Hormones and blood
There are many hormones that assist in the production of blood cells and platelets, regulating blood pressure, protection of blood cells and blood clotting. Where a patient has constant issues with blood pressure or keeping adequate levels of iron, analysis of hormones should be considered.
Erythropoietin (EPO, haematopoietin or haemopoietin)
Erythropoietin is produced mainly in the kidney, by interstitial cells. Once the hormone is made it protects red blood cells against destruction. It also stimulates stem cells of the bone marrow to increase the production of red blood cells.
Angiotensin
Angiotensin is a hormone that helps regulate your blood pressure by constricting (narrowing) blood vessels and triggering water and sodium intake. Angiotensin is part of linked hormones, enzymes, proteins and reactions called the renin-angiotensin-aldosterone system.
There are four different forms of angiotensin: Angiotensin I–IV. Angiotensin II is the main and active form of the hormone. If your body has too little or too much angiotensin, it can cause health issues.
Angiotensin II binds to several receptors and affects many different systems and functions, including:
- Stimulating the release of aldosterone from your adrenal glands, which causes your body to retain sodium and lose potassium through your urine.
- Increasing blood pressure by narrowing blood vessels.
- Triggering the sensation of thirst through your hypothalamus.
- Triggering the desire for sodium through your hypothalamus.
- Stimulating the release of antidiuretic hormone from your pituitary gland, which causes your kidneys to reabsorb water. (1)
Thrombopoietin
Thrombopoietin is the chemical mediator that regulates the number of platelets in the blood by stimulating an increase in the number and growth of megakaryocytes, thus controlling the rate of platelet production.
Vasopressin
Vasopressin is known as an antidiuretic hormone. It maintains the appropriate volume of water in the space that surrounds cells within the body. It plays a role in regulating circadian rhythm, maintains the body’s internal temperature, blood volume and the proper flow of urine from the kidneys. Nerve cells at the base of the brain (hypothalamus) make and transport vasopressin to the pituitary gland, which then releases the hormone into the bloodstream If your body produces too much vasopressin, your kidneys may retain water. If you don’t have enough vasopressin, your kidneys may excrete too much water. This causes frequent urination and can lead to dehydration, as well as low blood pressure. (2)
Aldosterone
Aldosterone is a steroid hormone produced by the adrenal glands. It supports the regulation of blood pressure mainly by acting on organs such as the kidney and the colon to increase the amount of sodium reabsorbed into the bloodstream and to increase the amount of potassium excreted in the urine. Aldosterone also causes water to be reabsorbed along with sodium; this increases blood volume and therefore blood pressure. (3)
Hepcidin
Hepcidin is a peptide hormone produced in the liver that plays a crucial role in iron production and uptake. Serum iron levels must be tightly regulated to ensure an adequate supply is available for hemoglobin synthesis, without allowing iron overload to occur in the body. Hepcidin decreases the level of iron by reducing dietary absorption and inhibiting iron release from cellular storage. Too much hepcidin can lead to problems like iron deficiency, where your body doesn’t absorb enough iron. Too little hepcidin can cause iron overload, where your body absorbs too much.
Prostaglandins
Most hormones are produced by glands and transported in the bloodstream. Prostaglandins are produced at the site where they are needed, are produced in nearly all body cells and are part of the body’s way of dealing with injury and illness, where there is inflammation, pain and fever. When a blood vessel is injured, a prostaglandin called thromboxane stimulates the formation of a blood clot; a muscle in the blood vessel wall contracts to try to prevent blood loss. Another prostaglandin called prostacyclin has the opposite effect to thromboxane, reducing blood clotting and removing any clots that are no longer needed and causing the muscle in the blood vessel wall to relax. The opposing effects that thromboxane and prostacyclin have on the blood vessels can control the amount of blood flow and regulate response to injury and inflammation. (4)

Hormones involved in Digestion
The gut is a major producer of hormones, with more than 20 known hormones being responsible for controlling food intake, digestion of food, energy expenditure and influence the pleasure of eating. Some of these digestive hormones target the brain and work in association with the enteric nervous system and is often why the gut is known as the “2nd brain”.
