Is it the Menopause?

Officially menopause is when you’ve gone for 12 months without a period at all which signifies the end of female reproductive capabilities.  However, most symptoms occur in the 2-10 years leading up this – which is known as perimenopause.

Unfortunately, there's no specific blood test for perimenopause. And this is where a lot of confusion starts to arise. Many of my clients have odd symptoms which send them to the GP, only to realise a couple of years later that it was probably perimenopause…

I often use the DUTCH test, a dried urine test, which can be very useful in looking at a complete balance of sex and stress hormones during this turbulent time. While testing hormones during perimenopause and menopause is not often done in conventional medicine, understanding hormone levels and their metabolism (as well as assessing our stress levels) can help guide recommendations to support women during this stage in their life. Do get in touch with me if you’d like to discuss this further.

But what are the symptoms of perimenopause?  Because our hormones affect our whole bodies, not just our sexual characteristics, perimenopause can bring a whole heap of symptoms with it, such as:

  • Increased allergies/intolerances
  • Anxiety
  • Bloating & other digestive problems
  • Increased body odour
  • Brain fog
  • Chills
  • Depression or low mood
  • Fatigue
  • Forgetfulness
  • Gum problems
  • Headaches
  • Heart palpitations
  • Hot flushes/flashes
  • Irregular periods
  • Increased irritability
  • Itchy skin
  • Joint aches & pains
  • Low sex drive
  • Osteoporosis
  • Pain or bleeding during sex
  • Panic attacks
  • Pins & needles
  • Night sweats
  • Sleep disturbances/ insomnia
  • Sore boobs
  • Thinning/ dry hair
  • Urinary incontinence
  • More UTIs (like cystitis)
  • Vaginal dryness
  • Weight gain

(Please note: some of these symptoms may not be perimenopause – so if you’re worried, do check with your GP!).

When and how we suffer tends to be based on a combination of genes, our health, and our environment. If you can, it might be good to ask your mum when she had hers and how it affected her. But, overall, it’s one helluva time. No wonder it’s sometimes called second puberty.

Most of the symptoms we have are due to fluctuating oestrogen and intermittent progesterone, brought about by the natural retirement of our ovaries.

Why is oestrogen so important?

Well, we have receptors to oestrogen all over our bodies – they’re not just responsible for the reproductive cycle.  They are found in our brains, bones, guts – just about everywhere. 

Oestrogen helps us build muscle, regulates bone density, and promotes healthy skin. It helps maintain healthy brain function. It looks after our heart and cholesterol levels. And it even has a hand in our gut function. But probably most noticeably is abdominal weight gain or ‘menobelly’. This is where we start to gain weight around our middles that we possibly didn’t have before, and it’s now more difficult to get rid of too. 

So, how do you know if you’re in menopause?

As a rule of thumb, we can tell that it’s probably perimenopause if you’re having:

  1. Irregular cycles with no other possible cause


  1. If you’re still cycling but have any three of the following nine changes:
  1. new-onset heavy and/or longer periods
  2. shorter menstrual cycles ie 25 days or less
  3. new sore, swollen or lumpy breasts
  4. new waking during the night
  5. increased menstrual pain
  6. onset of night sweats, particularly in the lead up to your period
  7. new or increased migraines
  8. new or increased PMS
  9. unexplained weight gain 

If you’re still not certain, check in with your GP or nurse, or book in a free call with me here at the clinic.

Food to Fix Your Hormones


What are they and why you need them.

When it comes to diet, food is so much more than macronutrients like protein, carbohydrate and fat. And even more than the sum of its vitamin and mineral content. Some of the magic ingredients the nutrition world is talking about are phytoestrogens.

These are naturally occurring plant-based chemicals, which are structurally similar to oestrogen and exert a weak oestrogenic effect. The great news is that you can use them to gently help rebalance your hormones.

Phytoestrogens are particularly helpful for women because they are adaptogens. This means they can either replicate or counteract the effects of oestrogen. They’re useful for all women but especially if you are going through the perimenopause, have endometriosis, fibroids or PMT (any symptoms at all during or in the run up to your period).



This is a stage in a woman’s life usually starting in her late 40s. During this time, your body stops making as many female hormones like oestrogen. This transitions into a time when your periods have stopped for at least 12 months – menopause. There are many uncomfortable symptoms that usually occur during this phase of your life, ranging from hot flushes and mood swings to decreased libido. Research shows that phytoestrogens can have a positive impact on many of these symptoms.

