Complications
Why this?
I started this book in a slightly accidental way after stumbling across a quote on KeyHero that loosely gestured at medicine as something deeply uncertain, almost anti-scientific in the way people usually imagine science. That idea stuck with me, because medicine does not really behave like a clean science at all; it feels more like a massive, evolving machine where human technical prowess keeps redefining itself just enough to move forward without ever fully understanding what it is doing. That tension alone was enough to pull me in.
The book also has its own Wikipedia page, which already signaled that it had some cultural weight, and it felt almost like an antithesis to figures such as B. M. Hegde, whose views on medicine I have encountered before. I am not sure where I land in that comparison yet, but it felt like fertile ground for new ways of thinking. On top of that, the author having served in the Biden administration added another layer of intrigue, suggesting that these ideas do not just live in operating rooms or books, but leak into policy and governance as well.
Overall Thoughts
This is probably the first non-fiction medical book that genuinely kept me thinking long after I put it down and forced me to develop new perspectives, and in that sense it played a role similar to The Scientific Edge in how it quietly reshaped my thinking, except this time by opening the door to the world of medicine. I originally thought Robert Sapolsky’s Why Zebras Don’t Get Ulcers would be that entry point, but it wasn’t, and this book ended up being far more interesting and unsettling in the right ways. Unless I were a doctor, I doubt I would have ever reached this intellectual stop on my own, which is part of what makes the experience so striking, and reading it in a non-linear, essay-like manner probably helped me engage with the ideas more deeply rather than consuming them passively.
The chapter on consent in medicine stood out as especially crisp and contemplative, and the statistic about how many people do not want to make decisions themselves but instead rely entirely on doctors felt deeply real and uncomfortable, because I honestly do not know how I would think clearly in situations like that either. I also found myself thinking about System 1 and System 2 styles of reasoning in medical decision-making, and after discussing it with ChatGPT and being pointed toward Daniel Kahneman’s work on noise, it was oddly reassuring to realize that these questions have already been rigorously examined by people far smarter than me. The storm and ice cube analogy in the book captures this perfectly, where no two storms are ever the same, an ice cube always melts in a predictable way, and most medical cases live somewhere in the messy space between those extremes, which I found genuinely insightful. I think I have covered most of what I found valuable in the book, and for the rest, I am happy to simply leave the quotes behind for anyone who wants to explore further.
Chapter Notes
| Chapter | Learnings |
|---|---|
| Education of a Knife | 1. Should resident surgeons be allowed to work on dangerous operations? If not, how exactly are they supposed to learn? The book refuses to give a comfortable answer, and that’s the point. 2. Medicine constantly tries to balance what is technically possible with what is ethically necessary—and those two are very often not aligned. |
| The Computer and the Hernia Factory | 1. Hyper-specialization—turning surgeons into near-assembly-line experts for procedures like hernia repair—can reduce error rates to historic lows. 2. But this kind of efficiency comes at a cost: it doesn’t build broad judgment or adaptability, which might be dangerous once reality stops behaving like a factory. |
| Nine Thousand Surgeons | 1. Surprisingly fascinating look at a scientific personality attending a large medical conference. Watching “impossible” surgeries performed live, while the audience is entertained and pampered, is honestly wild. 2. The author says he feels at home among nine thousand surgeons because of the shared conversational rhythm and mutual understanding.That’s interesting, cause that’s what I’m feeling currently in the tech world. |
| When Good Doctors Go Bad | 1. This chapter feels like a real-world episode of House, minus the clever editing. Doctors are human, and sometimes they break under pressure. 2. The statistic about how rarely doctors report other doctors feels uncomfortably real—peer pressure doesn’t disappear just because the stakes are life and death. 3. Depression and mental health issues are serious and widespread in medicine, and pretending doctors are emotionless clinical machines only makes things worse. |
| Full Moon Friday the Thirteenth | 1. I liked the author’s banter about medical practitioners being rigorous scientists who still carry strange quirks and superstitions. That mix feels very human—and very honest. 2. The dive into moon-based rhythms was unexpectedly hilarious. It’s a reminder that even hyper-rational professions aren’t immune to pattern-seeking and narrative addiction. |
| The Pain Perplex | 1. It’s unsettling that pain—something so fundamental—remains such a debated and unresolved problem in medicine. 2. Is pain located in the nerves or constructed in the brain? Phantom pain, in particular, breaks simplistic models and forces deeper questions about perception and reality. This chapter was genuinely fascinating. |
