
Living with this condition
Living with chronic hepatitis B means attending regular check-ups, taking medications if prescribed, and living a liver-friendly lifestyle. Most people can work, travel, and have a normal social life.
Lifestyle tips
- Avoid alcohol completely (or limit strictly per doctor's advice)
- Don't smoke
- Practice safe sex to prevent transmission
- Get vaccinated for hepatitis A if not immune
- Tell your healthcare providers about your condition
Diet and exercise
Eat a balanced diet with plenty of fruits, vegetables, whole grains, and lean protein. Regular moderate exercise can help maintain a healthy weight and energy levels.
Mental health and emotional wellbeing
Living with a chronic condition can be stressful and may cause anxiety or depression. It's important to talk to your doctor or a counselor if you're struggling with your mental health.
Prevention
Yes, hepatitis B can be prevented with a safe and effective vaccine. It is part of routine childhood vaccination in many countries.
Vaccines
The hepatitis B vaccine is given as a series of injections. It is recommended for all infants, children at risk, and adults at increased risk. Even if you have chronic hepatitis B, the vaccine won't help you, but it can protect your family members.
Screening programmes
Screening is recommended for pregnant women, blood donors, and people at high risk. Early detection helps prevent spread and allows for monitoring.
Complications
If left untreated
- Cirrhosis (scarring of the liver)
- Liver failure
- Liver cancer
Long-term outlook
With regular monitoring and treatment when needed, most people with chronic hepatitis B can live a long and healthy life. Many people have a normal life expectancy, especially if they follow their doctor's advice and make healthy choices.
