Health information is only worth something if you know who wrote it, what it is based on, and when it was last checked. This page sets out how we work, so you can judge our articles instead of having to trust them.
K.Y.J.A.M. Ho, MD PhD — physician and researcher (PhD cum laude, Maastricht University), former interventional and cardiovascular radiologist, with around 25 peer-reviewed publications (including in Radiology, Circulation and European Radiology) and two US patents. Internationally registered medical specialist in the Netherlands (BIG 59043538701), the United Kingdom (GMC 4141501) and Dubai (DHA 79157006). He writes the content and is responsible for its medical accuracy.
C. Pleiter — neuroradiologist and medical reviewer. He checks every health article for medical accuracy, for how faithfully the research is translated into plain language, and for whether the evidence grading matches what the sources actually show.
More background on the team is on the about us page.
1. Question first, topic second. We do not write about a subject because it attracts search traffic, but because the question is genuinely asked in practice. The basis is a collection of 935 questions that patients and clients asked us in the consulting room.
2. Finding and weighing sources. We start from systematic reviews, meta-analyses and randomised trials, supplemented by Dutch and international guidelines. Where only animal research, small studies or observational data exist, we say so.
3. Writing with the range attached. Where an effect can be expressed in numbers, we give the number and its spread — not the most flattering figure from the most flattering study. Where the honest conclusion is "we do not know yet", that is what it says.
4. Medical review. An article only goes live after the medical reviewer has checked it. The date of that review is shown at the top of the article.
Strong — direct, consistent results from randomised trials or meta-analyses, in a population and an intervention comparable to what we are writing about.
Moderate — the evidence points the same way but is less direct: smaller studies, shorter duration, surrogate outcomes, or a different population than the reader.
Emerging — interesting and possibly important, but not established: animal research, laboratory work, small studies, or results not yet replicated. What is written here may look different next year.
We apply these labels even when they work against us. If something is popular but weakly supported, it does not get a stronger label because the conclusion would be more convenient.
Every health article is reviewed at least once a year, and sooner when relevant new research appears or a guideline changes. Each article shows when it was published and when it was last medically reviewed. Those two dates are deliberately separate: a textual correction is not the same as a substantive reassessment.
We make mistakes. If you spot one, email info@drhealthy.nl with the page and what you believe is wrong. If the correction is justified we amend the article, update the review date, and note what changed when the change is substantive. We do not delete criticism and we do not let an error disappear quietly.
DrHealthy sells no supplements, no medicines and no devices, and is not paid by their manufacturers. There are no advertisements on this site and we use no affiliate links. Our income comes from our own guidance programme. That is itself an interest, which is why we keep the knowledge articles and the offering separate: an article never proposes the programme as the answer to a medical question.
This site gives general, evidence-based information. It is not a diagnosis, not a treatment and not a replacement for your own doctor. What is sensible for you, and whether you can adjust your medication, is always a conversation with your own doctor. Never change your medication on your own.
