Functions of Thyroid Hormones

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Synthesis and Regulation of Thyroid Hormones

Synthesis and Regulation of Thyroid Hormones

Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Regulation of Food Intake

Regulation of Food Intake

Short-term regulation of food intake primarily involves neural signals from the gastrointestinal (GI) tract, blood nutrient levels, and GI tract hormones. Communication between the gut and brain via vagal nerve fibers plays a significant role in evaluating the contents of the gut. Clinical studies have shown that protein ingestion produces a more prolonged response in these nerve fibers compared to an equivalent amount of glucose. Additionally, the activation of stretch receptors caused by GI...

Major Hormones and Their Functions

Major Hormones and Their Functions

Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Hormones and Bone Tissue

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Summary

Night eating frequency is linked to changes in thyroid hormones like thyroglobulin (Tg) and triiodothyronine (T3), but not thyroid sensitivity. Further research is needed to confirm these findings on thyroid function.

Background:

Thyroid function is influenced by circadian rhythms.
The impact of night eating frequency on thyroid function and sensitivity is not well understood.

Purpose of the Study:

To investigate the association between night eating frequency and thyroid function and sensitivity.
To analyze the influence of night eating on thyroid hormone indices and sensitivity markers.

Main Methods:

Utilized data from 6093 participants in the U.S. National Health and Nutrition Examination Survey (2007-2012).
Assessed night eating frequency via 24-hour dietary recall (food intake between 10:00 PM and 4:00 AM).
Analyzed thyroid hormones (T3, T4, FT3, FT4, TSH, Tg, TPOAb) and sensitivity indices (FT3/FT4, TSHI, TT4RI, TFQI) using weighted regression analyses, including subgroup and interaction tests.

Main Results:

Higher night eating frequency was associated with increased thyroglobulin (Tg) levels (OR 1.223) and decreased triiodothyronine (T3) and thyroid peroxidase antibody (TPOAb) levels.
The association between Tg and night eating was stronger in individuals with diabetes mellitus (DM).
The association between TPOAb and night eating was stronger in individuals without DM.
No significant differences in thyroid hormone sensitivity were observed based on night eating frequency.
Observed hormone fluctuations remained within normal clinical ranges.

Conclusions:

Night eating frequency shows a significant association with specific thyroid function markers.
Thyroid hormone sensitivity does not appear to be significantly affected by night eating frequency.
While associations are noted, further studies are required to establish causality between night eating and thyroid function.
