Hacking your Hormone Health

Hormones are special chemical messengers in the body that control most bodily functions. The hormones that have the biggest impact are our steroid hormones. These include: oestrogen, progesterone, testosterone, DHEA and cortisol. Understanding these major hormones and what they do, can help us take better control of our health.

To begin, it is important to note that cholesterol (which is often made out to be the enemy) is the precursor to the production of our sex hormones. When cholesterol levels are depleted, due to poor liver function, or because of the use of Statin drugs, hormone production is disrupted. This puts individuals at a greater risk for, not only hormone dysfunction, but also for cognitive impairments, depression and certain types of cancers. In other words, we need to keep our hormones healthy if we want to function optimally. Now that we know some of the basics, let’s delve a little deeper and introduce you to your key sex hormones.

Oestrogen is not a single hormone; it is a group of hormones that play an important role in the development of men and women’s sexual and reproductive health. 

Which Hormones make up Oestrogens?

• Oestrone (E1): is an oestrogenic hormone secreted by the ovaries as well as adipose tissue. It is the main form of oestrogen in postmenopausal women.
• Oestradiol (E2): is produced by the ovaries using cholesterol and is the main oestrogen secreted before periods cease (menopause). It is also produced by the adrenal glands. It is responsible for building up the lining of the uterus. It is known as a strong oestrogen with a powerful effect on oestrogen receptors.
• Oestriol (E3): is a relatively weak natural oestrogenic hormone and is one of the metabolic products of oestradiol. It is the main oestrogen produced during pregnancy.

In women, oestrogen is produced in the ovaries, adrenal glands and fat cells. In men, it is produced mainly in the adrenal glands. Oestrogen can affect both men and women; however, it is largely responsible for female physical features and reproduction. Ladies, you may remember going through puberty and seeing your breasts develop, pubic and armpit hair grow and starting your menstruation cycle. This is a result of rising oestrogen levels. Whilst oestrogen is mainly involved in puberty and reproduction, it also affects the urinary tract, cardiovascular health, bones, breasts, skin, hair and even the brain. And that’s not all! Oestrogen also plays a role in:

• Formation of female secondary sex characteristics
• Acceleration of metabolism
• Reduction of muscle mass
• Increase of fat stores
• Stimulation of endometrial growth
• Increase of uterine growth
• Increase of vaginal lubrication
• Thickening of the vaginal wall
• Maintenance of vessels and skin
• Increase of bone formation
• Promotion of heart health

For many reasons, your body can make too much or too little oestrogen. One may even take in too much oestrogen via certain foods and medication. When this happens, hormones can become imbalanced and symptoms can persist.

Excess oestrogen, also called oestrogen dominance, can cause:

• Acne
• Depression
• Fatigue
• Fluid retention
• Loss of libido
• Low thyroid function
• Low progesterone
• Memory loss
• Migraine headaches
• Heavy and painful menstruations
• PMS
• Hot flushes
• Weight gain
• Insomnia
• Oestrogen dominant conditions such as: uterine fibroids, fibrocystic breasts, ovarian cysts, endometriosis and cancer
• Erectile dysfunction in men
• Breast growth in men

Do some of these symptoms sound familiar? What is most surprising is we put up with many of these symptoms, simply putting them down to our impending menstruation. However, in reality, they are just signs that our hormones are imbalanced.

Not only can you be oestrogen dominant, you can also suffer because of low levels of oestrogen.  Symptoms include: 

• Brain fog
• Painful intercourse
• Recurring urinary tract infections
• Vaginal dryness
• Thinning of vaginal wall
• Hot flashes and night sweats
• Infertility
• Low libido in men
• Excess belly fat in men

Brain fog, vaginal dryness and loss of libido are commonly associated with ageing. If that’s the case, please take me to the fountain of youth! Luckily, many of these signs are subtle or not-so-subtle indications that our hormones may not be functioning up to par, and there are tweaks we can make to overcome them.

The issue today is that we are bombarded by environmental oestrogens, also called xenoestrogens or oestrogen mimickers. These man-made chemicals act exactly like oestrogen in the body. When you have too much oestrogen, you are what is called oestrogen dominant.

