If your kidneys aren't working properly, you could also raise your risk of having a heart attack or stroke.

Youโ€™re a fan of packaged food

Most processed food is chock-full of sodium, which isnโ€™t just bad for your heartโ€”it can also lead to kidney problems. When you’re showing signs you eat too much salt, your body needs to flush the sodiumย out when you pee, and it takes calcium with it. In turn, having too much calcium in your urine increases your risk for kidney stones, says James Simon, MD, nephrologist with Cleveland Clinic. The Dietary Guidelines for Americans recommends capping sodium at 2,300 milligrams a day, but the average American has more than 3,400 milligrams every dayโ€”and some people eat twice that. Take a look at your nutrition label and you might be surprised how quickly sodium can add up. โ€œPeople look at carbs and fat and calories, but they donโ€™t pay attention to sodium,โ€ says Dr. Simon. Make sure you watch out for these 6 warning signs of kidney stones.

Your blood pressure is out of control

High blood pressure is hard on your whole bodyโ€”including your kidneys. โ€œKidneys are basically one big set of blood vessels with urine drains,โ€ says Dr. Simon. โ€œIf you have high blood pressure in your big blood vessels, you have high blood pressure in your smaller blood vessels.โ€ Letting high blood pressure go unchecked could damage theย blood vessels leading to your kidneys, plusย scarย the organs themselves.ย Try using these 31 things to avoid high blood pressure to keepย make sure your levels stay healthy.

You havenโ€™t kicked your smoking habit

If you thought lung cancer was the only reason to put down the cigarettes, think again. One 2012 study found that quitting smoking for 16 or more years cut risk of renal cell carcinoma (the most common form of kidney cancer in adults) by 40 percent. Plus, smoking can damage the blood vessels, and increase your risk of high blood pressure, says Dr. Simon. โ€œItโ€™s another reason smoking is just bad on the body,โ€ he says.

You never drink when youโ€™re thirsty

Contrary to popular belief, you donโ€™t necessarily need to down a full eight glasses of water to keep your kidneys working well. Even with just four to six glasses of water a day, your kidneys are probably fine, says Dr. Simon. But sticking with just a cup or two a day could challenge the organ. Not only will you not have enough water flushing out your system to keep your sodium levels in check, but a dehydrated body will have a harder time keeping its blood pressure up. ย โ€œThe kidney is very sensitive to blood flow,โ€ says Dr. Simon. โ€œIt wonโ€™t like it if you are so dehydrated that your blood pressure drops and the blood flow to your kidneys drops.โ€ You probably wonโ€™t need to worry about that level of dehydration every day, but make sure you drink enough water if youโ€™re exercising a lot or outside on a hot day, he says.

You pop painkillers constantly

Watch out if you take OTC medication for chronic pain. Anti-inflammatory drugs called NSAIDs, which include ibuprofen and aspirin, reduce blood flow to the kidneys, and cause scarring because theyโ€™re directly toxic to the organ, says Dr. Simon. ย Nobodyโ€™s saying you need to suffer through a throbbing headache, but taking NSAIDs too often can up your risk of kidney problems. โ€œThe people at risk are taking them on a daily basis for long periods of time,โ€ says Dr. Simon. But if you already have kidney damage, he recommends avoiding NSAIDs altogether. Check out these other signs your kidneys could beย in trouble.

You assume supplements are safe

Just because a product is marketed as โ€œnaturalโ€ doesnโ€™t mean itโ€™s good for you. โ€œThere are plenty of herbal medicines out there that are harmful,โ€ says Dr. Simon.ย Case in point: A plant-based ingredient called aristolochic acid can be found in โ€œtraditional medicines,โ€ but it can cause scarring in the kidneys. The FDA warns consumers to stay away from products listing Aristolochia, Asarum, or Bragantia on the label, because they probably contain the harmful ingredient. Unless youโ€™re taking a regular multivitamin, always check with your doctor before starting any kind of supplement, warns Dr. Simon. Be especially careful with these 8 vitamins that won’t help your health and are a total waste of money.

Your weight is pushed to the wayside

No surprise here: Extra pounds are hard on your body. Being overweight puts you at higher risk of developing type 2 diabetes, which in turn can in turn up your chances of developing kidney disease. Insulin issues from both type 1 and type 2 diabetes cause inflammation and scarring in the kidneys, says Dr. Simon. โ€œAnybody with diabetes should be getting their kidney function and urine checked on a fairly regular basis,โ€ he says.
