Aging, infection, trauma, prolonged cortisol excess, somatostatin, dopamine or L-dopa, adrenaline (sometimes; Mannisto, et al., 1979), amphetamine, caffeine and fever can lower TSH, apart from the effect of feedback by the thyroid hormones, creating a situation in which TSH can appear normal or low, at the same time that there is a real hypothyroidism. -Ray [...]
Folia Med (Plovdiv). 2007;49(3-4):5-12. Rheumatoid arthritis and thyroid abnormalities. Staykova ND. Relationships between rheumatoid arthritis (RA) and the thyroid gland have been studied extensively for a long time. The studies of this problem have focused mainly on: (a) the functional and immune thyroid gland abnormalities in patients with previous history of RA, and (b) joint [...]
Probl Endokrinol (Mosk). 1987 Jan-Feb;33(1):18-21. [Characteristics of the hydration status of patients with hypothyroidism]. [Article in Russian] Nazarov AN, Lobachik VI, Zhidkov VV, Borisov GI, Abrosimov SV. The hydratation status of 15 patients of various age groups with hypothyrosis was studied using nuclear physical methods. Their body composition was calculated. All the examinees demonstrated considerable [...]
Hypothyroidism is a very common cause of increased serotonin (e.g. Henley, et al., 1998), and it the thyroid hormone is supplemented until symptoms are resolved, it’s likely that the serotonin will have been normalized. -Ray Peat, PhD Hypothyroidism increases the formation of serotonin, as does cortisol (Henley, et al., 1997, 1998; Neckers and Sze, 1976). [...]
The thyroid hormones associate with three types of simple proteins in the serum: Transthyretin (prealbumin), thyroid binding globulin, and albumin. -Ray Peat, PhD Transthyretin, which carries both vitamin A and thyroid hormones, is sharply decreased by stress, and should probably be regularly measured as part of the thyroid examination. -Ray Peat, PhD Clin Chem Lab [...]
Energy production and resting body temperature regulate many functions. Ample energy is required to relax fully and sleep deeply. The key to quality sleep is high energy metabolism and maintaining optimal body temperature (98-98.6F). Children sleep well because of their ability to maintain a high body temperature and produce energy and carbon dioxide. The combination [...]
The altitude itself helps the thyroid to function normally. For example, one study (Savourey, et al., 1998) showed an 18% increase in T3 at a high altitude, and mitochondria become more numerous and are more efficient at preventing lactic acid production, capillary leakiness, etc. -Ray Peat, PhD Eur J Appl Physiol Occup Physiol. 1998;77(1-2):37-43. Pre-adaptation, [...]
