Does Diverticulitis Need Antibiotics?

Over the past several years, there has been an important change in how diverticulitis is treated.  This topic sentence may seem out of place on this blog which is largely a site for commentary.  This is not a site that discusses medical breakthroughs on the treatment of constipation or heartburn.  But diverticulitis does offer a commentary angle, if you will read further.

Decades of teaching and dogma have informed the medical profession that diverticulitis is a localized infection of the colon.  Diverticula, or pouches, are weak points in the large bowel.  If a tiny puncture develops at one of these sites, some stool can leak out contaminating the sterile abdominal cavity.  An infection develops which, of course, needs to be treated with antibiotics.

Indeed, for most of my medical career, every case of diverticulitis I encountered was treated with antibiotics.  In most cases, these patients recovered fully.  This observation may be Truth #1. 

Just because a patient recovers with treatment, doesn’t prove that the treatment was responsible.

If a patient is suffering from a cold, which is nearly always caused by a virus, is given antibiotics and recovers, the patient would have recovered anyway as antibiotics aren’t effective against viruses.


It can be a great challenge to leave the herd.

Several years ago, studies demonstrated that certain diverticulitis cases fully recovered without antibiotics.  These folks healed themselves.  This was a paradigm shift in diverticulitis management. We physicians have known for decades that diverticulitis could heal spontaneously since many of our patients would relate prior episodes of this illness for which they did not seek medical attention.  This observation may be Truth #2.

Diverticulitis may not be an infectious disease.

Of course, diverticulitis could still be an infection that is cured by a person’s own natural immunity, without drugs.  But it is also possible that there is no infection involved.  Perhaps, diverticulitis is simply a form of non-infectious colitis, such as Crohn’s disease or ulcerative colitis, which has no known cause.  For all of these decades, doctors simply accepted without challenge that antibiotics were necessary.

I should note that when diverticulitis is complicated or severe, experts continue to advise antibiotics.  

So, here’s the commentary you’ve been patiently waiting for.  Here is Truth #3.

Just because doctors have always done something one way, doesn’t mean it’s correct.

How many untested and unproven practices do we all do in our own lives simply be cause we’ve always done it this way?  This is not a surefire way to make progress.  All it takes is one curious person to shake things up.

  1. Thanks, Michael. Changing long standing habits is hard. What do you now do with a patient with classic signs and symptoms of diverticulitis - LLQ pain and tenderness, fever, elevated white cell count?

Becoming a Part-Time Physician

Next month my schedule will change.  I will henceforth be off on Fridays with my work week truncated to Monday through Thursday.   I am excited to be enjoying a long weekend every weekend.  And while the schedule change is relatively minor, this event does feel like an important career moment for me.  It is the first step on a journey that will ultimately lead beyond my professional career.  It is this recognition that makes this modest schedule modification more significant than one would think it deserves.  As some readers know,   my current employed position has been a dream job for me.   Prior to this, I was in a small private practice, which I loved, but was much more challenging professionally and personally.   My partner and I ran the business.   Working nights, weekends and holidays were routine for decades.   On an on-call night, if I slept  through until morning, I felt as if I had won the lottery.   And w...

When Should Doctors Retire?

I am asked with some regularity whether I am aiming to retire in the near term.  Years ago, I never received such inquiries.  Why now?   Might it be because my coiffure and goatee – although finely-manicured – has long entered the gray area?  Could it be because many other even younger physicians have given up their stethoscopes for lives of leisure? (Hopefully, my inquiring patients are not suspecting me of professional performance lapses!) Interestingly, a nurse in my office recently approached me and asked me sotto voce that she heard I was retiring.    “Interesting,” I remarked.   Since I was unaware of this retirement news, I asked her when would be my last day at work.   I have no idea where this erroneous rumor originated from.   I requested that my nurse-friend contact her flawed intel source and set him or her straight.   Retirement might seem tempting to me as I have so many other interests.   Indeed, reading and ...

Will Smarter Lawyers End Frivolous Lawsuits?

How do you know if a lawyer is any good?  Of course, they've all passed the bar, but now their profession is lowering it.  While most of us strive for excellence, and raise our children to value this virtue, prominent legal educators are establishing a new quality intitiative for their profession.  Who says that lawyers can't reform themselves?  Perhaps, we physicians can follow their bold example and raise the credentials of our pre-medical students.  I’ll present the facts. You be the judge. I have written a dozen posts on tort reform on this blog, which always generate spirited and adversarial retorts from attorneys and their supporters. They accuse me and other tort reform advocates of carrying water for insurance companies. They repeatedly point out that I know nothing about the legal system and are unqualified to opine on its flaws. They deride me when I argue that effective tort reform would reduce the practice of defensive medicine, despite the re...
