What is Reverse T3? There is a lot of controversy about whether reverse triiodothyronine (rT3) should be measured to assess treatment in hypothyroidism. The normal thyroid gland secretes T4 (an inactive precursor), T3 (the active hormone), and reverse T3, a biologically inactive isomer of T3 that may block T3 from binding to the thyroid hormone […]
If you or someone close to you is struggling with hormone-related health issues, Dr. Friedman is the right choice. Here’s why: 1. Thinks Outside the Box Dr. Friedman is not afraid to look beyond the standard testing and treatment approaches, offering innovative solutions for his patients. 2. Expertise in a Wide Range of Endocrine Conditions […]
Reverse T3 (rT3) is a biologically inactive form of T3 (triiodothyronine), a thyroid hormone, that is created by peripheral 5 deiodination
A 24-hour urine collection (also known as a urinary free cortisol test or UFC) is an essential diagnostic tool used to measure
Night-time salivary cortisol testing is an essential, non-invasive tool that helps detect abnormalities in cortisol levels—particularly
Dr. Friedman's main approach to weight loss is to rule out any endocrine problems, such as hypothyroidism, Cushing syndrome, or growth hormone deficiency, that may lead to weight gain.
Understanding Thyroid Hormones: T4 and T3 The thyroid makes two hormones, T4 which has a long half-life meaning it can be given once a day. T4 gets converted to T3 which is the active form of the hormone and has a short-half life, meaning it has to be given frequently. Most patients with hypothyroidism are […]
There are some supplements that can be used to lower the TPO antibody. Selenium at 200 mcg a day (can be purchased at Trader Joes or online) can lower the TPO antibody as can Myo-Inositol plus from Omnibiotics, 2000 mg/50 mg once a day that can be purchased on Amazon. These supplements are helpful in […]
Dr. Friedman, when he was a fellow at the NIH in the 1990s, published a paper in the Journal of Clinical Endocrinology and Metabolism on the timing of giving glucocorticoids to patients with Addison disease. This paper involved sleep studies, and Dr. Friedman and colleagues found that a small dose of hydrocortisone given at bedtime […]
There is some confusion about the role of anti-thyroglobulin antibodies in diagnosing Hashimoto’s. A large study using a national database called the NHANES database showed that only the TPO antibodies correlated with hypothyroidism and not anti-thyroglobulin antibodies. The confusion seems to come that before the TPO antibody was identified, doctors used a test called an […]
