The Endocrine Society has defined bio-identical hormones as ‘compounds that have exactly the same chemical and molecular structure as hormones that are produced in the human body’.
They are synthesised from a plant chemical extracted from yams and soy at a molecular level. They differ from synthetic hormones, which have a different molecular structure.
Typical symptoms related to hormonal imbalance are:
What is perimenopause?
As part of the menstrual cycle, the ovaries produce oestrogen and progesterone. They also produce androgens, which include testosterone. Hormone levels usually begin to change around the age of 40 and the perimenopause (the years just before menopause) is usually between 50 and 55. As hormone levels start fluctuating quite dramatically during perimenopause, women begin to have symptoms such as hot flushes, vaginal dryness, irregular periods and insomnia.
These hormonal changes are due to the ageing ovaries losing their ability to produce eggs and hormones. At this time, during the monthly cycle, women will have widely varying oestrogen levels as the ovaries continue to try to produce eggs. Often there will be cycles in which no ovulation occurs and no progesterone is produced. As a woman approaches menopause this can lead to irregular menstrual cycles with heavy or abnormal bleeding.
What is menopause?
At this point, the ovaries stop producing and releasing eggs (ovulating) each month and periods cease. The ovaries are no longer producing estradiol and progesterone (although they may continue to produce androgens). Menopause does not mean that there is no oestrogen in the body anymore. Women with more body fat will usually have more oestrogen than thinner women, because oestrogen is aromatised in fatty tissue. After menopause, there is much less oestrogen and testosterone in the body than before menopause, and very little progesterone.
This drop in hormone levels can have various effects, including the familiar symptoms of menopause such as:
What is surgical menopause?
A woman who has surgical menopause, in which her ovaries are removed (usually along with her uterus and fallopian tubes), will have a sudden drop in all sex hormone levels.
This sudden loss of hormones can cause severe symptoms and health problems, especially in younger women, unless adequate hormone replacement is provided.
What role does progresterone play in the body?
In addition to protecting the uterus, progesterone:
What role does testosterone play in women's bodies?
Testosterone is the hormone that provides women with muscle tone, sharp cognitive functions and libido. Due to declining ovarian and adrenal function, testosterone production tends to reduce with age, and women begin to experience confusion, weight gain and poor muscle tone, despite regular exercise. During menopause, levels will drop in excess of 33%. Balancing testosterone with oestrogen produces serotonin, which supports emotional balance. Without this, a woman can experience emotional instability, anxiety, irritability and sleep disturbance.
An imbalance of testosterone can result in muscle atrophy, osteoporosis, muscle and joint pain. The role of testosterone in the body is to build muscle and promote muscle tone, increase libido, strengthen bone and, in some, it will improve mood and metabolism. There is an abundant amount of information supporting and rejecting the supplemental use of testosterone in hormone replacement therapy (HRT) for postmenopausal women. Theoretically, it makes sense that there are benefits of replacing all hormones that are decreased during menopause, including testosterone.
Further evaluation is needed to clearly determine the role of testosterone in postmenopausal women. If there is a family history of breast cancer, supplementation is not conventionally recommended, although some doctors believe that there may be a benefit in maintaining normal levels through supplementation. Testosterone supplementation is generally warranted in women complaining of low libido and sexual problems.
What role does oestrogen play in the body?
Oestrogen is possibly the most important hormone for a woman. Without it, she has an increased risk for a number of health issues, including: premature ovarian failure, osteoporosis, heart disease, colon cancer, Alzheimer’s disease, tooth loss, impaired vision, Parkinson’s disease and diabetes.
Woman have oestrogen receptors in a number of places throughout the body and brain. As a result, hormonal imbalance produces a variety of symptoms such as bone loss, mood changes, cognitive decline and loss of skin elasticity. When oestrogen levels rise, the amount of serotonin available in the brain increases, which improves mood.
The main forms of oestrogen found in a woman’s body are:
Oestrogen stimulates a girl’s development into a woman who is capable of reproduction. Oestrogen travels in the blood to body tissues where there are oestrogen receptors. Oestrogen receptors are found in a number of parts of the body.
When a woman’s oestrogen levels drop there are a number of negative effects. The end of menses is due, in part, to oestrogen levels that are too low to stimulate the lining of the uterus (endometrium).
Oestrogen loss can also cause:
What role does DHEA (Dehydroepiandosterone) play in the body?
DHEA functions as a precursor to male and female sex hormones, including testosterone and oestrogen. Precursors are substances that are converted by the body into a hormone.
DHEA production peaks in the mid-20s and, in most people, gradually declines with age.
DHEA supplements can be made from wild yam or soy. There have been some interesting studies supporting the positive anti-ageing effects of DHEA supplementation.
DHEA supplementation is believed to increase the level of testosterone and oestrogen, and can have benefits such as:
Pellets VS Creams - the format that suits you:
Bio-identical hormone pellet therapy
Estradiol and testosterone pellets have been in use in the United States since 1939. In the UK and the rest of Europe, pellets are standard menopausal therapy. Many South African gynaecologists recommend pellet therapy as an effective way of dealing with menopausal symptoms.
Bio-identical hormones are extracted from plants and molecularly structured to an exact replica of what the body produces. A small amount of the hormone is slowly released into the body every day for 3-6 months, depending on the pellet dose.
The pellets are about the size of a grain of rice and are inserted in a painless and quick procedure in the doctor’s office – no stitches are needed.
Pellets are compounded individually for each patient and the hormone levels need to be regularly checked to ensure that optimum levels are being achieved.
Bio-identical hormone creams
A doctor will prescribe the specific hormone dosage depending on the hormone test results and other health factors. Regular tests are required to ensure optimum levels.
The cream will release hormones into the bloodstream, which will provide relief for hormone deficiency symptoms.
Cream can be applied daily, as per the doctor’s instructions, either on the forearms, flanks, blushing areas or thighs. Vaginal application is also very effective.
On arrival, you will be asked to complete a confidential patient intake form.
Your practitioner will then discuss your concerns and requirements with you in order to get a clear understanding of your expectations.
You may have to fill in a hormone imbalance symptom questionnaire.
Blood will be drawn in order to test your hormone levels.
After a thorough examination, the most suitable treatment options and their alternatives will be proposed to you. Treatment procedures will be clearly outlined and discussed, together with the benefits and possible risks of each.
To ensure a good result, it is of utmost importance to carefully select our patients for this treatment.
Your practitioner may also provide you with a quotation.
Any questions you have about the process or treatment will be answered honestly.
Together, you and the practitioner will then decide on the treatment that is most appropriate and safe for you.