Bone health

Oestrogen plays an important role in maintaining bone mineral density. Osteoporosis is a disease in which bone density and quality is reduced, resulting in greater porosity of bones and a higher risk of fracture. Research is ongoing in this area but the work shows that a diet that brings these phytoestrogens into your life may help prevent osteoporosis.

Menstrual irregularities

Many menstrual problems are linked to too much oestrogen in your system – like endometriosis and fibroids. Phytoestrogen-rich foods decrease the effects of oestrogen levels naturally by blocking the oestrogen receptors on the cells in fibroids and other oestrogen-sensitive tissues.


Adult acne can result from an imbalance in hormones, often where male hormones like testosterone are present in a higher than normal ratio compared with oestrogen. The idea is that these plant sources of oestrogen counteract the effect of the male hormones and may help prevent acne as a result.

The Power of Food

While synthetic oestrogens (think HRT) have been linked to unfavourable outcomes like increased risk of some hormone-driven cancers, there are no known health risks from eating more plant foods.

Phytoestrogens and the gut

The absorption of phytoestrogens depends on a healthy gut, as there must be enough healthy bacteria to convert phytoestrogens into their active form. A probiotic supplement will be helpful here.

Phytoestrogen-rich foods:

The three types of phytoestrogens are isoflavones, lignans and coumestans


Soybeans (and related products like tofu, tempeh, miso)

Edamame beans


Beans (blackbeans, aduki beans, broad beans, pinto beans)


Split peas






Sesame seeds

Sunflower seeds

Pumpkin seeds




Brussels sprouts














Split peas

Pinto beans


Soybean sprouts

Is histamine intolerance causing your symptoms?

What you eat and your health are a fantastically complicated puzzle. For so many reasons linked to modern living, some foods can disagree with you. You may already experience this directly. People with digestive problems can often point to specific foods causing upsets and, if you think you have a food intolerance, you might already suspect wheat, dairy, yeast, eggs, or any number of foods to be the culprit lurking behind your symptoms. 

There’s one often-overlooked component found in some foods that you might not know about yet that I want to talk about today. Could it be this that’s causing you problems?

Histamine…too much of it for your body

If you have an allergy, you might already know about histamine since you probably take antihistamines to try to neutralise the effect is has on the body. Histamine is a signalling molecule that has a lot of roles in the body like making stomach acid and keeping you alert. It is also involved in the immune response and protects you from foreign invaders. 

When your immune system spots a potential invader, one type of immune cell (your B cells) to make IgE antibodies and these are a bit like warning signals to other immune cells to tell them to be on alert. When they meet the ‘invader’, other immune cells (this time your mast cells and basophils) throw out histamine and other inflammatory chemicals to neutralise the attack. 

This works really well for some types of invader - like parasites, as an example – but not so much when the system overreacts to harmless substances like peanuts, pollen, animal hair.  Welcome to the common allergy. It’s a histamine thing. And, if you have an allergy, you might be well used to antihistamines that can block or dampen the effect of this kind of allergic response.

If you’re reading this thinking, this doesn’t concern me as I don’t have an allergy, here’s why you should be interested. Histamine can be a problem for many other people – especially women since there is a big link between oestrogen and the cells that release histamine. 

Histamine symptoms tend to track with your menstrual cycle, peaking when oestrogen is at its highest and then again before your period. If you experience any of these symptoms, histamine could be the culprit:

  • Headaches
  • Brainfog
  • Bloating and digestive discomfort like pain or diarrhoea
  • Insomnia
  • Runny nose or congestion
  • Itchy eyes
  • Hives
  • Flushing
  • Dizziness

This is because oestrogen stimulates the mast cells to make histamine while at the same time downregulating an enzyme called that breaks down histamine, diamine oxidase (DAO). As a triple whammy, histamine triggers the ovaries to make more oestrogen. This can result in oestrogen dominance, where oestrogen is present in the wrong ratio to other hormones.

Histamine problems can also be a feature of perimenopause due to erratic release of oestrogen. Although oestrogen levels are dropping rapidly, progesterone falls faster, leaving oestrogen unopposed. 

Why do some people suffer, and others don’t?

  1. Genetics. Some people do not make enough of the histamine-clearing enzymes. 
  2. SIBO – or Small Intestine Bacterial Overgrowth, as this impairs DAO activity.
  3. Any conditions of oestrogen excess like fibroids and endometriosis or progesterone deficiency
  4. The birth control pill – this can cause both oestrogen excess and progesterone deficiency
  5. Vitamin B6 deficiency – this vitamin is needed to make DAO
  6. Certain medications - antibiotics, antidepressants, medication given for high blood pressure and heart rhythm problems, among many other common drugs like ibuprofen, aspirin and diclofenac.  

