Hepatitis B chronic living in teenagers
Informed by recognized medical guidance
Overview
Chronic hepatitis B is a long-term infection of the liver caused by the hepatitis B virus. It stays in the body for more than six months and can cause liver damage over time. Many people with chronic hepatitis B do not feel sick, but they can still pass the virus to others.
Key facts
- Hepatitis B is spread through contact with infected blood or body fluids.
- Most people with chronic hepatitis B got it at birth or in early childhood.
- With proper care and monitoring, many people live healthy lives without serious liver problems.
Chronic hepatitis B is common worldwide, especially in parts of Asia, Africa, and the Pacific Islands. In the UK, it is less common, but some groups have higher rates.
Teenagers who were born to mothers with hepatitis B, or who were exposed to the virus in early childhood, are most likely to have chronic hepatitis B. It affects both males and females.
Symptoms
- Yellowing of the skin or whites of the eyes (jaundice)
- Dark urine or pale stools
- Severe pain in the upper right side of the belly
- Vomiting blood or passing black, tarry stools
- Sudden confusion or drowsiness
- ⚠Unexplained fever lasting more than a few days
- ⚠Persistent nausea or vomiting that prevents eating or drinking
- ⚠Unusual bruising or bleeding
Common symptoms
- Most teenagers with chronic hepatitis B have no symptoms at all.
Symptoms in children
- Children often have no symptoms, which is why the infection can go unnoticed for years.
Symptoms in older adults
- Older adults may experience fatigue, mild abdominal pain, or joint aches.
Causes
Main causes
- Chronic hepatitis B is caused by the hepatitis B virus. In teenagers, the most common way to get it is from their mother at birth (vertical transmission). It can also spread through sharing needles, razors, or toothbrushes with an infected person, or through unprotected sex.
Risk factors
- Born to a mother with hepatitis B
- Living in a region where hepatitis B is common
- Sharing needles or syringes
- Having unprotected sex with an infected person
- Living with someone who has chronic hepatitis B
When to see a doctor
See a doctor urgently if:
- If you have any symptoms of liver failure, such as jaundice, severe abdominal pain, or confusion
- If you are vomiting blood or have black stools
Book a routine appointment if:
- Visit a doctor regularly for blood tests to check liver health and virus levels
- Go for scheduled appointments every 6 to 12 months, or as advised
Diagnosis
Chronic hepatitis B is diagnosed with a simple blood test that looks for parts of the virus and antibodies your body makes.
Tests that may be done
- Blood test for hepatitis B surface antigen (HBsAg), which shows you have the virus
- Blood test for hepatitis B e antigen (HBeAg) and viral load (how much virus is in the blood)
- Liver function tests (LFTs) to see how well the liver is working
- Ultrasound scan of the liver to check for any damage
What to expect at your appointment
If you are diagnosed, the doctor will explain the results and what they mean. You will likely need regular blood tests and visits to a liver specialist (hepatologist) to monitor the infection.
Treatment
Not everyone with chronic hepatitis B needs immediate treatment. The decision depends on your age, liver health, and virus levels. The goal of treatment is to reduce liver damage and lower the risk of complications.
Self-care at home
- Avoid alcohol completely, as it can harm the liver
- Eat a healthy, balanced diet with plenty of fruits and vegetables
- Get enough sleep and manage stress
- Always use condoms during sex to protect your partner
- Do not share razors, toothbrushes, or nail clippers
Medical treatments
If treatment is needed, doctors may prescribe antiviral medications that help control the virus. These are taken by mouth daily. Treatment may last for several years or even for life. Your doctor will check your blood regularly to see how well the medicine is working. Do not start or stop any medication without consulting your healthcare provider.
When is surgery considered?
Surgery is not used to treat chronic hepatitis B itself. In rare cases of severe liver damage (like cirrhosis or liver cancer), a liver transplant might be considered. That decision is made by a specialist team.
Living with this condition
Most teenagers with chronic hepatitis B can go to school, play sports, and spend time with friends. You may need to take medication daily and have regular blood tests, but this should not stop you from living a full life.
Lifestyle tips
- Avoid alcohol and any drugs that could harm your liver
- Get the hepatitis A vaccine to protect your liver from another infection
- Inform your dentist and any healthcare provider that you have hepatitis B
- Always cover cuts and scrapes to prevent spreading the virus
- Keep up with school and hobbies—you can still achieve your goals
Diet and exercise
Eat a balanced diet with lots of vegetables, whole grains, and lean protein. Exercise regularly, but listen to your body—if you feel very tired, rest. Staying active helps your overall health.
Mental health and emotional wellbeing
It is normal to feel worried, angry, or sad about having hepatitis B. Some teenagers feel different or worry about telling others. Talking to a trusted adult, counselor, or support group can help. Remember, having hepatitis B does not define who you are.
Prevention
Yes, hepatitis B can be prevented with a safe and effective vaccine. For teenagers who already have chronic hepatitis B, prevention focuses on taking care of the liver and not passing the virus to others.
Vaccines
The hepatitis B vaccine is given as a series of shots. It is recommended for all babies and children in many countries. If you have not been vaccinated, ask your doctor about it. Note: the vaccine does not cure chronic hepatitis B, but it protects others from getting infected.
Screening programmes
People at high risk—such as those born in areas where hepatitis B is common, or those with a family history—should be tested. Regular screening helps catch the infection early and prevent liver damage.
Complications
If left untreated
- Liver scarring (cirrhosis) over many years
- Liver cancer (hepatocellular carcinoma)
- Liver failure, which can be life-threatening
Long-term outlook
With regular monitoring and the right treatment, most teenagers with chronic hepatitis B can live a long, healthy life. Many people never develop serious liver problems. Staying connected with your healthcare team and following their advice gives you the best chance of staying well.
