Hepatitis B

Hepatitis B is the most common serious liver infection in the world. It is thought to be the leading cause of liver cancer.

The World Health Organization estimates that hepatitis B infections lead to more than one million deaths every year.

What causes hepatitis B?

The disease is caused by the hepatitis B virus (HBV) that attacks the liver.

The virus is transmitted through blood and bodily fluids that contain blood.

This can occur through direct blood-to-blood contact, unprotected sex, and illicit drug use.

It can also be passed from an infected woman to her new-born during the delivery process.

Does the virus always pose a health threat?

It is thought that about one in three of the world's population is infected by HBV.

However, about 50% of those who carry the virus never develop any symptoms.

About nine out of ten people infected with HBV will eventually clear the virus from their bodies. But about 5-10% of infected adults will become chronic hepatitis B carriers, often without even knowing it.

What are the symptoms?

The virus can cause a range of problems, including fever, fatigue, muscle or joint pain, loss of appetite, nausea and vomiting.

Chronic carriers have an increased risk of developing liver disease such as cirrhosis or liver cancer, because the hepatitis B virus steadily attacks the liver.

Chronic carriers will usually have on going inflammation of the liver and may eventually develop cirrhosis and liver cancer.

About 1% of people who are infected develop an extreme form of disease called acute fulminant hepatitis.

This condition can be fatal if not treated quickly. Sufferers may collapse with fatigue, have yellowing of the skin and eyes (jaundice) and develop swelling in their abdomen.

How is it treated?

There are several drug treatments available to treat hepatitis B.

Patients may be put on a four month course of injections of the drug interferon.

An alternative treatment is a drug called lamivudine which is taken orally once a day. Treatment is usually for one year. Sometimes lamivudine is combined with interferon.

Chronic patients may require a liver transplant.

Can it be prevented?

Yes, by the use of a safe and effective vaccine.

However, for the 400 million people world-wide who are already carriers of HBV, the vaccine is of no use.

I tried to donate blood for the first time in my life about 4 years ago, and the local county health department telephoned me that afternoon and said I needed to go to see a doctor immediately because I had hepatitis B. I had absolutely no symptoms. I had several blood tests over the course of a year or so, and my doctor said I was a chronic carrier. My sister had Down's syndrome, and my doctor said I probably got it from her as she lived in an institution for a period of time. As the disease progressed all medication stopped working, i was introduced to Health herbal clinic in Johannesburg who have successful herbal treatment to hepatitis B. I spoke to few people who used the treatment here in USA and they all gave a positive response, so i immediately purchased the hepatitis B herbal formula and commenced usage, i used the herbal supplement for only 7 weeks, all symptoms gradually faded away, herbs are truly gift from God. contact this herbal clinic via their email healthherbalclinic @ gmail. com or visit www. healthherbalclinic. weebly. com
