Estrogen dominance and your thyroid, the common signs & symptoms

Estrogen dominance and your thyroid, the common signs & symptoms

Heavy periods, hormonal issues, migraines, mood swings, weight gain…. are you estrogen dominant ? 
Or do you have an underactive thyroid ………or both?
Estrogen dominance is common in women of all ages, but can also be a problem in perimenopause ad menopause.
Progesterone drops rapidly during perimenopause which can make you estrogen dominant .
Estogen and progesterone need to be in a certain ratio.
As your ovaries start shutting down, we release less eggs and ovulate less. Which means progesterone drops. This can be exacerbated by stress and high cortisol ( stress, lack of sleep, inflammation)
Estrogen is produced by the ovaries in reproductive years, and in menopause the fat tissue, muscle, DHEA from the adrenal glands .
It can be re-absorbed through the digestive system and women become dominant in estrogen when they are clearing the excess properly.
Excess estrogen slow the thyroid function down and contributes to a underactive thyroid.
The symptoms you may experience when you have a sluggish thyroid may include-
• Fatigue
• Weight gain
• Hot flushes
• Insomnia
Causes of estrogen dominance-
• Poor liver function
• Gene polymorphisms (MTHFR and COMT)
• Poor gut elimination
• Low thyroid function
• Exposure to xeno-estrogens
• High histamines – allergies or in foods. (more sensitive through menopause)
Some signs of Estrogen dominance
  • underactive thyroid
  • weight gain esp. hips and thighs
  • cellulite
  • moodiness
  • fatigue
  • heavy bleeding during your menstruation
  • migraines and headaches
  • foggy head
  • fibroids
  • fluid retention
  • PMS/ PMT

Your gut bacteria and your hormones

Your gut bacteria and your hormones

An endocrine gland is a hormone producing gland such as the ovaries and adrenals.
Your gut bacteria helps produce-
  • Estradiol – the protective estrogen
  • 90% of Serotonin production ! Serotonin is one of your happy hormones and its also regulates appetite, sleep, mood and temperature .
Your gut bacteria regulates
  • Melatonin - which regulates our circadian rhythm and sleep cycle
  • Dopamine – all about rewards / addictions
  • Grehlin – your hunger hormone, if your gut bacteria is off you will eat more!
Your gut bacteria
  • Metabolise & excretes bad estrogens
  • Increase stress hormones (adrenaline & nor-adrenaline)
  • Influence your thyroid hormones & thyroid stimulating hormone (TSH)
The gut bacteria regulates estrogens through an enzyme called beta glucaronidase.
This enzyme keeps the ‘bad’ estrogens low in the body and protects you from estrogen dependant cancers.
An alteration in circulating estrogens may contribute to estrogen dominant states.
Estrogen dominant states include
  • Obesity
  • Metabolic syndrome
  • Cancer
  • Endometrial hyperplasia
  • Endometriosis
  • Fibroids
  • Polycystic ovary syndrome
  • Infertility
  • Cardiovascular disease (CVD)
  • Cognitive function decline
Your gut bacteria produce enzymes called the ESTROBOLOME. Your estrobolome controls your estrogen metabolism and excretion.
If your estrobolome is unhealthy, you become estrogen dominant and more prone to the ‘bad’ estrogens affecting your health.
One definition of the Estrobolome is –
“…the aggregate of enteric bacterial genes whose products
are capable of metabolizing estrogens”
“By modulating the enterohepatic circulation of estrogens, the estrobolome affects both the excretion and circulation of estrogens. In turn, the composition of the estrobolome can be shaped by factors such as antibiotics, other drugs, and diet that modulate its functional activity.”

Plottel SC, Blaser MJ.
A healthy Oestrobolome in the gut helps the body excrete estrogen appropriately !
To have happy hormones you need to get your gut right!!
🥑A poor diet, antibiotics, toxins/chemicals, and alcohol worsen your microbiome thus potentially increasing estrogen
🤢Constipation will cause hormone imbalance due to poor excretion of toxins and bad estrogens.
🥦Prebiotics and probiotic supplements and foods are your friend.
🥕A diet rich in plant fibres improves your gut microbiota!

The gut-hormone connection

The gut-hormone connection


Did you know that your gut bacteria or flora help regulate your hormones, especially estrogen?

Your gut microbiome has far reaching effects.