Some of the well known hormones are below:
Gastrin
Gastrin is a hormone that is produced in the lining of the stomach and upper small intestine and is released into the bloodstream. During a meal, gastrin stimulates the stomach to release hydrochloric acid, which then allows the stomach to break down food and absorb certain vitamins such as vitamin B12. Gastric acid also acts as a disinfectant. Gastrin can stimulate the gallbladder to empty its store of bile and the pancreas to secrete enzymes. Gastrin also stimulates growth of the stomach lining and increases the muscle contractions of the gut to aid digestion. (1)
Ghrelin
Ghrelin is a hormone that is produced and released mainly by the stomach with small amounts also released by the small intestine, pancreas and brain. It is known as the ‘hunger hormone’ because it stimulates appetite, increases food intake and promotes fat storage. Ghrelin levels are actually higher in people with lean body weight compared to those who are overweight. High levels of Ghrelin have also been found in people with certain cancers, anorexia nervosa and cachexia. (2)
Glucagon
Glucagon is made by the pancreas and helps regulate your blood glucose (sugar) levels. Glucagon increases your blood sugar level and prevents it from dropping too low, whereas insulin, another hormone, decreases blood sugar levels.
Insulin
Insulin is released from the Pancreas and is essential for helping your body use glucose for energy. If your body cannot produce enough insulin, or your body cannot use the insulin being released, it causes high blood sugar levels. In most people insulin lowers blood sugar levels, stimulates metabolism of glucose, protein, and fat. The inability to produce insulin by destruction of beta cells in the pancreas, creates an autoimmune condition which results in Type 1 Diabetes Mellitus and those diagnosed require injections of insulin for the rest of their lives. Type 2 Diabetes Mellitus is when the body cannot properly use insulin, and is often a result of poor eating and lifestyle habits which results in insulin resistance. (3) (4)
Insulin-like growth factor (IGF-1)
IGF is a hormone that your body makes naturally in the liver and acts much like insulin. It used to be known as somatomedin. IGF helps to control growth hormone secretion in the pituitary gland. IGF works with growth hormones to promote growth and development of bone and tissue. These hormones also affect how your body metabolizes sugar, or glucose. IGF and insulin can work together to rapidly reduce the level of glucose in your blood.
Leptin
Leptin is a hormone released by body fat that helps your body maintain normal weight on a long-term basis. It does this by regulating hunger by providing the sensation of satiety (feeling full). As leptin is created by stored body fat, the higher level of body fat means a higher release of leptin. This signal should mean that the person stops eating. For those on weight loss protocols, as your body fat decreases, your leptin levels decrease, which may signal your body to think that it is suddenly in starvation, which it clearly is not. This feeling of starvation can stimulate hunger and appetite and can lead to increased food consumption. (5)
Gastric Inhibitory Peptide (GIP)
GIP is a member of the secretin family of hormones. It was discovered in extracts of intestine that inhibited gastric motility and secretion of acid, and initially called enterogastrone. It is secreted from mucosal epithelial cells in the first part of the small intestine.
GIP enhances the release of insulin in response to infusions of glucose. For this action, it has also been referred to as glucose-dependent insulinotropic peptide.
Secretin
Secretin is a digestive hormone secreted by the wall of the upper part of the small intestine (the duodenum) that regulates gastric acid secretion and pH levels in the duodenum. When hydrochloric acid passes from the stomach into the duodenum, secretin is released into the bloodstream and stimulates the duct cells of the pancreas to secrete water and bicarbonate. By this mechanism, hydrochloric acid secreted by the stomach is diluted and neutralized. Secretin also inhibits the secretion of gastrin, which triggers the initial release of hydrochloric acid into the stomach, and delays gastric emptying. (6)

How to Lose Weight Safely and For Good
Despite the wide range of diets available, one in three Australians is overweight or obese. Research shows that a different, healthier approach to weight management works better in the long term than restrictive dieting. This focuses on wellness rather than weight loss.
The holistic wellness programme that I recommend to my clients includes:
· Self-compassion.
· Tools to ease yourself into habit change.
· Nourishing food.
· Jump-starting your metabolism.
Self-compassion
Many people have an unkind inner critic who drains them of motivation and stops them believing that change is possible. They berate themselves, get stressed and eat to self -soothe. However self compassion is not the same as being soft on yourself.
