Your liver is a vital but often unappreciated organ.
You are probably aware of your heart when it starts pounding as you run up a hill or run for the train. Or you might pay attention to your lungs when you observe your breath, practice relaxation or if you suffer from asthma. But I’m guessing you spend most of your days completely oblivious to the critical role your liver plays in your health. And the thing is, we often put our livers under enormous pressure (without realising it) when they already have such an important role in our ongoing health and vitality.
Among its functions, your liver plays a vital role in the safe digestion of everything you consume.
Your digestion is responsible for breaking your foods down into glucose, amino acids, essential fats, vitamins and minerals. The by-products of all the complex chemical processes that need to happen to digest your food then need to be made safe for excretion (largely via the bowel and kidneys). This detoxifying activity is one of the main jobs of the liver.
The liver is also responsible for protecting you from any external “toxins” you may take in. These could include chemicals, food additives, pollution, pharmaceutical drugs, alcohol and a diet of highly processed foods. (See Is your environment the cause of your illness for more detail on some of these external toxins).
Furthermore, the liver is involved in the processing and regulation of your hormones, filtering the blood, production of bile to assist in fat digestion and also the storage of certain vitamins, minerals and nutrients.
The liver is a very busy organ so as you can imagine a healthy working liver is extremely important to maintenance of your good health. It’s also a very forgiving organ but that’s no excuse for not showing it some love from time to time.
Signs and symptoms of a liver struggling to cope
The clues to recognising a liver under pressure are numerous and it can often be difficult to distinguish them as problems of liver function as opposed to some other health condition.
A liver struggling to cope with the demands of your lifestyle and diet may produce signs and symptoms such as:
- constipation, flatulence, bloating or nausea
- bad breath
- migraines or headaches
- dark circles under the eyes or a yellow coating on the tongue
- loss of appetite
- skin problems
- immunity issues (including auto-immune conditions)
- arthritis or general aches and pains
- difficulty digesting fatty or rich foods
- food intolerances or sensitivities
- sleep issues (especially waking at around 3am)
A liver under excess pressure may also result in hormone imbalances which can then lead to further symptoms such as poor libido, PMS, menstrual irregularities and problems with thyroid function for example.
Even anger can be a sign of an unhappy liver (ever heard the expression…”he is a bit liverish”?).
A liver that is struggling to perform its duties because of inadequate nutrients in the diet or simply because it can’t cope with the amount of work required of it, may resort to prioritising its duties. In this case, removal of some toxins from the body gets pushed down the list and those toxins will circulate in the blood stream or be stored in the body, until such time as the liver has the capacity to deal with them. (Often these toxins are stored in fat cells and consequently sometimes difficulty losing weight can be exacerbated by poor liver function because the body needs that fat to safeguard you from toxins).
So, when was the last time you gave your liver a second thought and showed it a bit of love? If you suffer from any of the above signs and symptoms, perhaps it’s time you did.
A healthy and optimally functioning liver is crucial for your health and vitality so it makes sense to ensure your liver is working efficiently to cope with the daily demands placed on it.
How do I assess the health of your liver?
The first step is to take a thorough history of your health, symptoms, diet and lifestyle.
Your doctor may have requested that you have liver function tests (LFTs) in the past. This is a blood test which looks at levels of liver enzymes, bilirubin and albumin. The results of this test can be an indicator of liver damage and are therefore useful in determining or ruling out liver disease. It’s a useful test but it doesn’t tell us a great deal about how well the liver is actually working in its role of detoxification. (i.e. the liver is not diseased as such, but it’s just not working all that well).
A test I sometimes make use of is the Functional Liver Detoxification Profile (“FLDP”). This simple urine test assesses the effective operation of five of the key detoxification pathways in the liver.
It can tell us how well these pathways are working. When used in conjunction with a naturopathic assessment of your health, we can provide very targeted treatment to more quickly improve liver function.
Another test which can be useful if heavy metal toxicity is suspected is a hair mineral analysis. This test takes a sample of (uncoloured) hair to test for the presence of heavy minerals such as mercury, lead, arsenic and cadmium.
These tests are not essential (and I don’t always request them) but they can be helpful in providing more information about what might be causing your symptoms if it is difficult to pinpoint possible causes in your history.
What can you do to take care of your liver?
Firstly, stop overloading it with work by reducing the amount of processed foods, alcohol, caffeine and chemicals it is exposed to.
Secondly, in order to perform its functions efficiently, the liver requires good levels of protein. Protein provides the essential amino acids required for the numerous detoxification actions that the liver undertakes.
Thirdly consume lots of fruit and vegetables which are valuable sources of the antioxidants, vitamins and minerals required for effective liver function. A diet rich in vegetables from the brassica family (e.g. Brussels sprouts, broccoli, cabbage, cauliflower) is supportive of liver function and adequate fibre and water will help with elimination. Many nutrients are required for good liver function. These include vitamins such as B2, B3, B6, B12 and vitamin C. You also need adequate intake of folate, selenium, molybdenum, manganese, zinc and copper. So basically you want to aim for a diet that is rich in plant food with lots of colour and variation.
Brussels sprouts are great for the liver
Are you a boozy boomer?…a word on alcohol
An article in the Medical Journal of Australia (online, Jan 2019) highlighted some interesting facts about alcohol consumption.
Whilst alcohol consumption in younger people is on the decline, the proportion of those over 55 years of age whose consumption falls into the risky or high risk categories is on the increase. What is risky? Five or more standard drinks on a single occasion at least once a month is considered risky. And remember, most bottles of wine contain approximately 8 standard drinks.
It’s interesting to contemplate why (as reported in the article) alcohol consumption doesn’t seem to be declining as we get older (unlike in earlier generations). Is it because, as a society, we are working harder for longer and have more stress in our lives? Is it because we eat out of the home more often than our ancestors?
If you haven’t done so before, ask yourself why you are having that drink. And do this for every drink you have! Is it peer group pressure? Is it habit? Do you actually enjoy that second or subsequent drink as much as the first? If it is to help you unwind or switch off, do you need more than one? Is there something else you could do that would achieve the same effect? What is causing you to need to unwind in the first place?
I see many clients who find it necessary to start their day with caffeine and end it with alcohol. This is not an ideal way to live if you want to have a long and healthy life and it suggests there is something else going on which needs to be addressed. An occasional drink is one thing but regular consumption is not healthy.
Not only does alcohol contribute calories without nutrients but it also increases your risk of weight gain, high blood pressure, liver disease, some cancers, dementia and more. So make a considered decision before you have each and every drink as to whether the “benefits” outweigh the risks. And if you do enjoy a drink occasionally, make even more of a concerted effort to look after yourself in other aspects of your diet and lifestyle.
What else can you do to improve your health?
If you are concerned about the health of your liver, it is well worth investing in a thorough naturopathic assessment to ensure you are on the right track. If you are interested in herbal support, herbs which can help include Curcuma longa, Silybum marianum (St Marys Thistle), Cynara scolymus, Bupleurum falcatum and Schizandra chinensis to name a few. (Please note: herbs should not be self-prescribed. They can interfere with your medications and may be contraindicated in some circumstances).
Typically, I will develop a tonic for you using these or other herbs depending on your unique symptoms, pathology results, diet and lifestyle. I will also provide you with dietary guidance to make sure you are getting sufficient nutrients or provide additional nutrients to supplement your diet if necessary. Alternatively, our 21 day detox program may be perfect for you.
