DO YOU FEEL LIKE YOU ARE SLOWING DOWN, GAINING WEIGHT, DRYING OUT, LOOSING MOTIVATION?
DO YOU FEEL LIKE YOUR HEART IS RACING and YOU ARE ON AN EVER- ACCELERATING TREAD MILL?
Do you experience Acid Indigestion, Anxiety, Brittle nails, Constipation, Dry skin/nails, Fatigue, Fluid retention, Hair loss, Headaches, Heat or Cold Intolerance, Hypoglycemia, Inappropriate weight gain, Infertility, Irritable Bowel Syndrome, Itchiness, Light-headedness, Low blood pressure, Moodiness, Ringing ears, Slow Wound healing?
A combination of the above symptoms just begs Dr. Health to investigate the levels of your thyroid hormone production.
What and where is your thyroid gland and what does it do?
Your thyroid is an endocrine gland that produces, stores and releases into your blood, specific hormone. Your thyroid stretches in an H-formation across your neck. It starts about a two fingers-width below your Adams apple and just after some cartilage, wrapping around the front of your larynx and trachea. It goes from there to the about your clavicles. Normally a thyroid is barely palpable although it does move with swallowing. Your thyroid has blood and lymph vessels, nerves, and ligaments to attach it moving cartilage, and a capsule. Plus, there are four wee parathyroid glands attached to it backside.
Your thyroid has the essential role of maintaining your body temperature. This temperature control regulates the speed at which each of your body’s cells will use raw materials to make energy and allow organs to function. For instance, the cells in the pancreas, heart, stomach all depend on temperature control in order to process carbohydrate to produce energy for the heart’s contractions which propel blood around your body.
If your thyroid does not precisely control your temperature, your cells slow down or accelerate their energy production in your body, known as metabolism.
If your temperature hovers below normal, it is hypothyroidism. Your metabolism slows and you may feel any number of associated symptoms: unintentional weight gain, sluggishness, fatigue, low libido. If stays above normal, it is hyperthyroidism. Your metabolism accelerates, so you burn off excessive energy with associated symptoms: anxiety, insomnia, sweating, rapid/irregular heartbeat, weight loss due to tissue destruction (muscles and organs).
Normally, your thyroid uses minerals (some more than others) and proteins (peptide chains) to make specific hormones that regulate your life-preserving body temperature.
How are the thyroid hormones produced?
You may know that T4 and T3 are hormones produced by your thyroid because they are the keys that control metabolism throughout your body. In order to make T4 and T3, your thyroid must have a supply of specific minerals and amino acids, have healthy cells and receive the correct signals requesting their production.
What is the number one mineral needed? It’s iodine which makes up 65% of T4 by weight. It is absorbed from your gut and carried through your blood to the thyroid.
Your thyroid gland is made up of compartments. These contain minute factory like structures (organelles), various minerals and proteins. Some organelles make larger proteins which connect to the Iodine and form your hormones, T4 and T3. In other areas calcitonin is produced which directs your utilizaiton of calcium. These hormones are released into your blood stream to be circulated to cells of organs throughout your body.
After T3 and T4 have signaled your cells to turn on the energy production, they are returned to the blood stream, carried to the liver and kidneys to be deactivated through de-structuring.
The initial production of these hormones is controlled by messages to your pituitary gland about their concentrations. If their concentrations are low, your brain’s hypothalamus gland produces Thyroid Releasing Hormone which it funnels to the anterior pituitary gland. Then the pituitary cells make and sends out TSH (thyroid stimulating hormone) to your thyroid gland to signal it to increase production of T4 and T3 and/or to release more.
TSH directly activates your thyroid’s enzymatic and cellular actions. However, substances can interfere with this command. For instance, an enzymatic cellular function which is a must for T3 and T4 production (iodide oxidation) can be derailed by anti-thyroid drugs, thus their levels drop.
Secondly, TSH ensures continuous control on key proteins’ gene expression. For instance, genetic abnormalities of key proteins prevent enzyme formation and disrupt one or both hormones production leading to goiter and hypothyroidism.
In a Nut Shell
Your butterfly-shaped thyroid gland is located in your anterior neck just below your Adam’s apple. Its lobes wrap about your trachea and connect via its tissue strap. It has arteries to bring in the blood, veins removing blood and lymphatic glands. Normally you cannot feel it.
The role of your Thyroid is production and storage of thyroid hormones. It has several parts with different cells. Each part and each type of cell has its role to fulfill. Its epithelia cells make follicles which are full of proteins essential to the hormone production. There are spaces between the follicles where parafollicular cells reside. Their role is to create and secret calcitonin which slows the rate of bone breakdown that decreases calcium dissolved in the blood.
The parathyroid glands, seated on the thyroid’s backside, produces PTH hormone which does the opposite of calcitonin. The two hormones ensure balanced calcium in your bloodstream. As these glands are endocrine glands, they secretes theirs hormones directly into the blood without using a duct.
Your thyroid hormones (T3 and T4) are sent out from your thyroid as fat soluble chemical messengers to other TARGET tissues: liver, heart, muscles. T3 and T4 bind to receptors on the plasma membranes of those tissues causing chemical changes inside of the tissues’ cells. BOOM!! Your cells make energy, your muscles contract, your heart pumps, life is good.