Kristin Neff, Associate Professor of Educational Psychology at the University of Texas at Austin and author of Self-Compassion: The Proven Power of Being Kind to Yourself, defines self-compassion as taking good care of yourself, taking the longer view about what would be nurturing for your mind, body and soul rather than looking for short term gratification.
So while one day we might feel down and remember that eating a large bar of chocolate made us feel better in the past, a more self-compassionate approach would be to do something else that also lifts the mood and is healthy.
Habit Change Tools
We often know what would be a healthier option for us but fail to follow through. Changing ingrained habits can be tough – perhaps possible with strong willpower but, in the long term, we tend to revert back to our old ways.
Dr Judson Brewer, an addiction psychiatrist in the USA (fondly known as Dr Jud), has spent much of his working life looking at how our brains work. What he has found is, when we really experience the full effects of our habits on a deep level in our body, if these habits are harmful to us, our brains will reprogramme themselves so that these habits become less attractive.
Dr Jud uses three steps to support habit change.
Habit Change Step One
He encourages his clients to map out a habit that they would like to change. This involves breaking the habit into three steps:
1. The trigger that causes us to act.
2. The behaviour.
3. The reward/result.
For example, you might come home after a hard day’s work, tired and hungry, then mindlessly over indulge in a sugary snack and afterwards feel bloated and disappointed in yourself. The trigger would be being tired and hungry. The behaviour overeating and the reward/result feeling bloated and disappointed in yourself -not such a reward really.
Habit Change Step Two
This is exploring all the results of this habit – the physical sensations in your body, emotional responses and any thoughts.. How do you feel after finishing the packet of chips?
Habit Change Step Three
Then, only when you have taken time to become fully aware of all the effects of this habit would you start changing your behaviour by replacing it with what Dr Jud called a bigger, better option. You might choose to do a short breathing exercise to get past the craving or to go for a short walk – anything that helps you feel better and healthier.
This is just a short summary of this method . For more information, please see the resources at the end of this article.
Nourishing Food
One important element to regaining your health and managing your weight is eating nourishing wholefoods, organic if possible. While everyone has different dietary needs, these are the main principles apply, whether you are vegan, vegetarian or eat meat:
· Avoid foods to which you have an intolerance or are allergy.
· Eat a varied, plant based diet to ensure you have enough fibre and phytonutrients to help your body work optimally.
· Avoid or at least minimise foods and drink rich in sugar, salt and fat such as fizzy drinks takeaway, chocolate, cakes, lollies and cookies.
· Eat protein rich food with every meal and snack to keep your blood sugar levels steady and avoid energy slumps. Think meat, fish, lentils, dried beans, nuts and seeds.
· Keep hydrated and filter your water, if possible, to avoid toxins.
Jump start your metabolism
If you have been eating junk food and living a sedentary lifestyle, it’s time to be kind to your liver and get your metabolism and digestion working well again by:
· moving more – this can be as simple as getting up every half an hour to stretch and take a short walk.
· giving your body the rest it needs both by having a good night’s sleep and taking mini breaks during the day to de-stress.
· reducing/cutting out alcohol.
· drinking plenty of water – often we think we are hungry and, in fact, we are thirsty. Drinking enough water helps our brains and bodies feel better and work optimally.
You are enough now
While we are bombarded with images of slim, athletic people on screen, if you look around you’ll notice that is not what the average Australian looks like. People come in all shapes and sizes and that makes life interesting.
Think about someone you find attractive and you might notice it’s much more than what they look like. It’s often their sense of humour and the way they make us laugh – or common interests and values that we share. So be gentle with yourself. Life is short and enjoy where you are now while you celebrate gradually easing yourself into a healthier lifestyle to feel better and more energised.

Find out what you are made of
Have you ever walked around a health food shop or browsed the isles of the supermarket looking for something to make you feel more energetic, sleep better or lose weight? If so, you are one of the many people who self-diagnose and prescribe natural remedies to feel better. Is this effective, or do you end up with a drawer full of supplements that “just don’t work”?
