Hormones are chemical messengers that affect the way your cells and organs function. It’s normal for hormone levels to fluctuate over time, such as with your monthly cycle, during pregnancy, or with the onset of menopause.
For women, the most pronounced hormonal changes come in the 40s and 50s, but are also seen in the mid-30s. Hormonal changes not only progress with age, but are also linked to lifestyle, diet, medications, pollution, toxins and xenoestrogens (synthetic chemicals that act as oestrogen in our bodies) that we are exposed to every day.
Hormonal imbalance can be to blame for a long list of symptoms which include irregular periods and infertility, cravings and persistent weight gain, digestive problems, low libido and vaginal dryness, fatigue, anxiety, irritability and depression, insomnia and poor sleep patterns, chronic acne and night sweats
A simple oestrogen and progesterone test can identify a hormonal imbalance. Changes to diet, digestive health, stress management, improved sleep and consistent physical activity have been shown to be effective in managing the effects of hormone fluctuations.
*Note this test is not appropriate if you are taking oral contraceptives.
This hormone analysis includes an oestrogen, testosterone and progesterone test, as well as an LH and FSH test. These sex hormones (in conjunction with adrenal and thyroid hormones) exert powerful effects on the body. Knowing the function and levels of these hormones is a positive step in creating hormone balance and achieving wellbeing.
Too much oestradiol (oestrogen) is linked to acne, constipation, loss of sex drive, depression, weight gain, PMS, period pain, and thyroid dysfunction. The effects of low oestradiol are evident in menopause and include mood swings, vaginal dryness, hot flashes, night sweats and osteoporosis.
The sex hormone produced mainly in the ovaries following ovulation and is a crucial part of the menstrual cycle. Progesterone helps to combat PMS and period pain issues, assists fertility and promotes calmness and quality of sleep.
Governs the menstrual cycle, peaking before ovulation. Raised LH can signal that a woman is not ovulating, is menopausal or that the hormones are not in balance. A high LH/FSH ratio can indicate Polycystic Ovarian Syndrome (PCOS).
Stimulates the ovary to mature an egg. High levels indicate poor ovarian reserves which means the quality and quantity of eggs may be low. This doesn’t necessarily mean that pregnancy is impossible, but it may be more difficult to achieve.
Normally this ratio is about 1:1 meaning FSH and LH levels in the blood are similar. In women with polycystic ovaries the LH to FSH ratio is often higher e.g. 2:1 or even 3:1
High levels inhibit secretion of FSH and interfere with ovulation, and can also inhibit the production of progesterone which is needed to prepare the lining of the uterus for implantation of an embryo.
High levels commonly seen in polycystic ovarian syndrome (PCOS) which can lead to difficulties in conceiving. Symptoms can include irregular periods, loss of hair from the head, excess facial and body hair, unexplained weight gain and acne.
Most testosterone is strongly bound to sex hormone binding globulin (SHBG). This test measures the proportion of unbound testosterone which is available to the body's tissues.
Sex Hormone Binding Globulin (SHBG) is a protein that binds tightly to testosterone and oestradiol. Changes in SHBG levels can affect the amount of hormone that is available to be used by the body's tissues.

Take test 7 days before predicted date of menstruation (if known). If menstrual cycle is 28 days, test on day 21 (where day 1 is the first day of bleeding).
