My Background

This website is an avenue for communicating with my patients. I keep very up to date with health issues, especially to do with aging and hormonal problems. I will share the interesting bits with you. I have a daily blog dealing with health issues. You can subscribe to this free service by entering your email address in the space provided.

I am a GP working in Caboolture, Queensland. I have a special interest in natural hormone treatments, also known as body identical, and sometimes as Bio-identical hormones. The name derives from the fact these  hormones are identical to the hormones we produce naturally. I am not an endocrinologist, or a Gynecologist, and have never claimed to be one.

I have been using these hormones for the last 25 years, and have treated nearly 5000 people with them.

Qualifications

I have a MB Bch,(Bachelor of Surgery and Medicine).  I also have a Diploma in Obstetrics, obtained from the Royal College of Obstetricians and Gynecologists. As well I have a Diploma in Tropical Medicine and Hygiene, obtained at the Witwatersrand University, South Africa. I am a Fellow of the Royal Australian College of GP’s.  Over my lifetime I have delivered over 1500 babies, an achievement I value highly. Some of those I delivered are now my patients.

Books written:

Having studied diet, lifestyle, health and positive attitudes, I was frequently asked as to why I did not share this knowledge with others more widely. So with the encouragement of my wife, I would get up at 4 am to research and write “Live Well Over 100.”  The first edition of 5000 sold out very quickly, so more study and earlier am starts led to the second edition, which was a lot bigger and more in-depth. The print run of 20,000 sold out fairly quickly as well. I was invited to speak at various health related conferences, something I really enjoyed, as I got to meet people from various parts of the world. I spoke in conferences in New Zealand,  Singapore, Philippines, South Africa and Australia of course. Unfortunately, the book is now out of print, and is no longer current as it was written over 15 years ago.

Live Well Over 100

While touring New Zealand and giving talks at various venues, I met Michail Borrisenko, who had a great interest in Colostrum, and the many health benefits thereof.  Michail and I coauthored  “Microbe Apocalypse- Man Vs Microbe'”.  Michail Borrisenko, is chief scientist, Institute of Colostrum Research,  New Zealand.

Microbe Apocalypse

I wrote “The Medical Vitadiet”, which has sold over 25,000 copies to date. This deals with the benefits of the low-calorie diet to produce weight loss. At one stage I had 5 weight loss clinics in Queensland, with very successful results. Having decided to move on to other aspects of health, I sold the business, but allowed the new owners to continue to use the book I wrote as part of the program.

Women’s Hormones.

Some of the motivation for this web site is to present the medical evidence and research to reassure men and women about the science behind what I do and to refute some of the misleading information   about Natural (Body identical,Bio-identical) HRT.

  1. Thank you for being a doctor and advocating for hormone therapy! It is so difficult to explain how life limiting menopause is. And the fact that you understand the benefits of troches is huge. Yes some women have it easy, I am not one of them. I can’t get out of bed, I have disassociation disorder, I cry, and I’m suicidal when not on my hormones. I would not be here or possibly even alive now if I hadn’t lucked into finding a similar doctor like you. (Very VERY hard to find) I’m not being dramatic I just am sharing my reality so others can understand and not dismiss the women around them going through this as this being “normal”, Or worse by offering therapy or vitamins or soy something or other or whatever other garbage folks want to hawk. I have ZERO hormones unless I’m on my meds. Not a little, not some, I have unregistered levels. There are other women like me in the world, there is medicine that can really truly help them. So… Thank you for saving lives…

  2. Hi, Dr Colin Holloway,
    Would you be so kind as to direct me to your Blog on Rabeprazole. After our phone consultation, 30/5/22, it was mentioned and warned re long term use. I am researching of course, but would like to read your blog on the matter, and don’t seem to be able to search on this area.
    Thanking you in advance
    Traute Meyer

    Good afternoon Colin, I was recommended by a friend in Coffs Harbour to see you. As your appointment books are closed, could you recommend somebody who can me utilising your approach to help menopausal symptoms. I had minimal menopausal symptoms when I was going through changes which had ceased…but then after vaccines the side affects are now what most women I’ve heard talk about. I’ve had constant headaches for about 5 months, can’t sleep ( awake most nights from midnight) moods swings are crazy and the hot flushes are insane( they include a rush of agitation) AND not to mention the body fat around my mid section which I’ve never had before. Yep I’m a perfect candidate…. Please help:) thank you for your time . Warmest regards Di

    Goooood morning Colin!

    HELP I am hoping I could please come in and see you TODAY if possible. I am taking my 3rd lot of troches and I feel sick, my glands are up and I have sore ears, feel emotional and nervous (this started on the 3rd day) The first lot I was tired with very tender breasts 1.5m testosterone. My 2nd lot where I felt the best 2.5mg testosterone, I was angrier than normal, My 3rd lot – I believe if I continue to take the 2nd script and reduce the testosterone to 2mg would work? Can you please call me 0452 076 885. Very grateful Sharon Douglas
