Our approach to chronic kidney disease

According to the National Kidney Foundation, more than 1 in 7 U.S. adults are estimated to have chronic kidney disease (CKD) and 90% of them do not know it.

Kidney disease occurs if your kidneys are no longer able to complete the many important jobs they do to keep your body in a healthy balance.

The main function of the kidney is to remove waste and extra fluid from the body through the urine. In the presence of kidney disease, the kidneys are no longer able to reduce the waste, causing a buildup of harmful substances in the body. Kidney Disease is considered chronic when the kidneys are no longer able to do this important job, generally for 3 months or more.

Other important functions of the kidneys are:

• helping to make red blood cells
• balancing important minerals in your body
• helping maintain your blood pressure
• keeping your bones healthy

Occasionally, a condition can occur where the kidneys are suddenly not able to filter waste products from the blood, referred to as acute kidney injury (AKI); this can happen in a few hours or a few days and is usually a condition that can be reversed.

Causes of chronic kidney disease

There are several risk factors that can lead to chronic kidney disease:

• diabetes
• high blood pressure
• heart disease
• obesity
• family history of CKD or kidney failure
• history of acute kidney injury (AKI)
• advancing age (over 60)
• smoking/tobacco use

Knowing your risk level is important, you should ask your primary care/family medical provider to evaluate you for kidney disease if you have any of the risk factors above.

Treatment and care of chronic kidney disease

WellSpan’s expert team is here to help you take care of you and keep your kidneys healthy. They work with you to keep the CKD from getting worse and reduce your risk of other health problems, such as high blood pressure and cardiovascular disease.

While there’s no cure for CKD, you can take steps to preserve your kidney function, so they work as long as possible.

If you have reduced kidney function:

• Make and keep your regular healthcare provider visits to monitor your kidney health.
• Manage your blood glucose (sugar) if you have diabetes.
• Manage your blood pressure levels.
• Avoid taking painkillers and other medications that may make your kidney disease worse.
• Follow a kidney-friendly diet. Dietary changes may include limiting protein, eating foods that reduce blood cholesterol levels, and limiting sodium (salt) and potassium intake.
• Don’t smoke.
• Exercise/be active on most days of the week.
• Stay at a weight that’s healthy for you.

We recommend you get screened for CKD if you’re over 60 and have any of the following:

• diabetes
• high blood pressure
• heart disease
• a family history of kidney failure
• advancing age 60yrs +

CKD is diagnosed using two simple tests:

• A blood test known as an eGFR Estimated Granular Filtration Rate.
• A urine test known as uACR or Urine Albumin Ratio.

Both tests are necessary to correctly diagnosis kidney disease. If the results of your eGFR are below 60 and/or the results of the uACR is over 30 for three months or more, you have chronic kidney disease.

Managing your diet to keep your kidneys healthy

It is recommended that you work with a registered dietitian to learn about healthy foods that can help keep your kidneys healthy and avoid overworking them. Ask your provider to refer you to the WellSpan Nutrition Services team.

Here are some important key takeaways to help manage your kidney health:

• Reduce sodium (salt) intake.
  Increased amounts of salt can cause your blood pressure to rise by holding onto excess fluid in your body. Avoid processed foods, choose products labeled low or no sodium, and reduce the amount of added salt you use on your food. Instead, use herbs and spices to enhance flavor.
  For more guidance, view the Sodium guide (DASH eating plan).
• Be mindful of protein intake.
  High levels of protein can make your kidneys work harder to remove waste.
  Learn more about choosing the right types and amounts of protein in the Protein food guide.
• Limit phosphorus and potassium intake.
  Too much phosphorus and/or potassium can affect heart and bone health. Common foods high in potassium include bananas, oranges and potatoes. Foods high in phosphorus include meat, poultry, fish and nuts.
  You can review food choices in more detail using the Phosphorus food guide (PDF).
• Pay attention to portion sizes.
  Eating the right amount is just as important as choosing the right foods.
  The Smart serving and portion size guide can help you better understand how much to eat.