At Torrens University Australia, The Practice Wellbeing Centres, we believe in a two-pronged approach to wellness. The first step is to evaluate your overall wellbeing with a personalised consultation. Personalised consultation evaluates your individual health status, taking into account your health history, diet, lifestyle and other social determinants of health. Deep understanding of these factors allows your health professional to ensure any treatments are tailored to your needs.
The second step is to evaluate your body composition using a tool called a Bioelectrical Impedance Analysis (BIA). BIA assesses a wide range of body composition markers including weight, body mass index, basal metabolic rate, intra and extracellular water, muscle mass, fat mass, skeletal mass, biological age and a range of other useful markers. Not only does a BIA take measurements of the whole-body composition, it is also able to provide measurements for specific limbs, which can be very useful, particularly for people looking to optimise physical functionality.
A comprehensive personalised consultation with BIA may help with:
- improving physical health
- weight loss or weight gain
- enhanced athletic performance
- recovery from an injury
- prevention of disease
- healthy ageing
- monitoring of treatment efficacy
It’s important to note that BIA is not suitable for pregnant women and individuals with electrical implantable devices.
What is Bioelectrical Impedance Analysis (BIA)?
Health professionals around the world commonly use BIA because it is a non-invasive, low cost, fast and reliable approach that provides valuable insights into their client’s general health and wellbeing. Used in conjunction with a full consultation, BIA allows the practitioner to understand your baseline health, adjust treatments to suit health and disease risk profile and monitor treatment efficacy.
How does BIA work?
Bioelectrical impedance analysis is very similar to standing on a set of scales. In addition to measuring your weight, BIA devices can also take very precise measurements of your body tissue composition by sending a low frequency electrical current around the body. As the current travels around your body, the BIA device constantly measures the resistance of the tissue it is travelling through. For example, the current travels quicker through blood, less quickly through muscle, less quickly through fat and even less quickly again through bone. In less than one minute, the BIA device calculates the composition of your body based on the resistance of the current travelling through your tissues. Following that, it presents this information in a comprehensive, user-friendly report.
How can BIA help me?
Undertaking a BIA is useful for a number of reasons. Firstly, BIA is a great tool for establishing baseline markers. Maybe you are looking to achieve a goal weight (ie. lose weight or put on muscle)? By taking comprehensive baseline measurements, it is easier to track your progress with subsequent BIA scans and to fine-tune your dietary and exercise regimen to optimise results.
Secondly, BIA provides an insight into the composition of your body, allowing for highly individualised dietary and lifestyle recommendations. For example, the BIA can provide insight as to how much fat tissue you have, where it’s distributed throughout your body and whether or not it may be posing a risk to your health.
Thirdly, BIA can be useful in identifying a potential issue before it becomes a problem. If you were to get a BIA every 3–4 months, changes in body composition can be closely monitored. For example, your fat mass might be slowly increasing and your muscle mass might be decreasing over time (which is a risk factor for a number of chronic diseases). A BIA can identify these changes before they become a problem, allowing for fine-tuning of dietary habits and lifestyle practices.
How do I get a BIA analysis done?

4 ways in which Naturopaths can Support Patients with their Oncology Journey
Welcome to PROSPER, the forefront of natural cancer care in Australia.
I’m Carla Wrenn, a Naturopath and Nutritionist with a passion for supporting individuals through the complexities of cancer diagnosis, treatment and survivorship with evidence-based complementary medicine and integrative oncology strategies through my program PROSPER Natural Cancer Care. With over two decades of experience and accolades including the Australian Traditional Medicine Society Practitioner of the Year 2023, I’m here to support you with the knowledge and tools to navigate your cancer journey with comprehensive, personalised care, hope, and confidence.
A Holistic Approach to Cancer Support
PROSPER Natural Cancer Care embodies a multifaceted approach to oncology helping people with cancer safely blend conventional treatments with evidence-based complementary strategies. Principles of integrative oncology are laid out by the Oncology Association of Naturopathic Physicians and Society of Integrative Oncology. Let’s explore the pillars of this comprehensive approach:
- Minimising Treatment Side Effects: Cancer treatments can often bring challenging side effects, impacting quality of life. Through research evident herbal, nutritional and lifestyle medicine techniques, including turmeric, green tea (EGCG), medicinal mushrooms, vitamin D, mind-body practices, and tailored dietary interventions. I aim to mitigate these effects and promote your overall wellbeing.
