Overview
Hepatitis is a medical term that means inflammation (swelling) of the liver. The liver is a large organ in your upper right belly that helps filter your blood, digest food, and store energy. When it becomes inflamed, it cannot work as well as it should. Hepatitis can be caused by viruses, alcohol, certain medicines, or your own immune system attacking the liver.
Key facts
- There are five main types of viral hepatitis: A, B, C, D, and E. Each spreads differently and affects the liver in different ways.
- Hepatitis B and C are the most common causes of long-term (chronic) liver disease worldwide.
- With proper care, many people with hepatitis recover fully. For chronic cases, treatment can control the virus and prevent liver damage.
Yes, hepatitis is very common around the world. Millions of people have some form of hepatitis, though many do not know it because they feel fine.
Anyone can get hepatitis, but the risk is higher in people who travel to areas where hepatitis is common, share needles, have unprotected sex, or drink a lot of alcohol. Some types, like hepatitis A, are more common in places with poor sanitation.
Symptoms
- Sudden confusion or extreme drowsiness
- Vomiting blood or black, tarry stools
- Severe abdominal pain that does not go away
- Shortness of breath or trouble breathing
- ⚠New or worsening jaundice (yellow skin or eyes)
- ⚠Dark urine or pale stools
- ⚠Persistent nausea and vomiting that prevents you from drinking enough fluids
- ⚠Unexplained bruising or bleeding
Common symptoms
- Fatigue (feeling very tired)
- Loss of appetite
- Nausea or vomiting
- Pain or discomfort in the upper right side of the belly
- Jaundice – yellowing of the skin or the whites of the eyes
- Dark urine (like tea or cola)
- Pale or clay-coloured stools
- Fever (mild)
Symptoms in children
- Many children have no symptoms at all, especially with hepatitis A or B.
- If symptoms do occur, they are usually mild, like a low fever, tiredness, or loss of appetite.
- Jaundice is less common in children than in adults.
Symptoms in older adults
- Older adults are more likely to have serious symptoms.
- They may have severe fatigue, confusion, or swelling in the belly.
- Jaundice tends to be more obvious and last longer.
Causes
Main causes
- Viral infections: hepatitis A, B, C, D, and E viruses are the most common causes.
- Alcohol: drinking too much over many years can damage the liver and cause alcoholic hepatitis.
- Medicines: certain drugs, including high doses of paracetamol (acetaminophen), can cause liver inflammation.
- Autoimmune disease: the body’s immune system mistakenly attacks liver cells.
- Other infections: such as cytomegalovirus or Epstein-Barr virus.
Risk factors
- Travelling to countries where hepatitis A or E is common
- Eating or drinking contaminated food or water (hepatitis A and E)
- Sharing needles, syringes, or drug equipment (hepatitis B and C)
- Having unprotected sex with multiple partners (hepatitis B)
- Being born to a mother who has hepatitis B or C
- Drinking a lot of alcohol over a long period
- Working in healthcare or being exposed to blood and body fluids
When to see a doctor
See a doctor urgently if:
- If you have any symptoms of hepatitis, especially jaundice or dark urine.
- If you think you have been exposed to hepatitis (for example, through contaminated food or a needle stick).
- If you have severe abdominal pain, confusion, or vomiting blood – call your local emergency number.
Book a routine appointment if:
- If you have ongoing fatigue, loss of appetite, or belly discomfort that lasts more than a few days.
- If you have a history of alcohol misuse or other risk factors and are concerned about your liver health.
- For routine screenings if you are at higher risk, such as healthcare workers or people born in areas with high hepatitis rates.
Diagnosis
Doctors diagnose hepatitis based on your symptoms, medical history, and tests. They will ask about your travel, alcohol use, and any possible exposure to the virus. Blood tests are the main way to find out which type of hepatitis you have and how well your liver is working.
Tests that may be done
- Blood tests to check liver enzymes (ALT, AST) and other markers of liver health
- Serology tests to look for antibodies against hepatitis viruses (to tell which virus is present)
- PCR tests to measure the amount of virus in your blood (viral load)
- Ultrasound of the liver to see if it is enlarged or scarred
- Liver biopsy – a tiny sample of liver tissue removed with a needle to check for damage
What to expect at your appointment
Most tests are quick and painless. You will have a blood sample taken from your arm. If further imaging is needed, you may have an ultrasound, which takes about 30 minutes. A liver biopsy is usually done with a local anaesthetic and you can go home the same day. Results can take a few days to a week.
