Again these videos are so helpful, after reading the chapters in the book regarding the Endocrine System and then watching these Great Videos it really reinforces everything, great Job!
The lecture is educational, but you lost me when you mentioned that you would not need to test their T3. In a perfect world and if a person is in relatively healthy condition and NOT overweight, the Tsh & T4 may be ok. However, I was normal in my tsh and t4 for a long time but still felt symptomatic. As it turns out, I was hypo at the cellular level while in the blood, the numbers appeared to be normal. My reverse T3 to Reverse T3 levels were off the charts. My body does not convert T4 to T3 well at all. I do agree that TSH should be tested but not as a PRIMARY test to determine Hypo or Hyper thyroid. T3 & reverse T3 and also Free T4 are MUCH more accurate. Studies are showing this more and more. I was put in a time release T3 only med and it changed my life completely around.
Actually I have a simplification: Hashimoto is a Japanese guy. The Japanese had the highest iodine intake in the world thanks to their seaweed kitchen. High iodine intake causes thyroid cancer. Hashi (original syndrome) is a form of thyroid cancer. NOT an autoimmune disease that 10% of the population could be diagnosed with because that many have elevated antibodies (and everyone has some apparently) that do not attack the thyroid but rather proteins. Hashi/hypo diagnosis is a convenient explanation why we feel down/have low metabolism and for prescribing thyroid crack cocaine when the body would rather conserve energy to deal with some chronic problems. At least imo that's a much more viable narrative of what's going on given the data.
It's not IODINE thats available in blood for the follicles to take in, it is IODIDE.. Iodide is then converted into Iodine in colloid with the help of peroxidase.
Thank you. I have had Graves disease for more than 15 years and have been taking PTU. I wonder if change in lifestyle would help to make the thyroid gland become normal again.
Hi, I am working on the pathophysiology of hypothyroidism. Your video really helps however could you help me go into the cellular level at exactly where hypothyroidism occurs (i.e correct me if I am wrong, but in my readings I found it occurs at the negative feedback to the pituitary gland) ???? Your help is much appreciated!
