Gambaran keseluruhan
Hepatitis B is a viral infection that causes inflammation of the liver. The liver is a vital organ that helps digest food, store energy, and remove toxins. Most people with hepatitis B recover fully, but some develop a long-term (chronic) infection that can lead to serious liver damage.
Fakta utama
- Hepatitis B is spread through contact with infected blood or body fluids, such as from sharing needles or unprotected sex.
- Many people with hepatitis B have no symptoms, especially when first infected.
- A safe and effective vaccine can prevent hepatitis B infection.
Hepatitis B is common worldwide. In the UK, it is less common than in some parts of Asia and Africa, but cases still occur, especially among people born in countries where hepatitis B is widespread.
Anyone can get hepatitis B, but it is more common in people who have contact with infected blood or body fluids, such as healthcare workers, people who inject drugs, and babies born to infected mothers.
Gejala
- Signs of severe liver damage: confusion, unusual sleepiness, or difficulty waking up
- Vomiting blood or passing black, tarry stools
- Severe abdominal pain that does not go away
- ⚠Yellow skin or eyes (jaundice) that appears suddenly
- ⚠Dark urine and pale stools
- ⚠Severe tiredness that interferes with daily activities
Gejala biasa
- Feeling very tired
- Loss of appetite
- Nausea or vomiting
- Pain in the upper right side of the belly (abdomen)
- Jaundice (yellowing of the skin and whites of the eyes)
- Dark urine and pale-colored stools
Gejala pada kanak-kanak
- Most children under 5 with hepatitis B have no symptoms at all.
- If symptoms do occur, they are usually mild, such as tiredness or poor feeding.
Gejala pada orang dewasa yang lebih tua
- Older adults are more likely to have symptoms, which can be more severe.
- They may also be at higher risk of developing chronic hepatitis B.
Punca
Punca utama
- Hepatitis B is caused by the hepatitis B virus (HBV). It is spread when infected blood, semen, or other body fluids enter a person’s body.
- Common ways include: sharing needles or syringes, unprotected sex with an infected person, from an infected mother to her baby during birth, or by accidental needle sticks in healthcare settings.
Faktor risiko
- Living in or traveling to areas where hepatitis B is common (e.g., parts of Asia, Africa, the Pacific Islands)
- Having unprotected sex with multiple partners or with someone who has hepatitis B
- Injecting drugs or sharing drug equipment
- Being a healthcare worker who may be exposed to blood
- Being born to a mother infected with hepatitis B
- Having a weakened immune system (e.g., from HIV or certain medications)
Bila perlu berjumpa doktor
Jumpa doktor dengan segera jika:
- If you have symptoms of severe liver damage (see emergency signs above), call your local emergency number immediately.
- If you develop jaundice (yellow skin or eyes), dark urine, or pale stools, see a doctor the same day.
Buat temujanji rutin jika:
- If you think you may have been exposed to hepatitis B – for example, through a needle stick or unprotected sex – talk to your doctor as soon as possible. You may need a vaccine or medication to prevent infection.
- If you have ongoing fatigue, nausea, or abdominal discomfort that does not go away, make a routine appointment.
Diagnosis
Hepatitis B is diagnosed with a simple blood test. The test checks for signs of the virus or antibodies that your body makes to fight it.
Ujian yang mungkin dilakukan
- Blood test for hepatitis B surface antigen (HBsAg) – to see if you currently have the virus
- Blood test for hepatitis B core antibody (anti-HBc) – to see if you have ever been infected
- Blood test for hepatitis B surface antibody (anti-HBs) – to see if you are immune (from past infection or vaccine)
Apa yang diharapkan semasa temujanji anda
The blood test is quick and is done at your doctor's office or a clinic. You may need to wait a few days for results. If you have chronic hepatitis B, your doctor may also recommend imaging tests (like an ultrasound) to check your liver.
Rawatan
Treatment for hepatitis B depends on whether the infection is acute (short-term) or chronic (long-term). Most acute infections do not need medicine and clear up on their own with rest and good nutrition. Chronic hepatitis B is managed with antiviral medications that help control the virus and prevent liver damage. Your doctor will decide the best treatment plan for you.
Penjagaan diri di rumah
- Get plenty of rest – your body needs energy to fight the virus.
- Drink lots of fluids, especially water, to stay hydrated.
- Eat a balanced diet with fruits, vegetables, and whole grains.
- Avoid alcohol completely – it can harm your liver.
- Do not take any new medicines, including over-the-counter or herbal remedies, without checking with your doctor.
Rawatan perubatan
For chronic hepatitis B, antiviral medications are used to reduce the amount of virus in your body and lower the risk of liver damage. Treatment is usually long-term and may involve one or more medicines. Your doctor will monitor you regularly with blood tests and liver scans to see how well the treatment is working and adjust it if needed. In some cases, a liver transplant may be considered if the liver is severely damaged.
Bila pembedahan dipertimbangkan?
Surgery is not a common treatment for hepatitis B itself. If the infection leads to severe liver damage or liver cancer, a liver transplant may be an option. This is only considered after other treatments have been tried and your doctor has done a thorough evaluation.
Hidup dengan keadaan ini
Living with hepatitis B, especially the chronic form, means taking care of your liver and overall health. You will need regular check-ups with your doctor. Most people with chronic hepatitis B can live full, active lives by following their treatment plan and making healthy choices.
Tip gaya hidup
- Avoid alcohol – even small amounts can damage your liver.
- Do not share needles, razors, toothbrushes, or anything that might have blood on it.
- Use condoms during sex to protect your partner from the virus.
- Tell your healthcare providers that you have hepatitis B so they can protect themselves and you.
- Get vaccinated against hepatitis A if you are not already immune – it is safe and recommended.
Diet dan senaman
Eat a healthy, balanced diet that is low in fat and includes plenty of fruits, vegetables, lean proteins, and whole grains. Avoid fatty or fried foods. Gentle exercise like walking or swimming can help keep you fit and improve your mood. Talk to your doctor before starting any new exercise routine.
Kesihatan mental dan kesejahteraan emosi
Being diagnosed with a chronic infection can be stressful. It is normal to feel anxious, sad, or worried about your health and the future. If you are struggling, talk to your doctor or a mental health professional. You are not alone.
Pencegahan
Yes, hepatitis B can be prevented with a safe and effective vaccine. It is recommended for all babies, children, and adults at risk. Other prevention measures include practicing safe sex, not sharing needles, and wearing gloves if you might come into contact with blood.
Vaksin
The hepatitis B vaccine is given as a series of injections, usually over 6 months. It is very effective at preventing infection. In the UK, it is offered to all babies as part of the routine childhood vaccination schedule, and to adults at higher risk.
Program saringan
Screening for hepatitis B is not routine for everyone, but it is recommended for pregnant women, people born in countries with a high rate of hepatitis B, and people with certain risk factors. Talk to your doctor about whether you should be tested.
Komplikasi
Jika tidak dirawat
- Chronic hepatitis B can lead to serious liver damage, including cirrhosis (scarring of the liver) and liver cancer.
- People with chronic hepatitis B have a higher risk of developing liver failure.
- A small number of people with acute hepatitis B may develop a severe form called fulminant hepatitis, which can be life-threatening.
Pandangan jangka panjang
The outlook for hepatitis B is generally good, especially with early detection and proper care. Most adults with acute hepatitis B recover completely. For chronic hepatitis B, treatments can control the virus and prevent complications, allowing many people to live long, healthy lives. Regular monitoring and a healthy lifestyle are key.