Dealing with histamine problems

One of the things you can do to manage histamine problems is reducing foods that either contain histamine or are ‘histamine liberators’. 

Which foods contain histamine?

  • Red wine and champagne 
  • Aged cheeses
  • Pickled and fermented foods, including ketchup, soy sauce and vinegar
  • Processed deli meats like ham, salami, bacon
  • Smoked or canned fish
  • Shellfish
  • Aubergine
  • Avocado
  • Spinach
  • Dried fruit
  • Bananas
  • Bone broth and fish stock
  • Left overs!

These foods, while they don’t contain histamine, trigger the release of histamine:

  • Citrus fruit
  • Chocolate and cocoa
  • Tomatoes
  • Egg whites
  • Fish
  • Peanuts

And alcohol and black or green tea interfere with the enzymes needed to break down histamine. 

Improving your gut health is always worth doing since do much of your health relies on a healthy gut. If you’ve been ignoring symptoms, especially if you think you have irritable bowel syndrome (IBS), we should talk. Getting your digestive system back into balance pays dividends for all aspects of your health.

Inflammatory foods like gluten, dairy, sugar and processed foods make the situation worse, encouraging the body to release inflammatory cytokines and histamine.

At the same time, increase anti-inflammatory foods. An easy way to do this is to add herbs and spices into your cooking. Particularly helpful ingredients include ginger, thyme, oregano, basil, chamomile, and turmeric

Support oestrogen detoxification by eating plenty of cruciferous veggies like broccoli, cauliflower, cabbage, Brussels sprouts

If you experience any of the symptoms I’ve talked about here, please do get it touch. It’s very easy to read things like this or take advice from Dr Google and end up following a very restrictive diet when this is not always necessary. Working one-to-one with a nutrition professional means that you can take advantage of their years of study to find a programme that helps support your health without overly restricting what you eat. It’s a minefield out there!

Here are my top five nutrition tips for helping to balance your hormones

  1. Eat real food

If your hormones are out of whack or you struggle with anything to do with your mood, the very first thing to do is to take a good look at your diet and consider how much ‘real food’ you eat and how much of your diet is processed. If you switched to ONLY real food, making everything from scratch, you would see a big improvement in your health. Ready to do more?

  1. Bring in more fruit and vegetables

Fruit and vegetables are packed full of nutrients compared to many other foods and are beneficial for all aspects of health. Focus on the low-sugar fruits (the ones that grow in this country ahead of tropical fruits like bananas, mango and pineapple). For veg, eat more of the stuff that grows above the ground as – as a general rule – it contains less starch and keeps blood sugar levels stable.

  1. Eat protein regularly

Choose a good source of protein at every meal and snack. Protein is needed for growth and repair in the body. Good sources of protein include eggs, organic meat and poultry, oily fish like wild salmon, trout, etc. and Greek yoghurt, nuts and seeds.

  1. Think carefully about starchy carbohydrates

Carbohydrates can be broken down into simple carbs and complex carbs. In simple carbs, the sugar molecules that occur either naturally or as a result of added sugar are quickly digested and absorbed into the bloodstream. Examples of simple carbs are cakes, cookies and pastries (in fact, anything with sugar), white bread, rice and pasta, and potato. The result is you get a short-term high but afterwards you feel more tired, fuzzy-headed and hungry. Complex carbs are made up of hundreds of sugar molecules, and these are absorbed much more slowly so they keep you feeling fuller and focussed for longer. Focus on bringing more of these into your diet ahead of simple carbs. They include brown rice, oats, beans, chickpeas and lentils, quinoa, sweet potato.

  1. Do eat fat

Healthy fats are an essential part of a good diet and should not be seen as the enemy. Fats are also the building blocks of all hormones and keep cell membranes and nerve cells healthy. The best sources of fat are flaxseeds (also known as linseeds), avocado, olive oil, coconut oil, oily fish like wild salmon, nuts and seeds.

And don’t forget about sleep, movement, and stress relief when you’re looking at hormones! These are just as important as nutrition. If you’d like to know more, why not get in touch and see how I can help you.

When you think about mental health, you’re probably thinking about your brain and how that works. The picture is often much more complex. Hormones play a big part because these chemical messengers are the background to everything that happens in your body. How you feel, therefore, is not just psychological, it’s biological.