| Crimson Tide | 1. A short but intriguing chapter about a woman who controlled blushing through surgery. It reminded me strongly of phantom pain and mirror box therapy, especially the work of Ramachandran that first fascinated me years ago. 2. Even after eliminating the physical symptoms, impostor syndrome pushed her to resign and pursue a different career. The story quietly exposes how psychological narratives can overpower biological fixes. |
| The Man Who Couldn’t Stop Eating | 1. Learned about Roux-en-Y gastric bypass (RYGB) and how, in the early 2000s, it was seen as a near-miraculous solution to obesity. The scale and speed of its adoption are genuinely shocking. 2. The chapter makes a strong case that eating disorders aren’t purely mental or purely physical—they live in the interaction between both. Some of the quotes here stuck with me long after finishing the chapter. 3. I really like the author’s relentless curiosity. He doesn’t settle for surface explanations; he talks to people, gathers evidence, and keeps asking why things work—or don’t. 4. The ending, where the patient reflects on God and control after the surgery, feels like the perfect unsettling note to end on. Not preachy—just honest. |
| Whose Body Is It Anyway | 1. A necessary and uncomfortable discussion about consent, autonomy, and the doctor–patient relationship, grounded in real cases rather than abstractions. 2. The story of the elderly woman who survived despite medical pessimism is pure gold. It captures the uncertainty, humility, and occasional grace of medical practice. |
| The Case of the Red Leg | 1. This chapter is dense with insight. It made me understand how doctors actually think under uncertainty, not how we imagine they think. 2. Despite everyone estimating less than a 5% chance of necrotizing fasciitis, the intuition wouldn’t go away—and it turned out to be correct. The tension between statistical reasoning and gut feeling is genuinely terrifying. 3. Consulting multiple specialists bought time and clarity. It wasn’t clean or elegant, but it worked, which is often how real problem-solving looks. 4. The use of hyperbaric oxygen therapy felt almost science-fictional. Sometimes you really do have to stop and appreciate how far applied science has come. 5. I also liked that the author followed up with patients long after discharge. What happens outside the hospital is often the real story, and the fact that he cared enough to check matters more than it first appears. |
Quotes
It is an imperfect science, an enterprise of constantly changing knowledge, uncertain information, fallible individuals, and at the same time lives on the line. There is science in what we do, yes, but also habit, intuition, and sometimes plain old guessing. The gap between what we know and what we aim for persists. And this gap complicates everything we do.
The Senning procedure allowed children to live into adulthood. The weaker right heart, however, cannot sustain the body’s entire blood flow as long as the left. Eventually, these patients’ hearts failed, and although most made it to adulthood, few lived to old age. Then, by the 1980s, a series of technological advancements made it possible to do a switch operation safely. It rapidly became the favored procedure. In 1986, the Great Ormond Street surgeons made the changeover, and their report shows that it was unquestionably a change for the better. The annual death rate after a successful switch procedure was less than a quarter that after the Senning, resulting in a life expectancy of sixty-three years instead of forty-seven. But the price of learning to do it was appalling. In their first seventy switch operations, the doctors had a 25 percent surgical death rate, compared with just 6 percent with the Senning procedure. (Eighteen babies died, more than twice the number of the entire Senning era.) Only with time did they master it: in their next hundred switch operations, just five babies died. As patients, we want both expertise and progress. What nobody wants to face is that these are contradictory desires. In the words of one British public report, “There should be no learning curve as far as patient safety is concerned.” But that is entirely wishful thinking.
Doctors belong to an insular world—one of hemorrhages and lab tests and people sliced open. We are for the moment the healthy few who live among the sick. And it is easy to become alien to the experiences and sometimes the values of the rest of civilization. Ours is a world even our families do not grasp. This is, in certain respects, the experience of athletes and soldiers and professional musicians. Unlike them, however, we are not only removed, we are also alone. Once residency is over and you’ve settled in Sleepy Eye or the northern peninsula of Michigan or, for that matter, Manhattan, the slew of patients and isolation of practice take you away from anyone who really knows what it is like to cut a stomach cancer from a patient or lose her to a pneumonia afterward or answer the family’s accusing questions or fight with insurers to get paid.
This is, after all, a world with studies on almost anything you could think of.
