Care Philosophy

I am a doctor who takes time to listen to your concerns, and includes you in making decisions abut your care. When possible I prefer to avoid antibiotics and other prescription medications as they the often have unwanted side effects. I also prefer to treat the root cause of a problem rather than bandage over the symptoms.

I am so impressed with Dr. D.Years of being dismissed by my sons pediatrician and telling me his symptoms were normal and no big deal left me frustrated; I knew something was not right so I went for another opinion w Dr.D. At the 1st visit he knew something was amiss, we did various tests and found the problem.He explained things to my son so he could understand and how HE Had to take control of his issue and it made a huge impact.Dr D sees both my sons and I could not be more grateful.
Londonderry, NH |
Scary! Received a summary of visit a few days after my appointment. Confused me with another patient. Listed symptoms I never had, but never mentioned the symptoms I did have. Wouldn't return my call. He Got indignant when I told receptionist- no nurses - what happened. Said I could make an additional appointment to get my symptoms right . Guess his mistakes are my fault?
This patient was not confused with anyone else. Symptoms are recordeed as given to me or as recorded in records released to me from other providers. My average preparation time for new patients is 45 minutes and includes careful review of the patient's own report of their issues. If this patient's assertions are true, I would have violated all of my operating practices. I do not know what the real problem here is as I can not identify the patient. This is totally opposite to my other reviews.

Dr. Detweiler says...

What is unique about my treatment is that I combined the best of both evidence-based medicine and nutrition, along with the 3000-year-old tradition of using herbs as medicine.  I will use whatever set of tools are the least toxic and most appropriate for a given patient.  Statistical humans in a one on one doctor patient relationship are pretty much irrelevant.  Each individual treatment plan is fundamentally an experiment.  This goes for traditional physicians as well, but they do not recognize it.  Many FDA approved medications work on as few as 20 to 30% of patients.  Thus, when one is prescribed such medication.  It is basically an experiment to see if it works for you.  Similarly, the choice of an herbal or nutritional program will necessarily be an experiment.  I have 15 years of experience in the use of mixed medical paradigms and feel very comfortable with the biases that I've developed, but recognize that they are biases.  Most of my decisions are based on current cutting edge research in the immune system's response to the organisms that live in the intestines (the gut microbiome) and its response to what is eaten.  Therefore, I will analyze for these issues in many instances and use that as a guide to begin therapy.  If you have a serious autoimmune disease, such as ulcerative colitis or Crohn's disease.  I am not hesitant to use the most powerful therapy necessary, including anti-TNF alpha antibodies but rather than leave you on these forever once control is obtained, I will try and create a gut environment that allows de-escalation and hopefully removal of these very useful but toxic drugs.

Similarly, chronic reflux issues are many times related to poor gut motility and gut motility is often related to what lives in it and what you eat.  Therefore, looking at these factors may solve an issue where acid blockers have been necessary for many decades.  Western medicine is wonderful for acute injury and highly active inflammatory diseases but is of very little help in the maintenance of chronic disease. 

Lastly, I feel my role is more of a coach that a parent.  For your particular illness.  I will recommend the approach that appears to be best, but it will be up to the individual to carry that out.
