From a nationally recognized expert, an exposé of the worst excesses of our zeal for medical testing

Going against the conventional wisdom reinforced by the medical establishment and Big Pharma that more screening is the best preventative medicine, Dr. Gilbert Welch builds a compelling counterargument that what we need are fewer, not more, diagnoses. Documenting the excesse

First-World problems.

If you’ve been led to believe that it’s a good idea to get an annual physical checkup even though there’s nothing wrong with you, you need to read this book. The idea that it’s beneficial that we subject ourselves to tests and screenings, which are judged based on sometimes arbitrarily-set numerical criteria, only to look for problems that do not yet exist or have not shown up yet as symptoms is a pseudo-scientific hoax that is promulgated by those who want to sell you tests

Overdiagnosed: Making People Sick in the Pursuit of Health challenges the current mindset that it's always desirable and beneficial to obsessively screen healthy people for potential illnesses. Dr. Welch describes how actively pursuing illness in healthy people can actually be harmful to the patient.

Why is it bad to discover that people have diseases they don't know about and that have yet to create any symptoms? A few reasons are:
1) The medical-industrial complex continually lowers the numbers

A very clear, well-reasoned, reader friendly, evidence-based argument for the view that preemptively hunting for health problems in asymptomatic people through routine screenings and tests, and lowering diagnostic thresholds (as has been done with high blood pressure, cholesterol, and diabetes), is not in the best interests of the vast majority of people. Many such early-intervention strategies do not lower the number of deaths from those diseases, result in false positives and overtreatment, an ...more

More than 35 years ago my father died, too young, from pancreatic cancer. I learned at a young age that there were benign tumors and malignant tumors but I've always held the belief that if I have cancer in my body I want it removed. And sooner rather than later. And I would want to know as soon as possible.

Over the years I've heard that there were controversies about screening for and treating prostate and breast cancer. (These are discussed in the book and presented very well.) Who wouldn't w

This book is a lot better and more accurate than you would think. I happened upon it at the library. After looking at it for a week I was super bored and read it. Could not put it down! It explains how diagnostic tests have shifted (high cholesterol is now 200 and over where before it was 240 and over) after studies (paid for by drug companies-often) determined a lower threshold was needed. It also discusses how if you get enough tests you are bound to find something and that sometimes the treat ...more

Dr. Welch was involved in an experiment in which a group of men who had had heart attacks were split into two groups, one of which was equipped with devices to measure irregularities & the other which was given the usual regular checkups. The experiment was discontinued when the researchers found that the device-equipped group received more treatment & died in greater numbers. This got the author looking for similar medical treatment phenomena.

The biggest fault of this book is probably the tendency of the author to repeat himself rather a lot, both in explaining what he means and what he does not mean to say. But you can understand that because of the severe risks to his readers of misinterpretation of his message, or to himself if others looking to sue him were to misconstrue what he is saying.
Welch has an important point to make - I won't bore you with a restating of what that point is, as you will have read about it already to get

Underwhelming. The entire book demonstrated how over-diagnosis is harmful when seeking out diseases that are asymptomatic. Welch, also dismisses the financial incentives within the market to seek diagnosis and to treat early. Lastly, he was completely silent as to how health reform provisions (if the Supreme Court doesn't shut it down) will actually curb over-diagnosis and realign incentives towards health promotion and prevention.

Everyone should read this book, but I fear that few will. Partly because it is perceived as a difficult topic. No worries there: Dr. Welch and his co-authors make this as easy and straightforward a read as possible. Even if you barely passed high school biology or math, you'll have no problems here: the science is simple, the statistics are very clearly explained.

Another reason folks might not read this is that they are comfortable delegating their personal health decisions to physicians. The fa

'Overdiagnosed' is, without a doubt, an important book. It convincingly shows that if we look harder for a disease, we find more "abnormalities" but we're not preventing any deaths. Instead, the more people are subjected to unneccesary medical procedures, which can be just scary, expersive and annoying but also debilitating or even lethal.
The authors explains how this happens with great clarity. Let's say, as an example, that each year a hundred women find a lump in their breast. They go and se

I found myself feeling dubious about some of the claims. I also found myself wishing for more detail. Basically, the concept is that doing hunting expeditions for diseases isn't a good idea. He is all for what he calls diagnostic screening: if the patient goes to the doctor with a lump or something. He is very opposed to screening being done routinely and explains why in convincing detail. I'm just not completely convinced. My father in law was diagnosed with colon cancer after getting a toilet ...more

If you are interested in America's health care system, you should read this book. The authors are practicing physicians and bring both real world experience and an MD level understanding of clinical trials. We are moving from treating sick people that have definite symptoms to looking at healthy people with no symptoms in the hope that "early detection" will prevent sickness. With the advent of MRIs and CT scans, we are able to see much more than ever before. The cut offs for diagnosing high blo ...more

Overdiagnosed : Making People Sick in the Pursuit of Health (2012) by H Gilbert Welch describes how diagnosing people without symptoms is a serious problem with modern health systems.

