Nutrition, gut and stress: the interaction
Your gut is your second brain. Many factors can cause persistent illness or symptoms (stress). Abdominal pain is often a signal! Read more about the interaction between stress and your gut here.
My name is Frank Jonkers, Integral practitioner and specialist with a focus on chronic syndromes and autoimmune diseases. From my BodySwitch practice in Heemskerk, I help both children and adults to improve and maintain their health. I am also author of “Kerngezond – Leefstijl als medicijn” (Core Healthy – Lifestyle as Medicine), I am founder of the BodySwitch concept, write various columns and give lectures. Since 2002, I have been studying the role that exercise, nutrition, environmental and lifestyle factors play in relation to our health. My fascination for this was triggered by my own experiences with severe obesity and health problems.
Since then, I have helped well over a thousand people regain and maintain their health.
The unique central treatment method I use is based on many trainings, scientific research and practical experience. In my practice, I help people based on a targeted approach in which I do not fight symptoms but look for the underlying causes of the complaints. To tackle these causes structurally, I take my time for the client and conduct the necessary examinations, including specialised laboratory research. Treatment is based on the cause of the complaints and restoring the balance. Based on the facts found, we draw up a tailor-made treatment plan.
I specialise in reducing persistent (chronic) complaints in a natural and healthy way.
My specific areas of interest are:
On the basis of complete diagnostics, I identify the causes of the syndrome and then treat it in a targeted manner. We do this in a healthy and natural way, focusing on the recovery of your body. This will reduce or completely eliminate (chronic) complaints. Would you like to know more? Then feel free to call Frank Jonkers on 0251 – 234 000 or get in touch. And let’s discuss what I can do for you. Often this is more than you may think right now.
See you in my practice?
Frank Jonkers
My view: Looking for the causes is the start of healing! Because if you know what is going on and what the causes are, you can provide targeted and effective treatment.
Are you ready to take action and start working on your health? I am happy to work with you to address the cause of your complaints and create more quality of life! To achieve this, I make a personal plan of action and give you personal guidance.
Are you interested? Then contact me to get acquainted or to schedule an intake interview.

Since childhood, I have been struggling with eczema and abdominal discomfort. In all those years, I have used almost all the well-known hormonal ointments, medication, antibiotics, injections, etc. Knowing that everything is temporary, and aware that the symptoms eventually came back to play. That’s how it went for years. I regained energy when there were ‘ temporary’ no symptoms. My body was tired and I also had many other complaints. For instance, I had a lot of headaches, my bowel movements were not good, and I felt kind of ‘ sick’. Another person could not feel how I felt. I couldn’t share that experience. I also started looking for solutions myself. I left dairy for a longer period, for example. And so there were more examples. During my first pregnancy and after the pregnancy, all my symptoms became many times worse. So I decided to do some research. To get an idea of how bad it was; I could not perform my duties as a nurse properly. My hands were so broken and infected from the eczema. In addition, I had intestinal problems and extreme fatigue. So I came across BodySwitch Heemskerk, Frank Jonkers, on the internet. When I looked at this website, it was actually too good to be true. Nevertheless, I made an appointment. Based on my complaints, Frank Jonkers set up a treatment plan after I submitted blood and faeces. It turned out I was sensitive to gluten, dairy and egg, and intestinal problems were the basis for the complaints I had always had. Dieting, or making a switch in your diet is really hard. I did this in combination with nutritional supplements, which were essential to solve the problems. During this switch, I had a lot of obstacles, from where to buy what, to reading labels. Every time I took food I could not tolerate I had to sit on the blisters. In time, I abandoned all the foods I reacted violently to. After about 2 months, I could let go of all my creams and the stomach pain was almost gone. I feel better than ever! The energy came back! Meanwhile, my girls also had research and treatment. They had somewhat similar symptoms to me. It is a world of difference how they feel! They no longer have stomach aches or eczema and are full of energy. Our whole family now eats what our bodies can tolerate and what we feel good about! It has cost quite a bit by now, but it is well worth it!!!
I came to BodySwitch Heemskerk because I had been suffering from diarrhoea, intestinal and fatigue complaints for years. Blood and stool testing gave me a very quick insight into what was causing my symptoms. My therapist, Frank Jonkers drew up a treatment plan with me based on the results of the tests and after a week I started feeling better. I was taking diarrhoea inhibitors and lactase pills but I was able to stop that quickly. I now follow a diet with lactose and gluten-free products, supplemented by dietary supplements. After 14 years (!), I no longer suffer from diarrhoea! Thanks to Frank Jonkers’ treatment approach at BodySwitch Heemskerk, I have my life back.
BodySwitch’s approach was very different from what I was used to. They take a very personal approach to the patient. They ask many questions and research the cause of the disease. The result is great: I am off my medication and no longer suffer from anything.”
“After years of always having vague symptoms, which started in early adolescence, always pains everywhere that later turned into really serious pains, I was finally diagnosed with Fibromyalgia in 2016/2017. I was given this diagnosis because mainstream medicine could not find anything else and had ruled out various other diseases, such as rheumatoid arthritis and ms. Conclusion: learn to live with it. I struggled on for a few more years, during which the pain and fatigue got worse and worse, and I couldn’t get off the sofa at night because I couldn’t move because of the pain. This way, I couldn’t be the mother to my daughter that I wanted to be, not the partner, friend and colleague of, but more importantly, I couldn’t be myself. I was fed up. I was 31, far too young to accept this and do nothing about it. I looked for help and found Frank Jonkers’ practice: BodySwitch Heemskerk. Frank is an Orthomolecular therapist but works more broadly (integrally, all-encompassing) with a focus on food as medicine, environmental factors and lifestyle. Frank uses very extensive blood and stool testing which goes much further than at the GP or hospital. It focuses on identifying the causes of symptoms. A very different approach. Extensive research was done and based on this, a comprehensive treatment plan was drawn up with Frank. By, among other things, banning gluten and dairy (anything to do with milk) from my diet and taking various supplements to, among other things, make up for deficiencies and solve underlying problems, I initially lost 15 kg (not the main goal, but a nice bonus) after a month I noticed a difference: my belly was calmer and more regular, my skin was calm, hair and nails grew quickly but above all: I had no more pain and lots of energy! Frank is obviously no miracle doctor but he does look for the underlying causes through specialised research. He draws up a good plan but then you really have to do and implement it yourself and go for it, but without Frank I would probably still be on the couch crying in pain. I’m still glad every day that I took this step!”

“Today I was visiting Frank Jonkers from Bodyswitch. SO interesting!!! This man has already gotten an incredible number of people off medication by using a (tailor-made) diet. For me another great challenge to do even more with nutrition!”