Some of the most common female oestrogen dominant conditions are: premenstrual syndrome (PMS); endometriosis; abnormal Smear tests; ovarian cysts; cystic breasts; uterine fibroids; heavy periods; low thyroid; cellulite; hormonal acne; difficulty losing weight and severe menopausal symptoms. Ouf! In addition, women who take hormones in the form of the birth control pill or hormone replacement therapy can also become hormone overloaded if they are not being monitored properly, increasing their risks for serious health issues.

Xenoestrogen can be either synthetic or natural chemical compounds that are found in our food and environment including:

• Pesticides, herbicides and fungicides
• Parabens and phthalates (mostly found in cosmetics)
• Farmed fish, commercially raised meat and diary
• Birth control pills and hormone replacement therapy
• Coffee and alcohol
• Usage of microwaves
• Soy products

Essentially, every organ and tissue in the body has oestrogen receptors. When oestrogen circulates in the body it binds to oestrogen receptors and triggers certain effects in that organ or tissue. Xenoestrogen will mimic our natural oestrogen and attach to our oestrogen receptors, potentially taking the place of a real oestrogen molecule, or giving the cell the wrong signals. This disturbs our hormonal system and affects the entire body. Limiting exposure to these chemical oestrogen mimickers is key for optimal hormone function and optimal health.

Known as the “feel good hormone,” progesterone is produced in the ovaries and used in the production of our other sex hormones. Progesterone receptors can be found all over the body, including the brain, skin, thyroid, blood vessels, breasts and bones. An optimal level of progesterone is needed to ensure that these areas function properly. Progesterone is especially high during pregnancy, keeping the uterus from contracting until labour begins. It naturally decreases around menopause when the ovaries stop the production of eggs. However, small amounts are still produced in the adrenal glands. In men, progesterone is converted into testosterone and DHEA.

How will you know if you have too much or too little Progesterone?

Symptoms of excess progesterone include:

• Breast swelling and pain
• Depression or low mood
• Growing facial hair
• Fatigue, drowsiness
• Overproduction of insulin
• Low libido
• Oily skin
• Developing brown spots on skin

Symptoms of low progesterone include:

• Anxiety or difficulty handling stress
• Craving carbs
• Elevated cortisol
• Oestrogen dominant conditions
• Headaches
• Headaches
• Heavy periods
• Infertility
• Osteopenia and Osteoporosis
• Recurrent miscarriages
• Water retention
• Weight gain around abdomen
• Insomnia

Testosterone, although known to influence male sex drive and aggression, also plays an important role in female hormone health. It is crucial for women’s sex drive, muscle tone, bone health, skin and cardiovascular system. In women, testosterone is produced in the ovaries but most is converted into oestradiol.

Symptoms of low testosterone are:

• Tiredness
• Weakness
• Mood swings and depression
• Change in sleep habits
• Increase body fat and decrease muscle mass
• Low sex drive
• Erectile dysfunction for men
• Weight gain
• Anxiety
• Hair loss

Symptoms of high testosterone are:

• Well-being (reduction in depression and mild euphoria)
• Confidence (reduced social anxiety and greater assertiveness)
• Better energy
• Greater sex drive and libido
• Greater concentration and focus
• Body fat reduction and increase muscle mass
• Polycystic ovarian syndrome (PCOS) in women

Women on high doses of oestrogen supplementation (HRT) may also have an increase in sex-hormone-binding, globulin (SHBG), which is a blood protein that reduces the amounts of free testosterone as SHBG. This has a higher affinity to bind to testosterone than oestrogen; therefore, reducing the amount of testosterone available.

Testosterone and Aromatase

Aromatase is a naturally occurring enzyme located in multiple tissues in the body. In men, it is located in the brain, muscles, and testicles. In women, it is located in the ovaries, placenta, and lining of the uterus. It is the enzyme responsible for converting testosterone into oestrogen and it has been found to increase the amount of fat an individual has. Poor nutrition and weight gain are a common cause of increased aromatase activity. In addition to this, high stress levels, lack of exercise, chronic inflammation and insulin dysregulation can also contribute to aromatase activity. Certain foods are known as aromatase inhibitors. These foods include: flax seeds, resveratrol, green tea extracts, quercetin, iodine, mangosteen extracts and isoflavones to name a few.
