The human body has hundreds of different hormones. Hormones are the triggers and the catalysts which cause the human body to function.
Every cell in the human body, every cell that makes up the human body, has a specific function. In order to perform its particular function, each cell must be fed nutrients and water. The nutrients and water enable the cell to perform whatever function that particular cell was designed/created to perform. Once that function is completed, the cell then expels the used up nutrients.
Each cell has a mechanism, a “door”, which will open in order to allow the cell to receive these nutrients and water.
This “door” mechanism on each cell, is controlled by a “lock”, which is called a Receptor Site.
Hormones can be visualized as a key, which must fit into that “lock”, that receptor site, in order to open that door. Some of the door locks, some of the receptor sites, are “master keyed”; they just need some hormone, any hormone, to cause them to open. Other “door locks” — other receptor sites — are specifically keyed to only allow certain specific hormones to open them.
For example, insulin is a hormone which opens the “door locks”, opens a cell via the receptor site, to allow that cell to receive glucose, which is food — nourishment — for the cell. Once the cell is fed, it can perform its intended function. Afterwards, the used up glucose is expelled, and then the hormone is detached from the receptor site, the door is closed and locked once again, and the used up hormone and used up glucose are flushed from the body.
There are three primary “sex” hormones in the body: Women have high levels of estrogen and progesterone, and a small amount of testosterone. Men have high to very high levels of testosterone, and small amounts of estrogen and progesterone.
The human body needs and requires that the levels of these three particular hormones to be within a certain ratio of each other, in order for the body to function properly, and in order to even think properly.
In born-women, PMS and menopause issues and symptoms are caused by the levels of these primary hormones, becoming too far apart in ratio. Which is exactly why born-women, who struggle with PMS and/or menopause, are often/usually given supplemental estrogen, or supplemental progesterone — called Hormone Replacement Therapy (HRT). This is done to return hormone levels to within proper ratios, so that she can return to functioning “normally”, physically, mentally, and emotionally.
The key purpose of hormone balancing, is to help the individual, male or female, to stop their physical, emotional, and mental suffering.
