Optimizing thyroid function requires a whole body approach. A blood sample allows measurement of hormone levels accurately. Instead, they involve functional changes in thyroid levels. Addressing gut health is often part of a complete hypothyroidism treatment plan. This is especially common in perimenopause, when progesterone drops and estrogen becomes relatively dominant. But for many patients — especially those under chronic stress, dealing with gut issues, or with elevated cortisol — the conversion is impaired. You can have plenty of T4 on paper and still have all the symptoms of low thyroid. Your thyroid makes mostly T4, which your body then converts to the active form. For patients with Hashimoto’s or poor gut health, reducing inflammation and restoring gut function improves thyroid hormone conversion and medication absorption. In general, dose conversions are more guesstimates based on what doses in clinical trials provided equivalent results for vasomotor symptoms and some data on hormone levels. The Canadian Menopause Society has just released a conversion table for menopause hormone therapy, including the recommended doses of progestogens (you can find it here). If estrogen dominance is raising thyroid binding globulin, correcting that imbalance with bioidentical progesterone allows thyroid hormone to circulate freely again. High estrogen raises thyroid binding globulin (TBG) — a protein that grabs thyroid hormone and takes it out of circulation. This is one of the main reasons we always test cortisol alongside thyroid hormones. Could the answer lie in the difference between free and total thyroid hormone measurements? High doses of estradiol are not necessarily required if estradiol is used in combination with an adequately effective antiandrogen, for instance cyproterone acetate, bicalutamide, or a gonadotropin-releasing hormone agonist or antagonist. After gonadectomy, testosterone suppression is no longer needed and lower doses of estradiol, such as the moderate doses, can be used instead. For transfeminine people who have not yet candy96.fun undergone or do not plan to undergo gonadectomy, a high to very high dose of estradiol can be used to achieve strong suppression of testosterone levels. Due to the variability in estradiol levels between individuals, the appropriate doses will often not be the same for different people. Changes in thyroid binding proteins may affect thyroid test results without true dysfunction. Total T3 test measures overall levels of T3 in a blood sample. This includes protein bound hormones and free hormones. Slightly higher doses are required for injectable estradiol esters relative to endogenous production amounts since they contain less estradiol by weight due to the ester components (Table). C Much lower doses of transdermal estradiol can be used in the case of genital application relative to conventional skin sites (potentially e.g. 5-fold lower doses for similar estradiol levels) (Aly., 2019). Low Free T3, high Reverse T3, or elevated antibodies can all produce hypothyroid symptoms with a completely normal TSH. Many people with Hashimoto’s have normal TSH for years while the damage builds. Elevated antibodies indicate Hashimoto’s thyroiditis — an autoimmune condition where your immune system attacks your thyroid. Your body can convert T4 to either active T3 or to reverse T3 — a mirror-image molecule that blocks the T3 receptor without activating it. How does one convert between different estrogens in menopause hormone therapy (MHT)? This is what we call subclinical or functional hypothyroidism, and it is exactly what our full panel is built to catch. For most patients, early changes show up within a few weeks — energy, mood, and body temperature often improve first. Your first visit starts with a thorough history — we want to hear everything, including symptoms you have been told are not related to your thyroid. We address any deficiencies in selenium, zinc, iodine, or iron that may be slowing thyroid production or conversion. We prescribe compounded bioidentical T3/T4 combinations or desiccated thyroid (NDT) based on your specific lab values and symptoms.
