The cigarette may be disappearing from the lives of the young. But the kidneys may not be getting a break just yet. For generations, smoking and alcohol were familiar villains in health warnings. Ci******es were linked to lung and heart disease; excessive alcohol to liver damage. The kidneys rarely received the same attention, even though they filter waste from the blood, regulate fluids and electrolytes and help control blood pressure around the clock.
Now the lifestyle map is changing.
Gen Z is often seen as more health-conscious than previous generations. Younger adults in several countries are smoking less, while some are also drinking less or choosing to delay alcohol. Fitness trackers, nutrition apps and social-media wellness content have made health information almost impossible to escape. Could that give Gen Z healthier kidneys as it ages? Possibly — but only if avoiding the old risks is accompanied by healthier everyday habits. Because while the cigarette may be disappearing, a different set of kidney risks may be quietly taking its place.
The kidney damage behind a cigarette
Smoking is usually thought of as a lung problem. The kidneys, however, are highly dependent on healthy blood vessels. To***co exposure can contribute to vascular damage, oxidative stress, inflammation and high blood pressure. It is also associated with protein appearing in the urine — proteinuria — an important marker of kidney injury. The concern becomes greater when smoking is combined with diabetes or hypertension, two major drivers of chronic kidney disease. A nephrologist explains that smoking can worsen vascular injury and blood-pressure control and may accelerate kidney damage, particularly in people who already have diabetes, hypertension or established kidney disease. And there is a reason kidney damage can remain unnoticed for years: the kidneys are remarkably quiet when they are struggling. A person can feel perfectly healthy while kidney function is gradually declining.
