Hypothyroidism VS Hyperthyroidism
Hypothyroidism and Hyperthyroidism are both conditions, where the thyroid gland cells are weakened and damaged, which affect almost every single activity that happens in the body such; metabolism, temperature, heart rate and much more.
The Thyroid gland produces three types of hormones, Callciumin, T4 and T3, which are sent to the cells throughout the blood system. Once our cells receive those hormones, they can use them to perform essential and vital tasks.
Hypothyroidism or Hashimoto’s disease is an under active thyroid state, where the thyroid gland doesn’t produce enough hormones (T4 and T3). The entire body slows down and gets into hypo state.
When suffering from an under active thyroid function your blood work would normally show high TSH levels than the normal.
On the other hand, hyperthyroidism or Graves’ disease is an overactive thyroid state, where the thyroid gland over produces T4 and T3 hormones and enters a Hyper state.
When suffering from an overactive thyroid function your blood work would normally show low TSH level than the normal.
Even though both conditions may be opposites, some people and animals would experience both conditions at the same time, going from a hypo to a hyper state and vice versa.
Under the same note, having either Hypothyroidism and Hyperthyroidism simply means – Weak and damaged thyroid gland cells and whether you develop a hypo or a hyper state simply depends on your genetic.
In other words if you suffer from Hypothyroidism most likely other people in your family may suffer from the same and vice versa, if you suffer from Hyperthyroidism, most likely you would have people in your family who suffer from an over active thyroid, goiters and similar symptoms that relate to an over active state.
The thyroid gland is part of a collection of glands that is called the Endocrine System, which also include the Pituitary gland Hypothalamus glands. Together they control and impact every little task in our body.
The pituitary gland hypothalamus glands are both located in the brain and have very important functions working together with the thyroid gland. The hypothalamus gland job is to direct the pituitary gland on how much to function, you can look at the hypothalamus gland as the pituitary gland big boss.
Part of the hypothalamus gland function is to read the levels of T4 and T3 in the blood and single the pituitary gland, by creating a special hormone that is called TRH – Thyrotropin Stimulating Hormone.
The TRH hormone then stimulate the pituitary gland to produce another hormone that is called TSH – Thyroid Stimulating Hormone, which then singles the thyroid gland how much T4 and T3 hormones to release.
For instance, if the hypothalamus gland reads too little T4 and T3 in the blood it will produce high levels of TRH which signals the pituitary gland to produce high levels of TSH, which then singles the thyroid gland to work harder to produce more T4 and T3 hormones as there are not enough at the moment.
On the other hand, if the hypothalamus gland reads too much T4 and T3 in the blood it will produce low levels of TRH which signals the pituitary gland to produce low levels of TSH, which then singles the thyroid gland to slow down and not produce as much T4 and T3 hormones as there are too much circulating in the blood at the moment.
You may look at the hypothalamus, pituitary and thyroid gland connection as house heating system. The thyroid gland being the actual heater, the pituitary gland is the thermostat and the hypothalamus being the person who controls the thermostats. The Hypothalamus just like a person, feels hot or cold, it adjusts the thermostat accordingly which directs the heater how much to function.
Symptoms With Normal TSH
testing the TSH levels in the blood would normally indicate about the activity of the thyroid gland, however, In some cases, other glands might be weakened and affect the Thyroid Gland.
For instance, in Hyperthyroidism, low level of TSH may indicate a low pituitary and hypothalamus function, but if your TSH is high most likely the other glands are working properly.
In addition, you may find that, in some cases, normal TSH levels fail to indicate thyroid weaknesses and therefore, a thyroid antibodies test should be done in addition to thyroid panel blood work.
Thyroid antibodies blood work tests the level of antibodies cells in the blood that are made by the immune system to fight acidosis and inflammation. The test would normally check the level of TPO (Thyroid Peroxidase Antibodies), Tg (Thyroglobulin antibodies) and TSH.
Thyroid antibodies test results
Negative no antibodies were found:
May mean your thyroid symptoms are most likely caused by something else.
Positive TPO and/or Tg were found:
May be a sign of Hypothyroidism. Most people with Hypothyroidism have high levels of either or both both Tg and TPO antibodies.
Positive antibodies to TPO and/or TSH receptor were found:
This may mean you have hyperthyroidism
You don’t need a doctor or a blood work to tell you how you feel. You already know if you suffer from some symptoms and that by itself should be everything you need to know in order heal.
Remember that synthetic drugs and supplements are never the solution as they can only take you so far. They mask the symptoms and once you get off them you feel way worse than you started.