The limitations of this mechanistic explanation, however, have been apparent for some time. During the Second World War, for example, Lieutenant Colonel Henry K. Beecher conducted a classic study of men with serious battlefield injuries. In the Cartesian view, the degree of injury ought to determine the degree of pain, rather like a dial controlling volume. Yet 58 percent of the men—men with compound fractures, gunshot wounds, torn limbs—reported only slight pain or no pain at all. Just 27 percent of the men felt enough pain to request pain medication, although such wounds routinely require narcotics in civilians. Clearly, something that was going on in their minds—Beecher thought they were overjoyed to have escaped alive from the battlefield—counteracted the signals sent by their injuries. Pain was becoming recognized as far more complex than a one-way transmission from injury to “ouch.”
“Man is the only animal that blushes,” Mark Twain wrote. “Or needs to.”
Yet very few people, whether heavy or slim, can voluntarily reduce their weight for long. The history of weight-loss treatment is one of nearly unremitting failure.
The one group of human beings that stands in exception to this doleful history of failure is, surprisingly, children. Nobody would argue that children have more self-control than adults; yet in four randomized studies of obese children between the ages of six and twelve, those who received simple behavioral teaching (weekly lessons for eight to twelve weeks, followed by monthly meetings for up to a year) ended up markedly less overweight ten years later than those who didn’t; 30 percent were no longer obese. Apparently, children’s appetites are malleable. Those of adults are not.
We are a species that have evolved to survive starvation, not to resist abundance.
“I had a serious problem and I had to take serious measures,” he said. “I think I had the best technology that is available at this point. But I do get concerned: Is this going to last my whole life? Someday, am I going to be right back to square one—or worse?” He fell silent for a moment, gazing into his glass. Then he looked up, his eyes clear. “Well, that’s the cards that God gave me. I can’t worry about stuff I can’t control.”
I am sure I can figure out what’s wrong with her, but, if you think about it, that’s a curious faith. I have never seen this woman before in my life, and yet I presume that she is like the others I’ve examined. Is it true? None of my other patients, admittedly, were forty-nine-year-old women who had had hepatitis and a drug habit, had recently been to the zoo and eaten a Fenway frank, and had come in with two days of mild lower-right-quadrant pain. Yet I still believe. Every day, we take people to surgery and open their abdomens, and, broadly speaking, we know what we will find: not eels or tiny chattering machines or a pool of blue liquid but coils of bowel, a liver to one side, a stomach to the other, a bladder down below. There are, of course, differences—an adhesion in one patient, an infection in another—but we have catalogued and sorted them by the thousands, making a statistical profile of mankind.
So push. Your patient is getting ready to walk out the door. You could stop her in her tracks and tell her she’s making a big mistake. Give her a heavy speech about cancer. Point out the fallacy in supposing that three negative biopsies proves that the fourth one will be negative as well. And in all likelihood you’ll lose her. The aim isn’t to show her how wrong she is. The aim is to give her the chance to change her own mind.
The core predicament of medicine—the thing that makes being a patient so wrenching, being a doctor so difficult, and being a part of a society that pays the bills they run up so vexing—is uncertainty. With all that we know nowadays about people and diseases and how to diagnose and treat them, it can be hard to see this, hard to grasp how deeply uncertainty runs. As a doctor, you come to find, however, that the struggle in caring for people is more often with what you do not know than what you do. Medicine’s ground state is uncertainty. And wisdom—for both patients and doctors—is defined by how one copes with it.
One study found that although 64 percent of the general public thought they’d want to select their own treatment if they developed cancer, only 12 percent of newly diagnosed cancer patients actually did want to do so.
The odds—the seeming randomness—were what disturbed her most. “First, they say the odds of you getting this are nothing—one in two hundred fifty thousand,” she said. “But then I got it. Then they say the odds of my beating it are very low. And I beat those odds.” Now, when she asked us doctors if she could get the flesh-eating bacteria again, we told her, once more, the odds are improbably low, one in two hundred fifty thousand, just like before. “I have trouble when I hear something like that. That means nothing to me,” she said. She was sitting on her living room sofa as we talked, her hands folded in her lap, the sun rippling through a bay window behind her. “I don’t trust that I won’t get it again. I don’t trust that I won’t get anything else that’s strange or we’ve never heard of, or that anyone we know isn’t going to get such a thing.”
