My thoughts on her autospy...
The doco interviewed a forensic guy who explained the autopsy. Apparently, she had been recovering from anorexia physically when she died, she was a healthy weight. But inside, her heart had weakened. She had also been taking ipecac syrup, to hasten the purging (she was now binging and purging, common for anorexics to do when eating again) anti depressant ativan (lorazepam), laxatives, and synthroid..a thyroid medication which she shouldnt have cos nothing was wrong with her thyroid. She took it to hasten her metabolism.
She had skipped the anti depressant that she had been pescribed and took the syrup, the synthroid in massive doses, and had recovered from her use of laxatives, which ppl discovered she had been abusing, like they had found them everywhere. The ipecac when taken in large doses has a poison called emetic(sp.) and this, combined with the synthroid, which sped up her heart rate, contributed to her death. Four months previously, shed been hospitalised and had to be fed intravenously.