Treatment
Treatment depends on the type of hepatitis and how severe it is. For acute (short-term) hepatitis, the goal is to rest and let the liver heal. For chronic (long-term) hepatitis, medicines can control the virus and prevent liver damage. If the liver is badly damaged, a liver transplant may be needed. Always follow your doctor’s advice – do not take over-the-counter medicines or herbal remedies without checking first, because some can harm the liver.
Self-care at home
- Get plenty of rest – your body needs energy to fight the infection and repair the liver.
- Drink enough fluids – water, clear broths, and electrolyte drinks help prevent dehydration.
- Avoid alcohol completely – it can make liver damage worse, especially during treatment.
- Eat a balanced diet with fruits, vegetables, and lean protein – avoid fatty or fried foods that are hard for the liver to process.
- Do not take any new medicines, supplements, or herbal products without asking your doctor.
Medical treatments
For viral hepatitis, doctors may prescribe antiviral medications that stop the virus from multiplying. For hepatitis B and C, treatment often involves a combination of antiviral drugs taken for several weeks to months. For autoimmune hepatitis, immune-suppressing drugs (corticosteroids) can reduce inflammation. For alcoholic hepatitis, the most important step is to stop drinking entirely. In severe cases, hospital care may be needed for fluids, nutrition, and close monitoring.
When is surgery considered?
Surgery is rarely needed for hepatitis itself. However, if the liver becomes severely scarred (cirrhosis) and stops working, a liver transplant may be considered. This is a major operation where a donor liver replaces the damaged one. It is only offered when other treatments are not effective.
Living with this condition
Living with hepatitis means taking care of your liver and your overall health. Most people with hepatitis can lead normal lives, especially if the condition is caught early. It is important to attend all follow-up appointments and take any prescribed medicines exactly as directed. If you have chronic hepatitis B or C, you will need regular blood tests to check your liver and viral load, usually every 6 to 12 months.
Lifestyle tips
- Avoid alcohol completely – it is toxic to the liver, especially when it is already inflamed.
- Make sure you are vaccinated against hepatitis A and B if you are not already immune.
- Practise safe sex – use condoms to reduce the risk of passing hepatitis B or C to others.
- Do not share personal items like toothbrushes, razors, or nail clippers – they can carry blood.
- If you inject drugs, always use new, sterile needles and never share equipment.
Diet and exercise
Eat a healthy diet rich in fruits, vegetables, whole grains, and lean proteins. Try to limit salt and sugar to avoid adding extra strain on the liver. Stay hydrated. Moderate exercise, like walking or gentle yoga, can help you feel better, but avoid intense workouts until you are fully recovered. Ask your doctor what level of activity is safe for you.
Mental health and emotional wellbeing
Living with a chronic liver condition can be stressful. You may feel anxious, sad, or worried about the future. It is normal to feel this way. Talk to your doctor or a counsellor about your feelings. Support groups can help you connect with others who understand what you are going through. If you feel overwhelmed, reach out to a mental health professional or a crisis helpline.
Prevention
Many cases of hepatitis can be prevented with simple steps. Vaccines are available for hepatitis A and B. Hepatitis C and E have no vaccine, but you can reduce your risk by avoiding contaminated food and water (for hepatitis E) and not sharing needles (for hepatitis C). Limiting alcohol intake and practicing safe sex also help protect your liver.
Vaccines
Vaccines can prevent hepatitis A and hepatitis B. The hepatitis A vaccine is given as two shots, six months apart. The hepatitis B vaccine is usually given as three or four shots over six months. A combined vaccine for both is also available. In many countries, these vaccines are part of routine childhood immunisation. Adults at risk should also get vaccinated. There is no vaccine for hepatitis C, D, or E yet.
Screening programmes
Screening is recommended for people at high risk, such as pregnant women, healthcare workers, people born in countries with high hepatitis rates, and people who inject drugs. Blood tests can find hepatitis early, even before symptoms appear. Early detection allows for treatment that can prevent liver damage and stop the spread of the virus.
Complications
If left untreated
- Chronic hepatitis can lead to cirrhosis – severe scarring of the liver that makes it hard for the liver to work.
- Cirrhosis can cause liver failure, where the liver stops working completely.
- Long-term hepatitis B or C increases the risk of liver cancer.
- Acute hepatitis can sometimes cause sudden liver failure, which is a medical emergency.
Long-term outlook
With good medical care, many people with hepatitis recover fully or manage the condition successfully. Acute hepatitis often clears up on its own. Chronic hepatitis can be treated effectively with antiviral medications, which can stop the virus and prevent liver damage. Even if cirrhosis develops, treatments can slow it down and keep the liver working for many years. Liver transplants are available for severe cases and have high success rates. The key is to see a doctor early, follow your treatment plan, and make healthy choices.
