Angelina Jolie Battling Deadly Disease?

For months, Angelina Jolie, has looked like she?s suffering form a serious eating disorder. Her weight has plunged drastically, to a frightening 95 pounds, she has virtually no appetite, and insiders say she?s been dizzy, weak and shaky and even collapsed at one point.

But now a source tells that friends and family of Angie fear that all these symptoms may be pointing to something far more serious than an eating disorder ? they?re afraid Angie could be fighting a potentially deadly liver disease!

?People with hepatitis, which is an inflammation of the liver, suffer nausea, vomiting, anorexia, and diarrhea,? he says, adding that Angelina?s sallow complexion and dramatic weight loss could be telltale signals of the disease.

Angie had admitted that she was a heroin user, and she also has many tattoos ? both of which, medical experts note, are major risk factors for contracting hepatitis B and C, which can destroy the liver.

Jacob Teitelbaum, M.D. a Maryland based expert on diseases of the immune system and author of From Fatigued to Fantastic, points out that these two strains of the hepatitis virus can remain dormant in the body for years. And stress, say experts, can activate the virus, triggering visible symptoms.

Angelina has been particularly stressed since her mother, Marcheline Bertrand, died of cancer in January. ?Malnutrition and grief can affect the immune system and a virus that?s been dormant can attack, especially if you?re under stress,? explains Dr. Teitelbaum, who does not treat Angelina.

Angelina, meanwhile, is taking prescribed medication, says the source. ?She?s been having terrible mood swing sand it might be because of the medication,? the source adds. But while Brad seems concerned about her health, all is not well in his relationship with Angie, insiders report.

?They?re fighting a lot,? the source says. ?Angelina?s moods are up and down and often volatile. She?s lashed out at Brad telling him, ?The only reason I?m with you is you?re a mother to the children!? Brad has a much more nurturing, maternal side to him than Angelina.?

During the couple?s recent stay in Chicago where Angelina was working on her new movie, Brad didn?t visit her at work, say set insiders. ?While she seemed happy to be working, there was a certain sadness about her, maybe having to do with her personal life,? says one source. Another crew member adds, ?I don?t think they?re doing so well. Brad hasn?t been here, and Angie told me herself that they?re fighting.?

But despite the tenuous state of their relationship, Brad is still so concerned about Angie?s health, an insider says, that he had her draft a will. Should anything happen to her, he?d get full custody of their children. ?They did it in the beginning of July,? a source tells ?I think Brad felt it was necessary at the time. Angelina agreed because there are children involved, and she doesn?t want to leave things up in the air.?