Signs of a gut - hormone imbalance are




• Stomach/ digestive upset

•Constipation or IBS


•Gut infections


•Heavy, light, or irregular periods

•Hot flashes

•Low libido

•Mood swings

•Polycystic ovarian syndrome (PCOS)


•Tender, swollen, and/or fibrocystic breasts

•Weight gain

If  your gut isn’t healthy then your hormones are not going to be healthy.

An unhealthy gut means estrogen is not metabolised properly and the is can build up in the body and may contribute to estrogen dominant states. This can further lead to more serious condtions such as obesity, metabolic syndrome, cancer, endometrial hyperplasia, endometriosis, fibroids, polycystic ovary syndrome, fertility, cardiovascular disease (CVD) and cognitive function. (1)


The estrobolome is a collection of these gut microbes that work to metabolise (process / breakdown) estrogens. These microbes produce an enzyme called betaglucaronidase, that switches on estrogen, so it becomes active in the body,

When you have a healthy estrobolome, it will produce the right amount of betaglucaronidase to balance your estrogens. If you have too much betaglucaronidase (which can be caused b the bad gut bacteria), it will increase your estrogen too much. This is associated with estrogen dominance and estrogen dominant conditions, such as heavy and painful menstruation, endometriosis and fibroids.

‘High levels of circulating estrogens from overactive beta-glucuronidase activity could promote cell growth and tumor growth on estrogen-sensitive tissues in the breasts, ovaries, endometrium, and the cervix.’ (2)

When you dont have enough betaglucaronidase it will lower estrogen and reduce the amount of good gut microbes and is linked polycystic ovarian syndrome, cardiovasclar disease, weight gain and osteoporosis.

To improve your Estrobolome balance you can

  • Eat an organic, whole food diet
  • Increase your veggies, especially broccoli and deeply coloured veggies
  • Reduce processed foods and sugar
  • Eat broccoli sprouts or take sulforaphane
  • Reduce or avoid coffee and alcohol
  • Take probiotics and prebiotics in supplements or food
  • Exercise (this increase butyrate, which boosts good gut microbes and reduces inflammation!
  • Reduce endocrine disruptors (ie- plastics, parabens, BPA etc)

Getting you gut right will go a long way to help balance your hormones!

If you are not sure what state your gut is in, or what your betaglucaronidase levels are, you can get tested. If you would like to know how , or need support on your healing journey, please contact me HERE

Are you exhausted? Fatigued? Overwhelmed? Anxious? Moody? Depressed ? Wired and tired at night? Are you getting sick all the time or constant hay fever or allergies ?

If you have any of these symptoms, fatigue on waking or throughout the whole day and you have been suffering long term, your adrenal glands are probably to blame. These small, walnuts sized glands produce our ‘fight or flight’, or stress hormones. They therefore help regulate the stress response, but also other hormones, the nervous system, cardiovascular system, regulate the sleep wake cycle and inflammation, and the immune system. With many people in today’s busy world, they get over worked and then they cannot keep up with the ongoing demands our bodies put on them.

To rebuild the adrenals, you should avoid all stimulants where possible. This includes caffeine in chocolate, coffee, cola and guarana in supplements, sugar, alcohol, and white flour products/ refined starches. Reduce stress and get plenty of sleep.


  • Eat within 2 hours of waking up
  • Eat frequently through the day to regulate your blood sugar levels, at least every 4-5 hours. This will prevent a drop in your blood sugar levels and will make a difference to your adrenal health and energy levels.
  • Eat good quality protein at every meal. These can include organic free range eggs and chicken, fish and nuts and seeds.
  • Eat a wide variety of whole, natural foods
  • Combine a healthy fat, protein and carbohydrate source with every meal
  • Eat lots of vegetables, especially the brightly coloured ones and preferably organic
  • Use a mineral salt such as Celtic sea salt or Himalayan salt; ½ a teaspoon daily.
  • Avoid fruit in the morning
  • Mix 1-2 tablespoons of fresh essential oils (cold pressed olive or flaxseed oil) into wheat free grains, vegetables and meats daily. Do this after cooking as they are not meant to be cooked with! Cook with coconut oil which is anti-inflammatory and has a high burning point.


Magnesium is a very important mineral for adrenal gland function. It is estimated that at least 80% of the population are magnesium deficient. Please be aware that there are many forms of magnesium and they are not all the same! Practitioner ranges have the most bio-available forms, meaning they are very efficiently absorbed. Potassium and magnesium together are the ‘nervous system Nutrients’.

