Merridy Casson

Experienced Naturopath Adelaide

Weight Loss Specialist

Achieving your desired weight involves much more than just burning more calories than you are eating. Make no mistake, calorie counting does not work. Better health and wellbeing, including an ideal body weight comes from eating good quality food.

Skin Expert

Skin conditions require much more than creams and lotions to resolve.  They often reflect a number of other issues such as food intolerances, inflamed and dysfunctional gut, histamine sensitivity and mood disturbances.

You can heal your skin!

Sleep Program

After over 20 years of clinical practice, Merridy devised a 10-Day Sleep Reset Program. Most of us are impacted at some point in our lives by sleep deprivation. For example, new parents, stressed workers, students, athletes and busy people feel the effects of poor sleep.

You can reset your circadian rhythym and feel much better in days!

Allergy Specialist

Do you suffer food intolerances, mould toxins or pollen and grass allergies?

Taking antihistamines can offer short-term relief, but recognising what is triggering the reactions and improving both gut and immune function, dietary intake and detoxification if needed, will enable resolution of allergic reactions.

Find out how!

Weight Loss Specialist

With 63% of Australians now overweight or obese, we need to acknowledge that support is needed. Many people are overwhelmed by overweight issues and find it difficult to get started on a path to recovery. The notion of weight loss being about burning more calories than we eat is a fallacy. Make no mistake, losing body fat comes from eating better quality food.

This is where Merridy can step in. Her experience shows that our biology is actually changed when we become overweight. Hormonal balance is upset, our gut chemistry can alter, brain function and mood can be impacted, chronic fatigue can result, and many other functions of the body can be affected. These functional imbalances can deteriorate into chronic disease states, which are the result of long-term inflammation and pain.

Merridy offers 3 Weight Loss Programs, so you can find one that suits your needs!

Skin Expert

Merridy’s approach to managing skin conditions, from chronic acne, eczema and psoriasis to hives and Roseacea, will always include consideration of the state of the gastrointestinal tract or gut. This is because a poorly functioning gut can be a trigger for many other health issues, such as food intolerances, histamine sensitivity and poor mood. To ignore these related conditions, is to ignore the real causes of the skin problem.

Many people with these symptoms may suffer MCAS (Mast Cell Activation Syndrome). This can be treated and resolved when all areas are addressed.

Just applying a cream topically is rarely going to resolve a skin condition. There needs to be a coordinated dietary plan, along with recognising the impact of chemicals or toxins on our hormones, treatment of stress, food allergies, mood disorders and poor sleep.

Improve your skin at last with a comprehensive plan!

Allergy Specialist

Many people nowadays are reactive to certain foods and also have allergies to pollens, grasses and moulds. This reactivity is a real problem and much of it comes down to the over-processing of our food and/or the fact that our immune systems are not what they once were. For example, the flour that is made into bread today is a far cry from what it was like 20 years ago.

Our immune systems suffer an overload of toxins from the environment and what we eat, and from the promotion of sanitising our homes and environments constantly. Merridy’s approach, as a natural health allergist in Adelaide, is to find the cause of the imbalances or allergic reactions and treat them appropriately.

What does a naturopathic doctor do?
A naturopathic doctor takes the time to listen to the client, assess strategic treatments and to prioritise a path back to better health. A qualified naturopath holds a Degree in Health Sciences or the equivalent thereof. They are trained in the use of nutritional treatments, herbal medicine, vitamin and mineral therapeutics, stress management, massage, reflexology, clinical testing and so much more.
Finding a good naturopath in Adelaide
Merridy Casson is one of the best naturopaths in Adelaide as she offers practical, sustainable solutions for the long-term, while providing immediate support for acute conditions. She believes strongly that given the right nutrients, the body will heal itself and it is with this in mind that she seeks to help her clients restore their health. Her treatments include the use of nutritional and herbal medicine and lifestyle recommendations, which help make her solutions achievable and effective.
Why food is medicine?
We often overlook the simplest of solutions when it comes to our health. Optimal health and happiness can be achieved with a clean, wholefood diet which largely avoids processed food. It starts with creating our meals from scratch using healthy fruits and vegetables, clean protein, good omega-3 fats, fibre, beans and legumes, nuts and seeds.

The reasons many people find it difficult to improve their health is that they are derailed by poor food choices and are overwhelmed by media hype. Often better health and more energy are only days away. We don’t need to work hard for 6 months to see and feel improvement. Merridy believes we can attain great health using the power of real food and this is constantly confirmed with her clinical outcomes.

Is naturopathy regulated in Australia?
The simple answer is no, but finding a qualified naturopath who has a strong reputation is highly advised. Checking reviews and feedback from clients regarding health outcomes, will ensure that you select an experienced and reputable naturopath.
How much does it cost to see a naturopath?

Fees and costs involved vary a little from one practitioner to another, but will usually fall in the range of $150 – $400 for a 60-90 minute initial appointment, while follow-up appointments are somewhere between $95 – $200 for 30 minutes.

