Dr. Holtorf discussed the controversies and inadequacies of standard thyroid testing on The Learning Channel airing in January, 2007. He demonstrated this fact with a case study patient brought to see Dr. Holtorf by The Learning Channel. This patient had extreme difficulty losing weight even after having gastric bypass surgery and suspected she had low thyroid despite having “normal” standard thyroid blood tests and being told by multiple specialists that her thyroid was fine. Dr. Holtorf clearly shows that she has abnormally low active tissue thyroid levels that were significantly lower than normal optimal levels and that her untreated low thyroid was likely a major contributor to her inability to lose weight.
