Every woman’s menstrual cycle is different. It is a complex system that is controlled by many different glands and the hormones they produce. The average length of the menstrual cycle is 28–29 days, but this can vary between women and from one cycle to the next. The length of a menstrual cycle is calculated from the first day of your period to the day before your next period starts.
A guest blog post written by TASK Graduate, Gavin Luck-Jones (Edited by TASK).
What are the signs and symptoms of female hormone imbalance?
Irregular periods; menstrual cramps; infertility; mood swings; crying; moodiness; hot flushes; PMS; painful periods; heavy periods; bad skin; muscle pains, tenderness and stiffness; muscle weakness and fatigue, weight gain and much more…
The three main female hormones are:
- Estrone,
- Estrodial
- Estriol
They are all oestrogen’s, which regulate the menstrual cycle. Men also produce these in a much lower amount. The main male hormone is testosterone which females also produce in a much lower amount. The other important female hormone is progesterone which is mainly needed during the last 14 days of the menstrual cycle and on into pregnancy if fertilisation occurs.
The three main oestrogen’s need to be in the right ratios with each other to be balanced.
- Estrone 10%,
- Estradiol 10%
- Estriol 80%.
Estrone and Estradiol needs to be converted into Estriol. This is done by nutrients such as iodine, chromium, saw palmetto and magnesium. Iodine is the most effective and is found in supplements such as Black Walnut; Kelp and Hops; Energ-V and Licorice Root. Nearly everyone is deficient in iodine.
There are reflex points on the body that help kinesiologists to determine whether you are deficient in nutrients such as iodine, chromium, magnesium & many others. You can test yourself for iodine deficiency using the Lugol’s solution patch test, (put a splash of Lugols iodine solution on your skin and see how quickly it absorbs – blink and you might miss it!)
Female sex hormones work on feedback loops in the endocrine system
This involves the hypothalamus, the pituitary and the ovaries.
The positive feedback Loop
The process starts when the hypothalamus notices a small amount of oestrogen in the blood and so releases Gonadotropin Releasing Hormone (GnRH) which tells the pituitary gland to make and release Leutinising Hormone (LH) and Folicle Stimulating Hormone (FSH). LH and FSH tell the ovaries to secrete oestrogen during the follicular phase which stimulates the growth of egg-producing ovarian follicle. LH then stimulates the ovulation phase, where the egg is released from the ovaries. After ovulation comes the luteal stage whereby a structure called the Corpus Luteum is formed in the ovaries. LH tells the corpus luteum to secrete progesterone, which prepares the uterus for pregnancy. Oestrogen is also secreted but in a lesser amount. These processes are positive feedback loops.
The negative feedback loop
In contrast, a negative feedback loop occurs at the end of the luteul phase when the oestrogen and progesterone are both at high levels. They signal to the hypothalamus and pituitary to stop secreting GnRH, LH and FSH hormones. This causes the ovaries to stop releasing oestrogen and progesterone to maintain the correct balance and prevents the ovulation of a second egg. This is the end of the cycle, where the corpus luteum is degraded, oestrogen and progesterone is no longer secreted and the uterine lining is shed causing menstruation. This would be different if the egg is fertilised and pregnancy begins.
There are 4 parts to the menstrual cycle
The amount of oestrogen and progesterone needed for each of the four parts of the menstrual cycle are different and so the feedback loops act according to which phase the female is in. As a rough guide (everyone is unique); from day 1 to 7 (Follicular Phase) oestrogen levels begin increasing. Oestrogen levels then begin spiking and peak at day 13 (Ovulation). They drop downwards until about day 17, at the end of ovulation. They start to rise again and peak at day 21 (Luteul Phase) and then decrease during menstruation until day 28 when the cycle starts again. Progesterone does not make much of an appearance until day 8 on entering the ovulation stage in preparation for fertilisation and pregnancy. It takes a small dip after ovulation but then spikes up until day 21 before heading back down in preparation for the next cycle.
Signals from the hypothalamus
Female hormones in the body are regulated throughout each month depending on the signals from the hypothalamus and as the body goes through the menstrual cycle.
Oestrogen is primarily made in the ovaries, but also the placenta during pregnancy. A little bit is made by the adrenal glands and the breasts. Oestrogen is generally made from cholesterol. Cholesterol has been given a bad reputation as it is a lipid molecule. Lipid has become a word synonymous with fat, but that is not always the case.
Cholesterol is vital as a precursor to hormones
There are two types; high density lipoprotein (HDL) and low density lipoprotein (LDL). The density refers to the ratio of protein to cholesterol. LDL is the “bad” kind as it will increase risk of clogging blood vessels, but in contrast HDL will reduce these risks. LDL cholesterol levels are reduced with normal body weight when the body produces oestrogen, it also increases HDL cholesterol.
Heavy training athletes can have such a low amount of fat and cholesterol that they stop producing some hormones and therefore stop menstruating. They will not recommence menstruating until they get body fat back through not training so hard.
Kinesiologists can test for female hormone imbalances and correct them
Kinesiologists can test for female hormone imbalances and correct them using special techniques which address the structural, emotional and energetic realms of the body.
In addition, kinesiologists can test nutrition on these imbalances so as to find the right supplements that will put the hormones back into balance to reduce symptoms and/or boost fertility. These may include:
- Dong Quai
- Licorice Root
- Evening Primrose Oil
- Wild Yam
- Chromium
- Iodine
- Kelp
- Omega Oils
- Agnus Cactus and many more.
Your body has the answers
Asking the body via muscle testing leads to accurate answers about what the body needs to rebalance and be well. Systematic Kinesiology is the science of testing muscles – it enables us to evaluate and correct the motor responses of the central nervous system to create balance within the body. Systematic Kinesiology tells us where YOUR body is imbalanced and what YOUR body needs to balance it – emotionally, structurally, nutritionally and energetically.
To find your local Kinesiologist go to TASK UK Network
To learn Kinesiology go to our Course Pages. Having a session or training in Systematic Kinesiology helps you to identify the source of your symptoms and what is needed to return back to balanced health rather than guessing, not improving and wasting money. Systematic Kinesiology enables you to listen to your body.