At 15, I had been dealing with bloating, skin irritation and digestion issues for years. I saw Merridy who helped me understand the real issue with my gut, and what effect different types of foods had on me. After changes to my diet and taking her advice, The constant stomach pains and bad skin are gone. Without much effort and following Merridy’s eating plan I have become my healthiest self. I even lost excess weight which wasn't the plan. I would absolutely recommend Merridy's practice to anyone.

Decided to visit an naturopath after having a Gall bladder attack that resulted in Gall bladder removal surgery. Merridy was very welcoming, listened to my concerns and advised of dietary changes and supplements to help the gut. After several weeks of actioning this plan my gut issues have eased considerably.I would certainly recommend Merridy Casson if anybody was looking for a naturopath for their health concerns.

I discovered Merridy online, as I had relocated back to Adelaide. I was having an allergic reaction,had given up on general medicine and in great discomfort.Merridy took the time to understand and listen, started me on a low histamine diet. Within 2 weeks I felt much relief and then concentrated on energy levels.2-3 months later, I’m very happy with how I feel, more like the “old” me.I cannot recommend Merridy enough!

Before seeing Merridy I had been suffering with food intolerances, poor gut heath, eczema and excessive weight gain for over 2 years. After seeing several doctors and naturopaths with no success, I was starting to think that no one would be able to help me. I could tell from the moment I met Merridy that she was genuine about wanting to help. After my first consultation she had quickly identified the cause of my problems and gave me a practical step by step plan on how adjust my lifestyle to improve my health moving forward. Within 6 weeks I felt like a new person; my skin had cleared up, I was able to eat without stomach irritation and I lost 13kg. I can’t thank Merridy enough for all her help, she has honestly changed my life.

Started my journey with Merridy in June to recover extreme bloat I’ve been struggling with for 4+ years. She has been so understanding and is willing to try everything she can to help my gut. She has suggested the most easy (yet most effective) diets/plan to help me recover. I am 2 months into the process and am already feeling so much better. Would highly recommend her 😊

Merridy was recommended to me regarding my joint pain and general wellbeing. Merridy initially suggested a strict autoimmune diet as well as natural supplements to improve my gut health, and then slowly reintroduce food groups, depending on my reactions. Within 2 days my hands were pain free (after 10 years of suffering). By the end of 2 months I was totally pain free and I generally felt so much better and had more energy. I am so grateful to Merridy for showing me how to change my diet and cooking. I am very happy about the changes and would gladly recommend Merridy.

I highly recommend Merridy Casson. I went to her with inflammation around my body, feeling lethargic, bloated and insomnia. Merridy started me on an anti inflammatory diet and some gut health supporting vitamins. Within the first week I felt the changes. As the weeks and months progressed, with Merridy's support, I feel fantstic, fitter and healthier.

I saw Merridy for ongoing sinus problems, throat irritation and incessant coughing. These issues had worsened over a 3 year period. My GP's solution was a nasal spray and a puffer. Neither resolved the issue and I was at my wits end. I needed to make the decision of either seeing a specialist or go down the nutritional/naturopath path. I am very grateful I chose the latter. After doing my research I decided to make an appointment with Merridy. At my first appointment Merridy asked a number of questions to gain a full understanding of my medical history, diet, exercise regime and general wellbeing. After discussing her thoughts around the possible causes of my health issues, potential solutions, and the reasoning behind these thought processes, a strategy was devised that included tweaking my current diet and the inclusion of 3 natural products that would potentially address the areas of concern. We also discussed the importance of gut health and its relationship with day to day health. Within 24-48 hours of commencing the supplements and tweaking my diet the sinus issues improved, the throat irritation and incessant coughing stopped. I was astounded at how quickly my body responded to the products and change to my diet. I would highly recommend Merridy to anyone looking for a naturopath and nutritionist.

I completed a 4-week detox and a weight loss program with Merridy as I trusted her to help, educate and guide me with what foods to eat and illuminate from my diet that played a vital role in improving my sense of wellbeing and mood.Happy with my results from completing a detox program, I return to Merridy to help me loose weight that I had gained from not being mobile for several months due to a back injury.Not only had I lost weight but I felt more focused, motivated, energised and happy.

I started seeing Merridy when I was feeling lower abdominal pains, bloating and getting regular migraines. Visits to the GP and Gynae weren't giving me the answers I was looking for. Merridy had made me feel very comfortable with her kindness, professionalism and knowledge. I am happy to say that I no longer get migraines and have improved on my eating habits. I highly recommend Merridy.

Also had stomach problems which have also improved . I highly recommend Merridy

When my son's skin starting flaring up I knew we needed to get to the cause of the problem rather than just treating it topically. I am so grateful that we found Merridy. She is extremely thorough and is very caring and supportive. She explained things in a very understandable way and continued to answer my many questions during the first few weeks of a new nutritional plan combined with supplements. We are so happy with the results in a relatively short amount of time. I've learned so much about healthier yet still delicious ways for the whole family to eat. I cannot recommend Merridy enough, she is a fantastic practitioner who really does care.