B complex vitamins are important but may be too stimulating for some people when they are extremely adrenally fatigued. In these cases, magnesium, potassium and vitamin C are the best nutrients to nourish the adrenals glands.  ‘Activated’ B vitamins should be used for more efficient absorption.  Vitamins B5 and B6 especially help to restore adrenal function. Always take a B- complex if you are taking singular B vitamins to avoid an imbalance occurring. Be careful during intense anxiety as the B vitamins maybe too stimulating, also when there is Chronic fatigue, take small amounts to begin with and see how you feel.


There are many herbs for the adrenal glands that can help strengthen the adrenals, but also act as adaptogens. Adaptogens help your body adapt to stress and protect the adrenals from any ongoing stressors. An example of an adaptogen are; siberian ginseng, panax ginseng, withania and Rhodiola. Withania can help when there is insomnia and Rhodiola is great for energy, stamina and cognitive function.  I use other herbs simultaneously to strengthen the adrenals glands, such as Rehmannia and licorice, along with homeopathics.

When there is anxiety, herbs such as withania, skullcap, magnolia and ziziphus, are great to reduce the flight and fright hormones. It is important to check your Thyroid function through a basal body temperature testing or a thyroid function test. The thyroid gland may need support also. The adrenals and thyroid work together to help regulate the nervous system.


The adrenals cannot rebuild themselves when they continually stimulated. It’s like whipping a dead horse! If you are tired, avoid ‘soldering on ‘, as this will only make the adrenals weaker. De- stress often, by meditating or doing yoga or Tai chi. Have regular massages and enjoy some time to yourself every day. During times of anxiety more intense exercise may be needed to help the body rid the stress hormones and relieve tension.

Have an Epsom salt bath before bed to get you into a deeper sleep. If you haven’t got a bath, have a warm shower and afterwards rub some lavender oil on your temples. Magnesium oil can be rubbed on the tops of your feet before bed to give the same effect as the Epsom salt bath (Epsom salt is magnesium). Sleeping well and for at least 8 hours a night is an integral part of helping the adrenals recover.


Try and practice breathing from the lower part of your diaphragm. Too many people shallow breathe when they are stressed or have anxiety. Breathe in for a count of 3, and out for a count of 5, when you feel anxious or finding it hard to get to sleep.

Also our adrenals are patterned from birth, we pick up stresses in utero (the womb) and during childhood, which can have long term effects on our adrenal glands. In families, there may be a genetic pattern, where the all of family members have a similar weakened adrenal response.

No matter what stage you are in, there IS a sure road to recovery!  I am here, to help you recover also!

1; an excerpt From Angela Hywood on ‘The Adrenal insufficiency syndrome’

NLS Salivary hormones training manual, 2009




Stress comes in many forms. It can be emotional (ie; relationship issues at work and home, grieving ), physical (ie; overwork, over exercise, over sedentary )and environmental (ie; hay fever, chemicals, pollution). When your body is under constant stress, such as being busy. working too hard and not sleeping well we are usually in the continual ‘fight or flight’ response. We produce more cortisol than usual, a hormone produced by our adrenal glands.

High cortisol over time reduces progesterone levels. This is because we produce cortisol and progesterone from the same hormonal precursor- pregnenolone. Progesterone is our anti-anxiety hormone and gives a feeling of contentment. And if you feel like you have constant PMT/PMS then you probably are low in progesterone!

If this keeps dropping over time because of stress, lowered thyroid function or a sluggish liver, then you end up with estrogen dominance. Excess estrogens can cause more frequent, painful and heavier periods, slow down the thyroid function and contribute to an under active thyroid.

And when the thyroid function slows down, this slows the liver function down and it becomes a cycle. Prolonged cortisol levels also can decrease the livers ability to clear excess estrogen from the blood.

A sluggish liver can mean you end up with insulin resistance and weight gain. Insulin is the hormone which ‘unlocks’ glucose from your food. If you are not unlocking the glucose for energy, it is stored as fat in your body, usually abdominal fat after age 40, which I known as the middle-aged spread…. Eeek! I know no-one really want this to happen!

Also, as we age we become more resistant to insulin, this can cause weight gain. Our body doesn’t utilise glucose from food as efficiently as it did when we were younger. The way around this is to exercise more and eat less sugar and carb’s.

All the endocrine glands and hormones work together like an finely tuned orchestra, so when one hormone is out of wack it will inevitably effect the others.
But don’t let this be you! You can change it, naturally .