Did you know, there are a huge number of symptoms that are common to both depression and hormonal imbalance? These include low energy, dizziness, low mood, apathy, anxiety, irritability, anger, lack of enthusiasm, despair, headaches, poor concentration, feelings of hopelessness, lack of confidence, low libido, fuzzy brain, memory loss, and insomnia (although there are others).

Rebalancing your hormones naturally is not something that happens overnight, but it can be greatly improved with the help of nutritional and lifestyle change. 

Mood and Cycle

Two of the main hormones that affect your feeling of mental wellbeing and clarity are oestrogen and progesterone, and these change throughout your menstrual cycle. It’s an over-simplification – but perhaps a helpful one – to think about oestrogen largely bringing positive effects to your mood and progesterone contributing more negative effects. With such a pronounced hormonal connection on mental health, it’s small wonder that women are twice as likely to suffer from depression than men.

According to the National Institute of Mental Health, 64% of women who suffer from depression say their symptoms get worse during the pre-menstrual period. Hormones are also likely to contribute to antenatal or postnatal depression, which affect around 10-15% of new mothers. And anxiety and depression are also starting to be recognised as symptoms of the perimenopause on top of hot flushes and night sweats.

How it works

At certain times in your cycle (in the run-up to ovulation), there will be lots of oestrogen in your system and women tend to feel brighter and better in their mood. You might even notice at this time you feel better at talking and articulating yourself. In the second half of your cycle, oestrogen dips, and progesterone comes into play. For some women, this can lead to lowered mood or depression.

You might already experience this as Pre-menstrual Syndrome (PMS), a very common condition linked to the changing levels of these hormones, that might include feelings of bloating, breast tenderness or headaches, or manageable emotional symptoms like irritability. For a small number of women (about 2-8%), the effect of these hormones on their mental wellbeing is pronounced. This is called Pre-menstrual Dysphoric Disorder (PMDD); an extreme form of PMS and one that, if you think might apply to you, you will want to ask your doctor about.

Why does this happen?

One of the first things to know is that the production of dopamine and serotonin (the two main brain chemicals associated with the development of depression and psychosis) is heavily linked to levels of oestrogen. 

Research seems to suggest that there isn’t a noticeable difference in levels of oestrogen between those who are affected by mental health symptoms around their period or during the menopause – it seems some women are just especially sensitive to hormonal change, or perhaps also that lifestyle problems like stress may also play a big part.

Impact of hormones on blood sugar levels

Declining oestrogen levels have a role to play in insulin sensitivity (that means how sensitive – or not – the cells in your body are to the fat storage hormone insulin). In fact, a lack of sensitivity to insulin (or even being resistant to the effects of insulin) is lurking behind many of the common menopause symptoms, like hot flushes, fatigue and weight gain as well as symptoms of low mood like brain fog, anxiety and depression.

Hormones and mental health is a complex picture in which your physiological health and mental wellbeing are inextricably intertwined. It might be best to work with a nutrition practitioner to unravel this for you. We might be able to piece together a hormone balancing food and lifestyle plan to suit your circumstances. Get in touch if you feel you'd like to discuss this further.

Are you functioning on all cylinders?

If you often feel you’re dragging yourself through the day or you've been struggling to lose weight for a long while despite eating all the right things, it might be worth considering whether your thyroid is doing the job it should. 

The thyroid – a butterfly-shaped gland located in the neck – is the body’s internal motor, effectively setting the speed at which the body works. If it’s not up to scratch, you might experience a whole host of uncomfortable or annoying symptoms (see below). 

The hormones it makes affect most cells in the body by increasing the basal metabolic rate, as well as augmenting heat production. That’s why people with an underactive thyroid often struggle to lose weight, feel the cold more easily and have low energy – imagine a record player playing a record at reduced speed.

Do any of these sound familiar?

  • I feel tired all the time
  • My hands and feet are always cold
  • I’m putting on weight for no reason
  • I can’t seem to lose weight whatever I do
  • I’m often constipated
  • My muscles ache
  • I get muscle cramps more often
  • I feel irritable
  • Generally, I’m feeling a bit low
  • I’m struggling to fall pregnant
  • My periods are heavier than usual
  • My hair and skin feel so dry
  • My sex drive is flagging or non-existent
  • I’m losing hair at the outer edge of my eyebrow.

If more than a few symptoms resonate with you, visit your GP to discuss symptoms and ask to get your thyroid tested. 

GP testing

One of three things will happen after you have a blood test at the GP. The doctor may tell you your results look normal, in which case no further action will be taken*. Or you might be sent for further testing, if the result looks a little off, either immediately or for a retest in a few months’ time. 