Over diagnosis is definitely a problem. Prostate screening and over diagnosis is accepted by many, perhaps most medical researchers as a serious problem. Screening in other areas is also seen as something that can cause real harm. Making abnormal physical characteristics diseases is definitely unwise. The incentives

After hearing Dr. Welch give this presentation I immediately went out and got the book. He does a convincing way of presenting data to support his premise without putting one to sleep. I feel his conclusions are well reasoned and logical and appreciate his suggestions regarding 'what now'. You can see his presentation on You Tube If this message resonates with you then I'd suggest you read The End of Illness and Our Daily Meds. Both books lend themselves ...more

This book was really interesting considering the direction American healthcare is taking, namely spending more and more money but doing nothing to actually improve quality of life. I mainly picked it up because there was a chapter about ultrasound and fetal monitoring...turned out this was the shortest chapter but worth reading. The author had a degree in economics before going to med school so his perspective was unique. My main complaint is how frequently the author repeated catch phrases...we ...more

I'd seen a few of Dr. Welch's interviews online (and enjoyed them) before reading this, and as a patient of Dr. John McDougall I was already well versed in the insidious risks of overdiagnosis - and have been an unwitting victim of it myself several times. Dr. Welch's book is an important read - because truly informed consent is so often lacking, while aggressive marketing of highly questionable "early detection" testing and other procedures is pervasive. I liked Dr. Welch's eloquent summary on ...more

I have experienced overdiagnosis. It caused me emotional and mental stress (high) and financial stress (moderate) for an unnecessary surgery. The zeal for early diagnosis and treatment did not serve me well and I will think hard before going down that path again. This book was excellent to open my eyes to a different paradigm and gain more balance in how to approach my health. I really recommend it. I enjoyed the Audible version.

This book presents some interesting ideas, and it certainly made me feel like a Monday-morning quarterback about some of my recent health decisions. Some of the writing feels a bit redundant, but dividing the chapters by conditions helps to keep things moving. A solid 3 1/2 stars.

Really good book to help negotiate one of the many areas of difficult decisions regarding healthcare. Doesn't just give you data, but promotes different perspectives on how to analyze and interpret the data, and the difference between good and flawed data.

The want to know versus the need to know. Nicely balances the concerns about over testing with the benefits of early detection. Always a two edged sword

A timely look at how the medical profession is over diagnosing patients. It is time to start questioning why some tests are really necessary.

Interesting views on routine testing, and worth pondering and revising. But if taken too literally, seems like dangerous advice.
I'd heard a lot about the contents of this book, so I wanted to read it for more depth.

It's not surprising that we find more health anomalies if we look for them. What surprised me was the moving of the bar for anomalies, which, although not mentioned in the book, seems to be coincident with the release of new and profitable drugs.... hmmmm... I'm not claiming a correlation or a causation, it's just an observation.

While this book delivers what I believe to be a very important message, it makes its point within the first 7 or 8 chapters. After that it simply becomes repetitious. I found it well worth reading for those initial chapters, but I found myself skimming the next few chapters and not reading the rest, except to verify that they gave so little new information.
This book explains the risks of screening for abnormalities in healthy people. The downsides of over diagnosis are explained via anecdotes as well as with statistics.

Bottom line: worth the read.

Would explain a lot about why we spend so much on medical care yet do not have the best health in the world. The author reviews several diseases (mainly cancers) and asks whether they are being overdiagnosed. The principal hypotheses the author makes behind his analysis are:

- Doctors have never really operated in a scientific manner. Since they often do not have the luxury of denying patients treatment and seeing whether they get better anyway, they never really know whether treatment was effect

The book is worth reading. Dr. Welch does a good job making his points. He and others who share his zeal have contributed to public awareness of a problem that has bothered medical professionals for sometime. The use of many cancer-screening tests can lead to the diagnosis of tumors that may never have been harmful had they remained undetected. In this situation we say the cancer is overdiagnosed and the patients overtreated. Welch has many excellent good points to make. Unfortunately, he, and t ...more

Dr. Welch sheds light upon a controversial, lesser-known corner of medicine -- over-diagnoses. Although it is a term rarely used in today's medical world, he (and others) are bringing up issues in the U.S. healthcare system of how not everything that we pursue in medicine may be beneficial to the patients, physicians, and the system as a whole. Today's medicine is all about catching diseases early, even before it starts. and testing and treating more. This can bring more income, prevent malpract ...more
