Smoking and Kidneys: Things to Know!
We know smoking hurts the lungs and the heart, but what doesn’t receive as much attention is its effect on our kidneys. Understand that smoking can damage these organs to a very high degree, essentially increasing the risk and severity of kidney disease. Let’s get into how smoking impacts your kidneys, the relationship between smoking and kidney disease, and what you can do to keep them safe.

What do Kidneys do?
Before we dig into how smoking is harmful, let’s quickly remember what your kidneys do. These bean-shaped organs are critical to your overall health. They:
- Get rid of waste and extra fluid from your blood.
- Help regulate blood pressure.
- Balance electrolytes, including sodium and potassium.
- Produce hormones to keep your bones healthy and create red blood cells.
In short, your kidneys are your body’s filtration system, working around the clock to keep things balanced.
Does Smoking Affect Your Kidneys?
The answer is yes. Smoking and kidney disease go hand-in-hand. Smoking is like sending a cocktail of harmful chemicals into your bloodstream, and those toxins can harm your renal health in quite a few ways, such as:
- Decreased Blood Flow: Smoking harms blood vessels throughout the body, including in the kidneys. This damage shrinks the vessels, cutting blood supply to the kidneys. Sick kidneys cannot filter waste properly when they don’t get enough blood. If this continues for a prolonged period, it can lead to chronic kidney disease. There is a positive correlation between smoking and chronic kidney disease.
- Proteinuria: Normal kidneys have filters that stop protein leakage into your urine. Smoking destroys these filters, making them “leaky.” This condition, known as proteinuria, indicates that protein is in your urine, which is an early sign of kidney damage.
- Elevated Blood Pressure: Smoking elevates blood pressure, one of the most common causes of kidney disease. The extra stress from high blood pressure on the filtering units of the kidneys accelerates their failure over time.
- Accelerated Disease Progression: For those who already have kidney disease, smoking can accelerate disease progression and result in the loss of kidney function, leading to kidney failure. This means they might need dialysis or a kidney transplant sooner.
- Increased Risk of Kidney Cancer: Smoking increases the risk of kidney cancer. Studies have found that the risk of developing this type of cancer is higher among smokers than non-smokers.

The Link Between Smoking and Kidney Disease
Smoking is a causative factor in the development and progression of several kidney diseases, including:
- Diabetic Nephropathy: Diabetes can lead to kidney disease, and smoking greatly increases kidney damage in those with diabetes.
- Hypertensive Nephrosclerosis: High blood pressure causes injury to the kidneys, and smoking adds fuel to the fire, leading to hypertensive nephrosclerosis.
- Glomerulonephritis: A group of diseases that affect the filtering units of the kidneys. Smoking can increase the risk of some forms of glomerulonephritis.
- Chronic Kidney Disease: As briefly mentioned in the earlier paragraphs, smoking and chronic kidney disease are positively correlated. Smoking has been known to accelerate chronic kidney disease (CKD) progression by inflicting damage on blood vessels, reducing oxygen to the kidneys, and increasing inflammation.
- Kidney Stones: Smoking and kidney stones are also positively correlated in the sense that consuming tobacco excessively increases the risk of kidney stones by impairing kidney function and reducing urine output. Smoking increases dehydration in the body as well.
The Health Benefits of Quitting
As you must have gathered from the discussion above, smoking and kidneys are fierce enemies. If you smoke, the best thing you can do for your kidney health, as well as your overall health, is to quit. Upon quitting smoking, you will be able to:
- Boost Blood Flow: As your blood vessels begin to heal, blood flow to your kidneys will improve.
- Reduce Proteinuria: Damage to your kidney filters may slow down, causing less leakage into your urine.
- Reduce Blood Pressure: Giving up smoking can lower blood pressure, which helps reduce the load on your kidneys.
- Prevent Kidney Disease: If you are at risk of developing kidney disease, quitting smoking can significantly reduce your chances of developing it.
- Lower Your Cancer Risk: It will reduce your risk of kidney cancer.

Tips for Quitting
Like many things, quitting smoking isn't easy, but it is possible! Some tips that can help include:
- Consult your doctor: They can direct you to resources, support, and medication that can help.
- Consider nicotine replacement therapy: Nicotine patches, gum, or lozenges can help decrease cravings.

- Know your triggers: Understand what causes you to crave cigarettes, and try to find other healthy ways to deal with those triggers.
- Persistence: It takes time and effort to quit, so don’t be disheartened. Celebrate your progress and don’t feel demotivated if you experience a setback.
Your kidneys are essential organs that do a lot of work for you every single day to keep you healthy. Smoking places them under great stress and increases their risk of developing serious kidney problems. Not smoking is one of the best things you can do for your kidneys and to improve your overall health. If you smoke, take that big step today. Your body and your kidneys, in particular, will thank you for it.