It’s much more common to have an underactive thyroid than an overactive one, and more common still for the underactive thyroid to be an autoimmune condition called Hashimoto’s, where the immune system destroys the thyroid gland to the extent that it can no longer function normally. 

However, even with a diagnosis, many people still experience symptoms in spite of treatment.  

What actually gets tested? 

In the UK, the first thing doctors test is Thyroid Stimulating Hormone (TSH) levels. TSH is the hormone that tells your body to produce the actual thyroid hormones. If TSH is within range, your GP is unlikely do any further tests on the assumption that the rest of the thyroid hormone-producing cascade is working correctly. 

If TSH is raised, your body is working harder than necessary to produce the right levels of thyroid hormones. At this point, your doctor may repeat the TSH test in a few months in order to compare levels. 

Alternatively, they might test your Thyroxine (T4) levels to determine whether or not you’re producing the right levels of this hormone. 

If this level is below range, you’ll likely be prescribed a synthetic form of thyroxine to supply the body with what it is not making itself. If the levels is above range, which suggests an overactive thyroid, you may be prescribed carbimazole and perhaps a beta-blocker.

*Still feeling tired and ‘rubbish’ despite treatment?

This a common problem. Initially, you may start to feel better, but many patients report sliding back into their previous pattern of symptoms.

The reasons why you’re not feeling better can be complex.

  • Supplementing with T4 might not work, as what’s going on in your body might be more complicated and involve several issues.
  • Some people produce enough TSH and T4, but T4 isn’t actually the hormone that does the work.
  • Triiodothyronine (T3) is the ‘work horse’ that needs to be converted in the liver from T4. Some people, for various reasons, simply don’t convert it very well.
  • In other cases, you might produce enough TSH, T4 and T3, but the body negates the effects of the usable T3 by making reverse T3 (rT3) –literally reversing the action of T3.
  • Everything may ‘look normal’, but if you’re still dragging yourself through the day, you could have sub-clinical thyroid problems. GP ranges are quite broad, so it’s easy to fall outside the limits. 

It’s worth knowing that regular GP testing does not cover T3 or rT3, so if you’re still feeling below par, it’s worth getting a full thyroid blood screen done privately. I work with all major private laboratories and can arrange this for you.

Do you have an autoimmune thyroid problem?

Another vital piece of information, which isn’t often covered by the standard GP test, is for the presence of autoimmune thyroid antibodies (thyroid peroxidase and thyroglobulin). This indicates your immune system is attacking your thyroid.

The autoimmune disease Hashimoto’s Disease (a form of underactive thyroid) is incredibly common but unless your GP tests for the antibodies, you won’t know that you have it.

GPs generally don’t test for this as it doesn’t affect their clinical management of you – whatever the diagnosis, you’re still going to be prescribed thyroxine.

However, this test is important to nutritional therapists, as the diagnosis requires an entirely different treatment protocol.

You may have high levels of these antibodies, but no symptoms of an underactive (or overactive) thyroid. The autoimmune element always comes first. 

Hashimoto’s (underactive) and Graves’ (overactive) Disease affect the thyroid, but they are actually immune system disorders. 

Adrenal stress - the missing link in thyroid treatment

Thyroid health is closely connected with your adrenals (two walnut-shaped stress glands located on your kidneys). If you have had any significant stress, your adrenal glands may not be performing optimally – and this is very bad news for thyroid health.

Adrenal stress disrupts the complex network of interactions needed to make the right amount of thyroid hormones, suppressing the thyroid function.

There are tests available privately for this. Unfortunately, adrenal problems are not recognized by UK GPs. 

Addressing adrenal problems is important because the effects of stress affect energy production, fat storage (storing fat around the middle) and female hormone health.  

The importance of iodine

Did you know that the mineral iodine is essential for the manufacture of thyroid hormones triiodothyronine (T3) and thyroxine (T4)? Thyroid hormones contain three or four iodine atoms respectively. If you’re serious about fixing your thyroid for once and for all, you could consider a urine test to determine whether or not you have sufficient levels of iodine. 

Ready to get that thyroid back into shape?

There are a number of different tests, which we can use to measure your thyroid levels. These include a full blood draw, finger prick blood spot test and a urine test. I take a full medical history and evaluate my clients before deciding on the best option. If you have an underactive thyroid and are feeling below par, despite medication, I can help. Medication is just a piece of the puzzle. Why not contact me here.
