Stairs, Sugar, and Your Heart: Medicine Caught Lying to Women
There is a peculiar kind of courage in admitting that medicine got something wrong — not in a peripheral way, but at the very centre of how it reads the human body.
Stairs, Sugar, and Your Heart: Medicine Caught Lying to Women
There is a peculiar kind of courage in admitting that medicine got something wrong — not in a peripheral way, but at the very centre of how it reads the human body. The announcement from leading cardiovascular groups that the world now has its first universal definition of a heart attack is not a bureaucratic update. It is a confession. For decades, the diagnostic thresholds used to identify heart attacks were built almost entirely on data from men. Women, who often present with different symptoms and different biological markers, were measured against a body that was never theirs. Many were sent home. Some did not come back.
The new definition introduces sex-specific diagnostic thresholds and reclassifies several causes of cardiac events that were previously overlooked — causes more common in women. What this means practically is that a woman sitting in an emergency room in Valletta, or Geneva, or anywhere, now has a marginally better chance of being seen accurately. Not perfectly. But better. That matters.
Set beside this, two other findings arrive with the quiet insistence of things that were always true. The first: drinking at least one sugar-sweetened beverage daily may more than double the risk of stomach cancer. Not a gentle nudge toward moderation — a doubling. The mechanism is still being studied, but the pattern across research cohorts is consistent enough to take seriously. The second: taking the stairs, in a large multi-study analysis, measurably reduces the risk of cardiovascular disease and early death. Not running. Not a gym membership. Stairs.
What strikes me about these three pieces of research together is how unglamorous they are. No new drug. No intervention requiring a prescription or a referral or a waiting list. The stairs. Less sugar. A diagnostic tool that finally accounts for half the population. The biggest gains in public health have always looked like this — small corrections to things we normalised without thinking.
I grew up moving between cities where the staircases were different in every apartment — steep and spiral in Geneva, wide and colonial in Nairobi, brutally efficient in Singapore. What I remember is that my father always took the stairs. He never explained why. He just did. I assumed it was habit. Now I think it was instinct.
One thing you can do tomorrow: swap one sugary drink — juice, soda, flavoured coffee — for still water with something added: mint, cucumber, a slice of lemon. Not forever. Just tomorrow. See how that feels.
