Common Habits that Damage Your Kidneys

We all indulge in bad habits from time to time. We’re only human, after all! And we do our best to avoid bad habits. But what about the ones that we don’t realize are bad? When it comes to preserving our kidneys’ health, we often overlook common habits that seem benign. Could you be harming your kidneys without realizing it? Watch out for these common habits that damage your kidneys!

Common Habits that Damage Your Kidneys

Habit #1: Using Too Many Painkillers

PainkillersWhen it comes to your kidney health, over the counter painkillers present a serious risk for long term damage. The class of drugs which are the main culprit are Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) such as Advil, Motrin, Ibuprofen, and Toradol. I am mindful to warn women who use painkillers frequently often during menstruation (esp woman who bleed for longer periods of time) and also for those with arthritis, joint pain, or chronic headaches.

Both over-the-counter and prescription pain medications can damage and reduce blood flow to the kidneys. Kidney disease caused by prescription and pain medication is called ‘analgesic nephropathy’. Long-term use of certain pain medications, especially at high doses, has a harmful effect on kidney tissue and structures. As many as 1-3% of new cases of chronic kidney failure each year may be caused by overusing pain medication! So try to keep painkillers to a minimum. Your kidneys will thank you.

Habit #2: Smoking Cigarettes

Smoking presents a strong risk factor for many kidney diseases. It’s often a precursor to kidney cancer as well. Diseases that affect the kidneys, such as diabetes and high blood pressure, are also exacerbated by smoking, and smokers are more likely to need dialysis or kidney transplants.

Habit #3: Eating Too Much Sodium

Hold the salt shaker! Adding too much salt at meals or consuming highly processed foods is one of the most common habits that damage your kidneys. Sodium causes water retention and both together will increase the volume of blood flowing through you arteries. Over time, this raises your blood pressure. But why does this matter? Glad you asked!

  • High blood pressure damages the kidneys over time and presents a leading cause of kidney failure.
  • The typical American diet has been estimated to contain more than 3400mg of sodium per day. That figure is substantially higher than the 2,300 mg daily maximum (about a teaspoon of salt) recommended by the FDA.
  • The easiest way to not go over the daily allotment of a “low sodium diet” of 2400 mg per day is to eliminate all processed foods. If you have to ‘open it’, i.e. a can, a packet, a box then don’t eat it. Minimize the salt you add while cooking to a tiny pinch and don’t add extra salt to your food. Give yourself a few months and your BP will correct on its own.

Another way to lower your dietary salt intake is by following the DASH Diet. DASH is an acronym for the Dietary Approaches to Stop Hypertension, and it’s a great place to start learning how to control your blood pressure!

Habit #4: Eating and Drinking Lots of Sugar

Remember that delicious donut you saw as the beginning of this article? Here’s another one for good measure.

Too much sugar is one of the common habits that damages your kidneys

Most of us know that donuts are not healthy four our waistlines–but did you know these high sugar treats hurt your kidneys as well? Eating and drinking lots of sugar is one of the most common habits that damage your kidneys. Obesity and diabetes directly impact how well your kidneys function. In fact, diabetes is the #1 cause of kidney disease in the US. When too much sugar introduces diabetes into the equation, your kidneys no longer filter protein from your system as effectively. That’s why the first sign of diabetes affecting your kidney is protein in the urine.

The FDA recommends 25 grams of sugar a day. Did you know that one can of soda or glass of fruit juice BY ITSELF can push you over this limit? Next time you consider having some OJ for breakfast, check the container for how much sugar you’re drinking. Remember to look at the serving size too!

By cutting back on processed sugars, you will eat less calories and even sodium. Both your kidneys and your waistline will thank you!

#5: Exposure to Contrast Dyes Commonly Used in Imaging

You’ve probably had an MRI or CT scan sometime in your life (or maybe you’ve had many). While getting these scans aren’t really a “habit”, they do start to add up if you have health problems, so it’s important to be wary of them. Doctors often order these tests which require injection contrast dye to better visualize your organs or blood vessels. Contrast dye is also injected during a heart angiogram (heart attack) used to look at the blood vessels supplying your heart. Unfortunately, this contrast dye damages our kidneys and can lead to Acute Kidney Injury or AKI.

AKI results in an abrupt decrease in kidney function and occurs in up to 20% of all hospitalized patients, and over 45% of patients in a critical care setting. If you have normal kidney function, you probably don’t have to worry about contrast dyes. But if you’ve had kidney function issues, it’s something you should discuss with your doctor! Ask them to check your creatinine levels. If they are 1.5 mg/dl or higher, a nephrologist must evaluate you and optimize your kidney function first. If you live in the southern California area, you can call Dr. G’s office to schedule an appointment: (714) 435 • 0150.

Avoiding Common Habits that Damage Your Kidneys

Many of us don’t pay enough attention to our kidney health until something major comes up. Maybe you’ve been diagnosed with CKD or are going through dialysis. It may seem overwhelming to change your lifestyle and give up things you enjoy. But by following these simple tips, you can avoid common habits that damage your kidneys. Every little bit helps!
