Hepatitis B: Causes, Symptoms, Treatment, and Prevention
🌍 Hepatitis B is a serious viral infection that affects the liver, one of the most vital organs in the human body. It can lead to acute or chronic liver disease.
The good news? Hepatitis B is preventable through a safe and effective vaccine, and proper treatment can ensure a healthy life.
💡 What Is Hepatitis B?
**Hepatitis** means inflammation of the liver. When caused by the **Hepatitis B virus (HBV)**, the liver is damaged, affecting its ability to filter toxins, store energy, and process nutrients.
- Short-term infection (less than six months).
- Immune system often fights it off naturally.
- Most adults recover completely and become immune.
- Long-term infection (persists for more than six months).
- Virus remains in the body.
- Increases risk of **liver cirrhosis** and **liver cancer**.
🧫 Cause & Modes of Transmission
Cause
Hepatitis B is caused by the **Hepatitis B virus (HBV)**. It travels to the liver and multiplies inside liver cells, causing inflammation and damage.
🔁 Modes of Transmission (Blood or Body Fluids)
- **Mother-to-child** during childbirth.
- Unprotected **sexual contact** with an infected partner.
- Sharing **needles or syringes** (drug use).
- Blood transfusions (using unscreened blood).
- Sharing personal items (razors, toothbrushes) contaminated with blood.
- Accidental **needle-stick injuries** (healthcare workers).
Important: Hepatitis B does not spread through food, water, hugging, kissing, or mosquito bites.
🔍 Risk Factors & Symptoms
⚠️ Risk Factors
- Have unprotected sex with multiple partners.
- Inject drugs or share needles.
- Are born to an infected mother.
- Work in healthcare settings with exposure to blood.
- Live with someone who has chronic Hepatitis B.
- Receive dialysis or frequent blood transfusions.
🚨 Signs and Symptoms
Acute Symptoms (Early):- Fatigue, loss of appetite, nausea, vomiting, fever.
- Abdominal pain (right upper side).
- Dark-colored urine and pale stool.
- **Yellowing of the skin and eyes (Jaundice).**
- Persistent tiredness, joint or body pain.
- Enlarged liver, easy bruising or bleeding.
- Swelling of legs and abdomen (ascites).
- Confusion (in advanced liver disease).
🧪 Diagnosis of Hepatitis B
Doctors use specific blood tests to detect the infection and assess liver function:
💊 Treatment and Management
🩺 For Acute Hepatitis B:
- Usually **no specific antiviral treatment** is needed.
- Focus on support: Rest, hydration, and a balanced diet are essential.
- Avoid alcohol and medications harmful to the liver.
- Most adults recover fully within 6 months.
💊 For Chronic Hepatitis B:
- Requires **long-term medical monitoring** and sometimes antiviral treatment.
- Common antivirals: **Tenofovir** and **Entecavir**.
- Goal: Reduce viral replication to prevent **cirrhosis** and **cancer**.
- Regular follow-up (every 6–12 months) with blood tests and ultrasound.
🍎 Liver Care & Complications
✅ Do's & 🚫 Don'ts (Lifestyle)
- Eat fresh, whole foods.
- Stay hydrated.
- Maintain a healthy weight.

- Follow prescribed medication plan.
- **Avoid alcohol completely.**
- Avoid fatty or processed foods.
- Avoid smoking.
- Don’t take non-prescribed OTC meds without consulting your doctor.
⚕️ Possible Complications
Uncontrolled chronic Hepatitis B can lead to:
- **Liver cirrhosis** (scarring)
- Liver failure
- **Hepatocellular carcinoma** (liver cancer)
- Ascites (fluid buildup in abdomen)
- Encephalopathy (confusion)
🛡️ Prevention of Hepatitis B
1. Vaccination — The Best Protection 💉
- The vaccine is safe and **95% effective**.
- Usually given as 3 doses over 6 months (0, 1, and 6 months).
- All **infants** should get the first dose within 24 hours of birth.
- Adults at risk (healthcare workers, partners of infected people) should also be vaccinated.
2. Safe Practices
- Avoid sharing razors, needles, or toothbrushes.
- Practice safe sex (use condoms).
- Ensure all blood products are properly screened.
- Cover open wounds properly.
