An HBV infection causes damage to liver cells due to a viral infection, and neglecting treatment can lead to serious complications that threaten a patient’s life and overall health.
How is the virus transmitted?
The infection is transmitted from an infected person or a carrier to a healthy person through contaminated body fluids that enter the bloodstream. The most prominent methods include:
- Sexual contact: Through semen, vaginal secretions, or saliva.
- Contaminated blood: By sharing contaminated needles or accidental needle sticks in medical environments.
- Mother to fetus: The virus may be transmitted from an infected mother to her child during the birthing process.
- Personal tools: Sharing nail clippers, toothbrushes, or using non-sterile shaving and tattoo equipment.
Risks and hepatitis B complications
The disease may begin without clear symptoms, but it sometimes develops into critical health conditions, including:
Liver Cirrhosis
Cirrhosis occurs when scar tissue replaces healthy tissue due to continuous damage. Signs appear gradually, such as jaundice (yellowing of the skin and eyes), dark urine, abdominal swelling, easy bruising and bleeding, and unexplained weight loss.
Liver Failure and Cancer
- Liver failure: This may be acute, where the liver stops working within days, or chronic, developing over years of progressive damage.
- Cancer: Chronic HBV infection is a primary cause of liver cancer; symptoms include nausea, general fatigue, and pain and swelling in the abdominal area.
Portal Hypertension
Tissue fibrosis leads to increased pressure in the portal vein, causing:
- Ascites: Accumulation of fluids in the abdominal cavity, which may press on the lungs and cause shortness of breath.
- Esophageal and gastric varices: These varices can lead to severe bleeding.
- Encephalopathy: Neurological disorders including slurred speech, behavioral changes, and loss of consciousness.
Other effects and hepatitis C complications
Damage is not limited to the liver alone. Various types of hepatitis virus, especially type B and those causing hepatitis C complications, may affect other organs such as the kidneys, joints, skin, immune system, and cardiovascular system.
Prevention and Diagnosis Methods
Infection can be prevented by covering wounds, avoiding the sharing of personal tools, and sterilizing anything that has touched blood. Diagnosis is performed via physical examination and blood tests to determine the type of virus; a doctor may also perform a liver biopsy to assess the extent of damage.
Some research indicates that sleeping for less than 6 hours a night may reduce the antibody response to the hepatitis B vaccine, thereby reducing the likelihood of clinical protection.
FAQ
How do you get HBV infection?
Viral types are contagious and are transmitted through blood, fluids, or contaminated food (depending on the type), while inflammation resulting from medications or alcohol is not contagious.
What are the symptoms of hepatitis B?
Symptoms include loss of appetite, extreme fatigue, yellowing of the skin and eyes, dark urine, pain in the right side of the abdomen, and skin itching.
Is hepatitis B dangerous?
Yes, it can be dangerous if left untreated, as it can lead to liver cirrhosis, liver failure, or liver cancer.
When should you see a doctor?
Medical care should be sought immediately upon the appearance of the following signs:
- Clear yellowing of the skin or the whites of the eyes.
- Noticeable swelling in the abdomen or legs.
- Light-colored stools or very dark urine.
- Difficulty breathing or loss of consciousness.
- Appearance of bruises or bleeding without an obvious cause.
