The Seven Medical Sins — first laid out by the sharp-tongued British physician Richard Asher in 1949 — still haunt hospital corridors, outpatient clinics, and Zoom consults today. They are not dramatic scandals or rare malpractice headlines. They are the quiet, everyday failings that turn good doctors into slightly less good ones, and patients into numbers, puzzles, or inconveniences.
1. Obscurity
If you can’t explain it simply, you probably don’t understand it either.
Dr. Patel stands at the bedside of a worried 68-year-old man.
“Your echocardiography demonstrates mild left ventricular diastolic dysfunction with preserved ejection fraction, likely secondary to hypertensive heart disease, and we’ve noted some non-specific ST-T wave changes…”
The patient blinks. His daughter leans in. “So… is his heart failing or not?”
Dr. Patel pauses, then tries again, softer: “Your heart muscle is a bit stiff from years of high blood pressure. It still pumps well, but it doesn’t relax properly between beats. That’s why you’re short of breath sometimes. We’re going to treat the blood pressure better and watch it carefully.”
The man’s shoulders drop. Understanding is medicine’s first kindness. Obscurity is its first betrayal.
2. Cruelty
Performing procedures that hurt more than they help.
“Just one more blood draw,” the intern says cheerfully at 3 a.m.
Mrs. Alvarez, 82, has already been stuck five times today. Her arms look like a battlefield. The labs will not change management overnight.
Later, the consultant asks, “Why did we do that?”
The intern shrugs. “Protocol.”
Cruelty is rarely sadism. It is usually the absence of the question: Is this worth the pain right now?
3. Bad Manners
The simple failure of courtesy.
A junior doctor barrels into the room without knocking, eyes locked on the laptop.
“Mrs. Khan? Yeah, your potassium is high again. We’ll give you some resonium. Any questions?” He is already halfway out the door.
Mrs. Khan’s son calls after him: “She doesn’t speak English well. Can you just… look at her when you talk?”
Bad manners are free to fix. A greeting, eye contact, sitting down for thirty seconds — these cost nothing and restore dignity faster than any drug.
4. Overspecialisation
Treating the organ while forgetting the person who owns it.
The cardiologist reviews the angiogram. “Beautiful stents. Coronary arteries look great.”
The nephrologist notes the rising creatinine. “We’ll adjust the meds.”
The endocrinologist tweaks the insulin.
No one notices that Mr. Okonkwo has not eaten properly in three days because he is grieving his wife, or that he can no longer afford the taxi to all these separate clinics.
The body is not a collection of specialist territories. It is one scared human being trying to stay alive.
5. Love of the Rare
The intoxicating pull of the exotic case.
At the morning meeting the registrar’s eyes light up. “This could be Whipple’s! Or maybe adult-onset Still’s! We should do the full work-up.”
The consultant, older and quieter, asks, “What’s the most likely diagnosis?”
“Well… community-acquired pneumonia, I suppose.”
“Then treat that first. The zebras can wait until the horse is fed.”
Chasing rarities is thrilling. Missing the common thing while you do it is dangerous.
6. Common Stupidity
Blind obedience to protocols and algorithms at the expense of thought.
“The sepsis pathway says fluids and broad-spectrum antibiotics within the hour,” the nurse announces.
The patient is an 89-year-old with advanced dementia, recurrent aspiration, and a clear advance directive against aggressive treatment.
The young doctor hesitates, then says, “But the pathway…”
An older colleague places a hand on his shoulder. “Pathways are tools, not commandments. Use your brain. Use your heart. Then use the pathway.”
Algorithms are excellent servants and terrible masters.
7. Laziness
The quiet refusal to dig deeper.
“I’ve already looked at the notes from last admission,” the doctor mutters, scrolling quickly.
He misses the single line written three months earlier by a careful GP: “Patient reports new nocturnal symptoms — ?cardiac.”
Later that week the patient has a major event that might have been prevented.
Laziness is not always dramatic. Sometimes it is just the decision not to open one more tab, not to phone one more colleague, not to sit with uncertainty a little longer.
These seven sins are still relevant because medicine remains a human craft practised by tired, clever, imperfect people under pressure. The antidote is not perfection. It is the daily, slightly inconvenient decision to be clear, kind, courteous, whole-person, humble about rarity, thoughtful beyond protocols, and willing to do the extra bit of work.
Asher wrote them as a warning. The best doctors still keep them as a mirror.