Merridy has changed my life!Unlike other practitioners Merridy really listens and explains things in a way that is easy to understand, she has been able to help me with an array of issues such as gut health, skin, sleep and hormonal imbalances. After the first appointment I walked away with a new treatment plan that really worked.Before meeting Merridy I was constantly fatigued, unbalanced and foggy. Now, thanks to Merridy’s help, I wake up feeling energised and motivated, I never knew I could feel this good. My only regret is not meeting her sooner!Merridy makes you feel extremely comfortable and welcome in her clinic, she is always going above and beyond. I can’t recommend her enough.
01:13 16 Jan 21
Merridy was so helpful in helping me control my urticaria without medication. I can not thank her enough. Every doctor and specialist I went to kept giving me medication to treat the symptoms not the underlying cause. She is very knowledgeable about gut health and women's health which is hard to find. I highly recommend Merridy

When I first went to see Merridy I wanted an overall check of my health as I experience anxiety, brain fog, bloat, weight gain and acne. During her consultations she really listened to what I was experiencing and explained medically why I have these symptoms. After 6 weeks of seeing her, taking herbal supplements and following my new diet I lost 5kgs I'm less anxious and my gut health is resolved. I have been so happy with the results so far that I keep seeing Merridy to further better my health.

I cannot begin to thank Merridy enough. My first consultation with Merridy was on 30th July. Nausea, bloating, cramps, indigestion, GORD, frequent bowel movements were a few of the ailments that plagued me; some for years. GPs had referred me to specialists and I had endured ultrasounds and a CAT scan in attempts to diagnose the causes, without success.Within a fortnight of the introduction of the Allergy and Reactivity Reduction Program, my nausea was diminishing, and completely disappeared after three weeks. There is a new and exciting motivation to my life now; a discipline that had evaded me for years. The sleep program is simple and so effective. I am finding myself yearning for bedtime at 9:00pm, whereas my "normal" bedtime was always after midnight.I appreciate how Merridy is celebrating the positive changes to my health as much as I am!

I started to visit Merridy since May this year. I've been suffering from anxiety and sleeping disorder since last July when something traumatic happened to me. After I started the 10 days sleep program and other treatments with Merridy, I could feel the changes. I can fall asleep in a short period of time at nights and wake up less often than I have been. I also become less anxious, less lethargic and brain fog has getting better. I will continue to visit Merridy and I would recommend Merridy if someone is experiencing the same problems.

I have been seeing Merridy for the past 3 months. After a number of years of weight gain, lack of sleep and gut health, Merridy is truly amazing and has the ability to create such a change in your life and promote confidence within you. She is passionate, caring, dedicated and has the knowledge to help people achieve their health goals and her process of bringing out the best in you with such a gentle, nurturing approach. The 10 day sleep reset plan put me on track with my sleep. If you want to move forward with your health Merridy is highly recommended. Thank you for all you’ve done.

Considering I wasn’t that much overweight when I started my detox (start 59.6kg) I’m thrilled with the amount of fat loss. I did this as my clothes were giving me muffin top & I was undoing top buttons of pants when sitting. Clothes had become very snug. They are now loose. Yipee…!!Along the way though I have enjoyed many other benefits that I didn’t think about at the start.My sleep is great every night.My skin is clear, doesn’t get dry & generally looks brighter.My hair is shinny.My nails are super strong.No more bloating & fluid retention.Energy to burn.Thanks for your support & knowledge Merridy.

Best decision I ever made.It took me lots of courage to contact Merridy and I got response from her within 24 hrs. I have been trying to lose weights for a while now but I always put on extra after few months instead. I was quite stressed, depressed, worried and bad mental stage at my 1st consultation with Merridy.After our 1st session, I felt Merridy really listens to me, no judgemental and always gives me the advice to look the problem different angles and guides me through the reasons why my body + mind + guts are all in very bad stage. Then she guided me through step by step. Honestly, after our package, I changed a lot of the way how I look at my life, better understanding of my body, eat much better and be happier, more confident in life. I didn't drop much of weight but I lost quite a bit of cm around my abdominal, gain a bit of muscle.

I went to see Merridy last year with a huge range of symptoms including constipation, reflux, food intolerances and Pain. Merridy ordered some tests and I was diagnosed with SIBO. After a comprehensive program of supplements and diet all of my symptoms have gone. Merridy was available for my many questions by phone and email and I felt finally like someone understood. Merridy clearly knows her stuff and I would not hesitate to recommend her to others.

I never knew I could feel so good, and within just 3 sessions, she has solved all my problems and concerns relating to my body. Merridy should so be proud of her work and I highly recommend her to anyone seeking naturopathic assistance.