- Research-backed Supplements for Chemoprevention: Complementing conventional oncology treatments – ‘chemopreventation’ refers to the administration of a medication or supplements for the purpose of preventing disease development, addressing the ‘terrain’ of cancer growth and aiming to reduce risks to progression. Evidence-based supplements play a crucial role in addressing underlying factors or ‘Hallmarks of Cancer’ contributing to cancer progression. By safely integrating these supplements into your treatment plan, I strive to optimise outcomes and support your body’s own cancer defences.
- Addressing Comorbidities: Co-existing health conditions can complicate cancer treatment, influence outcomes, and affect quality of life. By addressing these comorbidities with personalised management strategies, I aim to optimise your health and resilience, while also enhancing your ability to navigate your overall longer-term wellbeing.
- Education on Lifestyle Medicine: Considering diet and lifestyle factors including nutrition, movement, sleep, purpose, stress management – these lifestyle factors wield immense research evident benefits in cancer prevention and management. Through education and guidance, I create a personalised plan to make informed choices that support your body’s natural healing processes.
Your Path to Empowerment
Whether you or your loved one are experiencing cancer – at diagnosis, during or after treatment; PROSPER Natural Cancer Care and complementary medicine may assist you to optimise your health, minimise side effects and promote overall well-being. While helping you feel confident to safely use natural medicines.

Steps to Acne- free Skin: A Naturopathic Perspective
Understanding Different Types of Acne
To effectively address acne, it’s important to identify the specific type you’re dealing with, as acne manifests in various forms.
Identification involves examining its location, appearance, itchiness, and timing. Swabs can also be used to pinpoint certain types.
For instance, fungal acne results from an overgrowth of yeast on the skin, often seen around the hairline, forehead, temples, chest, and back.
Cystic acne presents as deep, pus-filled cysts beneath the skin, often causing pain and scarring.
Hormonal acne, triggered by hormonal imbalances like excess oestrogen or testosterone, typically appears around the jawline, chin, and mouth.
Step 1: Nurturing Liver and Gut Health
The liver and gut significantly influence acne. If the liver has sluggish detoxification, toxins will be expelled through the skin, the body’s largest organ, in the form of acne.
Supporting the gut involves maintaining adequate fibre, water, and prebiotics intake, along with regular and gentle exercise. Hydration and consumption of nettle tea can aid kidney function. Detoxification should proceed gradually under professional guidance, starting with gentle measures like dandelion tea or supplements such as glycine and taurine. This gradual process reduces the chance of a purge of acne or a sudden worsening of symptoms. Imbalances in gut bacteria, as well as parasites, may also contribute to acne, warranting assessment through comprehensive gut microbiome tests, that can be prescribed through a naturopath.
Step 2: Getting Blood Work Analysed by a Naturopath
Nutrient deficiencies often get overlooked as a cause of acne. That’s why it’s important to get a thorough blood test. Your body prioritises getting nutrients to your vital organs first, so if there’s not enough to go around, your skin loses out. A blood test can also check for thyroid issues, inflammation, or major nutrient shortages. For example, many women who menstruate have low iron levels, which are important for both thyroid health and healthy skin.
Step 3: Keeping Skincare Simple
With so many skincare products out there, it’s easy to feel overwhelmed. But when it comes to acne, less is often more.
Your skin’s pH balance is important—it likes to stay between 4.7 and 5.75. But a lot of modern skincare products can interrupt this balance. Using diluted white vinegar in water as a toner on your skin can help bring it back to a healthy pH and restore its acid mantle.
Step 4: Awareness of Endocrine Disrupting Chemicals
Endocrine-disrupting chemicals (EDCs) are always something to consider when treating acne as they can exacerbate the condition by interfering with hormonal balance. EDC’s are natural or human made chemicals that may mimic, block or interfere with the body’s hormones, which are part of the endocrine system.
Minimising exposure to EDCs involves avoiding plastic containers, reducing the use of perfumes and harsh cleaners, and opting for gentler cleaning alternatives like vinegar and baking soda.
