MENOPAUSE

About Menopause
Menopause is the end of a woman's reproductive life, when a woman goes a full 12 months without the occurrence of a menstrual period, the ovaries cease producing eggs, and the body stops making the hormones oestrogen and progesterone.
​
There are a wide range of symptoms associated with menopause, both physical and emotional, including: hot flashes, night sweats, arthralgia, vaginal dryness, urinary symptoms, insomnia, forgetfulness, difficulty concentrating, feelings of anxiety or irritability, and mood swings.
​
Menopause can be spontaneous or induced. Chemotherapy and radiotherapy treatments can stop the ovaries from functioning, and induce menopause. Surgery to remove both ovaries also induces menopause. Sometimes ovaries are surgically removed to treat endometriosis, pelvic inflammatory disease, or ovarian cancer.
​
Natural onset of menopause generally occurs between ages 45-55, with the average age being 51, however it can occur earlier, as in the case of:
-
Early menopause - onset prior to 45 years of age
-
Premature menopause - onset prior to 40 years of age
Spontaneous premature ovarian failure affects 1% of women by age 40 and 0.1% by age 30*.

The Transition
The menopausal transition is unique for each woman and can vary in duration from a few years, to more than a decade. Managing the transition can be made easier by understanding the stages of menopause, identifying where in the transition you're at, and what to expect on each leg of the journey.
stages of menopause
There are 3 main stages of menopause:
Perimenopause, menopause, and postmenopause.
​
Perimenopause
Also called the Menopause Transition, perimenopause is the beginning of the transition into menopause. This lasts on average 4-6 years, but can last as short as one year, or as long as ten years. As the ovaries begin to run out of eggs, hormone levels, particularly oestrogen, can swing erratically from high to low.
The pituitary gland produces higher levels of signalling hormones – follicle-stimulating hormone (FSH) and luteinising hormone (LH) – to the ovaries in an effort to keep the ovaries producing eggs and oestrogen levels normal. During this time, ovulation (the release of an egg) might occur twice in a cycle, the second time during a period. This can lead to very high hormone levels. In other cycles, ovulation might not occur at all.

​
As ovulation continues in perimenopause, it is possible to fall pregnant during this stage, hence contraception should still be used if pregnancy is not desired.
​
MENOPAUSE
The word menopause refers to the final menstrual period, denoted by the absence of menstrual periods for a full 12 months.
​
Postmenopause
This stage begins when menstruation has not occurred for 12 months. On average lasting between 2-6 years, postmenopause is characterised by lower hormone levels, which may cause hot flashes, night sweats, palpitations, headaches, insomnia, fatigue, bone loss, vaginal dryness. Lower hormone levels also increase your risk for related diseases like osteoporosis and heart disease.
​
Self Care
Whilst self care is important at any stage of life, when embarking on menopause, it is a key component of setting up for a positive attitude and mindset with with to enter this phase of the journey. Making time for yourself: setting aside time for activities you find relaxing and enjoyable, and embedding these regularly into your routine can ensure your menopause experience is primarily a positive and empowering one. Staying connected with friends, and surrounding yourself with good people assists in creating a network of support that will have a lasting positive influence on your energy and well being.
NUTRITION
Maintaining a nutritious diet, and regular moderate exercise can enhance your well being and assist in optimising your health through this new life phase. Bear in mind your body's changing dietary needs: a diet rich in calcium and vitamin D is important to prevent the bone loss that can occur during menopause. Lower oestrogen levels associated with menopause also increase the risk of cardiovascular disease, so aim for a diet rich in omega 3 and fibre: fruits and vegetables, whole grains, nuts and oily fish; and limit foods such as red and processed meats, refined carbohydrates, foods and beverages with added sugar, sodium, and trans fats.

Treatment Options
Women seeking treatment for menopause should ascertain whether they wish to take medication, hormone therapy, or use natural and alternative remedies.
Menopause is a unique experience for all women and a range of management options is available for the different symptoms, including:
​
-
healthy living
-
menopausal hormone therapy, or MHT (formerly called hormone replacement therapy, or HRT)
-
treatments to manage vaginal dryness
-
non-hormonal prescription medications
-
complementary therapies
-
pharmacy-compounded hormone therapy (not recommended).

Some treatments are well supported by valid scientific research; others have less evidence to support their use. It is important to have accurate and reliable information before you start any treatment.

MHT
Menopausal hormone therapy (MHT) was previously known as hormone replacement therapy (HRT). It contains oestrogen plus a progestogen, or oestrogen alone for women who have had a hysterectomy (an operation to remove the uterus)

​
During Menopausal hormone therapy, the hormones can be administered via tablet, patch or gel form.
There are risks associated with MHT depending on the combination of hormones taken. Oestrogen alone can increase the risk of endometrial cancer. Combined MHT can result in slightly increased risk of:
-
Breast cancer
-
Thrombosis
-
Stroke
-
Gallstones
-
Endometrial cancer
​
Natural remedies
Soy
Soy contains plant based oestrogens called phytoestrogens. These have a similar chemical structure to the hormone oestrogen, and are able to bind to the same receptors in the body that our own oestrogen binds to. These phytoestrogens are in the form of isoflavones including: genistein, daidzein, glycitein, formononetin, and biochanin. Increasing consumption of these isoflavones may assist in improving menopausal symptoms.
Trials found that extracts of 30 mg. or greater of genistein consistently reduced the frequency of hot flashes.

Note: the effect of soy can vary depending on the level of existing natural oestrogen in the body. Soy may act as an anti-oestrogen whereby higher natural oestrogen levels exist.

Herbal medicines
-
Black cohosh - may have a mild benefit for hot flushes in some women.
-
St John's wort - may improve depression but has not been shown to improve menopausal symptoms. St John’s wort may interact with other medications so check with your doctor before taking it.
-
Evening primrose oil, dong quai, ginseng, licorice and sage do not reduce menopausal symptoms.
