What is T4 Hormone
Your thyroid gland is a perfect example of your body’s physical and neurological functions working in tandem. When things are going right, your body has the ability to use a series of processes to regulate itself. However, if one cog in these self-regulatory processes is off, it can affect your entire body.
The key to understanding your thyroid condition is hormones. This article will look at one hormone in particular: T4.
A Delicate Mechanism
Your thyroid gland is made up of the only cells in your body that can absorb iodine. These cells trigger a chemical reaction between the iodine they absorb and amino acids already present in the gland to produce hormones that every other cell in your body depends on.
The basic function of your thyroid gland is to convert the iodine found in foods into hormones that stimulate your cellular, metabolic, and immune responses. These hormones go through different stages of development.
T4 hormone stands for Thyroxine, the version of thyroid hormone that is released into your bloodstream. Your bloodstream carries it to cells and organs in need, so that they can function properly.
Of the hormones produced by your thyroid, about 80% are made up of T4 hormone and 20% of T3 hormone. T3 indicates how much hormone is being produced by the gland. T4 indicates how much hormone is being sent to support biological functions.
These levels are automatically assessed by the pituitary gland at the base of your brain. If it senses that not enough hormones are being produced; this peanut shaped gland will release a stimulant called thyroid-stimulating hormone (TSH).
Launching a Rescue Plan
TSH is your body’s natural rescue plan. It’s meant to work as a short-term hormone production accelerant. Once your hormone levels normalize, TSH is no longer released, thus, regulating the process. There’s one problem: this rescue plan isn’t designed to go on indefinitely.
Inflammation or disease can attack your thyroid gland and cause it to produce too much or too little hormone. This will either cause your T4 hormone levels to plummet or skyrocket, which affects the TSH regulation in the brain. The long-term effect of this imbalance causes processes in the body to become hyperactive or lethargic.
To conserve biological functions, the body will prioritize its T4 hormone use. This leads to inward changes in energy level and mental acuity and outward signs of metabolic and immune breakdowns.
The best course of action is to launch a secondary rescue plan using dietary changes, exercise, and supplementation to return the body to a state of delicate balance.
